ProductsController中的NoMethodError＃email_product，Emailer rails 4

Question

我試圖爲「產品類」配置「Emailer」，但是我有一個錯誤，如：未定義的ProductMailer：Class的send_product方法。在這種情況下，我定義了這種方法。 這是我的電子郵件使用者等級：

class ProductMailer < 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.product_mailer.send_prodcut.subject 
# 
def send_prodcut 
@greeting = "Hi" 

mail to: "to@example.org" 
end 

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

end 

，這是我的ProductsController：

class ProductsController < ApplicationController 
before_filter :authenticate_authen! 
before_action :set_product, only: [:show, :edit, :update, :destroy] 

def email_product 
ProductMailer.send_product().deliver 
end 

，這是我的路線：

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

任何建議？由於

你有ProductMailer

你的方法定義一個錯字應

def send_product 
@greeting = "Hi" 

mail to: "to@example.org" 
end 

而不是

def send_prodcut 
@greeting = "Hi" 

mail to: "to@example.org" 
end
