Xml 如何在Openerp向导中编辑检索到的向导应答

我第一次碰巧遇到了这个Openerp向导，而且我知道一旦你点击“完成”按钮，你就不能编辑你保存的内容。 我需要做的是在检索向导后，使其在某些状态下可编辑

以下是我对该向导的调用，请帮助我使其可编辑

xml调用

 <button name="action_call_questions" string="Start" type="object" class="oe_highlight"/>

        if context is None: context = {}
        record = self.read(cr, uid, ids, [])
        record = record and record[0] or {}
