How can the pagination feature be implemented in Django?

In Django, we can use the built-in Paginator to implement pagination. Here are the general steps to implement pagination.

1. Retrieve the dataset that needs to be paginated in the view function.
2. Create a Paginator object by passing in the dataset and the number of items to display per page.
3. Retrieve data for a specific page using the page method of the Paginator object.
4. Use Django template tags and filters in the template to display pagination links and the data of the current page.

Here is a simple example code demonstrating how to implement pagination in Django view functions.

from django.core.paginator import Paginator
from django.shortcuts import render
from .models import MyModel

def my_view(request):
    data_list = MyModel.objects.all()
    
    paginator = Paginator(data_list, 10)  # 每页显示10条数据
    page_number = request.GET.get('page')
    page_obj = paginator.get_page(page_number)
    
    return render(request, 'my_template.html', {'page_obj': page_obj})

In the code above, we start by retrieving all the data collection data_list from the database. Then, we create a Paginator object and pass the data collection and the number of items to display per page to the Paginator object. Next, we extract the page number parameter from the request, and then use the Paginator object’s get_page method to fetch the data for the specified page. Finally, we pass the paginated data to the template for display.

In the template, you can utilize the page_obj object to access pagination data, such as page_obj.object_list to retrieve the current page’s data list, and page_obj.has_next to determine if there is a next page. You can display pagination links and the current page’s data using Django template tags and filters, with more details available in the Django official documentation on Paginator.
