Trying to figure out what the relationship between my post topic and post like would be

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 ManyToManyField on the user field in the PostLike model.
  • Relationship with Post: Similar to the user, this is also a Many-to-Many relationship. A PostLike instance connects a specific user to a specific post they liked. This is reflected by the ForeignKey on the post field in the PostLike model.

  User <-->|likes| PostLike
  PostLike -->|liked by| Post

In this diagram:

  • Rectangles represent classes (models) with their names inside.
  • Lines represent relationships between classes.
  • Crow’s feet (<--> ) represent a Many-to-Many relationship.
  • An arrow (-> ) represents a One-to-Many or ForeignKey relationship. Here, it shows a PostLike instance belongs to a single User and a single Post .
  • Labels on the lines describe the relationship (“likes” and “liked by”).
