Hmm....
I  will suggest to teach him in a reverse way.<p>Say, next time if he uses any of above statements like &quot;database not updating&quot; sorta...
Now you start asking him questions.... why is it now updating? Had you checked the connection is working?<p>Are you sending data to proper collection&#x2F;table. Is schema right?<p>And blah blah.....<p>I hope this kinda approach will develop his &quot;developer&quot; attitude in a small way.
Many new guys don&#x27;t get a chance to work and get mentored. He had got it.....Thanks to you! And also it doesn&#x27;t hurts to speak with him politely about this issue.
