Need urgent help with filter system (django-filter) in Django

[Aritra Ray]

Hi,

I've been trying to introduce a filter system in my Django-ecommerce website and I've been struggling despite reading the documents, etc. I am using 'django-filter' and below are filters.py, models.py, views.py and the template. To check out the project, follow the github link: https://github.com/First-project-01/Django-ecommerce.

Will be grateful if anyone can sort this out. Thanks in advance.

Regards,

Aritra

#filters.py

class ProductFilter(django_filters.FilterSet):

    price = django_filters.NumberFilter()

    price__gt = django_filters.NumberFilter(field_name='price', lookup_expr='gt')

    price__lt = django_filters.NumberFilter(field_name='price', lookup_expr='lt')

    class Meta:

        model = Items

        fields = ['size', 'availability']

#views.py

class Product(ListView):

    model = Items

    paginate_by = 6

    template_name = 'products.html'

    def get_context_data(self, **kwargs):

        context = super(Product, self).get_context_data(**kwargs)

        context['filter'] = ProductFilter(self.request.GET, queryset=self.get_queryset())

        return context

#models.py

AVAILABILITY = (

    ('Y', 'Available'),

    ('N', 'Out of Stock'),

)

SIZES = (

    ('K', 'King - 108 x 120'),

    ('Q', 'Queen - 90 x 108')

)

class Items(BaseModel):

    title = models.CharField(max_length=100, null=True, blank=True)

    price = models.FloatField(null=True, blank=True)

    size = models.CharField(choices=SIZES, default=SIZES[0][0], max_length=1)

    description = models.TextField(max_length=500)

    availability = models.CharField(choices=AVAILABILITY, default=AVAILABILITY[0][0], max_length=1)

...

#product-list.html

<div class="col-md-3">

         <form method="get">

            {{ filter.form| crispy }}

            <button type="submit">Search</button>

         </form>

    </div>

This isn't working. When we are supplying a filter, the html is displaying all the products irrespective of the requested.

Sorry, it's not working. I tried items_filter.form but it didn't work. Kindly check my views.py if that'll be of any help or require any changes.

Okay.
If you using the Django filter then, please try like below in your views..

abc_list = ModelName.objects.all()

result_filter = ModelNameFilter(request.GET, queryset=abc_list)

Thanks & Regards

Can you write the class based function of the above views.py. I'm unable to do so. Will be of great help.
