  belongs_to :author, :class_name => "AdminUser"


  validates_presence_of :body,:title
  scope :published, where(:published => true)

  def content
    MarkdownService.new.render(body)
  end

  def author_name
    if author
      author.name
    else
      "Nobody"
    end
  end


end

Rails4 uses strong parameters rather than attr_accessibles.

You'll need to use Strong Params for this:

#app/models/post.rb
class Post < ActiveRecord::Base
  has_many :comments
  belongs_to :author, :class_name => "AdminUser"

  validates_presence_of :body,:title
  scope :published, where(:published => true)

  def content
    MarkdownService.new.render(body)
  end

  def author_name
    if author
      author.name
    else
      "Nobody"
    end
  end


end

#app/controllers/posts_controller.rb
def new
    @post = Post.new
end

def create
    @post = Post.new(post_params)
end

private

def post_params
    params.require(:post).permit(:body, :title, :published, :author, :author_id)
end

` def create @post = Post.new(post_params) respond_to do |format| if @post.save format.html { redirect_to @post, notice: 'Post was successfully created.' } format.json { render action: 'show', status: :created, location: @post } else format.html { render action: 'new' } format.json { render json: @post.errors, status: :unprocessable_entity } end end end ` create method – Murat KAYA Mar 26 '14 at 21:56
