I'm trying to get up to speed on sequel but I'm not having much luck
with the mechanics of the one_to_many association. Thanks for any
insight you might provide:
I'm trying something like this (using a legacy MS SQL database)
class Order < Sequel::Model(:Order)
one_to_many :items, :key => :Order, :class => :OrderItem
end
class OrderItem < Sequel::Model(:OrderItem)
many_to_one :order, :key => :Order, :class => :Order
end
Table Order doesn't have a OrderItem column, which I think is pretty
common for these kind of situations. If you wanted to find all the
items for an order you'd have to query all items whose order key match
a specific order.
On to the part I don't understand: Who populates Order.items for a
specific Order: The association, or do I need to add code to do so?
The following code shows that items is an empty array (and my log
doesn't show any query for the items)
orders = Order.all
orders.each do |r|
items = r.items
puts "items is a #{items.class}"
pp items
end
