How To Nest These Serializes Without Facing Attributeerror: 'blogpost' Object Has No Attribute 'review_set'

I followed Dennis Ivy proshop Tutorial He used the same approach as the code is class ReviewSerializer(serializers.ModelSerializer): class Meta: model = Review

Solution 1:

The simplest solution is to update your get_blog_post_reviews method:

defget_blog_post_reviews(self, obj):
    blog_post_reviews = obj.blogpostreview_set.all()  # <- this line has changed
    serializer = BlogPostReviewSerializer(blog_post_reviews, many=True)
    return serializer.data

The original worked because there was a model named Review, so the automatically created reverse name was review_set. Your model is named BlogPostReview, so the reverse is blogpostreview_set.

More information about reverse relationships in the docs.
