Question

我之前从未遇到过这个问题。我收到了这个错误。

No route matches [GET] "/recipes/1/like"

这是我的routes.rb：

Rails.application.routes.draw do

  root 'pages#home'

  get '/home', to: "pages#home"

  resources :recipes do
    member do
      post 'like'
    end
  end
end

这是我的recipes_controller：

  def like
    @recipe = Recipe.create(params[:id])
    Like.create(like: params[:like], chef: Chef.first, recipe: @recipe)
    #flash message
    flash[:success] = "Your selection was sucessful"
    redirect_to :back
  end

这是我的html.erb文件：

<%= render 'shared/page_title', title: @recipe.name.titleize  %>

<div class= "row">
  <div class="col-md-4 pull-right center">
    <%= gravator_for @recipe.chef, size: 200 %>
    <p>
      <h5>Brought to you by: <%= @recipe.chef.chefname.capitalize %></h5>
    </p>
  </div>
  <div class= "col-xs-8 col-md-8">
    <%= link_to "Edit this Recipe", edit_recipe_path(@recipe), class: "btn btn-success pull-right" %>
    <h3><%= @recipe.summary.capitalize %></h3>
    <div class="show_recipe">
      <%= image_tag(@recipe.picture.url, size: "300x200", class: "recipe-image") if @recipe.picture? %>
    </div>
    <div class ="well recipe-description">
      <p>
        <strong> Steps:</strong>
      </p>
        <%= simple_format(@recipe.description) %>
        <div class="pull-right">
          <%= link_to like_recipe_path(@recipe, like: true), method: :post do %>
            <i class="glyphicon glyphicon-thumbs-up"></i>
          <% end %> &nbsp&nbsp&nbsp&nbsp
          <%= link_to like_recipe_path(@recipe, like: false), :method => :post do %>
            <i class="glyphicon glyphicon-thumbs-down"></i>
          <% end %>
        </div>
    </div>
  </div>
</div>

<h5><%= link_to "Return to Recipes Listings", recipes_path, class: "btn btn-warning btn-small" %></h5>

我已将HTTP POST请求明确添加到我的html.erb文件

%= link_to like_recipe_path(@recipe, like: true), method: :post do %>

但是rails抱怨没有GET路由请求，我从未在路由中创建过，因为我需要对Web应用程序的这个特定部分发出POST请求。

耙路线：

     Prefix Verb   URI Pattern                 Controller#Action
       root GET    /                           pages#home
       home GET    /home(.:format)             pages#home
like_recipe POST   /recipes/:id/like(.:format) recipes#like
    recipes GET    /recipes(.:format)          recipes#index
            POST   /recipes(.:format)          recipes#create
 new_recipe GET    /recipes/new(.:format)      recipes#new
edit_recipe GET    /recipes/:id/edit(.:format) recipes#edit
     recipe GET    /recipes/:id(.:format)      recipes#show
            PATCH  /recipes/:id(.:format)      recipes#update
            PUT    /recipes/:id(.:format)      recipes#update
            DELETE /recipes/:id(.:format)      recipes#destroy

我老实说丢了。似乎一切都在正确的位置。

Rails版本：

Rails 4.2.5

我已经定义了操作，创建了类似的模型，在配方下嵌套了路由，并在html.erb页面中显式请求了后HTTP请求。

任何想法都会很棒！

干杯！

这是我工作项目中的相关代码，具有类似的安排。

Tanswer=float(raw_input("Enter The Tangent:"))

Answer 2

尝试

<%= link_to "LIKE", like_recipe_path(@recipe) ,  method: :post %>

其他选择：

<%= link_to '<i class="glyphicon glyphicon-thumbs-up"></i>'.html_safe , like_recipe_path(@recipe ,  like: 'value' ) ,  method: :post %>

Answer 3

虽然rails link_to允许链接使用GET以外的方法发出请求，但这不是链接的正常行为，而是依赖于Javascript来制作在幕后提交的表单。 Rails使用jquery-ujs为此，所以请确保您没有禁用它。

也就是说，POST请求是表单的正常行为，因此您也可以尝试使用button_to，只需将按钮样式设置为链接即可必要的。

<%= button_to "Like",  like_recipe_path(@recipe), method: :delete, like: true  %>

Answer 4

您需要添加GET路线：

resources :recipes do
    member do
      get 'like'
      post 'like'
    end
  end

没有路线匹配[GET]＆＃34; / recipes / 1 / like＆＃34;我想要一个POST请求
