Django Inlineformset

Hi, I wanted to create a blog where some one a button to add titles and subtitles. I also wanted to create a dynamic form where one can interact with it and can add multiple images and videos
Here is the file

from django.db import models
from django.contrib.auth.models import User

class PublishedManager(models.Manager):
    def get_queryset(self):
        return super(PublishedManager, self).get_queryset().filter(status='published')

class Article(models.Model):
    state = (
        ('draft', 'Draft'),
        ('published', 'Published')
    author = models.ForeignKey(User, on_delete=models.CASCADE)
    title = models.CharField(max_length=1000, unique=True)
    slug = models.SlugField(max_length=250, unique=True)
    status = models.CharField(max_length=11, choices=state, default="draft")
    publish = models.DateTimeField(
    created = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)
    objects = models.Manager() 
    published = PublishedManager() 
    tags = TaggableManager()
    class Meta:
        ordering = ('-publish',)
    def __str__(self):
        return self.title

    def get_absolute_url(self):
        return reverse('Article:Article_list', kwargs={"pk":})
class Add_image(models.Model):
    image = models.ImageField(upload_to='images/', null=True, blank=True)
    article = models.ForeignKey(Article, on_delete=models.CASCADE)
    def __str__(self):
        return self.article.title
class Add_body(models.Model):
    body = models.TextField()
    article = models.ForeignKey(Article, on_delete=models.CASCADE)
    def __str__(self):
        return self.article.title
class Add_video(models.Model):
    video = models.FileField(upload_to='video/')
    article = models.ForeignKey(Article, on_delete = models.CASCADE)
    def __str__(self):
        return self.article.title

Pls, help me out

Note: When posting code here, enclose the blocks of code between lines of three backtick - ` characters. That means you’ll have a line of ```, then your code, then another line of ```. This forces the forum software to keep the code properly formatted. (You don’t need to repost your code - you can edit your code and insert the ``` before and after each chunk of code.)

So what specifically do you need assistance with? What is the problem you are having?

I want to build a blog where you can insert images, videos and text bodies at different points. Like medium, when you are writing there, you can insert many things like codes, images, videos.


But what question do you have, or what is the issue that you are facing?

Have you written a “blog” project before that you are extending? Or is this something you’re starting from scratch?

So yes, I have been able to create the Create view view section. So, I am having issues with the DetailView. When I try, error comes as Model no attributed pk. What should I do?
Here is the GitHub link

Please post the text of the entire traceback message including the error.

I’m sorry, this error message doesn’t match either the code you posted here or what’s checked into your repo.

So I guess your first step is to ensure you’re running what you think you’re running.
