如何在基于 Django 类的视图中获取表单的提交值? [英] How to get the submitted value of a form in a Django class-based view?

问题描述

我有一个像这样的 Django 表单:

I have a Django form that looks like this:

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

我有一个关联的基于类的 FormView，如下所示.我可以看到表单正在成功验证数据，并且流程正在进入下面的 form_valid() 方法.我需要知道的是如何获取用户在电子邮件字段中提交的值.form.fields['email'].value 不起作用.

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)

推荐答案

您可以检查表单的 cleaned_data 属性，该属性将是一个以您的字段作为键和值作为值的字典.文档此处.

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.

示例:

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)
