Creating a comment system

Now, we will build a comment system for the blog, wherein the users will be able to comment on posts. To build the comment system, you will need to do the following steps:

  1. Create a model to save comments
  2. Create a form to submit comments and validate the input data
  3. Add a view that processes the form and saves the new comment to the database
  4. Edit the post detail template to display the list of comments and the form to add a new comment

First, let's build a model to store comments. Open the file of your blog application and add the following code:

class Comment(models.Model): 
post = models.ForeignKey(Post,
name = models.CharField(max_length=80)
email = models.EmailField()
body = models.TextField()
