I found a way to do this that leverages i_r's :finder
option on the controller. I am using stringex and have a slug
column on the Model. So
ActiveAdmin.register Category do
controller do
defaults :finder => :find_by_slug
end
end
from activeadmin.
You should be able to implement this using the to_param and using a before filter in the resource.
I haven't actually tested this, so let me know if this works... But it should look something like this.
class Post < ActiveRecord::Base
def to_param
uuid
end
end
ActiveAdmin.register Post do
before_filter :only => [:show, :edit, :update] do
@post = Post.find_by_uuid(@post)
end
end
Active Admin should use the @post variable instead of looking it up if you have already defined it.
Again, I haven't had a chance to test this out, but we use this method for show screens in our app. I'm assuming it will work for the edit and update.
Let me know how it goes.

Actually this should read:
before_filter :only => [:show, :edit, :update] do
@post = Post.find_by_uuid!(params[:id])
end
Adding the ! gives you the nice 404 behavior, and @post is not defined at this point, params[:id] is.

@malyk did this work for you?

I actually never tried it. Got caught up on other things. If I do give it another go (which I do want to do when time permits) I'll let you know. Thanks for looking into it.
