Help me understand why I get this error when I click on delete:
Cannot read property 'remove' of undefined I am just learning. maybe something in the code.
used Mongoose :
router.delete('/contacts/:id', function(req,res){ Contacts.findById(req.params.id, function(err, user){ if(err){ res.send({message: "Error" + err}) } user.remove(function(err){ if(err){ res.send(err) } res.send({message: "Delete"}) }) }) })
