FieldError — Unknown field(s): django-fluent-contents - django

Question

I'm a Python/Django noob. So any help will be appreciated.
Trying to use the django-fluent-contents
models.py
from django.core.urlresolvers import reverse
from django.db import models
from fluent_contents.models.fields import PlaceholderField, PlaceholderRelation, ContentItemRelation
from fluent_contents.models import ContentItem
class Article(models.Model):
title = models.CharField("Title", max_length=200)
slug = models.SlugField("Slug", unique=True)
content = PlaceholderField("article_content")
placeholder_set = PlaceholderRelation()
contentitem_set = ContentItemRelation()
class Meta:
verbose_name = "Article"
verbose_name_plural = "Articles"
def __unicode__(self):
return self.title
def get_absolute_url(self):
return reverse('article-details', kwargs={'slug': self.slug})
admin.py
from django.contrib import admin
from article.models import Article
from fluent_contents.admin import PlaceholderFieldAdmin
class ArticleAdmin(PlaceholderFieldAdmin):
prepopulated_fields = {'slug': ('title',)}
fieldsets = (
(None, {
'fields': ('title', 'slug', ),
}),
("Contents", {
'fields': ('content',),
'classes': ('plugin-holder',),
})
)
admin.site.register(Article, ArticleAdmin)
I'm using South for migration.
db.create_table(u'article_article', (
(u'id', self.gf('django.db.models.fields.AutoField')(primary_key=True)),
('title', self.gf('django.db.models.fields.CharField')(max_length=200)),
('slug', self.gf('django.db.models.fields.SlugField')(unique=True, max_length=50)),
))
db.send_create_signal(u'article', ['Article'])
It looks like, no column is being created for the 'content' field.
So when I try to add a new 'Article' via django admin —
FieldError at /manage/article/article/add/
Unknown field(s) (content) specified for Article. Check fields/fieldsets/exclude attributes of class ArticleAdmin.
If I remove the fieldset from admin.py
class ArticleAdmin(PlaceholderFieldAdmin):
prepopulated_fields = {'slug': ('title',)}
admin.site.register(Article, ArticleAdmin)
The 'content' field is not shown in django admin
In reply to #vdboor.. Here's my installed apps ...
INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.messages',
'django.contrib.staticfiles',
'django.contrib.admin',
# Uncomment the next line to enable admin documentation:
# 'django.contrib.admindocs',
# 3rd party apps
'south',
'django_extensions',
'compressor',
'debug_toolbar',
'fluent_contents',
'fluent_contents.plugins.text',
'django_wysiwyg',
# Project specific apps go here
'article',
)
Also I'm using the example app from the repo as a guide... just removed the extra plugin model
FYI I'm using
Django==1.6
MySQL-python==1.2.4
South==0.8.4
Thank you for all the help :-)

Answer 1

It looks like, no column is being created for the 'content' field.
That is correct, the PlaceholderField becomes a reverse-generic-relation.
You can try removing the fieldsets declaration for now, and see what other error you get.
The repository also contains an example application, which you can run, and compare with your app.
Silly question, but is fluent_contents in the INSTALLED_APPS?

Answer 2

Still need to add extra fields. In the example shown, because the content is stored in a separate table - model ContentItem.
from fluent_contents.models.fields import PlaceholderField, PlaceholderRelation, ContentItemRelation
class Article(models.Model):
title = models.CharField("Title", max_length=200)
slug = models.SlugField("Slug", unique=True)
content = PlaceholderField("article_content")
placeholder_set = PlaceholderRelation() # <-- this
contentitem_set = ContentItemRelation() # <-- and this
class Meta:
verbose_name = "Article"
verbose_name_plural = "Articles"
