I'm working through the book Django 2 By Example, in which I'm trying to build a blog application with tagging functionality.
My code for including django-taggit (after installing version 0.22.2 with pip) is the following.
Add the app to INSTALLED_APPS:
INSTALLED_APPS = [
#...
'blog.apps.BlogConfig',
'taggit',
]
Add TaggableManager provided by django-taggit to Post model.
from django.db import models
from django.utils import timezone
from django.contrib.auth.models import User
from django.urls import reverse
from taggit.managers import TaggableManager
# Create your models here.
class PublishedManager(models.Manager):
def get_queryset(self):
return super(PublishedManager, self).get_queryset().filter(status='published')
class Post(models.Model):
STATUS_CHOICES = (
('draft', 'Draft'),
('published', 'Published'),
)
title = models.CharField(max_length=250)
slug = models.SlugField(max_length=250, unique_for_date='publish')
author = models.ForeignKey(User, on_delete=models.CASCADE, related_name='blog_posts')
body = models.TextField(default='')
publish = models.DateTimeField(default=timezone.now)
created = models.DateTimeField(auto_now_add=True)
updated = models.DateTimeField(auto_now=True)
status = models.CharField(max_length=10, choices=STATUS_CHOICES, default='draft')
objects = models.Manager() # The default manager.
published = PublishedManager() # Our custom manager.
tags = TaggableManager()
def get_absolute_url(self):
return reverse('blog:post_detail',
args=[self.publish.year,
self.publish.month,
self.publish.day,
self.slug])
class Meta:
ordering = ('publish',)
def __str__(self):
return self.title
When I add the line tags = TaggableManager() to the Post model, I get the following error when trying to add a new post or edit an existing post via the admin site:
TypeError: render() got an unexpected keyword argument 'renderer'.
I have no idea why this error is being generated, so any advice would be greatly appreciated.
