rails relationship model ( like/unlike button)

Question

I am trying to create and implement a like/unlike button to a post model in rails. The only thing I sort of understand is I need some sort of relationship model with a has_many_through association. can any one point me in the right direction to create this. I will prefer to create it from scratch to full understand it. thanks

you need to tell us what you've already done. we can help in any difficulty you've encountered but you need to let us know that you've really done something first :) — jvnill, Mar 06 '13 at 06:00

Well, it seems like you have a Person model. And you have a Post model. That Person model can be related to a Post model through something like an Opinion model (ugh... I hate trying to name relational models -- but the only thing I despise more would be a PersonPost model -- its not a PersonPost -- the person making the vote up or down isn't the poster - but enough of that). Opinion has a person_id and a post_id (and whatever other fields you think are useful).

So Person has_many :opinions has_many :posts, :through => :opinions

Opinion belongs_to :person belongs_to :post

Post has_many :opinions has_many :people, :through => :opinions

Extend from there.

Ok, i see where you are coming from. Thanks, will try and extend. — , Mar 06 '13 at 06:16
