Question

New to rails here. My associations are setup as below, it might not be the ideal way so any recommendation is greatly welcomed:

User has many posts (posts table has user_id)
User has one profile (profile table has user_id)

Within my post controller view, I want to display the name of the profile (profile.name) that belongs to the user who owns the post.

My naive first guess was <%= @post.user.profile.name %> but that obviously didn’t work.

This is the association defined in my models:

class User < ActiveRecord::Base
  has_many :posts
  has_one :profile
end

class Post < ActiveRecord::Base
  belongs_to :user
end

class Profile < ActiveRecord::Base
  belongs_to :user
end

This is the code in the view: <%= @post.user.profile.name %>

The error is undefined method profile

Answer 1

you have to mention the following in your models
user.rb

has_many :posts
has_one :profile

profile.rb

belongs_to :user

post.rb

belongs_to :user

Then <%= @post.user.profile.name %> should work.

And if still there is a problem in your data
