There are two ways to achieve what you want I think:

1. Provide an initial value for your form value.
2. Bind your form to some data.

See this related stack overflow to provide initial values.

See Django's documentation on forms for binding data. There are two kinds of form states: bound and unbound. To create a bound form, you just need to create an instance of your form with some data: MyForm({'data-key1': 'data-value1', ...}).
