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,

How To Spec Controllers with Finders
Given this code (which renders rjs), I''m faced with the fixture-
driven way of spec-ing or mocking. How the heck to you mock this so
the code at line (2) and (4) work right? I''m still struggling with
mocks but it seems like this can be done. Forgive the naivety of this
question.

Running total of a field in child records
What is the best way to get the running total of a number field in child
records. Let say I have an Order model, which has_many :line_items, and each
LineItem has an amount field. I would like to get the grand total of a
specific Order. Is it a good idea to add a ''total'' column in the ''orders''
table and update it every time a line_item is

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:

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.
