Django is a powerful web framework for building web applications quickly and efficiently. It includes many built-in views that can be used to handle common tasks such as displaying a list of objects, creating new objects, and editing existing objects. In this answer, I will cover 10 Django built-in views that you should know for your next project, along with proper explanations and examples.
ListView
ListView The ListView is a built-in view that displays a list of objects from a model. It is commonly used to display a list of blog posts, products, or other types of content. Here's an example:
from django.views.generic import ListView
from .models import Post
class PostListView(ListView):
model = Post
template_name = 'blog/post_list.html'
context_object_name = 'posts'
ordering = ['-date_posted']
In this example, the ListView is used to display a list of blog posts from the Post model. The template_name attribute specifies the template to use for rendering the view, and the context_object_name attribute specifies the name of the context variable that will contain the list of objects.
DetailView
DetailView The DetailView is a built-in view that displays the details of a single object from a model. It is commonly used to display a blog post, product details, or other types of content. Here's an example:
from django.views.generic import DetailView
from .models import Post
class PostDetailView(DetailView):
model = Post
template_name = 'blog/post_detail.html'
context_object_name = 'post'
In this example, DetailView is used to display the details of a single blog post from the Post model. The template_name attribute specifies the template to use for rendering the view, and the context_object_name attribute specifies the name of the context variable that will contain the object.
CreateView
CreateView The CreateView is a built-in view that displays a form to create a new object from a model. It is commonly used to create new blog posts, products, or other types of content. Here's an example:
from django.views.generic import CreateView
from .models import Post
from .forms import PostForm
class PostCreateView(CreateView):
model = Post
form_class = PostForm
template_name = 'blog/post_form.html'
In this example, the CreateView is used to display a form to create a new blog post from the Post model. The form_class attribute specifies the form to use for rendering the form, and the template_name attribute specifies the template to use for rendering the view.
UpdateView
UpdateView The UpdateView is a built-in view that displays a form to edit an existing object from a model. It is commonly used to edit blog posts, products, or other types of content. Here's an example:
from django.views.generic import UpdateView
from .models import Post
from .forms import PostForm
class PostUpdateView(UpdateView):
model = Post
form_class = PostForm
template_name = 'blog/post_form.html'
In this example, the UpdateView is used to display a form to edit an existing blog post from the Post model. The form_class attribute specifies the form to use for rendering the form, and the template_name attribute specifies the template to use for rendering the view.
DeleteView
DeleteView The DeleteView is a built-in view that displays a confirmation page before deleting an object from a model. It is commonly used to delete blog posts, products, or other types of content. Here's an example:
from django.views.generic import DeleteView
from .models import Post
from django.urls import reverse_lazy
class PostDeleteView(DeleteView):
model = Post
template_name = 'blog/post_confirm_delete.html'
success_url = reverse_lazy('blog-home')
In this example, the DeleteView is used to display a confirmation page before deleting a blog post from the Post model. The template_name attribute specifies the template to use for rendering the view, and the success_url attribute specifies the URL to redirect to after the object is deleted.
FormView
FormView The FormView is a built-in view that displays a form and processes user input. It can be used to implement custom forms or handle form submissions. Here's an example:
from django.views.generic import FormView
from .forms import ContactForm
from django.urls import reverse_lazy
class ContactView(FormView):
form_class = ContactForm
template_name = 'contact.html'
success_url = reverse_lazy('contact-success')
def form_valid(self, form):
form.send_email()
return super().form_valid(form)
In this example, the FormView is used to display a contact form and send an email when the form is submitted. The form_class attribute specifies the form to use for rendering the form, and the template_name attribute specifies the template to use for rendering the view. The success_url attribute specifies the URL to redirect to after the form is successfully submitted. The form_valid() method is overridden to send the email when the form is submitted.
