ruby-on-rails - 路由错误未初始化常量 ContactFormsController

Question

我正在尝试制作我的第一个 Rails 应用程序，但遇到了路由问题。我的 routes.rb 是:

Rails.application.routes.draw do
  resources :users
  resources :sessions, only: [:new, :create, :destroy]
  resources :contact_forms, only: [:new, :create, :destroy]
  root 'static_pages#home'
  match '/',        to: 'static_pages#home',       via: 'post'
  match '/manager', to: 'static_pages#manager',    via: 'get'
  match '/manager', to: 'sessions#create',         via: 'post'
  match '/signin',  to: 'sessions#new',            via: 'get'
  match '/signout', to: 'sessions#destroy',        via: 'delete'
end

我的 contact_form_controller.rb 是:

class ContactFormController < ApplicationController

  def new
    @contact_form = ContactForm.new
  end

 def create
    @contact_form = ContactForm.new message_params
    @contact_form.save
    redirect_to root_path, notice: "Saved"
 end

  private
    def contact_form_params
      params.require(:contact_form).permit(:name, :phone, :email, :text)
    end
end

我的 new.html.erb 文件是:

<%= form_for @contact_form do |f| %>
   <%= f.text_field :name %>
   <%= f.text_field :phone %>
   <%= f.text_field :email %>
   <%= f.text_field :text %>
   <%= f.submit %>
<% end %>

怎么了？谢谢

uninitialized constant ContactFormsController

您应该将 Controller 类名从ContactFormController更改为ContactFormsController，并将文件名更改为 contact_forms_controller.rb

此外，在您的代码中，您需要在 create 中将 @contact_form = ContactForm.new message_params 更改为 @contact_form = ContactForm.new contact_form_params避免任何进一步问题的方法。

此外，当您尝试创建您的第一个应用程序时，我建议您遵循这些 Guides
