I have problem with contrib.admin application. Consider we have demo
application with this three files:
demo/models.py:
{{{
from django.db import models
class Demo(models.Model):
name = models.CharField(max_length=100)
note = models.TextField(blank=True, null=True)
}}}
demo/admin.py:
{{{
from django.contrib import admin
from models import Demo
from forms import DemoAdminForm
class DemoAdmin(admin.ModelAdmin):
readonly_fields = ('name', )
form = DemoAdminForm
admin.site.register(Demo, DemoAdmin)
}}}
demo/forms.py:
{{{
from django import forms
from models import Demo
class DemoAdminForm(forms.ModelForm):
class Meta:
model = Demo
exclude = ('note', )
}}}
If I go to administration, and edit some Demo object, I see two fields:
editable Note and readonly Name. But! I should see only readonly Name
(because I use own ModelForm class which excluded note field). Try to
comment line "readonly_fields = ('name', )" at admin.py file. You will
see, that in this situation (no readonly attribute on ModelAdmin) Django
correctly accept Meta class on ModelForm and exclude field Note.
I think that there is a problem in the way, how Django construct ModelForm
class. It don't respect Meta classes in Form, if there is at same time
readonly attribute on ModelAdmin.
