Ability to disable admin pagination

Today I needed to disable pagination for Django admin - and ran into trouble, since there is no explicit option to disable it. There is list_per_page but this only controls how many objects are displayed. Its not possible to set it to None because that throws an exception and setting it to 0 creates a ZeroDivisionException which is also not what I wanted. Finally, I set it to sys.maxint, which sure will be enough.

My idea would be to rename this setting (maybe only in newforms-admin not to break backward compatibility) and make None or False the setting for "disable pagination". Of course, this can also be implemented without breakting backwards compatibility, but list_per_page = None sounds odd.

I created a thread on this in the django-developers Google Group, to find a reasonable solution.

neforms-admin should make this easier; assigning to xian just in case he comes up with some template magic for it.

I'm working on a patch for this, basically, the same thing done in r14828, allow custom Paginators, but for the Admin app.

(Possibly there could be a "NullPaginator" class that always put everything on Page 1.)

Replying to kmike:

Isn't this issue fixed?


One could argue, that Django should also provide the "NullPaginator" class, but you're right that the main issue here is fixed in Django 1.3

It is still not trivial to turn off pagination. This makes ModelAdmin impossible to use on many large tables where select count(*) takes a long time (i.e. 1M+ records on InnoDB tables).

Ideally, there would be a NullPaginator available. A nice to have would be to have an option for a 'next and previous only' paginator that doesn't give page counts or estimates of the total number of records, just next and previous page links.

I've been looking at this today and there's quite a few places where the assumption that the paginator is dealing with a countable set is made. Making it work where you don't want to/can't count the number of items in the set means changing:

  1. the {% search %} admin tag
  2. the {% pagination %} admin tag
  3. the ChangeList class (in changelist_view method)
  4. the paginator to one that doesn't implement count, num_pages and page_range properties

1 & 2 can be fixed by overriding the change_list.html template to use alternative template tags (e.g. {% infinite_pagination %}). 3 requires deriving from ModelAdmin and cut'n'pasting the entire method. 4 is available here:

However this is really ugly and a lot of work for someone.

I think ideally the template tags and ChangeList class should be updated to not assume the ability to access the count, num_pages and page_range properties - ie have an "UncountedPaginator". Possibly this would be a base class of Paginator so you'd have NullPaginator (displays everything) -> UncountedPaginator -> Paginator.

comment:12 Changed 11 years ago by Adam Nelson

I strongly agree with boxm on this one. Counting the number of records is often most onerous for the very sets that need to be paginated. The UncountedPaginator is a great solution.

Patch that implements above idea on #8408 - this should enable a NullPaginator to work with admin

I believe this issue is fixed in 1.8 by the show_full_result_count option (ticket #8408 mentioned above).

Can everything else be handled by setting list_per_page to a very large number?

show_full_result_count does not fix the issue as paginator.count is still called:

comment:21 Changed 6 years ago by Sasha Gaevsky

It does fix the issue, since paginator.count return total number of objects -

Thus, I believe the ticket could be closed.
