NoMethodError在StaticPagesController＃email_contact，軌道4,5

Question

我試圖做一個接觸的形式爲我的應用程序，但我得到一個錯誤：undefined method 'send_email' for ProductMailer:Class.

我Staticpagescontroller是：

def email_contact 
    ProductMailer.send_email().deliver 
    redirect_to contact_url 
end 

我的電子郵件使用者是：

class Contact < ActionMailer::Base 
default from: "from@example.com" 

# Subject can be set in your I18n file at config/locales/en.yml 
# with the following lookup: 
# 
# en.contact.send_email.subject 
# 

def send_email 
    @greeting = "Hi" 

    mail to: "example@example.com" 
end 
end 

我的路線是：

match '/show/:id', to: 'stores#show', via: 'get', :as=> 'show' 
get "emailproduct/:id" => "products#email_product", :as => "email_product" 
get "emailcontact" => "static_pages#email_contact", :as => "email_contact" 

Answer 1

只需重命名你的class Contact < ActionMailer::Base到class ProductMailer < ActionMailer::Base

Answer 2

重命名類聯繫到ProductMailer

Answer 3

您已經指定了錯誤的類名。在你的郵件類中，你已經定義了Contact類，但是你在控制器動作中使用了ProductMailer。它應該是：

def email_contact 
    Contact.send_email().deliver 
    redirect_to contact_url 
end
