Creating Reviews and Star Rating Feature in Django | E-commerce Website using Django | EP. 22 [1/2]

Reviews and star ratings are crucial features for any e-commerce website as they help in building trust and confidence among the users. In this tutorial, we will walk through the process of creating a review and star rating feature in a Django e-commerce website.

Setting Up the Database Model

First, we need to create a database model to store the reviews and star ratings for the products. We can create a separate model for reviews and link it to the product model using a foreign key relationship. The review model can have fields like user, product, rating, and comment.

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

class Product(models.Model):
    name = models.CharField(max_length=100)
    price = models.DecimalField(max_digits=10, decimal_places=2)
    # other product fields

class Review(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    product = models.ForeignKey(Product, on_delete=models.CASCADE)
    rating = models.IntegerField()
    comment = models.TextField()

Creating the Review Form

Next, we need to create a form for users to submit their reviews and star ratings for the products. We can use Django’s forms module to create a simple form for this purpose. The form can have fields for rating and comment.

from django import forms
from .models import Review

class ReviewForm(forms.ModelForm):
    class Meta:
        model = Review
        fields = ['rating', 'comment']

Displaying Reviews and Star Ratings

Finally, we need to display the reviews and star ratings on the product detail page. We can query the database for the reviews related to the current product and display them along with the average star rating for the product.

{% for review in product.review_set.all %}
  
{{ review.user.username }} - {{ review.rating }} stars
  
{{ review.comment }}
{% empty %}
  
No reviews yet.
{% endfor %}

With these steps, you can successfully create a review and star rating feature for your Django e-commerce website. Stay tuned for the next part where we will cover the implementation of user authentication and validation for the reviews.
