What might this be: New Active Record chainable query language built on top of relational algebra?

Question

I saw this on a blog today, and I thought, finally! Rails will have something like HQL or Linq. Um, or not. I couldn't find anything about this.

What I really want to know: will I be able to forget what the tables are called and use the object names only? Can I finally forget join syntax? I'd like to do that before I start forgetting everything else (life goals).

Answer 1

You can read more about it here. I'm not terribly familiar with LINQ, but I believe LINQ is somewhat similar to the query interface used by Django's ORM. At any rate, the gist is that the query interface in Active Record is more like that of Django that it was before. A lot of the older "low-level" query methods are deprecated and will be removed in later versions.

Answer 2

As far as I understand, this means that you can write your complex queries not as

Object.find(:all, :conditions = > { :limit => 10, :offset => 5 }

but more readable way

Object.all.limit(10).offset(5)
