嗨，我知道Rails 4正在使用强参数，我需要在控制器中允许它们，这是我的工作，但我仍然会收到此错误。
我的请求看起来像是
{"utf8"=>"✓",
"authenticity_token"=>"cAJLJGiywr4TeAEpidQ1/XstiSNO+819W4QBhgMGNczVret+H/XDDVk3l1UpoaK8tHVK6qf+KK8VjBdM51zocA==",
"estate"=>{"building_id"=>"1",
"planet_id"=>"1",
"number"=>"2"},
"commit"=>"Build",
"locale"=>"en"}
在我的控制器中我试过
def estate_params
params.require(:estate).permit(:building_id, :planet_id, :number)
end
@estate = Estate.new(estate_params)
或
Estate.new(params[:estate].permit(:building_id, :planet_id, :number))
任何人都可以向我解释为什么我会收到此错误？
由于
