**Request
Parameters:**
{"utf8"=>"✓",
"_method"=>"patch",
"authenticity_token"=>"rXhIA6/LAP8Kla9kMExq16bpr51WeFyPo0vDi9sE86c=",
"id"=>"2",
"user"=>{"role_id"=>"3"},
"commit"=>"Change Role"}
如何從控制器中的「role_id」獲取參數3? 我試圖如何在rails中處理參數?
@role = (params[:user])
,但我只得到
{"role_id"=>"2"}
嘗試'@Role =(PARAMS [:用戶] [:ROLE_ID])' – anusha 2014-10-29 09:35:19
