Question

I am very new to Ruby on Rails and I was following the Railstutorial to make a demo app using Scaffold.

First when I added the User model using scaffold, it worked fine. Then, when I added the micropost model, I kept getting the following error:

/demo_app/app/models/micropost.rb:4: syntax error, unexpected ':', expecting keyword_end
  belongs_to: user

I noticed that the code generated by scaffold did not generate the same code as shown in the tutorial. Here is the User and Microposts model :

class User < ActiveRecord::Base
  attr_accessible :email, :name
  has_many :microposts
end

class Micropost < ActiveRecord::Base
  attr_accessible :content, :user_id

  belongs_to: user

  validates :content, :length => { :maximum => 140 }
end

The attr_accessible line is not there in the tutorial. what is this exactly and is this the problem?
I have run the Rake program and everything else that was mentioned.

Answer 1

It should be belongs_to :user. You better use some texteditor with highlight for rails
