无法使用mongrel_rails启动获取值params [：user]第一个请求？

I get nil from params[:user] in create action of my controller for the first request when I start my mongrel server by using mongrel_rails start. After that for second and third time are ok. In addition, if I start my Mongrel by using script/server, it doesn't have any problems at all. It is different by starting mongrel server between script/server and mongrel_rails start? Have you ever faced this problem?

当我使用mongrel_rails start启动我的mongrel服务器时,我在第一个请求的创建操作中从params [:user]获得nil。之后第二次和第三次都可以。另外,如果我使用脚本/服务器启动我的Mongrel,它根本没有任何问题。通过在脚本/服务器和mongrel_rails启动之间启动mongrel服务器是不同的?你有没遇到过这个问题?

Here my code in controller:

这是我在控制器中的代码:

def create
  @user = User.new(params[:user])

  respond_to do |format|
    if @user.save
      flash[:notice] = 'User was successfully created.'
      format.html { redirect_to(@user) }
      format.xml  { render :xml => @user, :status => :created, :location => @user }
    else
      format.html { render :action => "new" }
      format.xml  { render :xml => @user.errors, :status => :unprocessable_entity }
    end
  end
end

And I use Poster add-on to test and post in xml format.

我使用Poster附加组件以xml格式进行测试和发布。

First thing you want to check is the new action in your controller. Second is the erb file which has your form. I have a feeling the text field tags are not proper.

您要检查的第一件事是控制器中的新操作。第二个是具有您的表单的erb文件。我感觉文本字段标签不合适。

I'd recommend inspecting the params object by:

我建议通过以下方式检查params对象:

logger.debug params.inspect # Will show up log/development.log
puts params.inspect # Will show up in server console
