There is a way inbetween this too. The Middle Road. And that is how Active
Let us forget about OO vs non OO for a second and look at this:
Comment.title = "Foo Bar"
But you can also do:
:conditions => "id = 12")
..same as above ..
Comment.find_by_sql("select * from comments where id = 12")
..same as above..
Now. The point is that in your Day to Day work, you need not bother about SQL.
But that is not the same as "not being allowed to use SQL".
David Heinemeier Hansson:
"Some object-relational mappers seek to eradicate the use of SQL entirely..."
"..Active record does not. It was built on the notion that SQL is neither
dirty nor bad, just verbose in the trivial cases."
"... Therefore, you shouldn't feel guilgy when you use find_by_sql() to handle
either performance bottlenecks or hard queries. Start out using the
object-oriented interface for productivity and pleasure, and then dip beneath
the surface for a close-to-the-metal experience when you need to".
Which IMO is how we should treat Drupals "abstraction layer" too.
Not try to pull out the SQL etc for sake of abstraction. Not making stuff more
OO for the sake of portability. But only to make working on Drupal more fun,
faster, and more productive.
We should really try to avoid becoming a platform that you "fight against to
get stuff done your way". It should be a fun and productive thing to do,
working on a Drupal site. Working with Drupal should leave you all warm and
fuzzy. With a "wow! this is very smart and usefull" erlebnis every hour.
Instead of a "why the *** cant I just use foo bar here. Wy the *** do i need
to read sqlApiLayers introductions and manuals when all I need is to store a
I am not saying this is the case now. But I fear that if we continue rolling
down the road of more complexity and more abstraction, without remaining
pragmatic, we are going to loose precious developers.
