Re: m2m admin relationship selector with filter_horizontal and large datasets
Thanks Collin, I looked at raw field ids, but feels too basic. I'm attempting to implement autocomplete_light which seems to offer m2m selection. IT would seem that this would be a common problem: select from a large list without displaying that entire list. filter_horizontal would work if I could turn off the left hand side list and still get the search and select functions. I wish I had time to extend that.

m2m admin relationship selector with filter_horizontal and large datasets
I have a Category model that is m2m with an Article model and need to make categories selectable in my article admin. So I'm using a filter_horizontal and the problem is that I have thousands of categories and do not want to load them all into the left hand side (lhs) of filter_horizontal. Is there a way to limit the lhs to just a search functionality instead of a category browse? Is there another widget I should use just for searching categories to make m2m relationships?

Re: Return to paginated ListView page after update
There's probably better solution, but this works:
1) added a page_number to the view
2) subclass dispatch and in get page from request: self.page_number
= request.REQUEST['page']
3) subclass get_context_data and put the page number in a hidden files on
the form: context['hidden_field'] = self.page_number #20
in the form:
{% for hidden_field in form.hidden_fields %}
{{ hidden_field }}
{% endfor %}
4) subclass form_valid and set the page_number: self.page_number =
context['hidden_field']
5) and finally:
get_success_url(self, **kwargs):
return reverse('articleeditor_list', kwargs={'page':
self.page_number})
class ArticleEditView(UpdateView):
model = Article
template_name = 'edit_template.html'
page_number = 1
def dispatch(self, request, *args, **kwargs):
self.page_number = request.REQUEST['page']
return super(ArticleEditView, self).dispatch(request, *args,
**kwargs)
def get_context_data(self, **kwargs):
context = super(ArticleEditView, self).get_context_data(**kwargs)
context['hidden_field'] = self.page_number
return context
def form_valid(self, form, **kwargs):
context = self.get_context_data(**kwargs)
self.page_number = context['hidden_field']
return super(ArticleEditView, self).form_valid(form)
def get_success_url(self, **kwargs):
return reverse('editor_listview', kwargs={'page': self.page_number})

Return to paginated ListView page after update
It must be more simple than the nothingness that searching google is
showing me... how can I to get back to the last page (say page
2: http://127.0.0.1:8000/articlelist/2, which works) in a ListView after an
UpdateView.
I can go to a random page - 10 in the below UpdateView - but how do I
capture the referring ListView's current page and then feed that back in
get_success_url after the update?
class ArticleEditView(UpdateView):
model = Article
template_name = 'edit_template.html'
form_class = ArticleForm
def get_success_url(self):
return reverse('editor_listview', kwargs={'page': 10})
Thank you
