Updating a belongs_to foreign key leaves the old association object available
Perhaps this is intentional, but it seems unlikely:
class Person < ActiveRecord::Base
belongs_to :school
end
p = Person.find(:first)
p.school # nil
p.school_id = School.find_by_name(''High School'').id
p.school.name # High School
p.school_id = School.find_by_name(''Primary School'').id
p.school.name # High School <= Shouldn''t this be Primary

validates_uniqueness_of does not pass unit test
I am doing some very very basic unit testing. If I take away the
uniqueness validation, the tests pass. Could this be a bug in Edge

model validation across multiple views
I have a rather complex object with a number of attributes. For a variety
of reasons, I would like one view to create the object with only a couple of
fields completed, then a second and third view to finish all the fields. I
would like the model to validate_presence_of all these fields, since
eventually I need them all there, and I would like each page to validate its
portion of the fields that

Validating an ActiveRecord object and its has_many :through associations
Considering an object with several has_many :through => associations,
what is the ''best'' way to handle validations?
As an example:
class Student < ActiveRecord::Base
# some attrbutes like
# :name
# :grade
# relationships
has_many :students_assignment, :dependent => :destroy
has_many :assignments, :through => :students_assignment

confused about ActiveRecord relationships
I am very confused about where to put the belongs_to and the has_one
(and other relationship identifiers). I have read the RDoc and the
agile book many times about this and I think i still see it backwards.
Let me outline my app so you have an understanding...
I have 2 tables:
Schools { id, school_name, address_id }
and
Addresses { street1, street2, city, state, zip, country }

Controllers, Models, and Validations...
Hello,
After listening to DHH''s 2006 RailsConf keynote, I decided to take a
leap on my current application and do a little more re-organizing to
make it more CRUD-based. As such, I ended up changing some things
around to get this (simplified):
User has_many :enrollments, :conditions => ''status > 0''
User has_many :schools, :through => :enrollments

Easy way to handle form input without a model class?
I have a couple forms that I''d like to be able to validate and
automatically populate, but it shouldn''t be based on AR. In fact I
often have a bunch of small forms that I can''t really justify writing
a whole new model class for anyway. I''d like to validate the form
input, and then use rails helpers to automatically populate the form
if validations fail.

Something is getting lost here.

end
def show

Using :include "recursively" (including the children of the child)?
Hi,
Let''s say I have the following hierarchy of tables:
Group <- parent
Location <- child of Group
School <- child of Location
Phone <- child of School
Then, if I want to do this:
Location.find(...someparms..., :include => [:schools, :group, :phones])
I get an association error (Association was not found). I guess it
happens because AR is looking in the Location model
