Restful 使用带有复选框选项的表单路由嵌套资源

Restful Routing for Nested Resource with a Form with Checkbox Options

我的模型是:

class User < ApplicationRecord
  has_many :user_stores
  has_many :stores, through: :user_stores        
end

class UserStore < ApplicationRecord
  belongs_to :user
  belongs_to :store
end

class Store < ApplicationRecord
  has_many :user_stores
  has_many :users, through: :user_stores
end

我的路线:

Rails.application.routes.draw do
  devise_for :users

  root 'home#index'

  resources :user do
    resources :stores
  end
end

在我的加入table中,我要记录用户最喜欢的店铺,用户想收藏的店铺。这将通过带有复选框的表单来完成,并且用户已经喜欢的商店将被选中。

我有两条路让我很困惑。当用户单击按钮转到页面以查看其最喜欢的商店时,它应该转到:

1./user/:user_id/stores(.:format) (如果我走这条路线,当提交表单时,它应该 Post 到路径 /user/:user_id/stores,然后在控制器中我将采用参数 store_ids[] 并遍历每个商店 ID,将其创建到数据库。)

还是应该去

2./user/:id(如果我转到我的表单当前执行的这条路线,我将不得不使用 Patch 到路径 /user/:id。在这一点上,因为我正在使用 Devise,我将不得不创建一个用户的控制器,并使用 store_ids 参数更新用户,同时循环 store_ids 以创建连接 table 条目)

我知道这可能是一个 multi-part 问题,但无论哪条路线更合适,我将如何布置表格以反映这一点?目前我有:

<%= simple_form_for(@user, html: { class: 'form-horizontal' }) do |f| %>
  <%= f.association :stores, as: :check_boxes, label: false %>
  <%= f.button :submit, "Update Favorite Stores", class: "btn btn-primary" %>
<% end %>

但这会转到用户控制器。

第一个合适。第二个是用户展示页面。

在您的表单助手中,您可以只使用集合 select(我不确定我是否使用了以下正确的语法):

<%= f.collection_select :user, :store_ids, Store.all.order(name: :asc), :id, :name, {}, { multiple: true, class: "form-control" } %>
