我有一个有很多字段和两个按钮的表单（保存并关闭和保存和新建）单击"保存和新建"按钮时，我希望显示以前输入的字段值。

好的，我的第一个解决方案（使用上下文）没有成功：-（但我尝试了另一种方式，我不太喜欢它，但它可以帮助你。

按照我的例子.py：

from openerp.osv import orm, fields
class object_one(orm.Model):
    _name = "object.one"
    _columns = {
                'name':fields.char('Name', size=128, required=True),
                'many_ids':fields.many2many('object.many',string="Many Objects")
                }
class object_many(orm.Model):
    _name = "object.many"
    _columns = {
                'name':fields.char('Name', size=128, required=True),
                'sel':fields.selection([('1','One'),
                                        ('2','Two'),
                                        ('3','Three')],
                                       string="Selection", required=True),
                }
    def _get_sel(self, cr, uid, context={}):
        many_id = self.search(cr, uid, [('create_uid','=',uid)], context=context, order="create_date desc", limit=1)
        if many_id:
            many = self.browse(cr, uid, many_id[0], context)
            return many.sel
        return False
    _defaults = {
                 'sel':_get_sel
                 }

按照我的例子.xml：

您将看到，用户创建的每个多对象都将从数据库获取最后一个选择（SEL）。 因此，它更像是针对您问题的解决方法。

希望这对你有帮助。
