问题 I'm using exclude in my form's Meta class to exclude a field from my form that I want to fill in programatically, but it's still showing up in the form.

问题 Hi I have written a def clean(self) function in forms to make sure that if there was previously already a post with the same title, they will return a message saying that the title already exists and hence the form cannot be submitted.
