带有 mailgun 和 rails 的电子邮件未发送给所有用户

Question

每次发布​​博客文章时，我都会尝试向所有用户发送电子邮件。 Mailgun 似乎会发送电子邮件，但总是只发送给一个用户。我正在生产中运行它。

我在邮件中的代码是这样的

 def new_record_notification(users)
      @users = User.all
        @users.each do |user| 
            mail to: user.email, subject: "Success! You did it."
        end
      end
    end

pins_controller.rb

 # POST /pins
  # POST /pins.json
  def create
    @pin = current_admin.pins.new(pin_params)

    respond_to do |format|
      if @pin.save
        ModelMailer.new_record_notification(@record).deliver
        format.html { redirect_to @pin, notice: 'Pin was successfully created.' }
        format.json { render action: 'show', status: :created, location: @pin }
      else
        format.html { render action: 'new' }
        format.json { render json: @pin.errors, status: :unprocessable_entity }
      end
    end
  end

我想这会解决你的问题。

ma​​iler.rb

def new_record_notification(user)
  mail to: user.email, subject: "Success! You did it."
end

pins_controller.rb

def create
    @pin = current_admin.pins.new(pin_params)

    respond_to do |format|
      if @pin.save
        @users = User.all
        @users.each do |user| 
          ModelMailer.new_record_notification(user).deliver
        end
        format.html { redirect_to @pin, notice: 'Pin was successfully created.' }
        format.json { render action: 'show', status: :created, location: @pin }
      else
        format.html { render action: 'new' }
        format.json { render json: @pin.errors, status: :unprocessable_entity }
      end
    end
  end
