Python And Django : Part 13 : Blog Comments

Welcome to Part 13 of our Python and Django tutorial series. In this tutorial, we will be discussing how to implement blog comments in a Django web application.

Setting Up The Comment Model

First, we need to create a new model for comments in our Django application. We can do this by creating a new Python file in our app’s models.py and adding the following code:

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

            class Comment(models.Model):
                author = models.ForeignKey(User, on_delete=models.CASCADE)
                content = models.TextField()
                post_date = models.DateTimeField(auto_now_add=True)
        
    

Implementing Comment Forms

Next, we need to create a form for users to submit comments on blog posts. We can do this by creating a new Python file in our app’s forms.py and adding the following code:

        
            from django import forms
            from .models import Comment

            class CommentForm(forms.ModelForm):
                class Meta:
                    model = Comment
                    fields = ['content']
        
    

Displaying Comments in Templates

Now that we have our model and form set up, we can display comments on our blog post templates. We can do this by looping through all comments related to a specific blog post and displaying them. Here is an example of how to do this in a template file:

        
            {% for comment in blogpost.comments.all %}
                

                    
{{ comment.author }} says: {{ comment.content }}
                    
Posted on: {{ comment.post_date }}
                
            {% endfor %}
        
    

Conclusion

Congratulations! You have successfully implemented blog comments in your Django web application. Users can now leave feedback and engage with your content. Stay tuned for more tutorials on Python and Django.
