I''m using the fields_for helper with accepts_nested_attributes_for
The System model has_many children.
If I do this in my haml template:
-form_for @system do |s|
=s.text_field :name
-s.fields_for :children do |child_fields|
=child_fields.text_field :name
all is fine. The fields_for iterates over all children and puts the
correct data in the fields.

fields_for weirdness
I just did a large upgrade to to Rails 2.3.4 and I am trying to make
use of the more modern view features.

Best way to instanciate an empty address element in many nested fields_for
Hi!
I have 3 models, User, Company and Address.
Basically, a User belongs to a Company and an Address has one Company
(because it can be linked to other models).
In a form I want to display a User, its Company and its company Address,
with fields_for.
The problem is when my User has a Company, that does *not* have an Address:
the part containing the Address is not displayed.

Are there other examples of how this works anywhere?

Am I wrong or is fields_for not working right in Rails 2.2.2
I may be totally wrong about what the fields_for method is supposed to
do, but for some reason I thought using it scoped an object around an
association.
For example, I have a User class and when you''re creating a new user I
want to use fields_for to add a BillingAddress to the user like so:
<%- fields_for :billing_address do |billing_address_form| -%>
<%= render :partial

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

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

how to set up fields_for to choose a subclass?
I have an STI model where UtilityProvider is the parent class, and
there''s a sub-class for each specific utility provider.
When the user goes to choose a UtilityProvider, I want to present a
pull-down list of UtilityProvider.subclasses (or, more likely, a
filtered version of that), and when the user hits [submit] to create the
appropriate subclass.

Nested forms without looping through fields_for collection.
Hi,
I have a fairly complex form and I am wondering if it is even possible
to do what I am attempting.
I have multiple models included in the form. A small example would be
the following:
Company has many Locations
Company has many PhoneNumbers... and so on
I have this working without issue using Rails 2.3 and nested forms.
Where this becomes complex is that I also have another model named
