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

class django.views.generic.edit.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.base.TemplateResponseMixin
• django.views.generic.edit.BaseFormView
• django.views.generic.edit.FormMixin
• django.views.generic.edit.ProcessFormView
• django.views.generic.base.View

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 ContactFormView(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>

class django.views.generic.edit.BaseFormView

A base view for displaying a form. It is not intended to be used directly, but rather as a parent class of the django.views.generic.edit.FormView or other views displaying a form.

Ancestors (MRO)

This view inherits methods and attributes from the following views:

• django.views.generic.edit.FormMixin
• django.views.generic.edit.ProcessFormView

CreateView

class django.views.generic.edit.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.base.TemplateResponseMixin

Attributes

• template_name_suffix

  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'.

• object

  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 AuthorCreateView(CreateView):
    model = Author
    fields = ["name"]

Example myapp/author_form.html:

<form method="post">{% csrf_token %}
    {{ form.as_p }}
    <input type="submit" value="Save">
</form>

class django.views.generic.edit.BaseCreateView

Ancestors (MRO)

This view inherits methods and attributes from the following views:

• django.views.generic.edit.ModelFormMixin
• django.views.generic.edit.ProcessFormView

UpdateView

class django.views.generic.edit.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:

• object

  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

DeleteView

class django.views.generic.edit.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.

• template_name_suffix

  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'.

from django.urls import reverse_lazy
from django.views.generic.edit import DeleteView
from myapp.models import Author
class AuthorDeleteView(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>
    {{ form }}
    <input type="submit" value="Confirm">
