這似乎是一個常見錯誤,我讀過很多回復。我必須失去一些愚蠢的東西。rails:無法批量分配受保護的屬性
我有一個位置的活動。 (HAS_ONE)。我已經設置了accep_nested_attributes_for:location,我相信我有單數/複數的權利(所有單數,這是一個has_one關係)。 (我已經嘗試列出每個屬性的attr_accessible單獨,沒有骰子。)我已經重新啓動我的服務器。然而,我不斷收到:
無法大規模指派保護的屬性:地址,LOCATION_NAME, PHONE_NUMBER,區,郵編,城市,國家,緯度,
class Activity < ActiveRecord::Base
attr_accessible :beer, :user, :whatdoing, :where, :with, :location_id, :location_attributes
has_one :location, :dependent => :destroy
accepts_nested_attributes_for :location
validates :whatdoing, :numericality => { :only_integer => true, :greater_than => -1}
end
class Location < ActiveRecord::Base
validates_presence_of :address
belongs_to :activity
end
活動控制器:
# GET /activities/new.json
def new
@activity = Activity.new
@activity.build_location
respond_to do |format|
format.html # new.html.erb
format.json { render json: @activity }
end
end
# PUT /activities/1
# PUT /activities/1.json
def update
@activity = Activity.find(params[:id])
respond_to do |format|
if @activity.update_attributes(params[:activity])
format.html { redirect_to @activity, notice: 'Activity was successfully updated.' }
format.json { head :no_content }
else
format.html { render action: "edit" }
format.json { render json: @activity.errors, status: :unprocessable_entity }
end
end
end
它必須是簡單的東西,但我無法發現它。
在此先感謝!

你能發佈你的嵌套表單代碼嗎? –
