Question

models:

#StatusMessage model
class StatusMessage < ActiveRecord::Base
  belongs_to :users
  default_scope :order => "created_at DESC"
end


#User Model
class User < ActiveRecord::Base
  has_many :status_messages 
end

In controller I want to join these two tables and get fields from both table. for example I want email field from User and status field from StatusMessage. When I use :

@status = User.joins(:status_messages)

Or

@status = User.includes(:status_messages)

It gives me only the user table data.

How can I implement this requirement?

Answer 1

You need to use includes here. It preloads data so you won’t have another SQL query when you do @user.status_messages.

And yes you can’t really see the effect: you need to check your logs.
