Python 如何将自定义模型的字段值传递给Qweb报表？

我创建了一个向导，其中我放置了另一个模型中启用报表打印的manyOne字段[名称]。这里发生的事情是，当我选择一条记录并单击打印按钮时，它只打印空报告。因此，可以在这里将数据提取到报告中

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

    ob=self.pool.get('book.room')
    wizard=self.browse(cr,uid,ids,context=context)


    datas = {
         'ids': wizard.name,
         'model': 'book.room',
         'form': ob.browse(cr, uid, wizard.name)#[-1]
         # 'form': [{'create_uid': (1, u'Administrator'), 'create_date': '2015-10-20 10:32:42', 'name': (1, u'Nani'), '__last_update': '2015-10-20 10:32:42', 'date_end': '12/10/2015', 'date_start': "13/12/1201", 'write_uid': (1, u'Administrator'), 'write_date': '2015-10-20 10:32:42', 'display_name': u'Nani', 'id': 18}]
    }

    print datas.get('form')

    # print datas,'88888888888888'
    # print datas['form'],'9999999999999'

    return {
        'type': 'ir.actions.report.xml',
        'report_name': 'hotel_mng.Booking_Details',
        'datas': datas,
    }

提前谢谢

 class print_report(osv.TransientModel):
_name='report.wizard'
_columns={
    'room1':fields.many2one('hotel.allroom','roomnum','Room No.')
}
    def print_report(self, cr, uid, ids, context=None):
        current=self.browse(cr,uid,ids)
        obj=self.pool.get('book.room')
        k=obj.search(cr,uid,[('name','=',current.name.name)],context=context)


    context = {}
    data = self.read(cr, uid, ids)[0]


    datas = {
    'ids': k,
    'model': 'report.wizard',
    'form': data,
    'context':context
    }
    return{
        'type' : 'ir.actions.report.xml',
        'report_name' : 'hotel_mng.Booking_Details',
        'datas' : datas,
        } 

print_report()

上面的代码对我来说很好用。。它从参考模型中提取名称并打印报告，谢谢

def print_report(self, cr, uid, ids, context=None):
        datas = {}
        a=[]
        print "---------------------------------------------------------------"
        for phone in self.browse(cr, uid, ids, context=context):
            b=phone.selection_item
        print b
        if context is None:
            context = {}
        datas['ids'] = context.get('active_ids', [])
        datas['model'] = context.get('active_model', 'ir.ui.menu')
        datas['value']=b
        context.update({'names':b})
        return {

        'type': 'ir.actions.report.xml',
        'report_name': 'sales_invoice.report_mom',
        'datas': datas, 
        'context':context}

在报告中
