在活动管理员中显示错误消息有多个关系表

Question

我正面临一个问题,显示活动管理员中的错误消息.

我收到与表单中的字段一起显示的所有错误消息.但是在下面的代码中,我需要添加至少一项技能和最多5项技能.否则需要抛出错误消息.

我在模型中添加了一个验证:

验证:技能,:length => {:minimum => 1,:maximum => 5,:message =>"应至少为1且小于5"}

这完全验证,但不显示任何错误消息.

任何人都可以帮我显示错误消息.

以下是代码:

form :html => { :enctype => "multipart/form-data" } do |f|

    f.inputs "User", :multipart => true do

        f.input :name
        f.input :email,  :as => :email
        f.input :profile_name
        f.input :date_of_birth
        f.input :gender,  :as => :select, :collection => Gender::GENDERS
      end
      f.inputs "Skills* ( minimum 1 & maximum 5 )" do
        f.has_many :skills do |p|
          if !p.object.nil?
            # show the destroy checkbox only if it is an existing appointment
            # else, there's already dynamic JS to add / remove new appointments
            p.input :_destroy, :as => :boolean, :label => "Destroy?",
                    :hint => "Check this checkbox, if you want to delete this field."
          end
          p.input :description
          p.input :title
        end
      end
    end
  end

activeadmin 0.5.1在github上可用.它包含changelog中的下一行

"添加对@robdiciuccio的语义错误#905的支持"

这是带有此功能的pull请求 https://github.com/gregbell/active_admin/pull/905

例

form do |f|
  f.semantic_errors *f.object.errors.keys
  f.inputs
  f.inputs "Locations" do
    f.has_many :locations do |loc|
      loc.input :address
      loc.input :_destroy, :as => :boolean, :label => "Delete"
    end
  end
  f.buttons
end

使用它添加到Gemfile

gem 'activeadmin', :git =>  "git://github.com/gregbell/active_admin.git", :tag => "v0.5.1"
