Overriding the HTML id in ModelForm

[Romain]

Hello,

On the same page I have 2 ModelForm that happen to have an attribute
with the same name. Is it possible to choose the name of the HTML id
generated by the form without having to change the real name of the
model attribute?

e.g.
class A(models.Model):
amount = models.IntegerField()

class B(models.Model):
amount = models.IntegerField()


class AForm(ModelForm):
class Meta:
model = A

class BForm(ModelForm):
class Meta:
model = B

Conflict of ids when forms printed:
...
<input type="text" name="amount" id="id_amount" />
...
<input type="text" name="amount" id="id_amount" />
...

Thanks a lot,

Romain

A simple solution would be to instantiate your ModelForms with a prefix:
http://docs.djangoproject.com/en/dev/ref/forms/api/#prefixes-for-forms

Another, finer-grained choice is using the auto_id argument:
http://docs.djangoproject.com/en/dev/ref/forms/api/#configuring-html-label-tags

Hope that's what you're looking for,

Auto_I'd won't help. The issue is the names conflict in the POST so
this is an issue for prefix.

Thanks a lot for the great answers, and the information about the form
prefix (it is what I was looking for)!

Sorry, I missed the replies 1 week ago :(

Thanks again,

Romain
