Advanced ActiveRecord tutorials

Any recommendations for good advanced tutorials on ActiveRecord in
Rails4?

I’m interested in joins, group, counts especially for deep associations.

Thanks,
Ganesh

Hi Ganesh,

The official Ruby on Rails guides has a pretty extensive coverage of
ActiveRecord Active Record Query Interface — Ruby on Rails Guides
If you want to achieve something specific, then you’ll find a lot of
tutorials for that. And as always you can ask here as well :slight_smile:

Hope this helps.

It’s not really a tutorial, but if you really want an advance discussion
and in-depth coverage of ActiveRecord, I would recommend The Rails 4
Way which,
in my opinion, is the best reference for back end development on Rails.
I
don’t have any connection to the book or its authors, but I use it a
lot.

Here’s a list of articles on advanced ActiveRecord, quite old but I
think
they are still relevant.

Have a nice day and good reading !
