Question

我在我的控制人员之一(在铁路3.1号申请中)中有以下守则很好地发挥作用:

def index
    #@calls = Call.all
    @calls = Call.where(:destination =>  12345678 ).limit(25)

    respond_to do |format|
      format.html # index.html.erb
      format.json { render :json => @calls }
    end
end

我试图从这里找到最佳操作方法,基本上每个用户都有自己的目的地代码(在这种情况下,是1245678页)。

用户能否在能够传入控制器的模式中具有价值?

实例

def index
    #@calls = Call.all
    @calls = Call.where(:destination =>  <% @user.destination %> ).limit(25)

    respond_to do |format|
      format.html # index.html.erb
      format.json { render :json => @calls }
    end
end

我确信,上述法典将不奏效,但要实现同样的东西,将做些什么?

2. 更新资料,少有新资料:

我有两个模式,一个是电话,另一个是用户。

我想这样做:

@calls = Call.where(:destination => @user.destination_id).limit(25)

如果:目的地是呼吁模式的一部分,目的地是用户模式的一部分。每个用户都有不同的目的地——id值。

您可在<条码>第阵列中将目的地传送给控制员。这样,你们就能够像控制者一样获得控制。

def index     
  #@calls = Call.all
  @calls = Call.where(:destination => current_user.destination_id).limit(25)

  respond_to do |format|       
    format.html # index.html.erb
    format.json { render :json => @calls }     
  end
end
