python - 在同一方法上传递对象字段和 one2many 字段 - Odoo v8

Question

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.product.order' 对象上，这些是我正在使用的对象:

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 中当前表单的记录传递到 bsi.print.order 和 bsi.print.order.lines，每次我点击上述方法时，它都会抛出:

Traceback (most recent call last):

有什么想法吗？

首先，如果您从按钮调用此方法，则无需获取任何记录因为 self (RecordSet) 将只包含该记录，但它更好如果您想在使用 odoo-API 中调用此方法，可以以任何方式循环。

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
        })

我认为您知道复制记录是一项非常复杂的操作，特别是当副本中也存在 m2m 和 o2m 字段时。
