[Answer]-POST role when updating records in the database using the conservation form

In both cases you actually pass the request.POST dictionary as a single argument to the form’s __init__ method. That way the form can differentiate the actual post data and other arguments. The request.POST dictionary is in its completeness saved in the data attribute. Later on, in the is_valid method, the keys and values in the dictionary are checked against the form’s fields and used to validate the form and populate the cleaned_data attribute.
