The following views are described on this page and provide a foundation for editing content:

The messages framework contains
SuccessMessageMixin
, which
facilitates presenting messages about successful form submissions.
Note
Some of the examples on this page assume that an Author
model has been
defined as follows in myapp/models.py
:
from django.db import models
from django.urls import reverse
class Author(models.Model):
name = models.CharField(max_length=200)
def get_absolute_url(self):
return reverse('author-detail', kwargs={'pk': self.pk})
FormView
¶A view that displays a form. On error, redisplays the form with validation errors; on success, redirects to a new URL.
Ancestors (MRO)
This view inherits methods and attributes from the following views:
django.views.generic.edit.BaseFormView
Example myapp/forms.py:
from django import forms
class ContactForm(forms.Form):
name = forms.CharField()
message = forms.CharField(widget=forms.Textarea)
def send_email(self):
# send email using the self.cleaned_data dictionary
pass
Example myapp/views.py:
from myapp.forms import ContactForm
from django.views.generic.edit import FormView
class ContactView(FormView):
template_name = 'contact.html'
form_class = ContactForm
success_url = '/thanks/'
def form_valid(self, form):
# This method is called when valid form data has been POSTed.
# It should return an HttpResponse.
form.send_email()
return super().form_valid(form)
Example myapp/contact.html:
<form method="post">{% csrf_token %}
{{ form.as_p }}
<input type="submit" value="Send message">
</form>
CreateView
¶A view that displays a form for creating an object, redisplaying the form with validation errors (if there are any) and saving the object.
Ancestors (MRO)
This view inherits methods and attributes from the following views:
django.views.generic.detail.SingleObjectTemplateResponseMixin
django.views.generic.edit.BaseCreateView
Attributes
The CreateView
page displayed to a GET
request uses a
template_name_suffix
of '_form'
. For
example, changing this attribute to '_create_form'
for a view
creating objects for the example Author
model would cause the
default template_name
to be 'myapp/author_create_form.html'
.
When using CreateView
you have access to self.object
, which is
the object being created. If the object hasn’t been created yet, the
value will be None
.
Example myapp/views.py:
from django.views.generic.edit import CreateView
from myapp.models import Author
class AuthorCreate(CreateView):
model = Author
fields = ['name']
Example myapp/author_form.html:
<form method="post">{% csrf_token %}
{{ form.as_p }}
<input type="submit" value="Save">
</form>
UpdateView
¶A view that displays a form for editing an existing object, redisplaying the form with validation errors (if there are any) and saving changes to the object. This uses a form automatically generated from the object’s model class (unless a form class is manually specified).
Ancestors (MRO)
This view inherits methods and attributes from the following views:
django.views.generic.detail.SingleObjectTemplateResponseMixin
django.views.generic.edit.BaseUpdateView
Attributes
The UpdateView
page displayed to a GET
request uses a
template_name_suffix
of '_form'
. For
example, changing this attribute to '_update_form'
for a view
updating objects for the example Author
model would cause the
default template_name
to be 'myapp/author_update_form.html'
.
When using UpdateView
you have access to self.object
, which is
the object being updated.
Example myapp/views.py:
from django.views.generic.edit import UpdateView
from myapp.models import Author
class AuthorUpdate(UpdateView):
model = Author
fields = ['name']
template_name_suffix = '_update_form'
Example myapp/author_update_form.html:
<form method="post">{% csrf_token %}
{{ form.as_p }}
<input type="submit" value="Update">
</form>
DeleteView
¶A view that displays a confirmation page and deletes an existing object.
The given object will only be deleted if the request method is POST
. If
this view is fetched via GET
, it will display a confirmation page that
should contain a form that POSTs to the same URL.
Ancestors (MRO)
This view inherits methods and attributes from the following views:
django.views.generic.detail.SingleObjectTemplateResponseMixin
django.views.generic.edit.BaseDeleteView
django.views.generic.detail.BaseDetailView
Attributes
The DeleteView
page displayed to a GET
request uses a
template_name_suffix
of '_confirm_delete'
. For
example, changing this attribute to '_check_delete'
for a view
deleting objects for the example Author
model would cause the
default template_name
to be 'myapp/author_check_delete.html'
.
Example myapp/views.py:
from django.urls import reverse_lazy
from django.views.generic.edit import DeleteView
from myapp.models import Author
class AuthorDelete(DeleteView):
model = Author
success_url = reverse_lazy('author-list')
Example myapp/author_confirm_delete.html:
<form method="post">{% csrf_token %}
<p>Are you sure you want to delete "{{ object }}"?</p>
<input type="submit" value="Confirm">
</form>
