Summary<\/strong>: in this tutorial, you’ll learn how to use the Django CreateView<\/code> class to define a class-based view that creates a task for the Todo application.<\/p>\n\n\n\n

This tutorial begins where the Django DetailView tutorial<\/a> left off.<\/p>\n\n\n\n

Defining the CreateView class #<\/a><\/h2>\n\n\n\n

The CreateView<\/code> class allows you to create a class-based view that displays a form for creating an object, redisplaying the form with validation errors, and saving the object into the database.<\/p>\n\n\n\n

To use the CreateView<\/code> class, you define a class that inherits from it<\/a> and add some attributes and methods.<\/p>\n\n\n\n

For example, the following uses the CreateView<\/code> class to define a class-based view that renders a form for creating a new task in the Todo app<\/a>:<\/p>\n\n\n

# ..<\/span>\nfrom<\/span> django.views.generic.edit import<\/span> CreateView\nfrom<\/span> django.contrib import<\/span> messages\nfrom<\/span> django.urls import<\/span> reverse_lazy\nfrom<\/span> .models import<\/span> Task\n\nclass<\/span> TaskCreate<\/span>(CreateView)<\/span>:<\/span>\n    model = Task\n    fields = ['title'<\/span>,'description'<\/span>,'completed'<\/span>]\n    success_url = reverse_lazy('tasks'<\/span>)\n    \n   \n    def<\/span> form_valid<\/span>(self, form)<\/span>:<\/span>\n        form.instance.user = self.request.user\n        messages.success(self.request, \"The task was created successfully.\"<\/span>)\n        return<\/span> super(TaskCreate,self).form_valid(form)\n\n# other classes & functions<\/span><\/code><\/span>Code language:<\/span> Python<\/span> (<\/span>python<\/span>)<\/span><\/small><\/pre>\n\n\n
How it works:<\/p>\n\n\n\n
First, import the CreateView<\/code> class, the reverse_lazy()<\/code> function, and messages<\/code> module.<\/p>\n\n\n\n
Second, define the TaskCreate<\/code> class that inherits from the CreateView<\/code> class. In the CreateView<\/code> class, we define the following attributes and methods:<\/p>\n\n\n\n
