Empty TemplateData and Lua script error

11

Recently, I have installed a MediaWiki instance locally on a virtual machine that I own. I have also installed VisualEditor, which is working fine.

As I and the future users of this wiki will need to insert references to document the web pages being written, I wanted to install the citation tool (https://www.mediawiki.org/wiki/VisualEditor/Citation_tool) to have something similar to what is being used on Wikipedia.

I have followed the steps carefully:

- I have installed Scribunto, ParserFunctions, Cite and TemplateData;

- I have imported some templates (e.g. Template:Cite_web) from Wikipedia, by using, respectively, the export and the import tools;

- I have specified the configuration message needed for the tool (MediaWiki:Visualeditor-cite-tool-definition.json).

When I use the VisualEditor tool, I see the "Cite" button and the different templates are listed. However, when I select any of the listed templates, no data appears (the template is empty).

In accordance with the troubleshooting part (https://www.mediawiki.org/wiki/VisualEditor/Citation_tool#Troubleshooting), I have tried to make a null edit the content of both the documentation page (e.g. Template:Cite_web) and the source page (e.g. Template:Cite_web/doc) by clicking on Edit then saving directly. This didn't help.

Also, I have tried to follow the different indications on this topic which deals with the same issue, but nothing worked so far.

This problem seems to be related to this bug (https://phabricator.wikimedia.org/T52372), however, the null edit does not resolve the issue.

The following API call is done when I try to open e.g. the web template from the Cite button:

"api.php?action=templatedata&format=json&titles=Template%3ACite web&lang=en&formatversion=2&doNotIgnoreMissingTitles=1&redirects=1"

Which results to this response:

"{

  "batchcomplete": true,

  "warnings": {

  "main": {

     "warnings": "Subscribe to the mediawiki-api-announce mailing list at <https://lists.wikimedia.org/mailman/listinfo/mediawiki-api-announce> for notice of API deprecations and breaking changes."

  },

  "templatedata": {

     "warnings": "The parameter \"doNotIgnoreMissingTitles\" has been deprecated."

  }

  },

  "pages": {

  "23": {

     "title": "Template:Cite web",

     "notemplatedata": true,

     "params": []

  }

  }

}"

Notice that when I click on "Cite" button, I select a template (e.g. Web) and I click on "Insert" even if the template is empty, a reference number is added in the text, but I have an error linked with Lua that is displayed.

Indeed, the file Module:Citation/CS1/styles.css has the following problem:

"Script error: Lua error at line 1: unexpected symbol near '/'."

The file, which comes from Wikipedia (https://en.wikipedia.org/wiki/Module:Citation/CS1/styles.css), has not been modified. By the way, if I remove all the comments, a similar error appears with the code.

Does anyone has any clue on this issue? I really need citation tool to work before adding any content on the wiki, otherwise it will be such a pain to manually add all the references or to update the pages a posteriori.

Hi @Anomie,

Thank you for your response. I tried what you propose, but when I try to change the model of the page to "Sanitized CSS", MediaWiki aborts, giving me the following errors:

Invalid or unsupported value for property background at line 38 character 14.

Invalid or unsupported value for property background at line 44 character 14.

Invalid or unsupported value for property background at line 49 character 14.

The content of the file is exactly the same as the one hosted on Wikipedia (https://en.wikipedia.org/wiki/Module:Citation/CS1/styles.css).

And I still have this "Script error: Lua error at line1: unexpected symbol near '/'." on the page...

Do you know what I'm doing wrong?

On Wikimedia sites the configuration is adjusted to (rather pointlessly, IMO) allow protocol-relative URLs to Commons images. You can either add "https:" to the URLs on those lines in your copy, or copy the changed configuration to your LocalSettings.php.

You're likely still getting the error because those invalid values prevented the content model change.

Thank you for your response. I tried what you propose, but when I try to change the model of the page to "Sanitized CSS", MediaWiki aborts, giving me the following errors: [XQqhYFBk9YTsZsEWS2NcswAAAAY] /index.php?title=X%C3%BCsusi:ChangeContentModel Error from line 78 of /home/ipekchi/public_html/wiki/extensions/TemplateStyles/includes/TemplateStylesContent.php: Class 'Wikimedia\CSS\Parser\Parser' not found . What then should I do, did not understand? Because I do not know where this is located: On Wikimedia sites the configuration is adjusted to (rather pointlessly, IMO)... If possible, explain it. Thanks in advance.

Thank you very much for your quick and useful response, @Anomie!

Now, I can effectively change the model of the page.

However, templates are still missing from the menu on VisualEditor.

When I insert a citation even if the template is missing, a new reference number is added but when I click on it, I have:

"Empty citation (help)<templatestyles src="Module:Citation/CS1/styles.css"></templatestyles>".

I don't understand, as the CSS file has now the mode "Sanitized CSS".

The only thing that, visually, is different from Module:Citation/CS1 is that on my imported page, I see things like:

"<section begin=header />", "<section end=header />", etc.

But I don't think that this is the problem causing all this mess.

I really don't know what to do now...

It sounds like your remaining problems are with VisualEditor rather than Scribunto. You may want to ask on a talk page for that extension.

Hwgen22 (talkcontribs)

Ok I will ask for more help on the VisualEditor page. Thank you again for your help!

For those who will experience the same issue as me, it seems that waiting for jobs to complete is not sufficient, as if the tasks were frozen (or it takes a very long time). Each time I tried and waited, nothing happened.

Manually executing the job tasks will resolve the problems. To do so, run "php <path_to_wiki_installation>/maintenance/runJobs.php".

Note that for each template, you will still need to make a null edit on each template (e.g. Template:Cite_web).

Thanks guys. I'm having the exact same problem. I have changed the file type to "Sanitized CSS" however I am still seeing the same error interestingly on the pages using this Module:

Blanche was born into a working-class family in post-war England, and grew up on a Council estate during the 1950s,<ref name=Interview1>Page Module:Citation/CS1/styles.css must have content model "Sanitized CSS" for TemplateStyles (current model is "Scribunto").</ref> a period he describes as 'grey and flat',<ref name=Ratspike>Page Module:Citation/CS1/styles.css must have content model "Sanitized CSS" for TemplateStyles (current model is "Scribunto").</ref> and lacking in the visual richness available to modern youth. Instead he took early inspiration from cinema, his collections of toy soldiers, and producing drawings of historic warriors on the backs of old rolls of wallpaper.<ref name=Ratspike/>

During the 1960s Blanche was exposed to art and art movements, eventually attending art college, where he entered a course on the strength of his drawings and paintings of battle scenes and prehistoric conflicts,<ref name=Ratspike/> and where he recounts that he was told he "had a romantic spirit, but it would never earn me a living, so there was no point in doing it".<ref name=Interview1/>
