Hi all,
I'm trying to enhance a form in the admin site for a given model (Django
1.3). The relevant part of the model is the following
class Project(models.Model):
[...]
icon = models.ForeignKey(Icon, null=True)
[...]
and the admin is a simple call to admin.site.register().
This way I get a very nice form with a drop down menu listing all the Icon
object unicode() calls.
I would like to replace the widget with an image drop down menu made with
javascript, so I did the following
class AdminImageSelectorWidget(forms.Select):
pass
class ProjectForm(forms.ModelForm):
icon = forms.ChoiceField(widget=AdminImageSelectorWidget)
class Meta:
model = Project
class ProjectAdmin(TranslationAdmin):
form = ProjectForm
which is basically just a wrap of the existing structure: by customizing
the render() method of AdminImageSelectorWidget I think I should be able to
get what I want.
First question: is this the correct way to achieve a widget customization?
Second question: by doing this I lose the useful "+" button near the drop
down menu, which lets the users to add a new object. I found that the class
behind this button is RelatedFieldWidgetWrapper, but I do not understand if
I can use it on my widget and how.
Someone can enlighten me?
Thank you very much in advance
Leo
