多级嵌套表单无法批量分配受保护的属性：

Question

我在使用Rails时遇到了很大的问题。问题是，我有32个模型与一个主模型相关联。

模型名为Problem - 每个问题都有leveloneeffect，levelonecause，leveloneend，leveloneway。

现在，每个上一个级别都有与leveltwoeffect相关联的其他模型与leveloneeffect相关联等等。

每个模型都与其他模型正确关联，表单显示正确提交的所有标签和texfield;但是当我提交时，我收到以下错误：

无法批量分配受保护的属性：levelonecause_id

app / controllers / problems_controller.rb：27：在`update'

现在在控制器中，我在27行中有以下代码

def update
    @problem = Problem.find(params[:id])
    @problem.update_attributes(params[:problem])   <--- LINE 27
flash[:notice] = "Programa editado correctamente."
redirect_to edit_problem_path(@problem)     
end

有什么想法吗？

这是我的问题控制器

    def index
        @problem = Problem.all
    end
    def new
        @problem = Problem.new
    end
    def create
        @problem = Problem.new(params[:problem])
        @problem.user_id = current_user.id
        @problem.save
        flash[:notice] = "Prorgrama Creado."
        redirect_to edit_problem_path(@problem)
    end
    def show
    @problem = Problem.find(params[:id])
    end

    def edit
        @problem = Problem.find(params[:id])
    end

    def update
        @problem = Problem.find(params[:id])
        @problem.update_attributes(params[:problem])
        flash[:notice] = "Programa editado correctamente."
        redirect_to edit_problem_path(@problem)


    end

    def destroy
        @problem = Problem.find(params[:id])
        @Problem.destroy
        flash[:notice] = "Programa borrado correctamente."
        redirect_to problems_path
    end
end

这里添加问题模型

 attr_accessible :leveltwocause_attributes,:indicator_attributes, :leveloneeffect_attributes, :levelonecause_attributes, :budget_program, :city, :department, :email, :name, :responsable_unit, :init_date, :end_date, :organism, :definition, :idea_attributes

修改

好的伙计们，我在我的模型中移除了槽，它的工作原理！有谁知道为什么？ 这个新的Rails版本正在杀了我

Answer 1

尝试将:levelonecause_id添加到attr_accessible levelonecause模型列表以及包含它的其他模型中。
