Using a form in a viewpretty much explains it.
在视图中使用表单几乎可以解释它。
The standard pattern for processing a form in a view looks like this:
在视图中处理表单的标准模式如下所示：
def contact(request):
if request.method == 'POST': # If the form has been submitted...
form = ContactForm(request.POST) # A form bound to the POST data
if form.is_valid(): # All validation rules pass
# Process the data in form.cleaned_data
# ...
print form.cleaned_data['my_form_field_name']
return HttpResponseRedirect('/thanks/') # Redirect after POST
else:
form = ContactForm() # An unbound form
return render_to_response('contact.html', {
'form': form,
})

You can do this after you validate your data.
您可以在验证数据后执行此操作。
if myform.is_valid():
data = myform.cleaned_data
field = data['field']
Also, read the django docs. They are perfect.
另外，请阅读 django 文档。他们是完美的。

I use django 1.7+ and python 2.7+, the solution above dose not work. And the input value in the form can be got use POST as below (use the same form above):
我使用 django 1.7+ 和 python 2.7+，上面的解决方案不起作用。并且表单中的输入值可以使用 POST 获取，如下所示（使用与上面相同的表单）：
if form.is_valid():
data = request.POST.get('my_form_field_name')
print data
Hope this helps.
希望这可以帮助。

Take your pick:
随你挑：
def my_view(request):
if request.method == 'POST':
print request.POST.get('my_field')
form = MyForm(request.POST)
print form['my_field'].value()
print form.data['my_field']
if form.is_valid():
print form.cleaned_data['my_field']
print form.instance.my_field
form.save()
print form.instance.id # now this one can access id/pk
Note: the field is accessed as soon as it's available.
注意：该字段一可用就被访问。

To retrieve data from form which send post request you can do it like this
要从发送发布请求的表单中检索数据，您可以这样做
def login_view(request):
if(request.POST):
login_data = request.POST.dict()
username = login_data.get("username")
password = login_data.get("password")
user_type = login_data.get("user_type")
print(user_type, username, password)
return HttpResponse("This is a post request")
else:
return render(request, "base.html")
