我正在运行 rails 5.0.2，并且一直在关注 https://gorails.com/episodes/liking-posts?autoplay=1 在我的产品展示页面上添加一个喜欢按钮。
我一生都无法弄清楚为什么我总是遇到错误
没有路由匹配 [GET] "/products/7199/like">
本教程的存储库位于此处 https://github.com/gorails-screencasts/gorails-24-liking-posts/blob/master/app/views/posts/_likes.html.erb
根据教程，我有一个像这样的 routes.rb，我在测试期间只添加了 [：create， :d estroy] 以尝试获取 post 请求。我什至在没有成员的情况下进行了测试。
Rails.application.routes.draw do
root to: "pages#home"
devise_for :users,
:path => '',
:path_names => {:sign_in => 'login', :sign_out => 'logout', :edit => 'profile'},
:controllers => {:omniauth_callbacks => 'omniauth_callbacks',
:registrations => 'registrations'
}
resources :users, only: [:show]
resources :vendors, only: [:show]
resources :brands, only: [:show]
resources :products do
resource :like, only: [:create,:destroy], module: :products
member do
get :toggle_status
end
end
resources :pages
# For details on the DSL available within this file, see http://guides.rubyonrails.org/routing.html
end
我的喜欢.rb模型是
class Like < ActiveRecord::Base
belongs_to :user
belongs_to :product
end
我的likes_controller嵌套在产品中。我在使用friendly_id时添加了@product.id，本教程使用产品ID。
class Products::LikesController < ApplicationController
respond_to :html, :js
before_action :authenticate_user!
before_action :set_product
def create
@product.likes.where(user_id: current_user.id).create!
respond_to do |format|
format.html { redirect_to @product.id}
format.js
end
end
def destroy
@product.likes.where(user_id: current_user.id).destroy_all
respond_to do |format|
format.html { redirect_to @product.id }
format.js
end
end
private
def set_product
@product = Product.find(params[:product_id])
end
end
我的按钮在我的产品显示页面上(我确实将它们放在部分(_likes.html.erb)中，但将它们移回进行测试)
<div id="product_<%= @product.id %>_likes" class="col-md-6">
<% if user_signed_in? && current_user.likes?(@product) %>
<%= link_to 'Unlike', product_like_path(@product.id), method: :delete, remote: true, class: 'btn btn-primary btn-lg btn-block' %>
<%- else -%>
<%= link_to 'Like', product_like_path(@product.id), method: :post, remote: true, class: 'btn btn-primary btn-lg btn-block' %>
<% end %>
</div>
并在视图/产品/喜欢中创建 create.js.erb 和 destroy.js.erb，如下所示
创造
$('#product_<%= @product.id %>_likes').html("<%=j render partial: 'products/likes', locals: {product: @product} %>");
摧毁
$('#product_<%= @product.id %>_likes').html("<%=j render partial: 'products/likes', locals: {product: @product} %>");
最初我以为我有一个涡轮链接问题(我仍然可能)，但注意到我没有点击帖子，尽管我的代码。 这是耙子
ake routes | grep like
product_like DELETE /products/:product_id/like(.:format) products/likes#destroy
POST /products/:product_id/like(.:format) products/likes#create
我的应用程序.js文件：
// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,
// or any plugin's vendor/assets/javascripts directory can be referenced here using a relative path.
//
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// compiled file. JavaScript code in this file should be added after the last require_* statement.
// jquery_ujs allows us to use 'data-remote',
// 'data-type', and 'data-method' attributes
//
//
// Read Sprockets README (https://github.com/rails/sprockets#sprockets-directives) for details
// about supported directives.
//= require jquery
//= require bootstrap-sprockets
//= require jquery_ujs
//= require jquery-ui
//= require jquery.turbolinks
//= require html.sortable
//= require turbolinks
//= require turbolinks-compatibility
//= require_tree .
$.turbo.use('turbolinks:load', 'turbolinks:request-start');
var resetForms = function () {
// this depends on your use
// this is for foundation 6's abide
$('form').each(function () {
$(this).foundation('destroy');
});
};
document.addEventListener("turbolinks:before-cache", function() {
resetForms();
});
我的javascript文件夹中有以下依赖项文件
application.coffee
cable.js
search.js
turbolinks-compatibility.coffee
search.coffee
loading.js
favorite_products.coffee
您可以给我任何指导来解决此问题，我们将不胜感激。
经过大量的拔头发，我发现最初的开发人员添加了一个application.coffee文件，该文件似乎只处理社交共享方面的事情。
我删除了有问题的文件。 其他一切都有效。包括涡轮链接问题。因此，从本质上讲，以上是您需要向产品模型添加类似系统的内容。
