问题 It's probably a dead simple question. Right now it uses the default application layout file. How can I create one just for AdminAdmin in order keep it separate from the one used on the main site? 回答1: Read layouts and rendering guide, there is paragraph about :layout option. You can specify layout, or set it to false, to render without layout at all. render :layout => 'special_layout' render :layout => false 回答2: If my memory does not fail me again !! ;-) this rails cast talk about this. But

问题 I'm using ActiveAdmin. I have a list of Shipments with status (as a string) of Open and Closed. When the user clicks on the Shipments tab, I want to display only the Open shipments. How can I do that? Of course, the user could later choose to see the Closed shipments by using the filter. But I want the default to initially only show the Open shipments. 回答1: Probably best way will be to create scopes in model. AA automatically gets your scopes and creates tabs above table in index view.

问题 In a Ruby on Rails app that heavily relies on ActiveAdmin, I have a Sponsor model, which is associated with a Sponsorship model. One sponsor can sponsor many children, so one sponsor can have many sponsorships . What I would like to do, is to be able, on the Sponsor index page, to filter out sponsors by the number of sponsorships they have. So that, for example, I want to see only those sponsors who have more than one sponsorship, or less than five, and so on. You get the idea. In Ruby-speak,

问题 When an admin logs in, it automatically redirects to the main home page (i.e. not the admin dashboard). I'm not sure why it does this or how to change it... routes.rb ActiveAdmin.routes(self) devise_for :admin_user, ActiveAdmin::Devise.config get "guidelines/topic" get "guidelines/topichospital" get "guidelines/topicspecialty" get "guidelines/favourite" get "profiles/show" get "guidelines/show" root :to => 'guidelines#index' my application_controller.rb has been changed to redirect after user

问题 I have a Post model, PostSource model. A PostSource has many posts, a post belong to one PostSource. Using ActiveAdmin, in the Index action of the Post, I am displaying a filter of PostSource this way: filter :post_source, label: 'Source' filter :category, as: :select, collection: Category.order(:name).collect { |cat| [cat.name, cat.id] } with the controller as: controller do def scoped_collection end_of_association_chain.includes(:post_source) end end It displays the source, but does not

问题 I am using the Active Admin gem and I would like to hide or remove the links on the index page of each model allowing users to download data as CSV, XML or JSON. Is there any way to do this? 回答1: There is now an option :download_links on the index method, so you omit the download links if you want. For example: ActiveAdmin.register Post do index :download_links => false do # whatever end end 回答2: You should use it as a option of index, but do not separate it from the column functions. Use it

问题 This seems like it should be relatively simple, but I've had some trouble tracking down the answer: How do you set the page title in ActiveAdmin? 回答1: Consolidating answers and adding a little: Most of this is on this page on the wiki (or I'll put it there soon). Within the file that registers your model for activeadmin (e.g. app/admin/user.rb), you can have ActiveAdmin.register User do # a simple string index :title => "Here's a list of users" do ... end # using a method called on the
