I’ve got a Post and User classes. The Post has a user_id attribute to
point to the user that created it.
I want to implement favorites, so I made Post and User both
“has_and_belongs_to_many” and created a favorites join table. The
join table has a post_id and a user_id column.
Now when I get my post everything seems to be okay, but in some
contexts, the user_id get’s overwritten. I think that the user_id
from the join table is being merged into my Post instance.
What would you do differently so that there was no collision between
my Post’s user_id (the author) and the join table’s user_id (for whom
this post is a favorite)?
