问题


I'm having a time trying to get this nested model working. I've tried all manner of pluralization/singular, removing the attr_accessible altogether, and who knows what else.

restaurant.rb:

# == RESTAURANT MODEL
#
# Table name: restaurants
#
#  id         :integer          not null, primary key
#  name       :string(255)
#  created_at :datetime         not null
#  updated_at :datetime         not null
#

class Restaurant < ActiveRecord::Base
  attr_accessible :name, :job_attributes

  has_many    :jobs
  has_many    :users, :through => :jobs
  has_many    :positions

  accepts_nested_attributes_for :jobs, :allow_destroy => true

  validates :name, presence: true

end

job.rb:

# == JOB MODEL
#
# Table name: jobs
#
#  id            :integer          not null, primary key
#  restaurant_id :integer
#  shortname     :string(255)
#  user_id       :integer
#  created_at    :datetime         not null
#  updated_at    :datetime         not null
#

class Job < ActiveRecord::Base
  attr_accessible :restaurant_id, :shortname, :user_id

  belongs_to    :user
  belongs_to    :restaurant
  has_many      :shifts


  validates :name, presence: false

end

restaurants_controller.rb:

class RestaurantsController < ApplicationController

  before_filter :logged_in, only:  [:new_restaurant]

  def new
    @restaurant = Restaurant.new
    @user = current_user
  end

  def create
    @restaurant = Restaurant.new(params[:restaurant])
    if @restaurant.save
      flash[:success] = "Restaurant created."  
      redirect_to welcome_path
    end
  end

end

new.html.erb:

<% provide(:title, 'Restaurant') %>

  <%= form_for @restaurant do |f| %>
        <%= render 'shared/error_messages' %>

        <%= f.label "Restaurant Name" %>
        <%= f.text_field :name %>

        <%= f.fields_for :job do |child_f| %>

              <%= child_f.label "Nickname" %>
              <%= child_f.text_field :shortname %>

        <% end %>

        <%= f.submit "Done", class: "btn btn-large btn-primary" %>

  <% end %>

Output Parameters:

{"utf8"=>"✓",
 "authenticity_token"=>"DjYvwkJeUhO06ds7bqshHsctS1M/Dth08rLlP2yQ7O0=",
 "restaurant"=>{"name"=>"The Pink Door",
 "job"=>{"shortname"=>"PD"}},
 "commit"=>"Done"}

The error i'm receiving is:

ActiveModel::MassAssignmentSecurity::Error in RestaurantsController#create

Cant mass-assign protected attributes: job
Rails.root: /home/johnnyfive/Dropbox/Projects/sa

Application Trace | Framework Trace | Full Trace
app/controllers/restaurants_controller.rb:11:in `new'
app/controllers/restaurants_controller.rb:11:in `create'

Anyone have ANY clue how to get this to work? Thanks!


回答1:


in restaurant.rb:

it should be attr_accessible :name, :jobs_attributes instead of attr_accessible :name, :job_attributes




回答2:


regarding your last comment: you can submit the user_id within your job form, that should submit the user_id to the model
