未初始化的常量Createcampaigns :: LikeController

Question

我一直在努力添加喜欢和喜欢的功能。我嵌套的路线，我无法弄清楚什么我做错了：

我的路线是这样的

createcampaign_like_index GET /createcampaigns/:createcampaign_id/like(.:format)    createcampaigns/like#index 
          POST /createcampaigns/:createcampaign_id/like(.:format)    createcampaigns/like#create 
    new_createcampaign_like GET /createcampaigns/:createcampaign_id/like/new(.:format)   createcampaigns/like#new 
    edit_createcampaign_like GET /createcampaigns/:createcampaign_id/like/:id/edit(.:format)  createcampaigns/like#edit 
     createcampaign_like GET /createcampaigns/:createcampaign_id/like/:id(.:format)   createcampaigns/like#show 
          PATCH /createcampaigns/:createcampaign_id/like/:id(.:format)   createcampaigns/like#update 
          PUT /createcampaigns/:createcampaign_id/like/:id(.:format)   createcampaigns/like#update 
          DELETE  /createcampaigns/:createcampaign_id/like/:id(.:format)   createcampaigns/like#destroy 



resources :createcampaigns do 
resources :like, module: :createcampaigns 

像控制器

app/controllers/createcampaigns/likes_controller.rb 

我喜欢Controller.rb的内容文件

class Createcampaigns::LikesController < ApplicationController 
before_action :authenticate_user! 

    def likes 

    end 

    def index 
    @createcampaign = Createcampaign.find(params[:createcampaign_id]) 
    @createcampaign.likes.where(user_id: current_user.id).first_or_create 
    respond_with(@createcampaign) 
    end 

    def create 
    @createcampaign.like.where(user_id: current_user.id).first_or_create 

    respond_to do |format| 
     format.html { redirect_to @createcampaign } 
     format.js 
    end 
    end 

    private 

    def set_post 
    @createcampaign = Createcampaign.find(params[:createcampaign_id]) 
    end 
end 

app/views/createcampaigns/show.html.erb

<div id="likes"> 
    <%= render partial: "likes" %> 
</div> 

用户模型

has_many :likes 

def likes?(post) 
    post.likes.where(user_id: id).any? 
end 

我第一次尝试用此作为链接：

<%= link_to "Like", createcampaign_like_path(@createcampaign), method: :like %> 

我得到这个错误

ActionController::UrlGenerationError in Createcampaigns#show 
    Showing /home/ubuntu/workspace/app/views/createcampaigns/_like.html.erb   where line #2 raised: 

    No route matches {:action=>"show", :controller=>"createcampaigns/like",  :createcampaign_id=>#<Createcampaign id: 127, name: "Sessions must go; special prosecutor must be appoi...", description: "Attorney General Jeff Sessions lied under oath abo...", image: nil, location: "35 windfield ave", reason: "During his confirmation hearing, when asked by Sen...", bio: nil, user_id: 18, policy_in_question: nil, time: nil, contact_info: nil, city: "jersey city", state: "nj", zipcode: "07521", address: "3", country: "USA", banner: nil, created_at: "2017-03-15 14:44:04", updated_at: "2017-03-16 12:24:10", campaign_image: nil, campaignimage: "americanflag.jpg", eventgroundrules: nil, starts_at: nil, start_time: "4pm", campaigndate: "2017-03-15", campaigntarget: 0, admin: true, category_name: nil, category_id: 6, president_id: 743, senatemember_id: 1819, housemember_id: 1408>, :id=>nil} missing required keys: [:id] 

提取的源（左右线＃2） ：

现在看来，这需要或缺少的属性，所以我试图通过在用户ID和

<%= link_to "Like", createcampaign_like_path(user_id: current_user.id), method: :like %> 

我得到这个：

No route matches {:action=>"show", :controller=>"createcampaigns/like", :id=>"127", :user_id=>16} missing required keys: [:createcampaign_id] 
Extracted source (around line #2): 
1 
2 
     <%= link_to "Like", createcampaign_like_path(user_id: current_user.id), method: :like %> 

我应该我的路线是什么？请帮忙..新建的轨道必须添加

Answer 1

您需要发布这条道路

<%= link_to "Like", createcampaign_like_index_path(@createcampaign), method: :post %> 

检查你想打造成行动

createcampaign_like_index GET /createcampaigns/:createcampaign_id/like(.:format)    createcampaigns/like#index 
          POST /createcampaigns/:createcampaign_id/like(.:format)    createcampaigns/like#create 

同样的路线，我觉得你有这样的事情

resources :like 

更改为
