找不到 ChefsController#create 的模板，渲染头：no_content 已完成 204 无内容
这是 Rails 5 中的一个问题，有助于 API
我已经看过这篇文章和其他几篇文章，但我仍然被卡住了。 https://www.rubyplus.com/articles/2771-Rails-5-Basics-View-to-Model
这是我尝试调试的过程：
鉴于我正在运行本地服务器
并且我在 localhost:3000/signup
当我输入名称、电子邮件、密码和密码确认时
然后我希望创建一个新的厨师
相反，我收到 204 No Content 错误：

我以为我即将解决这个问题，但我没有。
我记得如果你没有正确关闭它，调试器会使你的服务器挂起。我以为这可能是我的问题，但事实并非如此。我重新启动了我的虚拟机并再次运行服务器并收到相同的错误。
我已将调试器放在 create 方法中，但我的服务器从未到达调试器。它被困在新方法上。
在我的本地视图中：local::3000/chefs/3
我的代码：
配置/路由.rb
Rails.application.routes.draw do
root 'pages#home'
get 'pages/home', to: 'pages#home'
resources :recipes
get '/signup', to: 'chefs#new'
resources :chefs, except: [:new]
end
应用程序/模型/chef.rb
class Chef < ApplicationRecord
has_many :recipes
validates :chefname, presence: true, length: { maximum: 30 }
VALID_EMAIL_REGEX = /\A([\w+\-].?)+@[a-z\d\-]+(\.[a-z]+)*\.[a-z]+\z/i
validates :email, presence: true, length: { maximum: 50 }, uniqueness: {case_sensitive: false},
format: { with: VALID_EMAIL_REGEX}
validates :password, presence: true, length: { minimum: 8 }
has_secure_password
end
应用程序/控制器/chefs_controller.rb
class ChefsController < ApplicationController
def index
@chefs = Chef.all
end
def new
@chef = Chef.new
end
def create
@chef = Chef.new(chef_params)
if @chef.save
flash[:success] = "Welcome #{@chef.chefname} to MyRecipes App!"
redirect_to chef_path(@chef)
else
render 'new'
end
end
def show
@chef = Chef.find(params[:id])
end
private
def chef_params
params.require(:chef).permit(:chefname, :email,
:password, :password_confirmation)
end
end
我添加了 index 和 show 方法只是为了确保有可用的模板。
