I'm trying to prevent merb from making so many queries. When
I .to_yaml an Order It does a query for every row in the order, which
seems rather redundant to me. I can't find a good example of eager
loading so I would appreciate either some advice or some information
on how to get it going in my situation :)
Thanks much :)
Here is my basic data structure:
Order
Product
Order_Products (order_id, product_id)
My controller is something like this:
...
def index
@test = Order.get(:limit => 5)
display @test
end
...
My view:
...
- for test in @test
%tr
%td
%pre
= test.to_yaml
= test.charges.to_yaml
...
# so when I do test.charges.to_yaml it does far too many queries
