pymongo collection.update command sometimes doesn't write to MongoDB

[Pouria Mojabi]

Hi Guys, 

My gratitude for the help in advance. 

I am using pymongo to push to MongoDB and I have a simple update command

res = db.user.update({"_id":ObjectId(userid)}, {'$set': {"blah":array}})

Even though "res" reports success, no data is pushed to MongoDB. I am very puzzled ... it happens one out of ten attempts 

Appreciate any thoughts

Thank you

When you say "res reports success" what are you referring to? If there was no error, and you have a document for "res", then the server processed the update. But that doesn't mean that the update actually modified any documents. What versions of PyMongo and MongoDB are you using?

So for some reason I wasn't notified of your reply, I apologize. Thanks for your help

I am using python 2.7 and Mongo 3.2.6 and pymongo 3.2

by res report success i mean, the document has the pushed data, but it is not reflected in mongodb

Please post reproduction steps (example data to update, the update call, the result document, and what you expect the result to be on the server side).
