RoR NoMethodError in Credits#new [SOLVED]

Hi, I am doing my homework around the building a simple RoR app and got stuck with the following:

I created a Scaffold called "Credit", and a relationship between the User and Credit model:

<strong>Here are my files</strong>
credit.rb

class Credit < ActiveRecord::Base
  attr_accessible :amount, :user_id
  belongs_to :user
  belongs_to :merchant

end

user.rb

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :remember_me,
                    :first_name, :last_name, :profile_name 

  # attr_accessible :title, :body
  has_many :statuses
  has_many :merchants
  has_many :credits

  def  full_name
    first_name + " " + last_name
  end
end

<strong>When trying to create a new credit entry with the following form:</strong>

<%= simple_form_for(@credit) do |f| %>
  <%= f.error_notification %>

  <div class="form-inputs">
    <%= f.input :amount %>
    <%= f.input :user_id, collection: User.all %>

  </div>


  <div class="form-actions">
    <%= f.button :submit %>
  </div>
<% end %>

<strong>I get the following error, </strong>

NoMethodError in Credits#new

Showing/Users/andreucasadella/rails_projects/monedero/app/view credits/_form.html.erb where line #6 raised:

undefined method `user_id' for #<Credit id: nil, amount: nil, created_at: nil, updated_at: nil>

<strong>Any idea?</strong>

Solution:

I was missing a db migration file. Now it works.

class AddUserIdtoCredit < ActiveRecord::Migration def change add_column :credits, :user_id, :integer end end –
