I would like to add some extra fields to pages in django-cms (in django admin panel). How do this in the simplest way?
Create a new app (called extended_cms
or something) and in models.py
create the following:
from django.db import models
from django.utils.translation import ugettext_lazy as _
from cms.models.pagemodel import Page
class ExtendedPage(models.Model):
page = models.ForeignKey(Page, unique=True, verbose_name=_("Page"), editable=False, related_name='extended_fields')
my_extra_field = models.CharField(...)
then create an admin.py
:
from models import ExtendedPage
from cms.admin.pageadmin import PageAdmin
from cms.models.pagemodel import Page
from django.contrib import admin
class ExtendedPageAdmin(admin.StackedInline):
model = ExtendedPage
can_delete = False
PageAdmin.inlines.append(ExtendedPageAdmin)
try:
admin.site.unregister(Page)
except:
pass
admin.site.register(Page, PageAdmin)
which will add your extended model to as an inline to any page you create. The easiest way to access the extended model setttings, is to create a context processor:
from django.core.cache import cache
from django.contrib.sites.models import Site
from models import ExtendedPage
def extended_page_options(request):
cls = ExtendedPage
extended_page_options = None
try:
extended_page_options = request.current_page.extended_fields.all()[0]
except:
pass
return {
'extended_page_options' : extended_page_options,
}
and now you have access to your extra options for the current page using {{ extended_page_options.my_extra_field }}
in your templates
Essentially what you are doing is creating a separate model with extra settings that is used as an inline for every CMS Page. I got this from a blog post previously so if I can find that I'll post it.
