Ruby on Rails _使用Active Admin后台模板 三 新增一个 post

跟着上文继续走。 Post已经有了，新建Post 的时候结果报错了：

链接：​​https://github.com/activeadmin/activeadmin/blob/master/docs/2-resource-customization.md#setting-up-strong-parameters​​

#app\admin\posts.rb
ActiveAdmin.register Post do
  permit_params :title, :content, :publisher_id

  # See permitted parameters documentation:
  # https://github.com/activeadmin/activeadmin/blob/master/docs/2-resource-customization.md#setting-up-strong-parameters
  #
  # Uncomment all parameters which should be permitted for assignment
  #
  # permit_params :title, :content
  #
  # or
  #
  # permit_params do
  #   permitted = [:title, :content]
  #   permitted << :other if params[:action] == 'create' && current_user.admin?
  #   permitted
  # end
  
end

然后继续新建：

盗文章的比较多，我尽量截图来搞了。

另外菜单会自动加进去

#app\admin\posts.rb
ActiveAdmin.register Post do
  menu false
  permit_params :title, :content, :publisher_id

  # See permitted parameters documentation:
  # https://github.com/activeadmin/activeadmin/blob/master/docs/2-resource-customization.md#setting-up-strong-parameters
  #
  # Uncomment all parameters which should be permitted for assignment
  #
  # permit_params :title, :content
  #
  # or
  #
  # permit_params do
  #   permitted = [:title, :content]
  #   permitted << :other if params[:action] == 'create' && current_user.admin?
  #   permitted
  # end
  
end

这样的话会隐藏菜单

也可以自定义标题

ActiveAdmin.register Post do
  menu label: "自己搞的标题",priority: 1
#priority是标题位置，默认是10
  permit_params :title, :content, :publisher_id

  # See permitted parameters documentation:
  # https://github.com/activeadmin/activeadmin/blob/master/docs/2-resource-customization.md#setting-up-strong-parameters
  #
  # Uncomment all parameters which should be permitted for assignment
  #
  # permit_params :title, :content
  #
  # or
  #
  # permit_params do
  #   permitted = [:title, :content]
  #   permitted << :other if params[:action] == 'create' && current_user.admin?
  #   permitted
  # end
  
end
