One To Many To Many
Hey all,
I''m trying to find a simple way to reference all of the objects that
belong to their parent''s parent. In other words:
Clients --> Orders --> LineItems
How do I get all of a client''s lineitems in one array (i.e.,
client.all_lineitems)?
Thanks!
-Neal

Decimals are being converted to Bigdecimals!!!!!
Hi all,
I''m working on a financial app, and have set up some columns in my

Saving one-many associations (elegant solution please)
What is the most elegant way to save new one-many associations?
order = Order.new(:name => "My Order")
order.line_items << LineItem.new(:product_id => 1, :quantity => 2)
order.line_items << LineItem.new(:product_id => 2, :quantity => 5)
order.save
The above - which is by far the most elegant way of putting it - doesn''t
work for me - the line_items

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}

How to test views with Nested Resources and Partials
Hi everyone,
I am relatively new to rspec and I am running into a wall in testing my
views. I have a RESTful resource Contracts with a nested resource of
Line_items.
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

How to deal with PayPal frauds?
I charge my customers through PayPal, but recently faced a fraud which
previously had only heard about. Somebody registered a few accounts, paid
online with paypal (as my service is only prepaid) and started making
expensive long distance calls. In fact the IP registering the accounts was
from Florida, and IPs making calls were from Africa. After about 20 minutes
the first payment was reversed.

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

Preventing Double Submit?
Hi,
I have a sensitive submit button that does a separate credit card
payment post in the controller action, which could take ~2 seconds. I
want to ensure that if the user double clicks on it, that the controller
won''t do two payments. Right now, I do a redirect after the payment
succeeds, so a refresh of the page won''t cause a problem but I am
worried about multiple requests
