如何从Django框架的表单字段中获取价值？

How do I get values from form fields in the django framework? I want to do this in views, not in templates…

Using a form in a view pretty much explains it.

The standard pattern for processing a form in a view looks like this:

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,
    })

Take your pick:

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.

You can do this after you validate your data.

if myform.is_valid():
  data = myform.cleaned_data
  field = data['field']

Also, read the django docs. They are perfect.

To retrieve data from form which send post request you can do it like this

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")

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):

if form.is_valid():
  data = request.POST.get('my_form_field_name')
  print data

Hope this helps.
