Cannot create new object for Ruby on Rails model

Question

simple question. I'm trying to create a new object for a very basic class

class Article < ActiveRecord::Base
  attr_accessor :title, :content

  validates :title,  :presence => true
  validates :content, :presence => true
end

However, when I try to create a new object in the console, the title and content fields always show up as nil

1.9.2-head :021 > a = Article.new(title: "abcdefg", content: "hijklmnop")
 => #<Article id: nil, title: nil, content: nil, created_at: nil, updated_at: nil>

Why can't I create a new object?

Try with Article.create!(title: "abcdefg", content: "hijklmnop") . The ! will display errors as to why the creating that object failed — prasvin

Were you trying to use attr_accessible?

@Jazear By using attr_accessor instead of attr_accessible you are over-riding the default rails setter/getter and hence the value you are setting in the constructor is ignored.

Correct, thanks. I guess now I need to create specific setter methods if I want to change the content of these objects

Alex Blakemore Over a year ago

Or better, delete the call to attr_accessor and use the generated setters and getters unless you have reason to do otherwise.
