Hi,
I'm trying to modify my blogging application using the new
GenericRelation and GenericForeignKey, keeping the tagging concept as
easy as posible.
The problem is, once the modifications made, I can not find a tag
field in the Admin interface. It says "Could not find Formfield or
InlineObjectCollection named 'tags'". The doc is yet a bit light on
this, so I can not find any info.
Is it normal? Is there a way of circunventing this?
Thanks,
G
The code:
class Tag(models.Model):
slug=models.SlugField(prepopulate_from=('title',),
help_text='Automatically built from the title',
primary_key=True)
title = models.CharField(maxlength=30)
description=models.CharField(maxlength=200,help_text='Short
summary of this tag')
tagged_obj=models.GenericForeignKey()
def get_absolute_url(self):
return '/tags/%s/' % self.slug
def get_list(self):
return self.post_tagged.all()
def __str__(self):
return self.title
def __repr__(self):
return self.title
class Admin:
list_display = ('title','description')
search_fields = ('title','description')
fields = ((None, {'fields':('title','description','slug'),}),)
class Post(models.Model):
slug = models.SlugField(prepopulate_from=('title',),
help_text='Automatically built from the title',
primary_key=True)
title = models.CharField(maxlength=79)
creation_date = models.DateTimeField(auto_now=True)
body = models.TextField('Body Text')
summary = models.TextField(maxlength=300,
blank=True,
help_text='Will be displayed on article indexes'+
'if it exists, otherwise full body will be used')
tags = models.GenericRelation(Tag)
image = models.ImageField('Attach Image',
upload_to='sysvortex/blog',
blank=True)
author = models.ForeignKey(User)
to_publish = models.BooleanField(default=False,
help_text='Draft entries are visible only'+
'to the authors and admins',
radio_admin=True)
enable_comments = models.BooleanField(default=True)
def get_absolute_url(self):
return '/blog/%s/%s/' %
(self.creation_date.strftime('%Y/%m/%d').lower(),
self.slug)
def get_tag_list(self):
return self.tags.all()
def __str__(self):
return self.title
def __repr__(self):
return self.title
class Admin:
list_display =
('title','creation_date','author','to_publish','enable_comments')
list_filter = ['creation_date','enable_comments']
date_hierarchy = 'creation_date'
list_select_related = 'True'
search_fields = ['title','summary','body']
ordering = ('-creation_date','to_publish')
js = ('tiny_mce/tiny_mce.js',
'js/admin/textareas.js',)
fields = (
(None, {'fields':('title','to_publish','enable_comments'),}),
('Other information', {'fields':('slug','author','creation_date'),
'classes': 'collapse'}),
('Post', {'fields':('summary','image','body',),
'classes':'wide', }),
)
