Django Filtering System with django-filter - Filter Queryset (2018)

In this tutorial you will learn how to implement a filtering system with django using the django-filter package.
7 Tips For Getting Better At Django:
mailchi.mp/dea...
Starting point for this tutorial:
github.com/Rec...
First, we will enable filtering using a model's fields, and afterwards we will implement our own custom field for changing the ordering of our queryset.
You will be installing the package using 'pip install django-filter'.
Afterwards, you will learn how to create a FilterSet and specify the fields to use in our form inside of the Meta class. Then, we will create a new SnippetFilter instance and pass it to our context.
In our template, we will use filter.qs to loop over the queryset.

quick addition: if you don't need to do anything fancy in your view, you can save yourself time by using the generic FilterView class inside of django_filters.views!

how would you implement pagination with django-filter?, because pagination_by attribute of ListView not working

@@Karenms92 it should be paginate_by, not pagination_by :)

Thank you very much !! But could you please tell me how to customize the queryset url ? How to hide the non used filters from the url ? When I’m not searching in body in the url we get example.com/?title=x&body=

@the dumbfounds how can I connect filter-pagination-order with django-filter only on classes" listviews-filterset- with filter dates greater than and lower than of field with dates and with widged to select d-m-y. Can you help with that ?

how to change default django admin theme ? any video or some tutorial to do it ?

[@MartinOru]

Just what i have been looking for. How would you implement pagination for CBV with django-filter

[@thedumbfounds767]

@@MartinOru there is a generic FilterView. However, I don't know if it has the paginate_by attribute. If it doesn't, you can use a ListView with the paginate_by attribute, and just implement the filtering manually.

[@niteshrawat576]

Hey man, can you explain further on how to mimic filterset with manual filtering so that i can apply pagination to it (thats my real goal). I am just real bad on this one.

[@modhaffermodhaffer]

@@thedumbfounds767 I am facing the same problem. Cannot get proper pagination. It lists the found results, then starts listing all the objects of the model. If it is possible to give an example of pagination, we would be very grateful.

[@chromebook2447]

If i had a multiple name fields in my database(ex. First Name & Last Name), how would i be able to make both fields searchable from one search bar instead of having 2 separate search fields on the page? Would you happen to know or be able to point me to the appropriate documentation? Great video btw!

is there a way to render a just specific field?

[@elonarbiture5691]

I got this working but I'm curious how you could easily keep the full list from appearing until after you filter the results? In other words, don't display anything until you actually apply the filter? Thank you.

[@franciscovinuesa7908]

last part not working ! somehow it shows always the same query not changing by ascending or descending filters

[@ЕвгенийМарьянов-й8р]

CSS don't work, because there is no static directory in your github repo) Thanks for you video!

[@guillermoreyes5495]

This way the view is returning 2 querysets, one filtered by SnippetFilter and another generated by the default get_queryset method of ListView. I think you should overwrite the get_queryset method or use FilterView as mentioned below. Thank you.

[@viswanathanl215]

Hi. Thanks for the video. I have a doubt. How to add calender for date wise filter in admin sidebar?

This tutorial saved my life! Or at the very least, a day or two of doing this manually at my job. It is possible to use django-filters with Ajax so we don't have to reload the page?

[@thedumbfounds767]

Sure, I guess you could use javascript to construct the parameters list based on the values that were entered into the input fields of a form. Then, you could send an AJAX request to your ajax view url and append the GET parameters string you previously constructed using javascript. In the view, you can use the filter just like shown in the video. That view would need to return a serialized version of the objects, which is fairly easy to do, even without using the DRF. Take a look at this for serialization: docs.djangoproject.com/en/2.0/topics/serialization/#serializing-data

[@adam_balkoev]

Is it possible to automatically refresh the page when you select a filter, can you give an example? Thanks for video, like!

I'm very late to the party but I want to filter without touching the template. Is there a way to do this?

[@boryskuczkowski]

What would be an elegant way of searching through both title and body using one search field?

[@thedumbfounds767]

Don't know if django-filter has that functionality built-in. For a custom solution, you can use Q objects. Something like this (untested): Snippet.objects.filter(Q(title__icontains=searchterm) | Q(body__icontains=searchterm)) Does that help?

[@boryskuczkowski]

@@thedumbfounds767 yep, I worked it out almost the same way, no need to use django-filter at all, just import q from django.db. Thanks for your answer!

[@czanki]

I am new to python and django. I am trying to filter List by date range set by web user (from, to). To be honest I thought it is kinda obvious thing to do, but I have real hard time to find any solution for that. In addition I want to use tempusdominus so users would be able to put dates in friendly looking way. Maybe making a video on how to filter queryset by dates provided by user would be a good idea for others also? Thank you for this video, it helped mi a lot with making search field!
