问题
In my case, the Django app is saving and getting user data to/from an external service via an API. I get an object with a number of user attributes, e.g. name, address, etc.
For updating of such information I'm using Django's native forms, with the shorthand template format, say: {{ edit_account_form.as_p }}
When I display the form to edit the information, I'd like to pre-populate it with the data from the user object. I know that I can pass the object into the template and render those values into the val and placeholder of each input field, however that would requite that I completely recreate the form input by input, which I'd prefer not to.
Possible?

Use initial to declare the initial value of form fields at runtime. For example, you might want to fill in a username field with the username of the current session.
f = ContactForm(initial={'subject': 'Hi there!'})
