我正在尝试将邮件程序集成到我的应用程序中。下新订单时，我需要发送一封交易电子邮件。将收件人传递给邮件程序时，我一直遇到无方法错误。当我明确定义收件人时，这很好用，但我需要将收件人变量从我的模型传递给消息，以获得我想要的行为。任何帮助调试将不胜感激，因为我似乎无法追查我的错误。
错误输出：
NoMethodError (undefined method `recipient' for nil:NilClass):
app/mailers/bed_mailer.rb:8:in `bed_email
邮件：
class BedMailer < ApplicationMailer
default :from => 'info@paperlesspcs.com'
def bed_email(bed)
@bed = bed
mail(
:subject => 'Critical Documentation Needed' ,
:to => @bed.recipient ,
:track_opens => 'true',
:body => 'something'
)
end
end
关联控制器操作：
def create
@bed = current_supplier.beds.build(bed_params)
respond_to do |format|
if @bed.save
BedMailer.bed_email(@beds).deliver_later
format.html { redirect_to @bed, notice: 'Bed was successfully created.' }
format.json { render :show, status: :created, location: @bed }
else
format.html { render :new }
format.json { render json: @bed.errors, status: :unprocessable_entity }
end
end
编辑/更新
我更正了下面评论中提到的拼写错误，但是当我删除该:body行以转发到我的首选邮件布局时，现在遇到了无模板错误Missing template bed_mailer/bed_email with "mailer". Searched in: * "bed_mailer"
我的预期布局：
bed_mailer.html.erb
<h2> Critical Documentation Needed: </h2>
<p> In order to quickly process your referral for <strong> <%= @bed.patient_name %> </strong>, we need additional documentation.
