Обсуждение: Fix pagination link handling in search results
Hi!
Thanks for maintaining pgweb.
I noticed this issue when searching mailing lists. I did not test the change in the application, but I did test the logic in a local python console and I think it's right.
Commit message of the attached commit follows, explaining the issue:
Fix pagination link handling
If the total number of search results is divisible by the page size, the page count is mis-calculated and there's a link to an additional page of results, even though there are no more results and that page is empty.
See issue here: https://www.postgresql.org/search/?m=1&q=contrib&l=76&d=365&s=r&p=2
At the moment, this has 20 results but a link to a second page, which is empty with a label of "Results 21-20 of 20." Previous and Next works still work fine, but that second page does not really need to be there.
This changes the page count calculation to avoid this issue.

Funny enough, it's kind of tough to test the search features locally :( > Commit message of the attached commit follows, explaining the issue: > > Fix pagination link handling > > If the total number of search results is divisible by the page size, the > page count is mis-calculated and there's a link to an additional page of > results, even though there are no more results and that page is empty. > > See issue here: > https://www.postgresql.org/search/?m=1&q=contrib&l=76&d=365&s=r&p=2 > <https://www.postgresql.org/search/?m=1&q=contrib&l=76&d=365&s=r&p=2> > > At the moment, this has 20 results but a link to a second page, which is > empty with a label of "Results 21-20 of 20."

I was able to reproduce the issue and do agree that it is a bug. I have not been able to verify your solution yet but I have it on my TODO. Thanks, Jonathan
