没有路由匹配 [PATCH] "/contact.1"; [英] No route matches [PATCH] "/contact.1"

问题描述

我是 Rails 新手，正在努力解决 Rails 4.2.3 应用程序中提到的错误.更新资源时出现此错误:

I am new to rails and struggling with the mentioned error in Rails 4.2.3 application. I am getting this error while updating a resource:

No route matches [PATCH] "/contact.1"

这是我的应用程序代码片段:

Here is my application code snippets:

routes.rb

resources :contacts

models/contact.rb

class Contact < ActiveRecord::Base
  belongs_to :user
  validates :name,  presence: true, length: { maximum: 50 }
  validates :number, presence:true
end

views/contacts/edit.html.erb

<h1> Editing Contact </h1>

<%= form_for @contact do |f| %>
    <%= f.label :name %><br>
    <%= f.text_field :name %><br>

    <%= f.label :number %><br>
    <%= f.text_field :number%><br><br>

    <%= f.submit "Update Contact", class: "btn btn-primary" %>
<% end %>

controllers/contacts_controller.rb

def edit
    @contact = Contact.find(params[:id])
end

def update
    @contact = Contact.find(params[:id])
    if @contact.update(contact_params)
        flash[:success] = "Contact Update Successfully..."
        redirect_to contacts_url
    else
        render 'edit'
    end
end

令人惊讶的是，路径生成为 /contact.1 而不是 /contact/1.

Surprisingly the path being generated as /contact.1 instead of /contact/1.

我也尝试将 url: contact_path(@contact), method: :patch 添加到 form_for 但没有运气.

I also tried by adding url: contact_path(@contact), method: :patch to form_for but no luck.

谁能告诉我代码有什么问题?

Can anybody tell me what is wrong with the code?

推荐答案

在您的控制器中，尝试将您的 redirect_to 从redirect_to contacts_url"更改为redirect_to contacts_path".在您的控制器中，您应该使用路径而不是 url.所以你的代码会是这样的:

In your controller, try changing your redirect_to from "redirect_to contacts_url" to "redirect_to contacts_path". Inside your controller you should use path instead of url. So your code will be like this:

 def update
     @contact = Contact.find(params[:id])
     if @contact.update(contact_params)
         flash[:success] = "Contact Update Successfully..."
         redirect_to contacts_path
     else
         render 'edit'
     end
 end
