Template talk:Get QID
Redirect doesn't work when substituted
[edit]I recently edited the template to allow substituting, but substituting doesn't seem to work on redirects e.g.
{{Get QID|Wikipedia}}
→ Q52
and
{{Get QID|WikiPedia}}
→
This doesn't seem to affect transclusion. Any idea why this happens?

- To clarify, the substitution problem only occurs in case 4:
{{Get QID|Wikipedia}}→ Q52{{subst:Get QID|Wikipedia}}→ Q52{{Get QID|WikiPedia}}→ Q52{{subst:Get QID|WikiPedia}}→{{Get QID|Maryport New Lighthouse}}→ Q29571349{{subst:Get QID|Maryport New Lighthouse}}→ Q29571349{{Get QID|qid=Q52}}→ Q52{{subst:Get QID|qid=Q52}}→ Q52
- I'll think about it. Tomastvivlaren (talk) 22:03, 17 March 2022 (UTC)
I guess the nice beta Module:Redirect causes the problem,allthoguh it can be substituted:{{#invoke:Redirect|main|Universes}}→ Universe{{subst:#invoke:Redirect|main|Universes}}→ Universe

After this edit of the template it works:
{{Get QID|Wikipedia}}→ Q52{{subst:Get QID|Wikipedia}}→Q52{{Get QID|WikiPedia}}→ Q52{{subst:Get QID|WikiPedia}}→ Q52{{Get QID|Maryport New Lighthouse}}→ Q29571349{{subst:Get QID|Maryport New Lighthouse}}→ Q29571349{{Get QID|qid=Q52}}→ Q52{{subst:Get QID|qid=Q52}}→ Q52
[ I can not explain why. I used the {{if empty|a|b}} instead of {{#if|a|a|b}} to avoid calculating the "a" twice. When combined with safesubst, the substition all of a sudden works. @Qwerfjkl: Tomastvivlaren (talk) 22:53, 18 March 2022 (UTC)
- It may be due to whitespace, then. Templates retain whitespace passed as a parameter, but parser functions don't. ― Qwerfjkltalk 07:05, 19 March 2022 (UTC)
