Django's forms are powerful and simple to use. In most cases, you'll be declaring your fields explicitly. But sometimes you need dynamic forms, and overriding some class methods will let you do just that. This post will show you what to do.
Let's say you want to dynamically add a field to a model form if the user hasn't provided a first name.
First, we declare our model form:
1 2 3 4 5 6 | from django import forms from models import Widget class WidgetModelForm(forms.ModelForm): class Meta: model = Widget |
Now we override the constructor, adding our field:
1 2 3 4 5 6 7 8 | class WidgetModelForm(forms.ModelForm): def __init__(self, request, *args, **kwargs): super(WidgetModelForm, self).__init__(*args, **kwargs) if not request.user.first_name: self.fields['first_name'] = forms.CharField() class Meta: model = Widget |
And that's it. Somewhere in our app views, we'd use this form like so:
1 2 3 | def my_view(self, request): form = WidgetModelForm(request, request.POST or None) # .. and so on |
A few notes:
Looking to use dynamic forms in the admin? Be sure to read the follow up post.

Il y a toujours un problème dans le processus de vente, c'est-à-dire que le client a une méfiance vis-à-vis du personnel de vente. Ils pensent que les informations obtenues auprès du personnel de vente de la cartier Montre auront souvent des degrés différents d'exagération et de fausseté, aussi être une fraude. Par conséquent, de nombreux clients pensent que les paroles du vendeur peuvent être entendues ou non dans le processus de communication avec le personnel de vente, ne s'en soucient souvent pas trop et même se disputer avec le personnel de vente avec une psychologie rebelle.breitling Montre
