Having issues saving line items to the DB

really simple, but I''m been googling and reading for a day and have made
zero progress on it. Hopefully someone on this list can shine some light

counting rows via associations
Hi:
I have a table called clients and each client has many lists (a
has_many and belongs_to has been created in the class.
What I need to do is get a count of the rows in each list for each
client. I was hoping I could do something like
client.lists.count but it does not seem to work. Any suggestions?

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

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

Migrations problem with Agile Rails book

How to get a count of line_items
I am fairly new to Rails, and I am having difficulty in forgetting the
old way of developing and using the Rails way.
This is my question, using orders and line_items as an example.
An order has_many line_items
A line_item belongs to order
In my OrdersController I have
def summary
@orders = Orders.find(:all)
render :xml => @orders.to_xml()

What I want to achieve is to

How can one use GRUFF with locomotive ( I guess there is a wider question here, also)
Hi:
I love Locomotive and use it exclusively for my rails projects. I''d
like to install GRUFF and give it a try (a graph image creation
package). I know I can do sudo gem install gruff from the command
line for normal ruby and rails. How do I make gems available to
Locomotive?

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 =

I don''t even know how to ask the question (4 lines of code)
I create a hash using this line of code @x = Account.find(:all)
I then want to go through each element in turn and add a key value
pair to the end of it. I thought this would work, but it does not.
@x.each do |a|
a.merge({"balance"=>50}
I used merge because I thought ''a'' would be a hash (how do you find
out the type of an object?)

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

Cloning a one-many association
Hi, I want to make a copy of an object with its associations, and I am
looking for an elegant solution. This is what I intuitively think should
work, but it doesn''t:
order2 = order1.clone
order1.line_items.each do |o|
order2.line_items.build(o)
end
This doesn''t work because a model class does not stringify its keys ...
so I can''t pass an object into a method that

Nil being coerced to float
I was doing this:
@line_items = LineItems.find_all_by_invoice_id(params[:id])
@payments = Payments.find_all_by_invoice_id(params[:id])
@total = @line_items.sum{ |item| item.cost }

@balance = @total - @payment_total
But when no payments had been made it was coming up with an error when

Question about using DISTINCT in ActiveRecord find method.
Hi,
Am relatively new to the RoR world. My question is quite simple.
I have a query like such:
shipmentNumbers = Order.find_by_sql(["select distinct s.id from orders
o, line_items li, shipment_lines sl, shipments s where o.number=? and
o.id = li.order_id and li.id = sl.line_item_id and sl.shipment_id =

DB trigger vs before_create
Hello everyone,
I''m having trouble figuring out which approach is better.
I have the following tables: products, orders and line_items.
Every time an Order is placed, the quantity field in the products
table has to be updated for each LineItem in the Order. One option is
to use DB triggers which is not as portable as using before_create in
the Order model. But with before_create I cannot
