odoo16版本的render变更

今天在整理文件上传功能时，发现

odoo16的ir_ui_view.py中_render方法不见了，引用出错AttributeError: 'ir.ui.view' object has no attribute '_render'

    def _render(self, values=None, engine='ir.qweb', minimal_qcontext=False):assert isinstance(self.id, int)qcontext = dict() if minimal_qcontext else self._prepare_qcontext()qcontext.update(values or {})return self.env[engine]._render(self.id, qcontext)@api.modeldef _prepare_qcontext(self):""" Returns the qcontext : rendering context with website specific value (requiredto render website layout template)"""qcontext = dict(env=self.env,user_id=self.env["res.users"].browse(self.env.user.id),res_company=self.env.company.sudo(),keep_query=keep_query,request=request,  # might be unbound if we're not in an httprequest contextdebug=request.session.debug if request else '',test_mode_enabled=bool(config['test_enable'] or config['test_file']),json=json_scriptsafe,quote_plus=werkzeug.urls.url_quote_plus,time=safe_eval.time,datetime=safe_eval.datetime,relativedelta=relativedelta,xmlid=self.sudo().key,viewid=self.id,to_text=pycompat.to_text,image_data_uri=image_data_uri,# specific 'math' functions to ease rounding in templates and lessen controller marshmallingfloor=math.floor,ceil=math.ceil,)return qcontext

仔细一追，变的还不少

# 以下四行为与15引
import werkzeug, werkzeug.urls
from odoo.tools.json import scriptsafe as json_scriptsafe
from dateutil.relativedelta import relativedelta
from odoo.tools.image import image_data_uri

AttributeError: 'ir.ui.view' object has no attribute '_render'

以后用到render方法时只用借用新的
