QWEB：

Could not render element 'div' The error occured while rendering the template 900 

<div class="input-group"> 
                 <div t-field="odss_sale_order.order_date"/></div> 

何が問題であり、私はそれをどのように修正するのですか？事前に

おかげで、 ハムザTahboub

Answer 1

あなたがPYファイルのあなたの一番上にこの行をadddingでみました。

from openerp import models, fields, api, _

が、これはそれを解決することを願っています。

ありがとう、 Chandni。
