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
