Ruby on Rails：没有路线匹配 [POST] '/contacts/new'

Question

Rails 5. 不断收到找不到路线的错误。我在这里做错了什么？

App/views/contacts/new.html.erb

<%= form_for "@contact" do |f| %>
                <div class="form-group">
                    <%= f.label :name %>
                    <%= f.text_field :name, class: 'form-control' %>
                </div>

                <div class="form-group">
                    <%= f.label :email %>
                    <%= f.text_field :email, class: 'form-control'  %>
                </div>

                <div class="form-group">
                    <%= f.label :comments %>
                    <%= f.text_area :comments, class: 'form-control' %>
                </div> 

                <%= f.submit 'Submit', class: 'btn btn-default' %>

     <% end %>

routes.rb 文件

Rails.application.routes.draw do
root to: 'pages#home'
get '/about', to: 'pages#about'
resources :contacts
end

contacts_controller.rb

class ContactsController < ApplicationController
def new
    @contact = Contact.new
end

def create
    @contact = Contact.new(contact_params)
    if @contact.save
        redirect_to new_contact_path, notice: "Message sent."
    else
        redirect_to new_contact_path, notice: "Error occured."
    end
end

private
    def contact_params
        params.require(:contact).permit(:name, :email, :comments)
    end

结束

contact.rb（模型文件，暂时空白）

class Contact < ActiveRecord::Base
end

我不知道为什么。提前致谢。

您的表单中的@contact 变量有引号，请尝试使用普通的@contact 变量。
