我需要一个按钮，当我点击它时，必须在用户表中更新name属性，并且地址必须保存在地址表中。地址表属于用户表。现在我的错误是，当我点击提交按钮时，我无法保存地址，但我的名字在用户表中更新。任何人都可以帮忙吗？
控制器代码
class ProfileController < ApplicationController
before_action :set_user, only: %i[index update_profile]
def index; end
def create
@address = Address.new(address_params)
respond_to do |format|
puts'-=-==-=-=-=-=-=-=-=-=-=-=-=-==-=-=-=-='
if @address.save
format.html { redirect_to profile_index_path, notice: 'Address was successfully created.' }
else
format.html { render :new }
end
end
end
def update_profile
respond_to do |format|
if @user.update(user_params)
format.html { redirect_to profile_index_path, notice: 'Profile was successfully updated.' }
else
format.html { render :index }
end
end
end
private
def set_user
@user = User.find(current_user.id)
@user.address || @user.build_address
end
def user_params
params.require(:user).permit(:name, address_attributes: %i[area state country])
end
def address_params
params.require(:address).permit(address: %i[area state country])
end
end

我省略了一些与错误无关的方法，并对控制器进行了一些更改：
class ProfileController < ApplicationController
def create
@address = Address.new(address_params)
respond_to do |format|
if @address.save
format.html { redirect_to profile_index_path, notice: 'Address was successfully created.' }
else
format.html { render :new }
end
end
end
def update_profile
respond_to do |format|
if @user.update(user_params)
format.html { redirect_to profile_index_path, notice: 'Profile was successfully updated.' }
else
format.html { render :index }
end
end
end
private
def user_params
# changed `address_attributes` to `address` as the params in request contains key `address`
params.require(:user).permit(:name, address: %i[area state country])
end
def address_params
# permit the attributes directly instead of nesting them under another `address` key
params.require(:address).permit(*%i[area state country])
end
end
如果它不起作用，请告诉我。

请在您的用户模型中添加以下行
user.rb
accepts_nested_attributes_for :address
