Hello,
I seem to have a problem with the newforms-admin revision 6373. When I
have a recursive many2many it fails. The top of the call stack start
at self.base_fields.copy() . For the simple example below when I click
on the add keyword in the admin interface. I get the following stack.
I also get the same error when I have related inline fields. I am new
to this. Perhaps I am intruding on the developers-group. I think I
really should raise something like a ticket. However I am posting here
until I figure the ticket system out.
Example:
from django.db import models
from django.contrib import admin
from django import newforms as forms
class Keyword(models.Model):
"""A tag on an item."""
keyword =
models.CharField(max_length=KEYWORD_MAX_LENGTH,unique=True)
description = models.TextField(blank=True,null=True)
thesarus =
models.ManyToManyField('Keyword',blank=True,null=True)
def __str__(self):
return self.keyword
class Admin:
pass
class KeywordOptions(admin.ModelAdmin):
list_display = ('keyword','description')
