Rails 3. How to add a helper that ActiveAdmin will use?
You can define them in app/helpers/ as you tried but you need to include them trough the active admin's initializer like this:
# in config/initializers/active_admin.rbActiveAdmin.setup do |config| ....endmodule ActiveAdmin::ViewHelpers include ApplicationHelperend
You need to put your helper functions in app/helpers/active_admin/views_helper.rb file Example:
module ActiveAdmin::ViewsHelper #camelized file name def my_helper # do something end end
What I have found using ActiveAdmin 0.6.1 is that ActiveAdmin will look for helpers in app/helpers/active_admin/*_helper.rb, but the name doesn't really matter.
What does matter is:
- the filename must end in "_helper.rb"
- the module name must be the camel-case of the file name
- the file must be in app/helpers/active_admin/ directory.
If anyone knows where this is officially documented, that would be awesome.
