Extension talk:Page Schemas

A couple of errors
Forgive me, I am new to MediaWiki and this extension. This might be blindingly obvious to others, but I am stumped. I'd like a pointer where to look in my configuration to address two issues:

1) Creating or Editing a schema throws the following errors: Warning: Illegal offset type in isset or empty in /home/eat/wiki/includes/Html.php on line 698 Warning: Illegal offset type in isset or empty in /home/eat/wiki/includes/Html.php on line 706 Warning: Illegal offset type in isset or empty in /home/eat/wiki/includes/Html.php on line 296 Warning: Cannot modify header information - headers already sent by (output started at /home/eat/wiki/includes/Html.php:296) in /home/eat/wiki/includes/WebResponse.php on line 75 Generate Pages throws the following [58a916bae31fcc06947f7174] /index.php?title=Category:Cheese&action=generatepages Error: Call to undefined method PageSchemas::titleString

 * I'm not sure about the first one, but the second one is a real problem, and it's my fault. I removed the function PageSchemas::titleString in the recently-released version 0.7 of Page Schemas, not aware that it was being used in the Page Forms extension. I removed this usage from Page Forms last week, but I haven't released a new version of Page Forms yet - so the current versions of Page Schemas and Page Forms are incompatible. The easiest fix for this is to switch to the latest Page Forms code, using Git, if you know how to do that. Once you have this problem fixed, in one way or another, hopefully the rest will work as well. Yaron Koren (talk) 13:40, 28 September 2022 (UTC)


 * That does indeed fix the second issue. Still no idea why the first issue exists. It only appears if
 * ini_set( 'display_errors', 1 );
 * exists in LocalSettings.php, so it can be mostly ignored I suppose 90.160.205.38 20:41, 28 September 2022 (UTC)

Only for editors
Is it possible to use    in combination with Page Schemas?


 * What is "onlyforeditors"? Yaron Koren (talk) 17:22, 15 May 2018 (UTC)

I think I can help here by clarifying things: what we would like to have is something like this in the schema XML:  This should result to this in the generated template: {#if:| ! somefieldlabel Is this possible? Does it need a code change? If yes, any hints where and how complex?
 * - class="somehtmlclassname"
 * somepropertyname::}}


 * I don't think there's any way to add an HTML class to a generated table row, unfortunately. I don't know how complex it would be to add it. Yaron Koren (talk) 17:23, 23 May 2018 (UTC)

Change allowed values
If I change the names of the allowed values (e.g. to correct a typo) I get the message "[new name] is not in the list of the allowed values of the ... property". Is it possible to change the spelling of the allowed values?


 * The ReplaceText extension may help with this, if I understand the issue correctly. Yaron Koren (talk) 14:26, 19 March 2018 (UTC)

Customise templates
This is similar to a query back in 2014 but I wondered if anything had changed. I would like to add some custom information to the template, but each time I edit the Schema and generate pages, this is lost. (In my case I'd like to add a Cargo query which displays a location on a map.) Is this possible, without having to manually cut and paste each time? Thanks. Jonathan3 (talk) 23:41, 21 November 2016 (UTC)


 * Still no. There's a lot that could be improved in Page Schemas - it's not that popular an extension, I don't think, so it hasn't gotten a lot of attention. Yaron Koren (talk) 03:30, 22 November 2016 (UTC)


 * That's a shame, as the ability easily to change the data structure and the associated template/form pages seems invaluable. I found it very useful at the start when working things out. Jonathan3 (talk) 00:37, 3 December 2016 (UTC)


 * Regarding "popularity", I've tried both the manual and the schema way, and this extension has the potential to make really smooth the use of of Forms. And this little feature is the stumbling block.  Untill it's fixed, you have to edit + generate forms in 2-steps, to redo customizations.

tooltips in page forms using Cargo
--138.232.124.69 12:42, 28 March 2018 (UTC)

Since switching to Cargo from SMW the tooltips I have on my forms don't display as tooltips. They're just text on the page, even though the schema generator has this notation in it "Show description as pop-up tooltip"


 * I'm guessing that the template is calling #info. That's no longer working because #info is defined by SMW (strangely, SMW includes its own tooltip functionality). I would recommend installing the SimpleTooltip extension - then, if you recreate the template from the schema, the #info calls will hopefully get changed to #tip-text calls. Yaron Koren (talk) 14:01, 2 June 2017 (UTC)


 * that does it! The new class is actually:  #tip-info  cheers --Anrake (talk) 14:53, 2 June 2017 (UTC)

Jobs not running
I've had several Page Schemas jobs in the queue for over 3 days. I'm adding a new category and want to use it to scaffold the template, form and new semantic properties. I've tried all the tricks I can find to force them to run including changing job_attempts to 0, various combinations of $wgJobRunRate and $wgRunJobsAsync but nothing seems to work. Tonight I tried to delete the jobs and run Generate Pages again, but they still got stuck. I even ran update.php and rebuilt the Semantic index. The last time I used Page Schemas was probably last July. Are there any ideas to force these to run?

Unregistered users may see only certain fields
Is it possible to configure Page Schemas/MediaWiki so that unregistered users are able to see only certain fields?


 * No. Yaron Koren (talk) 00:41, 26 March 2018 (UTC)


 * To bad. Is a woraround possible? --138.232.124.69 12:42, 28 March 2018 (UTC)


 * Could you explain what the need is? Yaron Koren (talk) 19:15, 28 March 2018 (UTC)


 * I'm using Mediawiki in combination with PageSchemas to create a DB. Until now the DB is only a working tool, but we plan to go online in a few weeks.

Since it is for the moment a private DB there are some fields in our schemas containing notes that are supposed to be only private notes for the contributors.

Is it possible to cofigure MediaWiki/PageSchemas in such a way, that certain fields may not bee seen by unregistered users? --93.70.101.215 07:45, 1 April 2018 (UTC)


 * Oh, I see - you mean actual data fields; I thought you meant fields within the Special:EditSchema form. In either case, the answer is no. If there's data that you don't want certain users to see, the best solution is to keep it out of the wiki altogether - and it may make sense to create a separate, more restricted wiki to contain just that data.

Issue Installing to MW 1.31
Should this extension work with 1.31?

I Downloaded the version of this extension marked for MW 1.31.

Trying to run update.php.

 * Yes, using the "ExtensionDistributor" with any of my extensions is generally not a good idea, because it just represents a random, and usually outdated, snapshot. I would try using the latest Page Schemas code instead. Yaron Koren (talk) 15:13, 25 June 2018 (UTC)

More Documentation?
Besides the video and the landing page for this extension, is there any other source of documentation? Ankostis (talk) 14:06, 19 September 2018 (UTC)


 * There's also this, though it's not much. Yaron Koren (talk) 01:05, 20 September 2018 (UTC)

Page Schema Infobox Templates
Can you set a template created by Page Schemas to output an Infobox or that can only be done by editing the source code after Page Schemas creates the template?


 * What do you mean by an "infobox"? Yaron Koren (talk) 16:13, 15 November 2018 (UTC)

Schema Not Saving
I have two issues, really.

1) I've found a scenario where the "Save Page" function in the "Edit Schema" tab no longer actually saves the schema.

If I create a schema from a blank category, and use the form in "Edit Schema" to do so, everything is great.

If, however, I edit the schema using the "Edit" tab, then I'm no longer able to save changes made to the schema using the "Edit Schema" form. The schema is locked to the revision created during the manual "Edit".

I first noticed this when I was attempting to manually fix another issue...

2) When adding a Semantic property of type "Telephone Number", the "Edit Schema" form would show it in the dropdown as "Telephone 2ber" if it was the 2nd field, or "Telephone 3ber" if it was the third, and so on. That strange "2ber" or "3ber" or "7ber" would show up in the raw schema XML.  I changed it manually in the "Edit" tab, but then realized that I was locked to that revision.

I thought I was losing my mind for a bit, but I was able to determine the above.

Any thoughts?

I enabled debug in LocalSettings.php, but no messages show up.

--dvicci (talk) 02:23, 29 December 2018 (UTC)


 * Sorry about that! No, you're not losing your mind. I actually had a fix for this right after you reported it, but forgot to check it in until now. I just checked it in. Yaron Koren (talk) 19:22, 14 January 2019 (UTC)

Values parameter + Documentation
How do I enter multiple values for a dropdown input type? I can easily get this working with Page Forms but can't figure out what to put in the field to make this happen in Page Schemas. It would be very helpful to have some documentation for this plugin that outlines how to write parameters and values for each input type as well as providing direct examples. Thx. TiltedCerebellum (talk) 05:13, 5 June 2019 (UTC)


 * Sorry for the long delay. I think you're using neither Cargo nor SMW, so the set the values has to be defined for the form input itself. If you add into the big "Enter parameter names ..." input something like "values=A\,B\,C", that should hopefully work. Yaron Koren (talk) 16:26, 12 August 2019 (UTC)

Mysterious error
When I try to create a schema, I get this error after trying to save:

I've turned on PHP debugging and nothing shows up. I don't know how to debug this.


 * If you add "$wgShowExceptionDetails = true;" to LocalSettings.php, it may produce a more useful error message. Yaron Koren (talk) 15:53, 12 August 2019 (UTC)

Link to schema value?
If I were to include a field in the schema that provided a unique ID for the page could I link to the page using the value of the field?


 * If you're using Cargo or SMW, you can do it by querying on the ID field... if I understand your question correctly. Yaron Koren (talk) 18:35, 3 October 2019 (UTC)

Template from Schema with display="nonempty"
The template code seems to be missing two brackets closing the #if statement.

This is the schema:

This is the template generated:

Installed versions are: MW 1.33.1, PHP 7.3.10 (cgi-fcgi) , SMW 3.1.1 , Page Forms 4.6 , Page Schemas 0.4.9 , ParserFunctions 1.6.0

Maybe it is related to the other problem i am having?

Thanx for your great work! Any suggestions? Andi 3ö (talk) 16:03, 6 December 2019 (UTC)

No permission on Create Schema
Hi, I haven't used SMW since 2008 so forgive me if this is something obvious.

After installing the extension the Create Schema button is showing up in a Category page, but on clicking it I only get:

Permission error

You do not have permission to edit this page, for the following reason: The action you have requested is limited to users in the group: Users.

This is as admin, staff, etc. across multiple users. I edited LocalSettings.php with:

$wgGroupPermissions['user']['generatepages'] = true;

and added:

$wgGroupPermissions['user']['editschema'] = true;

$wgGroupPermissions['user']['createschema'] = true;

for safe measure. Also tried with 'staff' and 'admin' but the message never changes.

Thanks!


 * What version of Page Schemas and MediaWiki are you running? Yaron Koren (talk) 02:41, 3 March 2020 (UTC)

MediaWiki 	1.31.6

PHP 	7.2.24-0ubuntu0.18.04.3 (apache2handler)

MySQL 	5.7.29-0ubuntu0.18.04.1

Page Schemas	0.5 (d493e62) 08:25, 26 February 2020 Thank you, sorry for not noticing your response earlier.


 * Sorry about that! It turns out that I accidentally inserted a major bug into Page Schemas a few weeks ago - permissions for "action=createschema" were reversed for those using MediaWiki 1.32 or lower. I just checked in a fix for it - hopefully it works correctly now.


 * By the way, there is a 'generatepages' permission, but there's no 'editschema' or 'createschema' permission - the simple 'edit' permission is used for those. Also, there's no 'admin' user group, at least by default - you're probably thinking of 'sysop'. Not really related to this problem; I just figured I should mention it.

Possible conflict on using Page Schemas with both Cargo and Semantic Mediawiki
Hello,

I'm currently working on a project that utilizes both Cargo and Semantic Mediawiki extensions. The problem I have is that when I define the XML schema and generate the Model and Category pages, the Cargo table declaration is removed from the Model page. This happens when I load the SM extension below the Cargo extension and be resolved if I reverse the order.

My question is: is this behavior work as expected? Do we have side effects regarding the order of the two extensions?

Thank you so much,


 * Yes, when both Cargo and SMW are installed, Page Schemas just goes with SMW. I could change it to just go with Cargo, but having it support both at the same time would take a good amount of work, unfortunately. Yaron Koren (talk) 13:07, 27 August 2020 (UTC)

'Generate pages' action leads to Internal Error
PageSchemas generates an error when attempting to create new schemas: After defining the schema parameters, clicking the  button generates a MediaWiki error page describing an internal error (PageSchemas, not Apache).

It's not really clear to me whether the cause of the error is Page Schemas or Semantic Internal Objects, so I re-installed both and re-ran  but no change in status. P.S. Existing schemas work just fine as-is, but cannot be modified (same error, if attempted).

 * That fixed it! And I appreciate the insight; we weren't using the extension, it had been installed for eval & testing, which never happened of course, and then I'm guessing a recent extension upgrade created an incompatibility that hadn't existed before -- Milliard Gargantubrain (talk) 04:23, 24 September 2020 (UTC)

One local setup is done with WinNMP 20.11, Mediawiki 1.36.0, with PHP 7.4.13, MariaDB 10.4.17, SMW 3.2.3, Page Schemas 0.5.2, Page Forms 5.2.1 The other failing setup is with XAMPP-portable, Mediawiki 1.36.0, PHP 8.07, MariaDB 10.4.19, SMW 3.2.3, Page Schemas 0.5.1, Page Forms 5.2.1

I guess there's something wrong with my Namespace configuration but I have no idea what.

Thanks in advance for any help!


 * Sorry about the problem. It has nothing to do with your configuration - this is was a bug with the handling of MW 1.36 and higher that wasn't fixed until about a month ago. There hasn't been a new version released since the fix, so you'll have to use the latest Page Schemas code. Yaron Koren (talk) 20:07, 21 June 2021 (UTC)


 * thank you for your prompt reply! That fixed it (I didn't notice my online version wasn't using MW 1.36, hence my fix on the local versions) Thanks again for your great work!


 * I hadn't fully tested until now: creating the schema works fine now but when I try to generate the pages I get this error, in my WinNMP-setup (not when doing the same in the MW 1.35 online version).

 * It looks like this is a bug in SMW - specifically, on this line, the code shouldn't be using $wgContLang any longer, since it was removed in MW 1.36. I would let the SMW developers know about the problem. Yaron Koren (talk) 13:53, 27 June 2021 (UTC)
 * Thanks again. I reported the problem and made another local setup for myself, using MW 1.35, so I can use your great extension.

Cargo query and Page Schemas
Hello, I need to include a Cargo query in my Template. I have a Template called "Project" and one called "Activities". Each Project can have multiple Activities. I do not want to manually select the Activities when editing a Project. I just need to show them on the Project page via a Cargo query.

I could manually insert the query in the Template but it would get deleted if I modified the Page Schema. Am I right?

Is there a way to accomplish this?

Thank you. Carlo


 * Yes, regenerating the pages would wipe out whatever changes you made. At some point, if the template or anything else can't be created by Page Schemas, then you'll have to switch to just editing these pages manually, unfortunately. Yaron Koren (talk) 14:56, 14 October 2021 (UTC)

Missing #set function in multiple instance templates?
I created a schema with a multiple instance template and observed that hidden fields defined in the multiple instance template are displayed, actually as simple unformatted text. Comparing the template code with one of a common, single instance template, it seems that a call of the #set parser function is missing. At least, adding #set fixes the problem and the fields don't show up anymore as expected.

Template code generated by Page Schemas:

{| class="wikitable" P-PPN:: E-PPN:: [...]

Fixed template code after inserting the #set-call:

{| class="wikitable"


 * Regular properties (outside of #subobject) shouldn't be getting set at all in multiple-instance templates - so the real bug is that it included those lines in the first place, it seems to me. I would just delete them; you don't need a #set call in their place either. Yaron Koren (talk) 14:58, 14 October 2021 (UTC)
 * Thanks for your help! Deleting them solves the problem. MMFSoftwares (talk) 21:12, 14 October 2021 (UTC)

Custom delimiters not applied in generated forms and subobject section of templates.
I defined a custom delimiter (_) in text with autocomplete fields. In the template, the expected #arraymap function is included but in the form definition the parameters list and delimiter= seems to be missing. Also, the sep parameter in #subobject does not contain the customized separator.

TypeError: Illegal offset type in isset or empty
Hello! Having a PHP error, and I can't quite figure my way to debugging it.

When creating or editing a schema I get...

Error

Versions

 * PageSchemas version: `REL1_37` branch, though Special:Version shows
 * MediaWiki 1.37.1
 * PHP 8.0.8
 * SMW 4.0.0
 * Page Forms 5.3.4


 * That looks like a bug in line 194 of SMW_PageSchemas.php, in Semantic MediaWiki. And it looks like a bug that I introduced, a very long time ago! I wonder how no one noticed it until now. Yaron Koren (talk) 01:18, 8 March 2022 (UTC)
 * was any fix found for this? Sneeze5555 (talk) 07:50, 28 July 2022 (UTC)
 * I believe that line I mentioned, line 194 of SMW_PageSchemas.php, which currently looks like:


 * ...should instead look like:


 * And actually, looking at the code now, it looks like two other lines in that same file, 217 and 240, have the same problem. Yaron Koren (talk) 13:04, 28 July 2022 (UTC)

Understanding Sections
Can you explain two things please ?


 * 1) If the output format is set to Sections - what is that supposed to do ?
 * 2) What does the Add Section button achieve ? I tried to play with it but simply got this error when saving the changes Warning: count: Parameter must be an array or an object that implements Countable in xxxxxxx/extensions/PageSchemas/includes/PageSchemas.php on line 247

 * Sorry about that second problem - I just checked in what I think is a fix for it. But the "sections" format is supposed to make every field a separate section of the page, i.e. the field name becomes a section name (with the '==' around it), and then the field value is the contents of that section. Yaron Koren (talk) 14:03, 31 May 2022 (UTC)
 * Brilliant. Thanks. Makes sense (though not something I can think of a use case ATM). 91.85.121.33 21:03, 31 May 2022 (UTC)

Errors with Page Schema
I have been experimenting with Page Schema for a couple of days and getting to understand it better. I currently cannot get a Form to present itself as expected for a Library application I am building. I start by entering a unique book title, this end up appended to the Page title.


 * 1) I get no Field for the book Title but get a Field Name and Label,
 * 2) all field 'names' and field Labels appear concatenated after the field input box, Form input screen says  Label will be before the field
 * 3) One field I have specified as a Dropdown but the dropdown is part of the next field,
 * 4) there is no label for the last field on the page,
 * 5) even though I have marked the check box for 'pop-up tooltips' the text appears under the field (and not easy to read)
 * 6) All dropdowns are empty.

How are dropdowns meant to be populated? I assumed they would be taken from the Cargo specification where you need to enter the allowable values.

I am using Mediawiki 1.36.2, Page Schemas 0.6 and Page Forms 5.3.4

Thank, Robert 119.224.101.52 23:18, 14 July 2022 (UTC)


 * That's pretty bad. You are using somewhat old versions of Page Schemas and Page Forms, so I encourage you to get the latest versions of these extensions, to make sure that that's not the issue. (Don't worry, they will still work with MW 1.36.) I hope that will fix at least some of these problems... Yaron Koren (talk) 13:55, 15 July 2022 (UTC)


 * I have had both Extensions updated and it made little to no difference, so I started changing some options. I found the Culprit, is the "Allow multiple instances of this Template" option. If this is checked, the form is unuseable. I have since worked out I did not want that option anyway, not understanding exactly what is was doing. However, there are still two items that do not appear to behave as expected: 1. Pop-up tooltips, they still appear under the Field Name/Label, and 2. I am still intrigued why the Field Name and the Field Label are both displayed, one after the other in front of the Field box. I would have thought if you do not specify a Label, the Field Name will be used, otherwise just the Label, but never both straight after each other. It appears to just be a cosmetic thing so not all that important. Robert


 * I tried replicating these problems with the current versions of Page Schemas and Page Forms, but I can't replicate any of the these many problems you list. I'm not sure how to go about debugging this - what are the biggest problem(s) you're seeing right now? Yaron Koren (talk) 14:45, 18 July 2022 (UTC)


 * I now only get the big errors if I have "Allow multiple instances of the Template" checked, that makes the form unuseable. So the two items that remain are, the field Name and Label are both displayed in front of the field. This causes confusion Why does the Field name display? Should that not just be an internal identifier? Secondly the Tooltip text does not seem to be working as a pop-up, it just displays under the Field Name/Label as a single line of text. Some of mine are of reasonable length placing the Field a long way from its Label. Is this the same issue as logged on 28 March 2018? Do I need to install an additional Extension? Thanks,  Robert


 * I don't know why you're seeing both the field name and the label, and I can't replicate that problem. (I also can't replicate the problem with "allow multiple instances".) Could you pastebin the generated form and template? That might be helpful. As for tooltips - yes, you need an extension; the best one to use for that is RegularTooltips. Yaron Koren (talk) 13:17, 19 July 2022 (UTC)


 * This is the Form

This is the "Books" form. To create a page with this form, enter the page name below; if a page with that name already exists, you will be sent to a form to edit that page.



Free text:

And this is the Template

Thanks for your time on this, I note that the majority of the Form code does not display but it is visible if you look at the Source Code of this page. I will be extending this table today, merging in another table that no longer needs to be separate. A useful feature of Page Schema would be 'Add a field above' just like you have in "Create a Class". Robert


 * Thanks, that's helpful. Now I see the issue: you filled in that "Text that will be printed before the field:" value for each field. That's the issue - I confess that I don't remember what that is for, but it's not the field label - it's text that's meant to go before it. So if you just blank those values, the problem should go away. And I agree that being able to add fields above would be helpful, as would being able to rearrange them.

Any one have issues used with PHP 8.0.24 ? Else I need to downgrade to use PHP 7.4.X.
