I’m using polymorphic association on my Review model for User and Post.
However i would also make sense to have a owner for each review.

BY owner i mean a associated user model. But this bring problems on the table since users can review and has reviews from other users

What is the best way to go about. Any ideas of solutions are welcome.

Review.rb

belongs_to :reviewable, polymorphic: true
belongs_to :user # owner of the reviews

User.rb

  # reviews from others
  has_many :reviews, as: :reviewable, dependent: :destroy 
  has_many :reviews  # user written reviews

Post.rb

  has_many :reviews, as: :reviewable, dependent: :destroy

    The obvious problem is that you have two associations in your User model with the same name. One simple fix is to rename one of them. Since your Post already has a reviews association that matches a similar reviews polymorphic association, you could rename the user written reviews to be something like this:

    has_many :reviews_by_me, class_name: 'Review'

    By specifying the class name, Rails can then infer the rest of the information and get you the correct Review objects where user_id matches on your User.
