Summary<\/strong>: in this tutorial, you’ll learn how to use the Django DeleteView<\/code> class to define a class-based view that deletes an existing object.<\/p>\n\n\n\n

This tutorial begins where\u00a0the\u00a0Django UpdateView tutorial<\/a>\u00a0left off.<\/p>\n\n\n\n

Create a Django DeleteView class #<\/a><\/h2>\n\n\n\n

The Django DeleteView<\/code> class allows you to define a class-based view that displays a confirmation page and deletes an existing object.<\/p>\n\n\n\n

If the HTTP request method is GET<\/code>, the DeleteView<\/code><\/code> view will display the confirmation page. However, if the request is POST<\/code>, the DeleteView<\/code><\/code> view will delete the object.<\/p>\n\n\n\n

To use the DeleteView<\/code> class, you define a class that inherits<\/a> from it and add attributes<\/a> and methods<\/a> to override the default behaviors.<\/p>\n\n\n\n

For example, the following defines a TaskDelete<\/code> class that deletes a task for the Todo app<\/a>:<\/p>\n\n\n

#...<\/span>\nfrom<\/span> django.views.generic.edit import<\/span> DeleteView, CreateView, UpdateView\nfrom<\/span> django.contrib import<\/span> messages\nfrom<\/span> django.urls import<\/span> reverse_lazy\n\nfrom<\/span> .models import<\/span> Task\n\nclass<\/span> TaskDelete<\/span>(DeleteView)<\/span>:<\/span>\n    model = Task\n    context_object_name = 'task'<\/span>\n    success_url = reverse_lazy('tasks'<\/span>)\n    \n    def<\/span> form_valid<\/span>(self, form)<\/span>:<\/span>\n        messages.success(self.request, \"The task was deleted successfully.\"<\/span>)\n        return<\/span> super(TaskDelete,self).form_valid(form)\n\n#...<\/span><\/code><\/span>Code language:<\/span> Python<\/span> (<\/span>python<\/span>)<\/span><\/small><\/pre>\n\n\n
In this example, we define the TaskDelete<\/code><\/code> class that is a subclass of the DeleteView<\/code> class. The TaskDelete<\/code><\/code> class has the following attributes:<\/p>\n\n\n\n
