如何在Rails中顯示買家名稱4-Action Mailer Views

Question

在買家購買了演出之後，我的應用程序中買家和賣家都會收到一封電子郵件，通知他們收件箱。 這是user_mailer.rb型號：我發送給買家

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

    def buyer(gig,email) 
    @gig = gig 
    @email = email 
    mail(to: @email, subject: 'box delivery') 
    end 

    def seller(gig,email) 
    @gig = gig 
    @email = email 
    mail(to: @email, subject: 'new box order') 
    end 
end 

現在我可以做的意見，在郵件模板。

1.@gig.user.name =它會顯示賣家名稱，誰擁有演出。如何顯示誰買了演出買家名稱：演出

問題的

2.@gig.title and @gig.description =說明和標題？我想這樣說：「親愛的buyer.name，賣方@ gig.user.name（這一個工程） 交付訂單。

千兆模式

has_many :purchases 
    has_many :buyers, through: :purchases 
    has_many :sellers, through: :purchases 
    belongs_to :user 

用戶模型

has_many :purchases, foreign_key: 'buyer_id' 
    has_many :gigs, through: :purchases, source: :buyer 
    has_many :gigs, dependent: :destroy 
    has_many :sales, foreign_key: 'seller_id', class_name: 'Purchase' 

採購模式

class Purchase < ActiveRecord::Base 
    belongs_to :gig 
    belongs_to :buyer, class_name: 'User' 
    belongs_to :seller, class_name: 'User' 
end 

千兆控制器

class GigsController < ApplicationController 
    def downloadpage 
    ActiveRecord::Base.transaction do 
     if current_user.points >= @gig.pointsneeded 
     @purchase = current_user.purchases.create(gig: @gig, seller: @gig.user) 
     if @purchase 
      current_user.points -= @gig.pointsneeded 
      @gig.user.points += @gig.pointsneeded 
      current_user.save 
      if @gig.user.save 
      UserMailer.buyer(@gig,current_user).deliver 
      UserMailer.seller(@gig,@gig.user.email, current_user.name).deliver 
      render 'successful_download', locals:{link:@gig.boxlink} 
      end 
     end 
     else 
     redirect_to :back, notice: "You don't have enough points,upload a box and start getting them." 
     end 
    end 
    end 
end 

Answer 1

這可能工作

def buyer(gig,user) 
    @gig = gig 
    @email = user.email 
    @name = user.name 
    mail(to: @email, subject: 'box delivery') 
end 



def seller(gig, email, name) 
    @gig = gig 
    @email = email 
    @name = name 
    mail(to: @email, subject: 'new box order') 
end 

Answer 2

如果要通過電子郵件發送有關訂單爲什麼不爲點的順序（購買）買家？然後你就可以使用

@gig = @purchase.gig 
@buyer = @purchase.buyer 

，然後@ buyer.name
