ネストされたリソースを持つシードDB：シンボルの整数への暗黙的な変換なし

Question

私はプロジェクトを壊したと思います。 :(私は数多くの変更を加えましたが、そのうちの1つはリソースを入れ替えて入れ子にしていました（浅い：真）。私はDBをもう一度シードしようとしていて、TypeErrorを取得しています。 。私はStackOverflowの通過見てきたし、一人は、同様の問題が、ノーの答えを持っていた私は、インターネット上の他の場所に動作します答えを見つけることができます

マイroutesファイル：

Goalie::Application.routes.draw do 


    resources :users, shallow: true do 
    resources :goals 
    resources :steps 
    resources :habits 
    end 

マイスキーマルックスを。

ActiveRecord::Schema.define(:version => 20161121101351) do 

    create_table "users", :force => true do |t| 
    t.integer "user_id" 
    t.string "firstname" 
    t.string "lastname" 
    t.string "username" 
    t.string "password" 
    t.string "userEmail" 
    t.datetime "created_at", :null => false 
    t.datetime "updated_at", :null => false 
    end 


    create_table "goals", :force => true do |t| 
    t.integer "goal_id" 
    t.string "name" 
    t.string "description" 
    t.date  "deadline" 
    t.boolean "completed" 
    t.datetime "created_at", :null => false 
    t.datetime "updated_at", :null => false 
    end 

    create_table "steps", :force => true do |t| 
    t.integer "step_id" 
    t.string "name" 
    t.string "description" 
    t.boolean "completed" 
    t.datetime "created_at", :null => false 
    t.datetime "updated_at", :null => false 
    end 


    create_table "habits", :force => true do |t| 
    t.integer "habit_id" 
    t.string "name" 
    t.string "description" 
    t.boolean "frequency" 
    t.integer "frequencytime" 
    t.datetime "created_at", :null => false 
    t.datetime "updated_at", :null => false 
    end 
end 

seed.rbファイルは次のようになります。

params = { :user => 
    { 
    :user_id => '1', 
    :firstname => 'Salaman', 
    :lastname=> 'Rushdie', 
    :username=> 'bigboss', 
    :password=> 'admin', 
    :userEmail=> 'bigboss@hotmail.com', 
    :goals_attributes => { 
     :goal_id => '1', 
     :name => 'Lose weight', 
     :description => 'Lose 30lb', 
     :deadline => '25/12/2016', 
     :completed => false, 
     :steps_attributes => { 
      :step_id => '1', 
      :name => 'Work out', 
      :description => 'Exercise to achieve weight loss goal', 
      :completed => false, 
       :habits_attributes => { 
       :habit_id => '1', 
       :name => 'Gym', 
       :description => 'Go to the gym 5 times a week', 
       :frequency => 'true', 
       :frequencytime => '5', 
       } 
      } 
     } 
    } 
} 
User.create!(params[:user]) 

そして、私はDBをシードしようとすると、私はこのメッセージが表示されます。

この回答を参照してください：

Rails3 seed data nested attribute

ここでは重要な部分です：

If you are wanting to try and use the nested attributes way, then you don't need the :vendor => {} part of the hash, you can go straight into the params, and you need addresses_attributes to be an array, not a hash.
