Как вставить данные в таблице соединения на основе HABTM ассоциации рельсы 4

Question

Я создал HABTM ассоциацию НПЗ СХ, но она возвращает ошибку, как показано ниже:

ActiveRecord::StatementInvalid: PG::UndefinedTable: ERROR: relation "refinery_georgiantoast_restaurant_wines" does not exist 
LINE 5:    WHERE a.attrelid = '"refinery_georgiantoast_r... 
             ^
:    SELECT a.attname, format_type(a.atttypid, a.atttypmod), 
        pg_get_expr(d.adbin, d.adrelid), a.attnotnull, a.atttypid, a.atttypmod 
       FROM pg_attribute a LEFT JOIN pg_attrdef d 
        ON a.attrelid = d.adrelid AND a.attnum = d.adnum 
       WHERE a.attrelid = '"refinery_georgiantoast_restaurant_wines"'::regclass 
       AND a.attnum > 0 AND NOT a.attisdropped 
       ORDER BY a.attnum

Вот мой restaurant.rb модель:

module Refinery 
    module Georgiantoast 
    class Restaurant < Refinery::Core::BaseModel 

     validates :title, :presence => true, :uniqueness => true 

     belongs_to :avatars, :class_name => '::Refinery::Image' 

     has_many :restaurants_wines 

     has_many :wines, :through => :restaurants_wines 

     # To enable admin searching, add acts_as_indexed on searchable fields, for example: 
     # 
     # acts_as_indexed :fields => [:title] 

    end 
    end 
end 

/vendor/extensions/georgiantoasts/app/models/refinery/georgiantoast/wine.rb

Вот мой wine.rb модель:

module Refinery 
    module Georgiantoast 
    class Wine < Refinery::Core::BaseModel 

     validates :title, :presence => true, :uniqueness => true 

     belongs_to :avatars, :class_name => '::Refinery::Image' 

     has_many :restaurants_wines 

     has_many :restaurants, :through => :restaurants_wines 

     # To enable admin searching, add acts_as_indexed on searchable fields, for example: 
     # 
     # acts_as_indexed :fields => [:title] 

    end 
    end 
end 

/поставщик/расширения/georgiantoasts/приложение/модели/НПЗ/georgiantoast/restaurant_wines.rb

Вот мой присоединиться табличная модель restaurant_wines.rb

module Refinery 
    module Georgiantoast 
    class RestaurantWine < Refinery::Core::BaseModel 

     belongs_to :wine 

     belongs_to :restaurant 

     # To enable admin searching, add acts_as_indexed on searchable fields, for example: 
     # 
     # acts_as_indexed :fields => [:title] 

    end 
    end 
end 

/vendor/extensions/georgiantoasts/app/controllers/refinery/georgiantoast/admin/restaurants_controller.rb

Здесь restaurants_controller.rb Контроллер:

module Refinery 
    module Georgiantoast 
    module Admin 
     class RestaurantsController < ::Refinery::AdminController 

     crudify :'refinery/georgiantoast/restaurant' 

     private 

     # Only allow a trusted parameter "white list" through. 
     def restaurant_params 
      params.require(:restaurant).permit(:title, :description, :address, :town, :state, :lat, :lng, :avatars_id, :wine_ids => []) 
     end 
     end 
    end 
    end 
end 

/поставщики/расширения/georgiantoasts/app/views/refinery/georgiantoast/admin/restaurants/_form.html.erb

Вот ресторан _form.html.erb формы:

<%= form_for [refinery, :georgiantoast_admin, @restaurant] do |f| -%> 
    <%= render '/refinery/admin/error_messages', 
       :object => @restaurant, 
       :include_object_name => true %> 

    <div class='field'> 
     <%= f.label :title -%> 
     <%= f.text_field :title, :class => 'larger widest' -%> 
    </div> 

    <div class='field'> 
     <%= render '/refinery/admin/wysiwyg', 
       :f => f, 
       :fields => [:description], 
       :object => "georgiantoast/restaurant" -%> 
    </div> 

    <div class='field'> 
     <%= f.label :address -%> 
     <%= f.text_field :address -%> 
    </div> 

    <div class='field'> 
     <%= f.label :wine -%> 
     <%= select_tag "#{f.object_name}[wine_ids][]", options_for_select(Refinery::Georgiantoast::Wine.all.collect { |wine| [wine.title, wine.id] }), {multiple: true} -%> 
    </div> 


    <%= render '/refinery/admin/form_actions', :f => f, 
       :continue_editing => false, 
       :delete_title => t('delete', :scope => 'refinery.restaurants.admin.restaurants.restaurant'), 
       :delete_confirmation => t('message', :scope => 'refinery.admin.delete', :title => @restaurant.title) -%> 
<% end -%> 

Вот файл миграция:

class CreateJoinTableRestaurantsWines < ActiveRecord::Migration 
    def change 
    create_join_table :restaurants, :wines do |t| 
     t.index :restaurant_id 
     t.index :wine_id 
    end 
    end 
end 

Когда я отправляю свою форму она не выполняет никаких действий в вызове присоединиться к таблице ,

Если я пытаюсь запустить следующую команду на rails console она возвращает меня под ошибкой:

Все миграции уже бежал, не миграции или семя не находится на рассмотрении тоже.

Answer 1

Если вы используете form_for вы можете использовать эту приведенную ниже на ваш взгляд приложение/просмотров/рестораны/_form

<%= f.collection_select :wine_ids, @wines, :id, :name, {}, {:multiple => true} %> 

Не забывайте об этом в контроллере

params.require(:restaurant).permit(:name, :wine_ids => []) 

Answer 2

Вы появляетесь иметь опечатка в винных и ресторанных классах.Отношение должно быть через restaurant_wines, а не restaurants_wines (так что только «вино» должно быть множественным).

Вам нужно добавить wine_id и restaurant_id столбцы в таблицу соединений, если вы еще этого не сделали. После того, как они там, вы должны быть
