3 深度嵌套形式
我想知道在控制器上处理 3 层深度和更深的嵌套表单的最佳方法是什么
示例：
商店控制器
def new
@user = current_user
@shop = @user.build_shop
@type = @shop.build_type
end
def create
@user = current_user
@shop = @user.build_shop(params[:shop])
@type = shop.build_type(params[:type])
if @shop.save
flash.now[:success] = "blah"
render :show
else
render :new
end
end
I wonder what is the best way to deal with 3 levels deep and deeper of nested forms on controller
An Example:
Shop Controller
def new
@user = current_user
@shop = @user.build_shop
@type = @shop.build_type
end
def create
@user = current_user
@shop = @user.build_shop(params[:shop])
@type = shop.build_type(params[:type])
if @shop.save
flash.now[:success] = "blah"
render :show
else
render :new
end
end

如果 Accepts_nested_attributes_for 变得难以使用，那么您的构建方法实际上是您唯一的其他选择，而无需对代码进行更深入的重构。
If accepts_nested_attributes_for is getting unwieldy, your build methods are really your only other option without doing a deeper refactor of your code.
我建议您阅读 ActiveRecord 的
accepts_nested_attributes_for方法。在大多数情况下，它将消除对所有build_...(...)方法的需要，并且可以与嵌套表单完美配合。I recommend you read up on ActiveRecord's
accepts_nested_attributes_formethod. It will eliminate the need for all of yourbuild_...(...)methods in most all cases, and works beautifully with nested forms.
