javascript - updateOne deleting my data -

alright, i've been tinkering night , have sleep i'm asking here. why updateone deleting data when should updating it?

db.collection('users').updateone({"name":"bob"}, {"age":"20"}, (e,i) => {      console.log(i);  });

i.result.ok prints 1, when go search bob after doing this, data gone entirely, vanished.

my first question why happening, second how can update, since apparently isn't way it.

i can run find({"name":"bob"}) fine before hand, data exist before running this.

after, gone. please, blood pressure getting way high.

try following:-

you need use $set update specific fields. {} give blank, if there no find query.

db.collection('users').updateone({"name":"bob"},{$set: {"age":"20"} });

to answers, refer mongodb-update.

hope hep solving problem.
