[15.0][FIX] mrp_project: assign parent MO project to child MO

[IriaAlonso]

When a project is modified in a MO that has child MOs, the changes are automatically applied to those child MOs as well.

This only happens if the child MOs already exist;
if they are generated later, the changes are not applied. This fix resolves that issue.

Some minor suggestions

Suggested change

	@api.model
	def create(self, values):
	production = super().create(values)
	if production.origin:
	production.project_id = self.env['mrp.production'].search([("name", "=", production.origin)]).project_id
	return production
	@api.model_create_multi
	def create(self, vals_list):
	for vals in vals_list:
	origin = vals.get('origin')
	if origin:
	vals['project_id'] = self.env['mrp.production'].search([("name", "=", origin)]).project_id.id
	return super().create(vals_list)

Could you try this if it gets same result?

	@api.model
	def create(self, values):
	production = super().create(values)
	if production.origin:
	production.project_id = self.env['mrp.production'].search([("name", "=", production.origin)]).project_id
	return production
	@api.model
	def create(self, vals_list):
	origin = vals_list.get('origin')
	if origin:
	vals_list['project_id'] = self.env['mrp.production'].search([("name", "=", origin)]).project_id.id
	return super().create(vals_list)

In this way, we would get the same result

This code should be properly protected. As we know, _get_sources() could return more than one MO, then production._get_sources().project_id could return a recordset with two or more project, an this code could raise an error. Better try this (not tested, we inspect of only one project is available before assigning it):

Suggested change

	if production._get_sources():
	production.project_id = production._get_sources().project_id
	project_ids = production._get_sources().project_id
	production.project_id = (
	len(project_ids) == 1
	and project_ids
	or False
	)
