1.检查业务逻辑中的错误，终止代码执行，显示错误或警告信息：
raise osv.except_osv(_('Error!'), _('Error Message.'))
示例代码：
#删除当前销售单，需要验证销售单的状态
def unlink(self, cr, uid, ids, context=None):
for rec in self.browse(cr, uid, ids, context=context):
if rec.state not in ['draft']:
raise osv.except_osv(_(u'警告!'),_(u'您不能删除以下状态的销售单 %s .')%(rec.state))
if rec.create_uid.id != uid:
raise osv.except_osv(_(u'警告!'),_(u'您不能删除他人创建的单据.'))
return super(sale, self).unlink(cr, uid, ids, context)
2.字段的 onchange 事件中返回值，同时返回提示信息：
warning = {
'title': _('Warning!'),
'message' : _('Warning Message.')
}
return {'warning': warning, 'value': value}
示例代码：
def onchange_pricelist_id(self, cr, uid, ids, pricelist_id, order_lines, context=None):
context = context or {}
if not pricelist_id:
return {}
value = {
'currency_id': self.pool.get('product.pricelist').browse(cr, uid, pricelist_id, context=context).currency_id.id
}
if not order_lines:
return {'value': value}
warning = {
'title': _('Pricelist Warning!'),
'message' : _('If you change the pricelist of this order (and eventually the currency), prices of existing order lines will not be updated.')
}
return {'warning': warning, 'value': value}
3.视图中 button 按钮点击时显示确认信息：
<button name="cancel_voucher" string="Cancel Voucher" type="object" states="posted" confirm="Are you sure you want to unreconcile this record?"/>
示例代码：
<!-- This general view is used in
Invoicing - Journal Entries - Journal Vouchers -->
