        Django Admin Autocomplete Filter
        ================================
        A simple Django app to render list filters in django admin using autocomplete widget. This app is heavily inspired from [dal-admin-filters.](https://github.com/shamanu4/dal_admin_filters)
        
        Overview:
        ---------
        
        Django comes preshipped with an admin panel which is a great utility to create quick CRUD's.
        The django 2.0 came with much needed [autocomplete_fields](https://docs.djangoproject.com/en/2.1/ref/contrib/admin/#django.contrib.admin.ModelAdmin.autocomplete_fields "autocomplete_fields") which uses select2 widget that comes with a search feature that loads the options asynchronously.
        We can use this in django admin list filter.
        
            
        
        Requirements:
        -----------
        Requires Django version >= 2.0
        
        Installation:
        ------------
        You can install it via pip or to get the latest version clone this repo.
        
        `
        pip install django-admin-autocomplete-filter-faisal
        `
        
        Add ``admin_auto_filters`` to your ``INSTALLED_APPS`` inside settings.py of your project.
        
        Usage:
        -----
        Let's say we have following models:
        ``` python
        class Artist(models.Model):
            name = models.CharField(max_length=128)
        
        class Album(models.Model):
            name = models.CharField(max_length=64)
            artist = models.ForeignKey(Artist, on_delete=models.CASCADE)
            cover = models.CharField(max_length=256, null=True, default=None)
        ```
        And you would like to filter results in Album Admin on the basis of artist, then you can define `search fields` in Artist and then define filter as:
        
        ``` python
        from admin_auto_filters.filters import AutocompleteFilter
        
        class ArtistFilter(AutocompleteFilter):
            title = 'Artist' # display title
            field_name = 'artist' # name of the foreign key field
        
        class ArtistAdmin(admin.ModelAdmin):
            search_fields = ['name'] # this is required for django's autocomplete functionality
        	...
        
        class AlbumAdmin(admin.ModelAdmin):
            list_filter = [ArtistFilter]
            
            '''
               defining this class is required for AutocompleteFilter
               it's a bug and I am working on it.
            '''
            class Media:
                pass
        	...
        ```
        
        After following these steps you may see the filter as:
        
        ![](https://raw.githubusercontent.com/farhan0581/django-admin-autocomplete-filter/master/admin_auto_filters/media/screenshot1.png)
        
        ![](https://raw.githubusercontent.com/farhan0581/django-admin-autocomplete-filter/master/admin_auto_filters/media/screenshot2.png)
        
        
        Now you can also register your custom view instead of using django admin's search_results to control the results in the autocomplete. For this you will need to create your custom view and register the url in your admin class as shown below:
        
        In your views.py:
        
        ```python
        from admin_auto_filters.views import AutocompleteJsonView
        
        class CustomSearchView(AutocompleteJsonView):
            def get_queryset(self):
            '''
               your custom logic goes here.
            '''
                queryset = Artist.objects.all().order_by('name')
                return queryset
        ```
        
        After this, register this view in your admin class as:
        
        ```python
        
        class AlbumAdmin(admin.ModelAdmin):
            list_filter = [ArtistFilter]
        
            class Media:
                pass
            
            def get_urls(self):
                urls = super().get_urls()
                custom_urls = [
                    path('custom_search/', self.admin_site.admin_view(CustomSearchView.as_view(model_admin=self)),
                         name='custom_search'),
                ]
                return custom_urls + urls
        ```
        
        Finally just tell the filter class to use this new view as:
        
        ```python
        class ArtistFilter(AutocompleteFilter):
            title = 'Artist'
            field_name = 'artist'
        
            def get_autocomplete_url(self, request, model_admin):
                return reverse('admin:custom_search')
        ```
