Adding Tags Using Django-Taggit in Django Project

Last Updated : 18 Apr, 2022

Django-Taggit is a Django application which is used to add tags to blogs, articles etc. It makes very easy for us to make adding the tags functionality to our django project.
Setting up Django Project

Installing django-taggit

pip install django-taggit

ADD it to Main Project's settings.py file

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.humanize',
    'taggit'
]

Changes To models.py file

Add TaggableManager in your post, blog, article modal

from django.db import models
from django.utils.timezone import now 
from taggit.managers import TaggableManager

class Post(models.Model):
    postid = models.AutoField(primary_key=True)
    title = models.CharField(max_length=255)
    content = models.TextField()
    author = models.CharField(max_length=100) 
    postauthor = models.ForeignKey(User, on_delete=models.CASCADE)
    slug = models.SlugField(unique=True)
    category = models.CharField(max_length=200) 
    timestamp = models.DateTimeField(default=now, blank=True)
    tags = TaggableManager()

After adding TaggableManager run following commands in terminal

python manage.py makemigrations
python manage.py migrate

The TaggableManager will show up automatically as a field in post modal

The Taggit Modal will also appear automatically as a separate modal in admin panel

Adding tags

1) If the tags input doesn’t contain any commas or double quotes, it will be taken as space-delimited list of
tag names.

geeks for geeks => "geeks", "for", "geeks"

2) If the tags input does contain commas or double quotes then :

       
a) geeks, geeks for geeks            =>   "geeks", "geeks for geeks" 
b) "geeks, forgeeks" geek geeksfor   =>   "geeks, forgeeks", "geek", "geeksfor"
c) "geeks, forgeeks", geek geeksfor  =>   "geeks, forgeeks", "geeks geeksfor"
d) geeks "for" geeks                 =>   "geeks", "for", "geeks"

After Adding Tags to the posts the taggit modal will look like :

All the tags which are associated with different posts will appear in tags modal under taggit

On clicking the particular tag, There will come a list of all the posts associated with that particular tag. Now this model can be used with the project like other models
