Trying to replace some .find calls with better code

Hi all,

This forum has been very helpful in the past so I figured I'd try and ask for some help on some (yet again) rather "newbie" stuff again.

I currently have the following DB Schema (Two Tables Listed here):

Users Table (user has_many children)

How about looking into named_scope.

in your Child model:

named_scope :lost,                      :conditions => "is_lost = 't'"

You can then do this:

@user = User.find_by_login(params[:id]) @lost_children = @user.children.lost

/franz

Forgot to mention that named_scope is native Rails 2.1 or later.

If you're using an earlier version, you'll need to install the has_finder plugin.

Try:

  @lost_children = @user.children.select {|c| c.is_lost}
