问题 I am developing an app using Devise, Rolify and CanCan. Can I shift it completely to be administered by ActiveAdmin.

问题 I need help!

问题 I've got a model in which a very small percentage of the objects will have a rather large descriptive text. Trying to keep my database somewhat normalized, I wanted to extract this descriptive text to a separate model, but I'm having trouble creating a sensible workflow in ActiveAdmin. My models look like this: class Person < ActiveRecord::Base has_one :long_description accepts_nested_attributes_for :long_description, reject_if: proc { |attrs| attrs['text'].blank? } end class LongDescription

问题 I have a namespace admin . I would like to apply a before_filter only to this namespace (not the default one, which is superuser ). I can add the following code in active_admin.rb ns.before_filter :is_subscribed? But then, the superuser gets the filter too. I tried adding the before_filter inside my namespace configuration : config.namespace :admin do |ns| ... ns.before_filter :is_subscribed? end but Rails throws an error : undefined method `before_filter' for #<ActiveAdmin::Namespace

问题 I would like the admin_user to be able to reset user´s password from Active Admin edit_page, but am currently stuck. My idea was to make an action_item button and launch @user.send_reset_password_instructions method from devise authentication gem for a users object which works. But, action_item cannot get any notice: message and that´s where I´m stuck. Can you please help me implement the action_item button which could launch the @user.send_reset_password_instructions, redirect to the same

问题 I inherited a project that is using ActiveAdmin with Formtastic in Rails. I have very little experience with either of these, but it seems simple enough to do simple tasks. So, I have been tasked with adding a radio input, but hides the another input if the radio doesn't match a certain value. I've search everywhere and can't seem to find anything on this.

问题 I'm having trouble implementing a form on active admin where the second dropdown (subcategory) has to adjust to the category choice on the drop down that precedes it. Basically I want to first set a industry for a company then select among sub-industry drop down.
