I have my search working the way I need it to for the most part, but I would like to be able to sort based on the categories a user selects.
I have sub-classed searchForm to contain:
def no_query_found(self):
"""
Determines the behavior when no query was found.
By default, no results are returned (``EmptySearchQuerySet``).
Should you want to show all results, override this method in your
own ``SearchForm`` subclass and do ``return self.searchqueryset.all()``.
"""
return self.searchqueryset.models(Idea)
def search(self):
sqs = super(IdeaCategories, self).search()
if not self.is_valid():
return self.no_query_found()
if self.cleaned_data['category']:
sqs = sqs.filter(tags__contains=self.cleaned_data['category'])
return sqs
The following works as expected:
/testing/search/?q=test -> All results related to "test"
/testing/search/?category=Development&q= -> All results related to "development"
/testing/search/?category=Development&q=book -> All results related to "development" and containing "book"
The only thing I can't figure out is how to get it to search correctly on the categories of 2 or more:
/testing/search/?category=Development&category=Supplemental+Material&q=
Is there a way to get a list of categories, query and filter for combined results? Such as:
sqs = sqs.filter(tags__contains["Development", "Supplemental Material"])
Okay! So I got this figured out now.
Inside my searchForm class:
I created a list of choices from the database to use in a form.
choices_group = tuple(
[(choice, choice) for choice in
Category.objects.values_list('label', flat=True)])
Apply these choices to my form.
sort = forms.MultipleChoiceField(choices=choices_group, widget=forms.CheckboxSelectMultiple)
Created my query set.
q_sorted = self.cleaned_data['sort']
if q_sorted:
sqs = sqs.filter(tags__in=q_sorted)
Finally, in my template.
{{form.sort}}
