问题 How do I edit or override the footer of Active_Admin? 回答1: Answer: In your rails app, create this file: app/admin/footer.rb The content would be something like: module ActiveAdmin module Views class Footer < Component def build super :id => "footer" super :style => "text-align: right;" div do small "Cool footer #{Date.today.year}" end end end end end Don't forget! restart the app/server. Any ActiveAdmin layout component can be customized like this. More about it: Why does it work? This is

问题 In my ActiveAdmin model I have a custom scope to show deleted records and several filters for searching records by specific columns. Using the filters individually or combined together works as expected. Using a scope works as expected. The problem is that using a scope seemingly overrides all the filters and after selecting a scope any filter added does nothing. Anyone have any ideas here? What I want is to be able to show a specific scope and then still be able to filter results within that

问题 Active Admin doesn't seem to support multiple columns sorting yet (i.e. pass multiple values to the config.sortable option). I saw an old monkey patch here but it doesn't seem to work with my version (1.0.0.pre from Github). Is there any way to get multiple sortable columns on the latest Active Admin version? 回答1: This is also a monkey patch: Create a new file in config/initializers or in the lib folder: multiple_columns_sorting.rb module ActiveAdmin class ResourceController < BaseController

问题 Hi guys I'm pretty stuck with building a customised form in active admin. I've figured out and even set up my own customised forms using active admin. However I need to create a dynamic form here. This involves making some ajax calls and returning partials of a form for the user to fill out. It seems that you can create a member action but that is on resources that have been created. In my case I need to create multiple entries on a resource that is yet to be created. 回答1: This might get you
