我有两个型号更新HAS_ONE关系模型
class User < ActiveRecord::Base
has_one :user_information, :dependent => :destroy
attr_accessible :email, :name
end
和
class UserInformation < ActiveRecord::Base
belongs_to :user
attr_accessible :address, :business, :phone, :user_id
end
创建的用户后,我创建使用新的和我的控制器的创建操作的用户信息:
def new
@user = User.find(params[:id])
@user_information = @user.build_user_information
respond_to do |format|
format.html # new.html.erb
format.json { render json: @user_information }
end
end
def create
@user_information = UserInformation.new(params[:user_information])
respond_to do |format|
if @user_information.save
format.html { redirect_to @user_information, notice: 'User information was successfully created.' }
format.json { render json: @user_information, status: :created, location: @user_information }
else
format.html { render action: "new" }
format.json { render json: @user_information.errors, status: :unprocessable_entity }
end
end
end
一切工作正常,但当我尝试更新记录我得到这个错误:
RuntimeError in User_informations#edit
Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id
下面是编辑和
def edit
@user_information = UserInformation.find(params[:id])
end
def update
@user_information = UserInformation.find(params[:id])
respond_to do |format|
if @user_information.update_attributes(params[:user_information])
format.html { redirect_to @user_information, notice: 'User information was successfully updated.' }
format.json { head :no_content }
else
format.html { render action: "edit" }
format.json { render json: @user_information.errors, status: :unprocessable_entity }
end
end
end
我想我只需要找到记录和编辑,但没有我的user_information控制器的更新操作。任何人都可以帮助我吗?
拼写User_informations#edit'是让我信服。你能显示控制器类名和文件名吗? – ck3g
确定控制器名称是UserInformationsController,文件名是user_informations_controller和编辑记录的路径是http://本地主机:3000 /用户/ 1/user_informations/1 /编辑 – Jean
所以,你的链接帮助应该是'users_user_information(USER_ID, user_info_id)'。助手的名字可以不同,但要注意两个参数。 – ck3g
