如何显示 openerp 错误信息

Question

在我的学生模块中，我继承了 res.partner。如果合作伙伴是学生，我想限制在合作伙伴视图中修改名称。这是我的数据线。

from openerp.osv import osv, fields


class res_partner(osv.Model):
    _inherit = 'res.partner'
    _columns = {
        'name': fields.char('Name', size=250, required=True, select=True),
        'is_student': fields.boolean('Student', readonly=True),
}

def write(self, cr, uid, ids, vals, context=None):

    stud = self.browse(cr, uid, ids, context=context)[0]

    if ('name' in vals) & (stud.is_student is True):
        raise "Cannot Edit"
    else:
        return super(res_partner, self).write(cr, uid, ids, vals, context=context)

它正在运行，但我想在消息框中显示错误消息。也不例外。我该怎么做？

Answer 1

raise osv.except_osv(('Error'), ('Error  Cannot Edit'))

Answer 2

关于@Damian 的回答，osv.except_osv 在源代码中被标记为已弃用，但实际上并没有被弃用，因为它仍然存在于很多 Odoo 代码中。有更新的 openerp.exceptions.except_orm 和更新的警告。至少可以说是令人困惑。

还有，别忘了翻译。以except_orm为例。

from openerp.exceptions import except_orm
from openerp.tools.translate import _

raise osv.except_osv(_('Error!'), _("Something bad happened."))

或：

from openerp import _
from openerp.exceptions import Warning

raise Warning(_('Something bad happened.'))

Answer 3

查看 return 部分，这可能会对您有所帮助。

def check_partners_email(self, cr, uid, partner_ids, context=None):
        """ Verify that selected partner_ids have an email_address defined.
            Otherwise throw a warning. """
        partner_wo_email_lst = []
        for partner in self.pool.get('res.partner').browse(cr, uid, partner_ids, context=context):
            if not partner.email:
                partner_wo_email_lst.append(partner)
        if not partner_wo_email_lst:
            return {}
        warning_msg = _('The following contacts have no email address :')
        for partner in partner_wo_email_lst:
            warning_msg += '\n- %s' % (partner.name)
        return {'warning': {
                    'title': _('Email addresses not found'),
                    'message': warning_msg,
                    }

Answer 4

您甚至可以将警告与要在输入字段中设置的替代值结合起来，如下所示：

   if not start_date < end_date:
       return {
           'warning': {
               'title': _('Warning'),
               'message': _('End date must be bigger than start date'),
           },
           'value': {
               'elec_end_agreement':
                   self.get_end_date(cr, uid, pp_id, start_date)
           },
       }
