我有这个方法：
@api.multi
def create_print(self,vals):
rec_production_order = self.env['bsi.production.order'].search([], order='id desc', limit=1)
self.env['bsi.print.order'].create({
'origin': rec_production_order.name,
'state': 'draft',
})
if order_lines in rec_production_order:
vals.update({'order_lines':[(0,0,
{
'isbn':'isbn',
'qty':'consumed_qty',
})]})
return super(bsi_print_order,self).create(vals)
此方法位于'bsi.production.order'对象上，这些是我使用的对象：
class bsi_production_order(models.Model):
_name = 'bsi.production.order'
_inherit = ['product.product']
@api.model
def create(self, vals):
if vals.get('name', 'New') == 'New':
if vals.get('production_type') == 'budgeted':
vals['name'] = self.env['ir.sequence'].next_by_code('bsi.production.budgeted') or '/'
elif vals.get('production_type') == 'nonbudgeted':
vals['name'] = self.env['ir.sequence'].next_by_code('bsi.production.non_budgeted') or '/'
elif vals.get('production_type') == 'direct':
vals['name'] = self.env['ir.sequence'].next_by_code('bsi.production.direct') or '/'
return super(bsi_production_order, self).create(vals)
name = fields.Char('Reference', required=True, index=True, copy=False, readonly='True', default='New')
date = fields.Date(string="Production Date")
notes = fields.Text(string="Notes")
order_lines = fields.One2many('bsi.production.order.lines', 'production_order', states={'finished': [('readonly', True)], 'cancel': [('readonly', True)]}, string="Order lines", copy=True)
print_orders = fields.One2many('bsi.print.order', 'production_orders', string="Print Orders")
class bsi_print_order(models.Model):
_name = 'bsi.print.order'
_inherit = ['mail.thread','mrp.worksheet.contract']
name = fields.Char('Reference', required=True, index=True, copy=False, readonly='True', default='New')
date = fields.Date(string="Print Date")
production_orders = fields.Many2one('bsi.production.order', ondelete='cascade', string="Production Order")
origin = fields.Char(string="Origin")
due_date = fields.Date(string="Due Date")
state = fields.Selection([
('draft','Draft'),
('awaitingraw','Awaiting raw materials'),
('wip','Work in Progress'),
('delivered','Delivered'),
('cancel','Cancel'),
], string="State")
notes = fields.Text(string="Notes")
class bsi_print_order_lines(models.Model):
_name = 'bsi.print.order.lines'
print_order = fields.Many2one('bsi.print.order', string="Print Order")
production_orders = fields.Many2one('bsi.production.order', ondelete='cascade', string="Production Order")
isbn = fields.Many2one('product.product', string="ISBN", domain="[('is_isbn', '=', True)]")
qty = fields.Integer(string="Quantity")
consumed_qty = fields.Integer(string="Quantity consumed")
remaining_qty = fields.Float(string="Remaining quantity", compute="_remaining_func")
state = fields.Selection([
('draft','Draft'),
('inprogress','In progress'),
('readytomove','Ready to move'),
('intransit','In transitt'),
('done','Done'),
], string="State")
is_book_block = fields.Boolean(string="Is Book Block Done")
is_binding = fields.Boolean(string="Is Binding Done")
is_edging = fields.Boolean(string="Is Edging Done")
@api.onchange('qty', 'consumed_qty')
def _remaining_func(self):
if self.consumed_qty or self.qty:
self.remaining_qty = self.consumed_qty - self.qty
我想将bsi.production.order中当前表单中的记录传递给bsi.print.order和bsi.print.order.lines，每次点击上面提到的方法时我都会将其记录下来：

有什么想法吗？
答案 0 :(得分：1)
首先，如果从按钮调用此方法，则无需获取任何记录 因为self（RecordSet）只包含该记录，但它更好 如果要在使用odoo-API时调用此方法，则以任何方式循环。
def @api.multi
def create_print(self,vals):
# first define the empty model to call create from
copy_record = self.env['other.model'] # now you call the method directly
for record in self:
# like this is safer
# here create a list of cammands for you new o2m_field
o2m_field = []
for rec in record.o2m_field:
# here loop through all o2m record to create the list of commands
o2m_field.append(
(0,0,
{
'some_field': rec.some_field,
'some_field2': rec.some_field2,
'some_m2o_field': rec.some_m2o_field.id,# m2o pass interger value
# hope you don't have o2m_field here too. or you need to use imagination to create
# a good method that creates this list of commands.
}
)
# now create the record
copy_record.create(
{
'simple_field' : record.simple_field, # for simple field type char,date,...
'm2o_field': record.m2o_field.id, # pass the id always
'o2m_field': o2m_field, # here we pass the list of commands that we created earlier
})
我认为你有这个想法复制一个记录是一个非常复杂的操作，特别是当副本中有m2m和o2m字段时。
