How to get the submitted value of a form in a Django class-based view?

问题

I have a Django form that looks like this:

class myForm(forms.Form):
    email = forms.EmailField(
        label="Email",
        max_length=254,
        required=True,
    )

I have a an associated Class-Based FormView as shown below. I can see that the form is succesfully validating the data and flow is getting into the form_valid() method below. What I need to know is how to get the value that the user submitted in the email field. form.fields['email'].value doesn't work.

class myFormView(FormView):
    template_name = 'myTemplate.html'
    form_class = myForm
    success_url = "/blahblahblah"


    def form_valid(self, form):
        # How Do I get the submitted values of the form fields here?
        # I would like to do a log.debug() of the email address?
        return super(myFormView, self).form_valid(form)

You can check the form's cleaned_data attribute, which will be a dictionary with your fields as keys and values as values. Docs here.

Example:

class myFormView(FormView):
    template_name = 'myTemplate.html'
    form_class = myForm
    success_url = "/blahblahblah"


    def form_valid(self, form):
        email = form.cleaned_data['email'] <--- Add this line to get email value
        return super(myFormView, self).form_valid(form)

try this:

 form.cleaned_data.get('email')
