我正在尝试使用 smtp 方法发送邮件，我在 development.rb 文件中完成了其配置，这里是
Rails.application.configure do
config.action_mailer.raise_delivery_errors = true
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
address: 'smtp.gmail.com',
port: 587,
domain: 'example.com',
user_name: 'angad1@gmail.com',
password: xxxxxxxx,
authentication: 'plain',
enable_starttls_auto: true
}
这是邮件文件夹下存在的UserMailer，在这里我从控制器获取参数值，并将参数分配给变量，以便它可以用于视图 UserMailer.rb
class UserMailer < ApplicationMailer
default from: 'angad1@gmail.com'
layout 'mailer'
def conference_result(email,proposal,acknowledgement,positive,negative,chart)
@email = email
@proposal = proposal
@acknowledgement = acknowledgement
@positive = positive
@negative = negative
@chart = chart
mail(to: @email , subject: 'Result for Your conference meeting' , content_type: "text/html")
end
end
这是我想通过邮件传递的内容， mailer.html.erb
<body>
<%= yield %>
<h3 class="text-center" id="proposalhead">Proposal</h3>
<div style="border:1px solid rgba(0,0,0,0.3);background-color: rgba(255,255,255,0.1);margin-top:10px;margin-bottom:10px;" class="text-center">
<%= @proposal %>
</div>
<h3 class="text-center hidden" id ="acknowledgementhead">Acknowledgement</h3>
<div style="border:1px solid rgba(0,0,0,0.3);background-color: rgba(255,255,255,0.1);margin-top:20px;margin-bottom:20px;" id ="Acknowledgement" class="text-center">
<%= @acknowledgement %>
</div>
<h3 class="text-center hidden" id ="positivehead">Positive</h3>
<div style="border:1px solid rgba(0,0,0,0.3);background-color: rgba(255,255,255,0.1);margin-top:10px;margin-bottom:10px;" id ="Positive" class="text-center">
<%= @positive %>
</div>
<h3 class="text-center hidden" id ="negativehead">Negative</h3>
<div style="border:1px solid rgba(0,0,0,0.3);background-color: rgba(255,255,255,0.1);margin-top:10px;margin-bottom:20px" id = "Negative" class="text-center">
<%= @negative %>
</div>
<div id="chart_div" style="width:100%;margin-bottom: 15px;margin-top:15px;" class="text-center">
<%= @chart %>
</div>
</body>
当我尝试发送邮件时，它显示以下错误
ActionView：：MissingTemplate (Missing template user_mailer/conference_result with "mailer"。搜索位置：* "user_mailer"(
请帮帮我，我是红宝石的新手。
正如错误所说，缺少模板user_mailer/conference_result。
您需要创建一个模板app/views/user_mailer/conference_result.html.erb
您似乎缺少邮件模板本身。如果你没有得到它，这就解释了错误 - 否则我会确保它在正确的文件夹中，可能是app/views/user_mailer/conference_result.html.erb和.text.erb.
