嵌套資源破壞行動

Question

我試着添加摧毀我的嵌套資源按鈕，收到此錯誤：No route matches [DELETE] "https://stackoverflow.com/users/1/2/4/5/holidays/7"

繼承人的我看來，路線，車型的相關部分，&控制器：

<% @user.holidays.each do |h| %> 
    <td><%= h.name %></td> 
    <td><%= h.date %></td> 
    <td> 
    <%= button_to('Destroy', user_holiday_path(@user.holidays), :method => 'delete', :class => 'btn btn-large btn-primary') %> 
    </td> 
<% end %> 

路線

resources :users do 
    resources :interests 
    resources :holidays 
end 

模型

class User < ActiveRecord::Base 
    has_many :holidays, :through => :user_holidays 
end 

class UserHoliday < ActiveRecord::Base 
    attr_accessible :holiday_id, :user_id 
    belongs_to :user 
    belongs_to :holiday 
end 

class Holiday < ActiveRecord::Base 
    attr_accessible :name, :date 
    has_many :user_holidays 
    has_many :users, :through => :user_holidays 

end 

控制器

class HolidaysController < ApplicationController 
    def index 
    @user_holidays = Holiday.find(params[:user_id]) 
    @holidays = @user_holidays.holidays 
    end 

    def new 
    end 

    def show 
    @holiday = Holiday.find(params[:id]) 

    respond_to do |format| 
     format.html # show.html.erb 
     format.json { render json: @holiday } 
    end 
    end 

    def destroy 
    @holiday = Holiday.find(params[:id]) 
    @holiday.destroy 
    end 
end 

謝謝！

Answer 1

更改此：
<%= button_to('Destroy', user_holiday_path(@user.holidays), :method => 'delete', :class => 'btn btn-large btn-primary') %>
這樣：
<%= button_to('Destroy', user_holiday_path(h), :method => 'delete', :class => 'btn btn-large btn-primary') %>

更新

更改破壞行動來自：
@holiday = Holiday.find(params[:id])到
@user_holiday = UserHoliday.find(params[:id])

，並在您的視圖：
變化
<% @user.holidays.each do |h| %> 到

<% @user.user_holidays.each do |h| %>

你的協會需要一定的修正，應該是如下：
user has_many user_holidays
user_holiday has_one holiday
user_holidays belongs_to user

您可以通過您的H訪問對象的姓名和假期：
h.holiday.name
h.holiday.date
