content gets saved as nil rails

I have run into a rather unusual situation and I can't seem to figure out why this is happening:

I have a User model:

class User < ActiveRecord::Base
  has_many :posts, dependent: :destroy
end

And a Post model:

class Post < ActiveRecord::Base
  attr_accessor :content
  belongs_to :user
  default_scope{order('created_at DESC')}

  #validations
  validates(:content, presence: true, length: {maximum: 140})
  validates(:user_id, presence: true)
end

My migration for posts looks like this:

require_relative '20150405091935_create_posts'
class FixPosts < ActiveRecord::Migration
  def change
    revert CreatePosts #this was the original migration w/o a user reference

    create_table :posts do |t|
      t.belongs_to :user, index: true
      t.string :content
      t.integer :user_id

      t.timestamps null: false
    end
  end
end

The issue

I create a post

user = User.first
user.posts.create(content: "This is a post.")
=> true

However when I print it out I get the following:

#<Post:0x007fc1a0f1d628
  id: 1,
  user_id: 1,
  content: nil,
  created_at: Sun, 19 Apr 2015 19:45:38 UTC +00:00,
  updated_at: Sun, 19 Apr 2015 19:45:38 UTC +00:00>]

The content is lost and returns a nil.

What is going on here? Am I missing something?

Any help will be appreciated!Thank you for your time.

You should remove attr_accessor :content from your Post model as it sets content as virtual attribute – model attribute that is not persisted to the database .
