Mongodb Pymongo remove fields from documents

Question

My idea is to remove certain data updated earlier on certain conditions. For that I cant update documents with any null/None value. That should not going to happen in Mongodb. As a workaround, I am got to use $unset in MonngoDB. The docs says, here that we can pop a field from a document using $unset . like this

db.collections.update({ id: uid }, { $unset: [ "<field1>", "<field2>", ... ] })

My question is this. How can we achieve this with Pymongo.?

Answer 1

Pymongo is generally similar to the mongodb shell commands, but it has to work within the constraints of the python syntax. Importantly, you must put the $ operators in quotes, so "$unset" as per below.

db.collections.update_one({ "id": uid }, { "$unset": [ "", "", ... ] })

If this doesn't work, post the error you are getting.
