Working with ModelForms for Database Interaction

A plain form for the blog's Article model would repeat five field definitions that the model already contains, with the same names, the same types and the same 200-character limit on the title. Every later change to the model would then have to be made twice. A ModelForm removes that repetition. It reads the fields from the model, builds the matching form fields, validates the data against the model's rules, and saves the result as a database row with one call.
