In this video, we'll learn about the very useful Django Filter package, which allows you to extract filtering logic for your querysets into dedicated classes, called FilterSets.
We'll go over an example of filtering a list of books, using a FilterSet, and will demonstrate how to use Django-Filter with functional and class-based views.
We'll also demonstrate django-filter integration with Django REST Framework.

How to style the dropdown filter to bootstraps class (or any class) e.g. model-form. Some use Crispy Forms but it would be good to have a way to add a html class. For forms it's straight forward but for the filter generated fields+buttons I haven't manage to do it. Any tips/advice? Great video thanks for posting keep it up.

Grate video! Let's say you want a COUNT value in the bottom of the table (or other cases you might want SUM for other purposes). Is that possible while using django-filters or is there another way to implement that with the features that comes with django-filters? I've been reading through the docs but can't seem to find a way while using django-filters. Thanks for a great channel :)
@maathias9
@maathias9 3 месяца назад
Found solution (example) If anyone else needed: In views .py - book_filter = BookFilter(request.GET, queryset=Book.objects.all()) books = book_filter.qs # Count of the books book_count = books.count() -- Include book_count in the context, then in your template include {{book_count}} where needed (maybe create a new from your table)

Well presented and easy to understand. I've noticed all the videos on using Django-Filter uses objects.all() to display all database records on the page on render. What if there are 1000s of records that you don't want all rendered, but only the subset displayed after filtering?
@bugbytes3923
@bugbytes3923 Год назад
Thank you Michael. To display a subset, you can use Django Pagination utilities to page the queryset that's returned after the filtering. Could fire up a quick video on this topic, if you'd like.

@@bugbytes3923 Thank you for the quick response. I actually figured it out about an hour after asking. I'm using Django-Filters and checking the dictionary if any filters are populated. If yes, display the filtered rows. If no, display nothing. So far seems to be working

When you initially load the page, all the books gets displayed in the template. But how would you manage to have the table empty when you load the page? And only fetch the books when you filter? And if the "name" filter is empty and you click search, it then would search the entire db and fetch all the books? Thanks for your work and channel 🙏🏻
@bugbytes3923
@bugbytes3923 Месяц назад
Thanks for the comment! Will try and answer. For an initially empty table, you can load no books initally with: Book.objects.none() as the queryset. When you apply the filter, you can pass the params to the Book.objects.filter() function. You can prevent submitting the form with an empty name filter by adding a minimum length to the field. developer.mozilla.org/en-US/docs/Web/HTML/Attributes/minlength Note: a full-table scan over all books will occur no matter what you search for (empty string, or a certain text) unless you have an index on the Book's "name" field. Adding an index would allow much more efficient filtering over a large table.

@billcooper8625 4 месяца назад
Would this work with fk? For instance, say you have a class table,student table, & student grades table in the db. In the view, you display students in a table but then with Django-filter could you apply filtering back to the grades for each student to filter the table in the view based on students with certain grades? For instance, show me student in class A and B with Grades of b or higher….

Thank you! Can you please explain why adding a content field inside of Meta class doesn't work, but adding it above does? This: import django_filters from .models import UserQuestionForLesson class QuestionsFilter(django_filters.FilterSet): content = django_filters.CharFilter(lookup_expr='icontains') class Meta: model = UserQuestionForLesson fields = [ 'is_answered', ] It is just an ordinary CharField where user types in a question for a lesson.
@bugbytes3923
@bugbytes3923 10 месяцев назад
Hi Tomislav. The content field you've defined should also work if added to the "fields" list in the Meta class (as longs as it exists as a field on your model). Does that not work? One caveat: for a CharFilter, I believe the default lookup is "exact", so there would have to be an exact match between the submitted content, and what's stored in the database for the "content" field
@TomislavMiletic
@TomislavMiletic 10 месяцев назад
@@bugbytes3923 that was fast, thank you. Okay so adding a content field into Meta class doesn't work. Yes, there is a "content" charfield in the Question module, and it works if being added above the Meta class, and i used icontains, it is working. Just wanted to ask because i followed the tutorial and didn't understand why it is not working.
@bugbytes3923
@bugbytes3923 10 месяцев назад
@@TomislavMiletic I think because the default lookup is “exact”, that may be why it doesn’t work when it’s only added to Meta.fields? It works above because you override the default and use “icontains” - maybe this is the issue?

@@TomislavMiletic If you want to keep the field in Meta, you can use the second of the two approaches (classes) in the code block at this link: django-filter.readthedocs.io/en/stable/ref/filterset.html#declaring-filterable-fields You can specify not only the field, but also the lookup, directly in the Meta class. Just use a dictionary, rather than a list, with dictionary values being the lookup for that field.
