Question

在membership .py文件中，类account_invoice_line将继承＆＃39; account.invoice.line＆＃39; 并覆盖写入方法，当新的发票行时，将创建新的成员行在现有发票中创建。对我来说，当创建新的发票行时，它是不正确的在现有发票中，它必须与现有成员行相关，而不是创建新成员行所以我必须覆盖write方法，但始终执行member.py文件中的write方法的问题。所以有人可以告诉我如何覆盖write方法而不通过membership.fe文件中的write方法。这是files.py

文件中的代码

class account_invoice_line(osv.osv):
_inherit='account.invoice.line'

def write(self, cr, uid, ids, vals, context=None):
    """Overrides orm write method
    """
    member_line_obj = self.pool.get('membership.membership_line')
    res = super(account_invoice_line, self).write(cr, uid, ids, vals, context=context)
    for line in self.browse(cr, uid, ids, context=context):
        if line.invoice_id.type == 'out_invoice':
            ml_ids = member_line_obj.search(cr, uid, [('account_invoice_line', '=', line.id)], context=context)
            if line.product_id and line.product_id.membership and not ml_ids:
                # Product line has changed to a membership product
                date_from = line.product_id.membership_date_from
                date_to = line.product_id.membership_date_to
                if line.invoice_id.date_invoice > date_from and line.invoice_id.date_invoice < date_to:
                    date_from = line.invoice_id.date_invoice
                member_line_obj.create(cr, uid, {

account_invoice_line()

你可以绕过调用super方法，如下所示。

您需要传递osv.osv类来调用直接写入方法，而不是您的类名。

res = super(osv.osv, self).write(cr, uid, ids, vals, context=context)

它将绕过所有超级写入方法并直接调用osv.osv类。

注意：您也可以调用任何其他类而不是osv.osv。为此你必须遵循如下。

代表

from openerp.addons.account.account_invoice import account_invoice


class account_invoice_inherit(osv.osv):
def write( . .. . )

    res = super(account_invoice,self).write(. .. .)

    . .. .

    return res

这里从这个类系统中直接调用account_invoice类的写方法。

我希望它会对你有所帮助。

如何在不执行超级写入的情况下覆盖写入方法？
