Given a simple contact form:

# 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 

The view can be constructed using a FormView:

# 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(ContactView, self).form_valid(form) 

Notes:

Generic views really shine when working with models. These generic views will automatically create a ModelForm, so long as they can work out which model class to use:

Model form views provide a form_valid() implementation that saves the model automatically. You can override this if you have any special requirements; see below for examples.

You don't even need to provide a success_url for CreateView or UpdateView-they will use get_absolute_url() on the model object if available.

If you want to use a custom ModelForm (for instance to add extra validation) simply set form_class on your view.

First we need to add get_absolute_url() to our Author class:

# models.py 
 
from django.core.urlresolvers import reverse 
from django.db import models 
 
class Author(models.Model): 
    name = models.CharField(max_length=200) 
 
    def get_absolute_url(self): 
        return reverse('author-detail', kwargs={'pk': self.pk}) 

Then we can use CreateView and friends to do the actual work. Notice how we're just configuring the generic class-based views here; we don't have to write any logic ourselves:

# views.py 
 
from django.views.generic.edit import CreateView, UpdateView, DeleteView 
from django.core.urlresolvers import reverse_lazy 
from myapp.models import Author 
 
class AuthorCreate(CreateView): 
    model = Author 
    fields = ['name'] 
 
class AuthorUpdate(UpdateView): 
    model = Author 
    fields = ['name'] 
 
class AuthorDelete(DeleteView): 
    model = Author 
    success_url = reverse_lazy('author-list') 

We have to use reverse_lazy() here, not just reverse as the urls are not loaded when the file is imported.

The fields attribute works the same way as the fields attribute on the inner Meta class on ModelForm. Unless you define the form class in another way, the attribute is required and the view will raise an ImproperlyConfigured exception if it's not.

If you specify both the fields and form_class attributes, an ImproperlyConfigured exception will be raised.

Finally, we hook these new views into the URLconf:

# urls.py 
 
from django.conf.urls import url 
from myapp.views import AuthorCreate, AuthorUpdate, AuthorDelete 
 
urlpatterns = [ 
    # ... 
    url(r'author/add/$', AuthorCreate.as_view(), name='author_add'), 
    url(r'author/(?P<pk>[0-9]+)/$', AuthorUpdate.as_view(),   
        name='author_update'), 
    url(r'author/(?P<pk>[0-9]+)/delete/$', AuthorDelete.as_view(),  
        name='author_delete'), 
] 

In this example:

If you wish to have separate templates for CreateView and UpdateView, you can set either template_name or template_name_suffix on your view class.

To track the user that created an object using a CreateView, you can use a custom ModelForm to do this. First, add the foreign key relation to the model:

# models.py 
 
from django.contrib.auth.models import User 
from django.db import models 
 
class Author(models.Model): 
    name = models.CharField(max_length=200) 
    created_by = models.ForeignKey(User) 
 
    # ... 

In the view, ensure that you don't include created_by in the list of fields to edit, and override form_valid() to add the user:

# views.py 
 
from django.views.generic.edit import CreateView 
from myapp.models import Author 
 
class AuthorCreate(CreateView): 
    model = Author 
    fields = ['name'] 
 
    def form_valid(self, form): 
        form.instance.created_by = self.request.user 
        return super(AuthorCreate, self).form_valid(form) 

Note that you'll need to decorate this view using login_required(), or alternatively handle unauthorized users in the form_valid().

Here is a simple example showing how you might go about implementing a form that works for AJAX requests as well as normal form POST:

from django.http import JsonResponse 
from django.views.generic.edit import CreateView 
from myapp.models import Author 
 
class AjaxableResponseMixin(object): 
    def form_invalid(self, form): 
        response = super(AjaxableResponseMixin, self).form_invalid(form) 
        if self.request.is_ajax(): 
            return JsonResponse(form.errors, status=400) 
        else: 
            return response 
 
    def form_valid(self, form): 
        # We make sure to call the parent's form_valid() method because 
        # it might do some processing (in the case of CreateView, it will 
        # call form.save() for example). 
        response = super(AjaxableResponseMixin, self).form_valid(form) 
        if self.request.is_ajax(): 
            data = { 
                'pk': self.object.pk, 
            } 
            return JsonResponse(data) 
        else: 
            return response 
 
class AuthorCreate(AjaxableResponseMixin, CreateView): 
    model = Author 
    fields = ['name']
