Onchange Helper
===============
This is a technical module. Its goal is to ease the play of onchange method directly called from Python code.
Usage
=====
To use this module, you need to:
* depend on this module
* call `yourmodel.play_onchanges(values, ['field'])`
Example if you want to create a sale order and you want to get the values relative to partner_id field (as if you fill the field from UI)
`vals = {'partner_id': 1}`
`vals = self.env['sale.order'].play_onchanges(vals, ['partner_id'])`
Then, `vals` will be updated with partner_invoice_id, partner_shipping_id, pricelist_id, etc...
You can also use it on existing record for example:
`vals = {'partner_shipping_id': 1}`
`vals = sale.play_onchanges(vals, ['partner_shipping_id'])`
Then the onchange will be played with the vals passed and the existing vals of the sale. `vals` will be updated with partner_invoice_id, pricelist_id, etc..
Behind the scene, `play_onchanges` will execute **all the methods** registered for the list of changed fields, so you do not have to call manually each onchange. To avoid performance issue when the method is called on a record, the record will be transformed into a memory record before calling the registered methods to avoid to trigger SQL updates command when values are assigned to the record by the onchange
