Invoice and invoice_lines
Hello People,
I have a possibly very lame question.
I am fairly new to RoR, and I want to make sure I do it "right".
I have a model called Invoice, and one called InvoiceLines. Usual story:
the table "invoice" has a 1:n relationship with "invoice_lines", which
includes invoice_id.
Now... the application will have a "new order" button, which will allow

Bug in rails ?
Hi !
I just have a simple question.
I am writing an app using rails to familiarize myself with the framework (which is pretty cool, by the way).
I just wanted to know why these two work differently (since "find" should be a synonym for "detect" according to the Pick Axe) :
current_item = @invoice.line_items.detect {|i| i.product.id == key}
current_item =

Adding extra field in form using ajax causes extra field to be overwritten, any way around that.
I''m having trouble when I try to add another field in the form using ajax.
I''m trying to add another line_item object into the invoice and i''m using
the link_to_remote function to implement this. When I do that though and
submit to the form, the line_item entries all have the same field name so
they get overwritten. I''m not sure how to get around that.

Validation dependent on unsaved parent
I''m having trouble with a validation that depends on an attribute of a
belongs_to parent. If the child is added to an unsaved parent
(parent.children << new child), the has_many collection
parent.children includes the unsaved child. However the belongs_to
attribute child.parent appears to be nil until the parent has been
saved. Without access to the parent attributes, the validation

How to check if a parent has children?
What is the new way to check if a parent has child items? In rails
1.2.6 I did this:
if @client.has_line_items?
Client being the parent and line_items the children.
Now that I have upgraded to rails 2.0.1 (on my way to current :-) ) I
am getting this message:
undefined method `has_line_items?'' for #<Client:0x7f3b093b01a0>
How should I format the query now?

How to test views with Nested Resources and Partials

I am trying to figure out how to test the "edit" form of the Line_items.
What complicates this is the nested routing and how to account for it,
and that there is a partial form (_form.haml) that both the edit.haml

DeliveryMethods in 1 single form.
And so I tried something like:
