Tag: conditions

I’m sure you all know how to use the :conditions attribute when using ActiveRecord:

User.find(:all, :conditions=>['active = ?', true])

And you may even use associations this way:

User.find(
  :all,
  :include=>[:photos],
  :conditions=>['photos.removed = ? and users.active = ?', false, true]
)

But did you know that you can do this easier through hashes?

User.find(:all, :conditions=>{:active=>true})
User.find(
  :all,
  :include=>[:photos],
  :conditions=>{'photos.removed'=>false, 'users.active'=>true}
)

Nothing special there, but I thought it was pretty cool. One thing you have to remember when using associations, is to include that model.
