Cannot Create Cargo Tables

 * MediaWiki 	1.39.2
 * PHP 	7.4.33 (litespeed)
 * MySQL 	8.0.32-cll-lve
 * ICU 	64.2

Using Page Forms 5.6.

Tried to create a basic one-parameter template/table (a single text field). Neither SSH nor Create Data Table worked. I confirmed the MediaWiki user has all permissions to the MediaWiki table.

Pins on Openlayers map not clickable on mobile
I can't get the pins on Openlayers maps to be clickable on mobile (or whatever the word is - touchable?). The same query with Google maps works all right. Jonathan3 (talk) 13:23, 9 January 2023 (UTC)

Stripmarkers displayed in query output when using Template Styles Extension on wikitext field
We frequently use templates to inject additional information or styling into wikitext, some of which gets stored in the Cargo tables. When the styling is handled by Common.css, all behavior is normal. If the CSS is moved such that it's managed by the TemplateStyles extension, then the Cargo Query will begin to display Strip Markers in the output. How can this be resolved without moving styling back into Common.css?

I attempted to add a link to an example of this error, but Mediawiki would not allow me. 67.191.180.153 18:47, 10 January 2023 (UTC)


 * Do you mean that this error can be seen on a public wiki? If so, could you put the URL here without the "http" part? Yaron Koren (talk) 03:57, 11 January 2023 (UTC)
 * I set up a demo of the error here. The page is a query which displays a wikitext summary. Cargo behaved as intended in the past, but after introducing TemplateStyles, cargo now displays the stripmarkers for the wikitext fileds' template calls. www.dustloop.com/w/User:PrivateTarkus/sandbox 67.191.180.153 05:51, 12 January 2023 (UTC)
 * As a temporary solution, I've disabled Templatestyles for templates which frequently appear within Cargo fields. As expected, this workaround does resolve the issue for now. It seems to be a problem of cross-compatability between Templatestyles and Cargo, @Yaron Koren. 67.191.180.153 14:05, 16 January 2023 (UTC)

Sort from largest to smallest
Hello, how can I sort the rows in the table so that the table starts from 10 to 1, and not 1 to 10. I use Lua. -- Oleksii 212.80.47.83 07:47, 18 January 2023 (UTC)


 * Just add " DESC" at the end of the "order by" value. Yaron Koren (talk) 19:02, 18 January 2023 (UTC)

Compound Query ordering
Cargo 3.3.1

MW 1.39.0

Is it possible to set the Order by so that it affects all the queries in a compound query?

Example query

This has two queries, but the results are displayed in order for each individual query. Temujen510 (talk) 20:12, 21 January 2023 (UTC)


 * Unfortunately, no. Yaron Koren (talk) 01:22, 23 January 2023 (UTC)

Page references in columns not updated after moving page
What is the expected behavior for a Page data type in a Cargo column? I had expected that when I move a page, all references to that page in Cargo table columns would then be updated, but that doesn't appear to be happening. What is the best approach to keeping two tables, one of which references the other's page name, in sync after page moves? Nicholasalanbrown (talk) 02:08, 5 February 2023 (UTC)


 * No, what's in Cargo just reflects what's in the wikitext (well, usually). You can do something like joining on the _pageData table and using its _pageNameOrRedirect field, but I would recommend just using the Replace Text extension. Yaron Koren (talk) 03:27, 6 February 2023 (UTC)

Hide "Go to date" part of calendar
This part of the calendar doesn't look well when the screen is narrow. What is the best way to hide it? I see that one of the calendars linked to on the documentation page is https://icannwiki.org/IG_Hub/Calendar and it does not have the "Go to date" part. Thanks. Jonathan3 (talk) 08:25, 14 February 2023 (UTC)


 * I'd still be interested in a parameter to remove this. It only appears on recent Cargo versiosn (e.g. on https://discoursedb.org/wiki/Opinion_calendar but not on https://icannwiki.org/IG_Hub/Calendar). I've managed to hide it with CSS, but the lack of id's makes it imperfect:



Link do Drilldown
I am trying to put a link to a pre-filtered drilldown on a wiki page. The link looks fine when I hover over it, but I actually click on it the "&" and other special characters get changed. For example, instead of what it should be and is in the hover over  it becomes , and when I click on it I get an error. How would I build a link to a drilldown in a wiki page? Tenbergen (talk) 16:10, 15 February 2023 (UTC)


 * Right - the only solution I can think of is to make an external link (with the full "http..."), instead of an internal link. Yaron Koren (talk) 16:47, 15 February 2023 (UTC)


 * That works for explicit links, thanks! I was trying to generate the links inside a query (I have an aggregate query that provides counts, and want to link to a drilldown that would list the values that are counted). Some of the values have spaces in them, so the only way I can think of to make this work is to enable the "replace" function in SQL and then turn the spaces into "+" to generate the link. This works, but REPLACE seems to be an especially problematic function to enable. Is there a better solution to generate that link? Tenbergen (talk) 18:06, 15 February 2023 (UTC)
 * Oh, I see. That seems fine - I don't see anything wrong with using REPLACE. Yaron Koren (talk) 20:10, 15 February 2023 (UTC)


 * My concern with enabling the replace function was that it might allow re-writing things inside an SQL query, e.g. SQL injection. Maybe I am being paranoid. Tenbergen (talk) 19:17, 16 February 2023 (UTC)

"Recreate data" issue with Mediawiki 1.39.1

 * Wow! It must have been a long time since anyone tried to use the "tree" format, because there were various things that were not working there - that "isList" check was just one of them. I just checked in a fix, so it all should work better. Yaron Koren (talk) 21:37, 16 February 2023 (UTC)


 * That fixed it! Yes, it's been a problem for a long time, I just had not got back to troubleshooting it. Thanks! Tenbergen (talk) 00:12, 17 February 2023 (UTC)

Add table row [edit link] when using format=template
I'm displaying results in a table, using format=template for the rows. How can I add a Page Forms edit link next to each row? I know this is possible using format=table by adding the parameter "edit link=yes", but I haven't figured out how to do it when using format=template. Note that I'm using unique numbers as the pagename for each country.

Template:Country

Template:Country row









Template:List of countries

Database error when trying to concat a list field in Cargo Query
I was doing some troubleshooting and tried to run a query in the Special Cargo Query. The query is where SecretaryTo is of type "List of Page, delimiter: ,". When I run the query with a text field I get no error. The query runs and provides sort of the expected result when I just use the field, no Concat. But I think I have some blanks or other problem, so I wanted to add the xs before and the ys after. When I do that, get a red crash:

I suspect something about lists isn't handled right in this context. Tenbergen (talk) 23:37, 22 February 2023 (UTC)


 * A list field is not a string, so it's not surprising that the CONCAT failed. (And actually, list fields aren't even really fields at all - they're "virtual" fields.) I think you can get this query working by replacing  with  . Yaron Koren (talk) 15:45, 23 February 2023 (UTC)


 * Thanks, I got it working with __full. Error Fatal exception of type "Wikimedia\Rdbms\DBQueryError wasn't very helpful, though, and not all query builders would have access to enable debug to show something more helpful. So, I posted it in case you want to turn the error into something more descriptive. Thanks for your help! Tenbergen (talk) 22:31, 2 March 2023 (UTC)

Duplicate results in Special:Drilldown
Any news on this?


 * Extension_talk:Cargo/Archive_June_to_August_2022

 * No, sorry - I'm guessing it's still a problem? Yaron Koren (talk) 14:49, 2 March 2023 (UTC)
 * Yes, I'm afraid so - quite a big one, for some tables at least.

Hidden category for pages containing Cargo queries
Is it possible to set this up? Thanks. Jonathan3 (talk) 22:59, 6 March 2023 (UTC)


 * The cargo_backlinks DB table holds the IDs of all pages containing queries - maybe that's good enough? Yaron Koren (talk) 16:55, 7 March 2023 (UTC)
 * That sounds all right. Can it be queried from a wiki page? Jonathan3 (talk) 21:58, 8 March 2023 (UTC)
 * Not really with the current software... what's the ultimate goal? Yaron Koren (talk) 23:25, 8 March 2023 (UTC)
 * I'm considering changing a Cargo table's structure, and wanted to update queries where necessary. I considered writing a short script querying the cargo_backlinks table, but there aren't that many Cargo queries so I think I can just use Extension:ReplaceText (to search for ). Jonathan3 (talk) 22:39, 16 March 2023 (UTC)

List not populated
Hi! First of all, thanks for creating this extension :D I have some issues however, that I'm trying to sort out. Right now, my main table is not completely getting populated. It should have ~250,000 rows, but it just stops, sometimes at 300, sometimes at 17,0000, but never near expected. I have tried creating replacement tables, but has no effect. Does anyone by any chance know what could be the issue here? Dajasj (talk) 14:55, 16 March 2023 (UTC)


 * I would try populating the table from the command line, by calling cargoRecreateData.php - it might work better, or it might point to whatever is crashing the recreate process. Yaron Koren (talk) 15:01, 16 March 2023 (UTC)

cargoRecreateData.php not working properly with --replacement parameter
I changed a field of an existing table from  to   and ran   with the   parameter. The  table was created, but when switching in the replacement table using the web interface the "NEXT" tables were not dropped (I've not noticed whether that is normal or not) but more importantly no   was created. This meant that the associated Page Form form didn't work.

I dropped the NEXT tables manually and ran  without the   parameter and it all worked as expected.

MW 1.35.8, Cargo 3.3.1 (dac6b0d). Jonathan3 (talk) 21:53, 19 March 2023 (UTC)


 * It sounds like the problem is with the switch call via the web interface, not with cargoRecreateData.php - no? Yaron Koren (talk) 17:20, 20 March 2023 (UTC)
 * Yes, agreed. Jonathan3 (talk) 19:18, 20 March 2023 (UTC)

Error: the string "`" cannot be used within #cargo_query
I started getting this error since Cargo 3.4.1. In my case, I have a label for a column that contains a space, i.e., and then I'm trying also sort on this column with. This used to work. I can fix it by using  instead, but without seeing the query plan, I think I'm experiencing a slower query because it's not using the same value already calculated in the SELECT clause. I don't know if that's really true, though.

What is the recommendation on sorting or grouping by columns with spaces in their names? &mdash; MusikAnimal  talk  16:52, 20 March 2023 (UTC)


 * Sorry about that - yes, backticks were recently disallowed in #cargo_query, for better or for worse. Yes, I would recommend just sorting on the COUNT call. I don't think it will be slower, but I don't know for sure. You could test it with a no-spaces alias. Yaron Koren (talk) 17:29, 20 March 2023 (UTC)
 * I also have the same problem, this is the only code I am managing in my personal wiki using the Cargo extension --Hispano76 (talk) 17:35, 20 March 2023 (UTC)
 * What is the #cargo_query call that is failing? Yaron Koren (talk) 17:42, 20 March 2023 (UTC)
 * That's the thing. i'm not using #cargo_query: anywhere and i only use the image thing; to use the data collected in Special:Drilldown to better manage the articles i make, ehm, like using the special page as a dictionary or database to create lists or people pages. --Hispano76 (talk) 17:49, 20 March 2023 (UTC)
 * So what is the error you are seeing? Yaron Koren (talk) 19:11, 20 March 2023 (UTC)
 * It occurs on two different special page, for example:
 * Special:CargoTables/Personas:
 * When entering one of the conditions of Special:Drilldown/Personas?_single&Genero=Mujeres:
 * Even when recreating the table, the error persists. --Hispano76 (talk) 19:28, 20 March 2023 (UTC)
 * Please try using the latest Cargo code, if you are not already; there have been some fixes for this "backticks" change, including one last week that may fix at least the Special:Drilldown problem. Yaron Koren (talk) 19:47, 20 March 2023 (UTC)
