Sir please add topic namespace as well

No. See reasons in T168765#3514961.

Change 370990 had a related patch set uploaded (by Urbanecm; owner: Urbanecm):
[operations/mediawiki-config@master] Create a few of namespace aliases for hiwikiversity

https://gerrit.wikimedia.org/r/370990

Per T131754 and T133440, ne.wikibooks and hi.wikibooks use Subject: and not Topic: as namespace English alias for विषय:

@Jayprakash12345 what do you think to be coherent with hi.wikibooks to call the विषय: namespace Subject: instead of Topic: ?

That would allow to use Subject: alias without any bad title error.

The Meaning of Topic are different. Its meaning outcome from Purposes:-
Topic - विषय (In An Education)
Topic- मुद्दा (In Political)

It is right Subject have also meaning विषय.

Sir, Now Drop the Topic namespace. As you early told me that it is not using on Eng wikiversity. They using Portal for it. So we will also use Portal for it instead of Topic.

Thank you

@Dereckson Sir, Are there any problem to merge patch.

Nope, they arent. We were discussing about this privately and decided to do the deploy. As next deployment window will be at Monday, I'll use it.

@Jayprakash12345: On which exact page (=link) are they not shown? Can you provide one example page (=link) that is "not shown"?
Exact steps to reproduce problems are welcome, see https://mediawiki.org/wiki/How_to_report_a_bug - thanks! :)

Sorry Sir, I Explain it more precisely.

I was made some pages on beta.wikiversity with prefix School: namespace. Now Hindi wikiversity are open. and pages are imported. But School: namespace are not redirecting on local namespace विद्यालय: . So this task had open to make alias. Now school: are redirecting विद्यालय. Which is good. But the pages which was imported. They all are disappeared. We can see them on main namespace (I provided link above). When I click on School:Page. It redirects on विद्यालय:Page. And I am seeing that Page are not exist.

Here two problem arise.

1. School:Pages are currently in main namespace. So someone click Random Pages. They comes.
2. Where the School:pages are gone. When we open School:Pages It will redirect on विद्यालय:Pages .

Hi,

What are we, DBAs, supposed to do here @Jayprakash12345?

@Marostegui Sir, who can check School:Pages in Database. Can you give me path?

@Jayprakash12345: Again, please do provide specific test cases with full links, so someone else could reproduce the problem without any need for interpretation.

If I understand correctly, I go to https://hi.wikiversity.org/w/index.php?title=विशेष%3Aउपसर्ग+अनुसार+पृष्ठ&prefix=&namespace=0&hideredirects=1 and click e.g. on "School:इलेक्ट्रॉनिक्स" which links to https://hi.wikiversity.org/wiki/School:इलेक्ट्रॉनिक्स , but I end up on https://hi.wikiversity.org/wiki/विद्यालय:इलेक्ट्रॉनिक्स which is empty.

So the question is probably if the page School:इलेक्ट्रॉनिक्स (and its content) still exists but can currently not be reached in the browser, as you get redirected to विद्यालय:इलेक्ट्रॉनिक्स ? And how to fix that so the content can be reached in the browser?

And that pages starting with School: are still shown when searching in the main namespace?

Yes Sir

Heff, I think I know what's the issue there (namespaceDupes.php required).

@Marostegui Nothing, from my POV.

@Urbanecm thanks, I don't really understand what I am asked to find out to be honest.

Thank you sir, Now it is working fine.
