Question

I have a Post, and an User model

I want to enable users to save or bookmark posts. In other words, they will click a button and the post will be bookmarked/saved. Then the user will be able to see all those posts listed in a page (like YouTube’s watch later).

I think I have to create a Bookmark model. But I’m not sure what kind of assosiation the models should have with Post and User.

Any suggestions?

Answer 1

If you just want to have bookmarks but no other information associated with the bookmark like ‘bookmarked comment’ or ‘blah blah’ you can use has_and_belongs_to_many association. There you won’t need to create a bookmark model. You only need to create the join table in this case. The has_many :through is useful in a case when you need to store more information with the relationship. You can go through this has_and_belongs_to_many_association for more information.
