Question

我搜索了很多，发现了类似的问题，但是任何看似合适，或者我都不理解。

我有3个型号，我选择一个型号的坏名称，即电视节目，你可能会将Show模型与show方法和视图混淆。

Show.rb

class Show < ActiveRecord::Base
    has_many :seasons
    belongs_to :user
    has_many :episodes , through: :seasons
    accepts_nested_attributes_for :seasons

    attr_accessible :name,:status,:duration
end

Season.rb

class Season < ActiveRecord::Base
    belongs_to :show
    has_many :episodes

    accepts_nested_attributes_for :episodes
    attr_accessible :order,:status
end

Episode.rb

class Episode < ActiveRecord::Base
    belongs_to :season
    attr_accessible :number
end

我为每个模型制作表格，我想做的是自动设置每个模型的外键。因此，在我的节目中，我想要创建一个将存储在该节目中的季节。

：显示/ show.html.erb

p id="notice"><%= notice %></p>
<% @seasons = Season.all %>
<% @episodes= Episode.all%>

<p>
  <strong>Name:</strong>
  <%= @show.name %>
</p>

<p>
  <strong>Status:</strong>
  <%= @show.status %>
</p>

<p>
  <strong>Episode Duration:</strong>
  <%= @show.Episode_Duration %>
</p>


    <% @seasons.where(:show_id => @show.id).each do |season| %>
      <tr>
        <td><%= season.order %></td>
        <td><%= season.status %></td>
        <h3>episodios</h3>
        <hr>
        <% @episodes.where(:season_id => season.id).each do |episode| %>
          <td> <%= episode.number%></td>
        <%end%>
        <hr>
        <td><%= link_to 'episode', episode_new_path(season.id)%></td>
      </tr>
      <br>
    <% end %>

    <h1><%=@show.id%></h1>
    <h1><%=@show.episodes.count%></h1>
    <h1></h1>




    **<%= link_to 'create seasons', season_new_path(@show.id)   %>**
<%= link_to 'Edit', edit_show_path(@show) %> |
<%= link_to 'Back', shows_path %>

在最后一行中，我传递了@ show.id来创建一个赛季，我希望使用@ show.id作为我的外键：show_id用于该赛季。我如何在我的参数中使用该ID？

我看了一些帖子，我试过这个，但是没有用，继承人控制器（只有我觉得有用的部分。）的 seasons_controller.rb

def create
    @season = Season.new(season_params)
    @season.show_id = params[:id]
    @season.save
    end
    respond_to do |format|
      if @season.save
        format.html { redirect_to @season, notice: 'Season was successfully created.' }
        format.json { render :show, status: :created, location: @season }
      else
        format.html { render :new }
        format.json { render json: @season.errors, status: :unprocessable_entity }

    end
  end

def season_params
      params.require(:season).permit(:order, :status)
    end

修改我的路线是：的的routes.rb

devise_for :users
  resources :episodes

  resources :seasons

  resources :shows
  root 'shows#index'
  get 'seasons/create/:id' => 'seasons#new', as: :season_new
  get 'episodes/create/:id' => 'episodes#new', as: :episode_new

  put 'subscribe_show/:id' => 'shows#subscribe', as: :user_subscribe_show
  put 'unsubscribe_show/:id' => 'shows#unsubscribe', as: :user_unsubscribe_show

  get 'user/dashboard/' => 'users#index', as: :user_dashboard

我的表格是：的季节/ form.html.erb

<%= form_for(@season) do |f| %>
  <% if @season.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@season.errors.count, "error") %> prohibited this season from being saved:</h2>

      <ul>
      <% @season.errors.full_messages.each do |message| %>
        <li><%= message %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

  <div class="field">
    <%= f.label :order %><br>
    <%= f.number_field :order %>
  </div>
  <div class="field">
    <%= f.label :status %><br>
    <%= f.text_field :status %>
  </div>
  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

显示/ form.html.erb

<%= form_for(@show) do |f| %>
  <% if @show.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@show.errors.count, "error") %> prohibited this show from being saved:</h2>

      <ul>
      <% @show.errors.full_messages.each do |message| %>
        <li><%= message %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

  <div class="field">
    <%= f.label :name %><br>
    <%= f.text_field :name %>
  </div>
  <div class="field">
    <%= f.label :status %><br>
    <%= f.text_field :status %>
  </div>
  <div class="field">
    <%= f.label :Episode_Duration %><br>
    <%= f.text_field :Episode_Duration %>
  </div>
  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

编辑2：的 schema.rb

create_table "episodes", force: :cascade do |t|
    t.integer  "number"
    t.integer  "season_id"
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
  end

  create_table "seasons", force: :cascade do |t|
    t.integer  "order"
    t.string   "status"
    t.integer  "show_id"
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.boolean  "watched"
  end

  create_table "shows", force: :cascade do |t|
    t.string   "name"
    t.string   "status"
    t.datetime "created_at",       null: false
    t.datetime "updated_at",       null: false
    t.integer  "Episode_Duration"
    t.integer  "user_id"
  end

迁移

class AddUserIdtoShow < ActiveRecord::Migration
  def change

    add_index  :shows , :user_id
  end
end

设置外键参数栏中的关系
