从odoo中导出Excel

利用xlwt生成Excel，与生成文件不同的是跳转到URL进行下载。

sio = StringIO.StringIO()
wkbook.save(sio)
records[0].xls = sio.getvalue()

return {
    'type': 'ir.actions.act_url',
    'url': '/web/binary/download_document?model=shop.reg&field=xls&id=%s&filename=%s.xls' % (records[0].id, records[0].shop_name),
    'target': 'self',
}

然后在controller中返回正常的respone:

@http.route('/web/binary/download_document', type='http', auth="public")
@serialize_exception
def download_document(self,model,field,id,filename=None, **kw):
    """ Download link for files stored as binary fields.
    :param str model: name of the model to fetch the binary from
    :param str field: binary field
    :param str id: id of the record from which to fetch the binary
    :param str filename: field holding the file's name, if any
    :returns: :class:`werkzeug.wrappers.Response`
    """
    export = request.env[model].sudo().browse(int(id))
    filecontent = export.xls
    if not filecontent:
        return request.not_found()
    else:
        if not filename:
            filename = '%s_%s' % (model.replace('.', '_'), id)
        return request.make_response(filecontent,
                        [('Content-Type', 'application/octet-stream'),
                            ('Content-Disposition', content_disposition(filename))])
