Creating New Statuses in Treebook

As seen in the video "Creating Relationships" (Programming >Build a Simple Ruby on Rails Application >Customizing Forms >Creating Relationships), the error 

"ActiveModel::MassAssignmentSecurity::Error in StatusesController#create

Can't mass-assign protected attributes: user_id"

is shown when creating a new status. When the problem is fixed in the video by adding ":user_id" to "status.rb", this doesn't work for me. After I save everything out, I still get that error. What can I do to fix this?

Also, I noticed that I get the error message: "Can't mass-assign protected attributes: user"

However, the video is: "Can't mass-assign protected attributes: user_id"

Not sure if that is a problem or not.

In your Status model have you added :user_id to the attr_accessible list?

Also, have you set your belongs_to and has_many associations between your User and Status models?

Yes, I've done both of those. My code for the Status Model is:

attr_accessible :content, :user_id
belongs_to :user

and my code for the User Model is 

has_many :statuses
  def full_name
   first_name + " " + last_name
  end

Hey William do you have a :user_id within your status table? Check db/ migrate/schema.rb folder) it should look like below.. 

 create_table "statuses", :force => true do |t|
   t.text     "content"
   t.datetime "created_at", :null => false
   t.datetime "updated_at", :null => false
   t.integer  "user_id"
 end

  add_index "statuses", ["user_id"], :name => "index_statuses_on_user_id"

Daniel, thanks for the input. I did not have that, but that still did not work for me. Also, was that in any of the videos?

Hey William watch and follow this video.. This should fix your problem... You can't just added :user_id and save it you have to create and Database migration... The video should explain all this.. Let me know how it goes..
