===============
Onchange Helper
===============
This is a technical module. Its goal is to ease the play of onchange method directly called from python file.
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_onchange(vals, ['partner_id'])`
Then, `vals` will be updated with partner_invoice_id, partner_shipping_id, pricelist_id, etc...
