Fix for marooning in filters page for bootstrap5

[dunxd]

I think I've resolved the issue discussed with PR #47. Please check as I think you have a better understanding of the filter function than me.

Not quite there yet. I changed filter.navlink to include the filter=1 part now, as it may be rewritten if you use route urls - so there's no need to add it in the template anymore.

Also there's probably no need to check for isFilterPage if you change the logic a bit - at least as long as you stick to doT-style templates. The main reason I added that variable was for the twigged template, so that I could load a different template altogether.

In the bootstrap2 template, the logic is:

• do you have it.filters or not?
  • if so, show the current filter(s) that apply (glyphicon-filter)
• if not, do you have books or not
  • if not, show link back to booklist (glyphicon-list)
  • if so, show link to filter page (glyphicon-link)

Does that help?

And please have a look at https://stackoverflow.com/questions/10176875/add-gitignore-to-gitignore and others like it to ignore your .gitignore changes locally, and not send them over with every PR again ;-)

I think I have the gitignore thing working now - I've added the stuff specific to me to .git/info/exclude and will try to remember to do that if I add anything else in future that shouldn't be copied into the repo.

Regarding the logic - I have the filter buttons in the same navbar as the sort controls, so I do need logic to determine whether to show the whole navbar or not. Later logic determines whether to show the filter buttons. Without isFilterPage the navbar is missing on the page listing filter choices.
