My userdetail/new.html.erb looks like

My userdetail controller looks like

#User can only edit or destroy its own details
before_action :correct_user, only: [:edit, :update, :destroy]

def correct_user
#user = #userdetail.user_id
redirect_to( userdetails_url) unless #user == current_user.id

end
My user detail model looks like
class Userdetail < ActiveRecord::Base
belongs_to :user
#validates that one user can create just one user details
validates_uniqueness_of :user_id, :message => "details already exist"
end
My db schema looks like

Please tell me answer. I generated app's view and model using command rails g scaffold userdetail but added 'myuserid' column later.Please see any if there is any other fault inn my code and suggest correction
Also my directory contain automatically generated duplicate files with ~ at the end of name, Any idea ?

Answer 1

I found the answer, when i ran rails console in heroku I found that myuserid column was not created in heroku. When i check my migration files I found that the migration file creating myuserid column was accidentally deleted. I recreated that file and my app start working.
