本页中描述的以下视图提供内容编辑的基础功能：
注
本页中的一些示例假定Author 模型已经在myapp/models.py 中定义如下：
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})
显示表单的视图。发送错误时，重新显示表单和验证的错误；成功时，重定向到一个新的URL。

该视图从以下视图继承方法和属性：
示例 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
示例 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(ContactView, self).form_valid(form)
示例 myapp/contact.html：
<form action="" method="post">{% csrf_token %}
{{ form.as_p }}
<input type="submit" value="Send message" />
</form>
一个视图，它显示一个表单用于创建对象，出现错误时会重新显示表单，否则保存该对象。

该视图从以下视图继承方法和属性：
属性
显示给GET请求的CreateView页使用'_ form'的template_name_suffix。例如，对于为示例Author模型创建对象的视图，将此属性更改为'_ create_form'会导致默认template_name为'myapp/author_create_form.html'。
使用CreateView时，您可以访问self.object，这是正在被创建的对象。如果对象尚未创建，则值将为None。
示例 myapp/views.py：
from django.views.generic.edit import CreateView
from myapp.models import Author
class AuthorCreate(CreateView):
model = Author
fields = ['name']
示例 myapp/author_form.html：
<form action="" method="post">{% csrf_token %}
{{ form.as_p }}
<input type="submit" value="Create" />
</form>
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).

该视图从以下视图继承方法和属性：
属性
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.
示例 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'
示例 myapp/author_update_form.html：
<form action="" method="post">{% csrf_token %}
{{ form.as_p }}
<input type="submit" value="Update" />
</form>
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.

该视图从以下视图继承方法和属性：
属性
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'.
示例 myapp/views.py：
from django.views.generic.edit import DeleteView
from django.core.urlresolvers import reverse_lazy
from myapp.models import Author
class AuthorDelete(DeleteView):
model = Author
success_url = reverse_lazy('author-list')
示例 myapp/author_confirm_delete.html：
<form action="" method="post">{% csrf_token %}
<p>Are you sure you want to delete "{{ object }}"?</p>
<input type="submit" value="Confirm" />
</form>
