I'm a bit unclear what's going on with relations. I'm hoping someone can help explain it to me.
Lets say we have a model with orders and line_items such that an order has many line_items. Thus: class Order has_may :line_items end class LineItem belongs_to :order end When I have an order and call line_items what's going on? e.g. Order order = Order.first order.line_items.each {|li| puts li } I thought that was basically an alias for: Order order = Order.first LineItem.where(:order_id => order.id).each {|li| puts li } but, this isn't consistent with batching. So if we do Order order = Order.first # this doesn't appear to work, it's not batching, just finding all of the line items and iterating order.line_items.find_each {|li| puts li } # this seems to work as expected (i.e. it batches the retrieval from the db) LineItem.where(:order_id => order.id).find_each {|li| puts li } Can anyone explain to me why these to are different? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
