Python generic.FormView方法代码示例

        """ Provide custom behavior on invalidation to compensate for lack of template.

        The default behavior from FormView is to try rendering a template with
        errors for the user. However, since the attended lectures form is
        tremendously simple (a hidden input with participant ID, and a submit
        button), there really isn't any errors we can give to the user.

        We can expect an invalid form submission when:
        1. A participant loads the attendance form (while self-submission is allowed)
        2. The Winter School chairs disable lecture sign-in
        3. The participant then tries to submit the form, but is not allowed
