Rails 4.1 introduced enumerations that break rails_admin . Any solutions or work around?
My model includes the following line at the top
enum category: {industry: 1, company: 2, event: 3}
My gemfile has the following line
gem 'rails_admin', :git => 'git://github.com/sferik/rails_admin.git'
There is no other code related to this problem. I have not changed the default rails_admin behavior. Below are the errors that occur when trying to change any model that contains the enum attribute through the rails_admin interface.
ArgumentError - '3' is not a valid category:

What happens is that rails_admin does not recognize enumerations, but in its interface it displays them as numbers instead of strings. Then, when you click the "Save" button, it throws an exception above.
