我正在为 Rails 应用构建联系表单，但出现以下错误:
'The action 'index' could not be found for ContactsController'
我很困惑，因为我以前建立过联系表格，方式相同，没有问题。这似乎很奇怪，因为我根本没有在我的 ContactsController 中使用或引用 index.html.erb 或索引方法？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
邮寄者/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

最佳答案
如果您正在使用资源。您应该在 Controller 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
在你的 route 代替 resources :contacts。使用资源:联系人，仅:[:创建，:新]
或
资源:联系人，除了:[:index]
在上面的示例路由中指定您需要的方法。在 resources :contacts, only: [:create,:new] 中的第一个中，您的 Controller 中应该只有两个操作。
GET /photos/new photos#new return an HTML form for creating a new photo
POST /photos photos#create create a new photo
如果你不想限制你的路线。在 Controller 中指定 Action :对于 Controller 中的 index 操作就像这样。这也很有效。
def index
end
