Open For Small Business

In OpenERP, if you have spent any time at all writing mods you will be used to something like this

prod_obj.action_update_cost(cr, uid, product_id, context)

to call a method of an object, passing the cursor, user id, product_id and context.  Also you have probably done something like this

sale_order.order_line.product_id

to obtain a browse record, or even appended .id to get the id of the object for passing in the above orm_pool function.

Well, as it turns out there is another way, and you can call these methods directly, and without arguments, so for example

sale_order.order_line.product_id.action_update_cost()

Then the ORM works out the arguments for you.  I kind of worked this out from some write calls I had seen in workflow, but to date have had no problems using it with any function with a standard signature.
