过滤器链暂停为[:login_required] rendered_or_redirected

Question

希望我能够很好地解释这一点,但如果需要更多信息,请告诉我!

我正在构建一个用户可以创建"事件"的表单.此事件具有以下关系:

• belongs_to:客户(客户has_many事件)
• belongs_to:user(用户has_many事件)
• has_one:incident_status(incident_status属于事件)

该表单允许用户将事件分配给用户(选择表单),然后选择事件状态.事件嵌套在客户中.

但是,我在服务器日志中获得以下内容:

Processing IncidentsController#create (for 127.0.0.1 at 2010-04-26 10:41:33) [POST]
Parameters: {"commit"=>"Create", "action"=>"create", 
"authenticity_token"=>"YhW++vd/dnLoNV/DSl1DULcaWq/RwP7jvLOVx9jQblA=", 
"customer_id"=>"4", "controller"=>"incidents", "incident"=>{"title"=>"Some Bad Incident", 
"incident_status_id"=>"1", "user_id"=>"2", "other_name"=>"SS01-042310-001"}}

User Load (0.3ms)   SELECT * FROM "users" WHERE ("users"."id" = 2) LIMIT 1
Redirected to http://localhost:3000/session/new
Filter chain halted as [:login_required] rendered_or_redirected.
Completed in 55ms (DB: 0) | 302 Found [http://localhost/customers/4/incidents]

在我看来,它正在尝试收集有关用户的信息,即使它已经有了id(这是创建事件所需的全部内容),并且用户可能没有权限执行这样的select语句？我很困惑.

这是事件控制器中的相关(我认为)信息.

before_filter :login_required, :get_customer

def new
  @incident = @customer.incidents.build
  @users = @customer.users
  @statuses = IncidentStatus.find(:all)

  respond_to do |format|
    format.html # new.html.erb
    format.xml  { render :xml => @incident }
  end
end

def create
  @incident = @customer.incidents.build(params[:incident])

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

就像一个FYI,我正在使用restful_authentication插件.

总而言之,当我提交事件创建表单时,它不会保存事件,因为它会停止.我对rails很新,所以我在诊断这类问题方面的技能仍然非常糟糕.我要去圈子了.:)

在此先感谢您的帮助.如果需要更多信息,请告诉我,我会对其进行编辑!

Answer 1

只需在控制器中使用以下内容

before_filter :login_required, :except=>[:new, :create]

Answer 2

或者您可以跳过此过滤器:

skip_before_filter :login_required, only: [:new, :create]
