返回浏览器后，如何以django形式获取字段的现有值？

Question

I'm trying to understand how django populates the data in a form when I go back in a browser

In the debugger when I go back in the browser it generates a GET request, not a POST and so the form is not bound and has no self.data .

How do I get the existing values of the fields in a django form when going back in the browser?

(note I am using session with database backend)

Answer 1

While creating the form use initial data.

data = { 'field_1': 'value'}
my_form = MyForm(initial=data)

Answer 2

The error is in the question. The data is coming from the browser cache not the backend.
