Ruby on rails RubyonRails发送电子邮件时遇到问题

首先：这是我的第一个问题，所以请让我知道，如果我不在这里做的话，我以后如何能更好地提问。我对ROR也比较陌生

问题:

我正在尝试让我的web应用程序在我的开发环境中发送电子邮件。它不起作用了。我不完全清楚为什么。版本：Rails 4，Ruby 2

当前浏览器问题：

ActionController::ParameterMissing in ProfilesController#update
param is missing or the value is empty: profile

Extracted source (around line #83):81 82 83 84 85

# Never trust parameters from the scary internet, only allow the white list through.
def profile_params
    params.require(:profile).permit(:user_id, :first_name, :last_name, :dob, :email, :mobile, :address, :suburb, :postcode, :city, :state, :country)
end

Application Trace | Framework Trace | Full Trace
app/controllers/profiles_controller.rb:83:in `profile_params'

Request

Parameters:

{"utf8"=>"✓",
 "_method"=>"put",
 "authenticity_token"=>"Px14k13lkQa6d8V61K6dvwLN5xhqjieE8Yk5LjiW1z8=",
 "destination"=>"test@gmail.com",
 "commit"=>"Send Email",
 "id"=>"1"}

路线：

resources :profiles do
    put :email
end

配置文件控制器：

def email
    destination = params[:to]
    share = Share.profile(@profile, destination)
    if destination =~ /@/ && share.deliver
        redirect_to @profile, notice: 'email sent :)'
    else 
        redirect_to @profile, notice: 'email failed :('
    end
end

# Never trust parameters from the scary internet, only allow the white list through.
def profile_params
    params.require(:profile).permit(:user_id, :first_name, :last_name, :dob, :email, :mobile, :address, :suburb, :postcode, :city, :state, :country)
end

共享邮件发送人：

class Share < ActionMailer::Base
    default_url_options[:host] = "localhost:3000"
    default from: "from@example.com"

    def profile(profile, destination)
        @user = profile.user
        @profile = profile
        mail to: destination, 
             subject: "#{@user.email} sent you stuff")
    end
end

查看/配置文件/显示：

    <!-- Button trigger modal -->
<button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
  Email
</button>

<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-    labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">&times;</span><span class="sr-only">Close</span></button>
        <h4 class="modal-title" id="myModalLabel">Share my Info with someone</h4>
      </div>
      <div class="modal-body">
        <%= form_tag profile_path(@profile), method: :put do %>
          <%= label_tag :destination, "What email address would you like to send this to?" %>
          <%= text_field_tag :destination %>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
        <%= submit_tag "Send Email", class: "btn btn-primary" %>
        <% end %>
      </div>
    </div>
  </div>
</div>

非常感谢您的帮助！我不知道哪里出了问题！干杯

您在提交表单时正在调用更新操作。请尝试更改此行，然后重试：

        <%= form_tag profile_path(@profile), method: :put do %>
to
        <%= form_tag email_path(@profile), method: :put do %>

控制器：

def email
    destination = params[:to]
    share = Share.profile(@profile, destination)
    if destination =~ /@/ && share.deliver
        redirect_to @profile, notice: 'email sent :)'
    else 
        redirect_to @profile, notice: 'email failed :('
    end
end

# Never trust parameters from the scary internet, only allow the white list through.
def profile_params
    params.require(:profile).permit(:user_id, :first_name, :last_name, :dob, :email, :mobile, :address, :suburb, :postcode, :city, :state, :country)
end

您的代码正在调用更新操作，而不是电子邮件操作。更改您的表单以提交电子邮件操作。感谢您回复@sevensacat和@anusha！我将行更改为email_path，但现在我得到：NoMethodError in profiles show undefined method`email_path'，我不确定为什么它没有定义，因为它已经在控制器中定义了？我还尝试了“电子邮件”配置文件_path@profile但也有同样的问题，我在用Desive。我不确定这是否会造成干扰？@sss333您是否在路由中包含了它的root。rb类似于：match'/email'=>“profileemail”…仍然返回一个错误：match'/email'=>“profileemail”返回：RuntimeError您不应该在没有指定HTTP方法的情况下在路由器中使用match方法。如果您想向GET和POST公开您的操作，请通过：[：GET，：POST]选项添加。如果你想暴露你的行为以获得，在路由器中使用get：而不是：match controlleraction Do:get controlleractionget'/email'=>“profileemail”返回：ActionController:：ParameterMissing in profiles controllerUpdate param丢失或值为空：第83行周围提取的配置文件源：def profile\u params参数。需要：配置文件。允许：用户\u id，：名字：：姓氏：：dob，：email，：mobile，：address，：country，：postcode，：city，：state，：country end profiles\u controller.rb:83:in profile\u params'app/controllers/profiles\u controller.rb:45:in block in update'app/controllers/profiles\u controller.rb:44:in'update'

get 'email_profile' => 'profiles#email_profile'

def email_profile
    @profile = params[:profile]
    destination = params[:to]
    share = Share.profile(@profile, destination)
    if destination =~ /@/ && share.deliver
        redirect_to @profile, notice: 'email sent :)'
    else 
        redirect_to @profile, notice: 'email failed :('
    end
end
