ActiveRecord: Behavior not doumented
Hello everbody, doing a
#find(:first,an_id)
with Rails 1.1.0 I expected that find returns the record which id mathches the
given parameter an_id or nil if it couldn''t be found.
This behaviour is documented on api.rubyonrails.org.
But the find returns the first available object and not nil if an_id is not in
the db. Is the doc on rubyonrails.org out of sync?
Greetings,

problem with has_many associations
...have some problems with a few temporary objects, this is the relation
between them:
A -(1,n)-> B -(1,1)-> C
B -(1,n)-> D
C -(1,n)-> D
I have a "wizard" to create "A" objects, I''m storing everything in the
session, something like this:
a = A.new
session[:a_object] = a
...
b = B.new
b.c = some_c_instace
a.bs << b
...
d = D.new
b.ds << d
then, after the wizard finishes, I want to save the structure in the DB,
like this:
a.save
But it won''t work, active record says that the collections (bs and ds)
are not valid.
I have done this befor...
