how to add additional data to that submitted by the user in a django form

I am trying to create a form in which the user enter details like his email id and query.

After the form is submitted i have to save the data that I get from the form along with some additional info such as userid , submitted date and time, etc into the database.

What approach should be adopted for solving this problem?
