Re: Populating a form from the database
Hi, if you use ModelForm, the data from the database are the initial form data. If you create a new record with ModelForm, you could use the "initial" parameter to supply some default values. More can be found in the docs.

Populating a form from the database
Short: How do I populate a form with data from the database? Fx. if I want to let users edit the data they have entered. Long: Currently, I have a form where the user(if logged in) will enter data and when it is submitted some extra data is entered to the form before it is saved, a time-stamp and the request.user . But is there a way to open the form, looking to see if the user already has entered some data, then populate the form with that data. But if the user does not have a entry in the database, then presenting an empty form. ? -- MV --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

DateField format with a ModelForm: populating the form from a model instance
Hi, I've written my own view to create / edit model instances my project, and part of what I wanted to do was to accept dates only in the format dd-mm- (%d-%m-%Y). I searched around a bit and came accross this post: http://groups.google.com/group/django-users/browse_thread/thread/9f84d1b920e54dd2/bbc7857c120c8ecb. Creating my own model field class seemed pretty extreme, but I quickly worked out that I can do this much more simply by adding a line to my ModelForm: class EventForm(ModelForm): start_date = forms.DateField(input_formats=['%d-%m-%Y']) This changes the behaviour, and works fine for validating dates written in non- US format. My problem is that when I create an EventForm from a model instance (for my 'edit' functionality) the date fields (rendered as html text inputs) are populated in the standard %Y-%m-%d format. Submitting the form as populated is therefore invalid, so I have to manually play with the dates each time I edit an event. How would I go about changing this behaviour? I understand that patch 1.1 might address this (by typing date format to locale), but I would like to see if I can knock up a temporary solution.

Re: Populating a form
You'll need to load an instance of the model, which will pre-populate the data: http://www.djangoproject.com/documentation/newforms/#form-for-instance On Sep 11, 7:15 am, AniNair <[EMAIL PROTECTED]> wrote: > Hi... >I am trying to learn python and django.
