更改模型属性的值答案

【问题描述】：

我正在使用 Twilio 发送 SMS 消息以更改特定模型（用户）属性的值（在本例中为：money）。

我成功地从 Twilio POST 中提取了参数，尽管没有运气将属性更改保存到模型的属性中。有什么想法吗？

这是我在用户控制器中“更新”的代码：

  def update
    @user = User.find(params[:id])

    respond_to do |format|
      if @user.update_attributes(params[:user])
        format.html { redirect_to @user, notice: 'User was successfully updated.' }
        format.json { head :no_content }

      else
        format.html { render action: "edit" }
        format.json { render json: @user.errors, status: :unprocessable_entity }
      end
    end

    require 'rubygems'
    require 'twilio-ruby'

    @account_sid = 'AC0626c6d8dc0a4551b159161c5ca7ced2'
    @auth_token = '**********************************'

    # set up a client to talk to the Twilio REST API
    @client = Twilio::REST::Client.new(@account_sid, @auth_token)

    message_body = params["Body"]
    from_number = params["From"]

    if from_number == "+**********"
      @user = User.find(1) # :select => :money
      existing_money = @user.money
      doug_sum = message_body.to_f + existing_money

      @user.money = doug_sum
      @user.save

      puts "This is Doug's sum: #{doug_sum} and it has been saved"
    else
      puts "This is not a valid frump number"  
    end

  end

Heroku 服务器的日志如下：

最后，这是接收短信的 Twiml 文件：

<?xml version="1.0" encoding="UTF-8" ?> 
<Response>
    <Redirect method="POST">http://frump.herokuapp.com/users</Redirect>
</Response>

查看代码如下：

<% @users.each do |user| %>
  <tr>
    <td><%= user.name %></td>
    <td>$<%= user.money %></td>
    <td><%= link_to 'Show', user %></td>
    <td><%= link_to 'Edit', edit_user_path(user) %></td>
    <td><%= link_to 'Destroy', user, method: :delete, data: { confirm: 'Are you sure?' } %></td>
  </tr>
<% end %>
</table>

提前致谢！

【问题讨论】：

请发布您的查看代码。正如我在 Heroku 服务器日志中看到的那样，您的参数看起来像 Parameters: {"AccountSid"=>"AC0626c6d8dc0a4551b159161c5ca7ced2", "Body"=>"4", "ToZip"=>"13203", "FromState"=>"NY", "ToCity"=>"SYRACUSE", "SmsSid"=>"SMa973490ac1db98b25247b600fe068d6f", "ToState"=>"NY", "To"=>"+13158491369", "ToCountry"=>"US", "FromCountry"=>"US", "SmsMessageSid"=>"SMa973490ac1db98b25247b600fe068d6f", "ApiVersion"=>"2010-04-01", "FromCity"=>"SYRACUSE", "SmsStatus"=>"received", "From"=>"+13154368655", "FromZip"=>"13135"} 但它应该看起来像 Parameters: {"user" => {"AccountSid" => ..}}
贴出查看代码——感谢您的帮助：
嗨，我建议逐步检查您的逻辑，并在每种情况下检查您的假设。你真的检索用户对象吗？您是否有“发件人”号码？ user.save 是否更新存储在数据库中的值？这些都是代码可能被破坏的地方，最好检查每个地方。

【解决方案1】：

日志显示WARNING: Can't verify CSRF token authenticity，因此可能由于您的rails 应用程序端的身份验证失败，您没有从“twilio”获取数据。喜欢有

protect_from_forgery

在您的应用程序控制器中。

尝试从伪造保护中排除您的行为，然后查看类似

class UsersController < ApplicationController
  protect_from_forgery :except => ["create"]
end
