django-filter use paginations

django-filter is a powerful library for creating filters in Django applications. When you want to use pagination with django-filter, you typically combine it with Django's built-in pagination classes. Here's how you can use django-filter along with pagination in your Django project:

  1. Install django-filter and Configure Your Filter: If you haven't already, install the django-filter library using pip:

    pip install django-filter

    Then, define your filter using django-filter as you normally would.

  2. Configure Pagination: In your view or API endpoint, configure pagination using Django's built-in pagination classes, such as Paginator and Page. Here's a basic example using Django's generic views:

    from django.core.paginator import Paginator, Page from django.shortcuts import render from django_filters.views import FilterView from .models import YourModel from .filters import YourModelFilter class YourModelListView(FilterView): model = YourModel template_name = 'your_model_list.html' filterset_class = YourModelFilter paginate_by = 10 # Number of items per page def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) paginator = Paginator(self.object_list, self.paginate_by) page_number = self.request.GET.get('page') page = paginator.get_page(page_number) context['page'] = page return context

  3. Create the Template: In your template (your_model_list.html in this example), loop through the paginated objects and render the desired information. Use the pagination objects provided by the context, such as page:

    {% extends 'base.html' %} {% block content %} <h1>Your Model List</h1> <ul> {% for item in page %} <li>{{ item }}</li> {% endfor %} </ul> <div class="pagination"> <span class="step-links"> {% if page.has_previous %} <a href="?page=1">&laquo; first</a> <a href="?page={{ page.previous_page_number }}">previous</a> {% endif %} <span class="current"> Page {{ page.number }} of {{ page.paginator.num_pages }}. </span> {% if page.has_next %} <a href="?page={{ page.next_page_number }}">next</a> <a href="?page={{ page.paginator.num_pages }}">last &raquo;</a> {% endif %} </span> </div> {% endblock %}

In this example, YourModelListView is a subclass of FilterView from django-filter. It uses Django's pagination to display the filtered results with pagination controls. The template your_model_list.html renders the paginated objects and includes pagination links.

Remember to replace YourModel and YourModelFilter with your actual model and filter class. This example demonstrates a basic implementation, and you can customize the pagination style and template as needed.
