Activeadmin: 如何传递验证错误并保留值

创建于 2016-12-08 · 3评论 · 资料来源: activeadmin/activeadmin

你好，我有一个自定义控制器（我将它用作问题 #4685 的补丁）
我需要解决的问题是验证错误和保留表单数据。在我做自定义控制器之前，错误会像这样在输入字段下方弹出

但现在他们没有出现。请帮忙！谢谢：）

ActiveAdmin.register

controller do
        def create
          <strong i="12">@section</strong> = AbqCouncilors::Councilor.create!(permitted_params[:abq_councilors_councilor].as_json)
              redirect_to admin_faq_sections_path, notice: "Section was successfully created!"          
        end
    end

我通过以下更改得到了它。
重要必须有@resource作为实例变量。不会与任何其他人一起工作

controller do
        def create
          <strong i="9">@resource</strong> = AbqCouncilors::Councilor.new(permitted_params[:abq_councilors_councilor].as_json)
            if @resource.save
                flash[:notice] = "Councilor was successfully created!"
                redirect_to admin_abq_councilor_path(@resource.id)
        else
            flash[:error] = "Your form is missing or has incomplete fields. Please review your entry below."
                render action: 'new'
         end
        end
    end

看起来它应该在验证器错误时引发错误或继续在列表上重定向。您必须在create操作方法中编写额外的逻辑。

@dmitry有例子吗？
