The relationship between your models for post likes and users is already defined correctly using a ManyToManyField . Here’s a breakdown:
- Model:
PostLike - Relationship with User: This is a Many-to-Many relationship. One user can like many posts, and one post can be liked by many users. This is reflected by the
ManyToManyFieldon theuserfield in thePostLikemodel. - Relationship with Post: Similar to the user, this is also a Many-to-Many relationship. A
PostLikeinstance connects a specific user to a specific post they liked. This is reflected by theForeignKeyon thepostfield in thePostLikemodel.
