我正在处理活动的admin gem.我只想隐藏显示页面中的删除链接.所以,我添加了以下代码

ActiveAdmin.register ArticlesSkill do
  menu :parent => "ReadUp"
  actions :index, :show, :new, :create, :update, :edit

  index do
    column :name, sortable: :name
    column :description 
    column "" do |resource|
      links = ''.html_safe
      links += link_to I18n.t('active_admin.view'), resource_path(resource), :class => "member_link edit_link"
      links += link_to I18n.t('active_admin.edit'), edit_resource_path(resource), :class => "member_link edit_link"
      if Article.where(articles_skill_id: resource.id).blank?
        links += link_to I18n.t('active_admin.delete'), resource_path(resource), :method => :delete, :confirm => I18n.t('active_admin.delete_confirmation'), :class => "member_link delete_link"
      else
        # links += link_to I18n.t('active_admin.delete'), "#", :confirm => ("This Skill …

 def confirm_invite_new_tutor
    redirect_with_msg = false
    @game_school = GameSchool.find(params[:id])
    existing_user_emails = params[:all_emails][:existing_user] || []
    new_users = params[:param_game_school][:game_school_invites_attributes]

if existing_user_emails.present?
      existing_user_emails.each do |existing_user|
        // some code
      end
      redirect_with_msg = true
    end
    if new_users.present? 
      if @game_school.update_attributes(params[:param_game_school])
        redirect_with_msg = true
      else
         render :invite_tutor_form
      end
    end
    if redirect_with_msg 
      redirect_to @game_school, notice: "daw"
     else
      redirect_to @game_school 
    end
  end

如果我正在执行此操作,我会收到错误

在此操作中多次调用渲染和/或重定向.请注意,您只能调用渲染或重定向,每次操作最多一次.另请注意,重定向和呈现都不会终止操作的执行,因此如果要在重定向后退出操作,则需要执行类似"redirect_to(...)并返回"的操作.

如果我使用return它将我带到其他页面,甚至不显示flash msg.如何解决这个问题？

我正在尝试创建一篇文章.

class Article < ActiveRecord::Base

 belongs_to :article_skill
  attr_accessible :articles_skill_attributes

  accepts_nested_attributes_for :articles_skill 
end

class ArticlesSkill < ActiveRecord::Base
  attr_accessible :description, :name

  has_many :articles

end

这是我的形式 article/new.html.erb

 <%= article_form.fields_for :articles_skill, @article.articles_skill do |b|%>
    <label class="medium"><span class="red">*</span> Skill</label>
    <%= b.select :id, options_for_select(ArticlesSkill.all.collect{|m| [m.name, m.id]}) %>  
  <%end%>

这article_form是@article表单对象的构建器.

如果我尝试保存@article对象,则显示此错误.

Couldn't find ArticlesSkill with ID=1 for Article with ID=
