Model associations

How does Active Record determine what tables to use when you define an
association? For example

class Order < ActiveRecord::Base
has_many :orderItems
end

class OrderItem < ActiveRecord::Base
belongs_to :order
end

Then in a view you use the association name:

@order[0].orderItems.each {|line| puts line.item_id + " - " +
line.name}

It turns out that you can also use the names “order_items” or
“Order_Items” instead of “orderItems” and that works fine. I would
expect one or the other to work but not both.

Is ambiguity this by design?

Which should be used according to best practice?

Rubyists usually use CamlCase for ClassNames. Personally, I
prefer :order_items for symbol names. But, the great thing is you
get to use whatever you want!
