It is defintely worth using django where possible to do what it can (otherwise why use django!). The form stuff can do loads for you (validation for one).
http://www.djangoproject.com/documentation/modelforms/ and http://www.djangoproject.com/documentation/models/model_forms/ Are really useful. If the input tags don't display the way you like, you can either write your own widgets, or define a class for them and use CSS (depending on what you want to do). Here is a really cut down version of what you can do to get django to display a form from a model (not very well coded but simple). In your view... def my_view(request) if request.method == 'POST': f = ContactForm(request.POST) if f.is_valid(): f.save() return HttpResponseRedirect('/home/') else: f = ContactForm() return render_to_response('contact.html', locals()) In the contact.html template ... <form action="." method = "POST"> <table> {{ f.as_table } </table> <input type="submit" value="Save" /> <input type="reset" value="reset" /> </form> .... That should get you started, but the docs are good and it is worth going through them. Of course you don't have to do f.as_table, you can access the fields and display them where you like, but best to start with the basics to understand how django works first.
