我正在构建一个Rails应用程序的联系表单，并收到以下错误：
'The action 'index' could not be found for ContactsController'
我很困惑，因为我之前已经建立了联系表格，同样的方式也毫无问题。这看起来很奇怪，因为我根本没有在ContactsController中使用或引用index.html.erb或index方法？请找到以下文件：
contacts_controller.rb
class ContactsController < ApplicationController
def new
@contact = Contact.new
end
def create
@contact = Contact.new(contact_params)
if @contact.save
flash[:success] = "Message Sent!"
redirect_to new_contact_path
else
flash[:danger] = "Error occurred"
redirect_to new_contact_path
end
end
private
def contact_params
params.require(:contact).permit(:name, :phone, :email, :comments)
end
end
模型/ contact.rb
class Contact < ActiveRecord::Base
validates :name, presence: true
validates :email, presence: true
after_create :send_email
private
def send_email
ContactMailer.contact_email(self).deliver
end
end
寄件人/ contact_mailer.rb
class ContactMailer < ActionMailer::Base
default to: 'example@example.com.au'
def contact_email(contact)
@contact = contact
mail(from: @contact.email, subject: 'Contact Form Message').deliver
end
end

答案 0 :(得分：4)
如果您正在使用资源。您应该在控制器中执行所有这些操作。
GET /photos photos#index display a list of all photos
GET /photos/new photos#new return an HTML form for creating a new photo
POST /photos photos#create create a new photo
GET /photos/:id photos#show display a specific photo
GET /photos/:id/edit photos#edit return an HTML form for editing a photo
PATCH/PUT /photos/:id photos#update update a specific photo
DELETE /photos/:id photos#destroy delete a specific photo
而不是路线中的resources :contacts。使用
resources :contacts, only: [:create,:new]
或
resources :contacts, except: [:index]
在上面指定了我给出的示例路由中所需的方法。
在resources :contacts, only: [:create,:new]中的第一个中，您的控制器中应该只有两个动作。
GET /photos/new photos#new return an HTML form for creating a new photo
POST /photos photos#create create a new photo
如果您不想限制路线。请在控制器中指定操作：
对于你的控制器中的index动作就像这样。这也很有效。
def index
