mongodb

问题 I'm trying to find the best way to implement authorization. At this time, only thing I need is a simple free account, but later I may include user roles for a "premium" account using a payment system like stripe. I have already started reading and experimenting with Auth0 but then found some other ways I can do it.

问题 I am working on a flask app and using mongodb with it. In one endpoint i took csv files and inserts the content to mongodb with insert_many() . Before inserting i am creating a unique index for preventing duplication on mongodb.

问题 I am having a spring boot application which exposes REST APIs and also am planning to add a spring boot scheduled task. The purpose of task is to pick up some pending 'reservations' from data store which is momgodb and process it. Now the question is when multiple instances of service running, there is high probability all the nodes will pick up same 'reservation records'. I was looking at mongodb lock for this and was checking updateAndModidy / transactions (in 4.x) of mongodb. Also

问题 Im using node with mongo, and I want for the mongo get call to stop returning some values, such as _id and uid. Everything that ive read says that this call should work, but when I print the json value on my UI, it still has those values. app.get('/users', async function(req, res){ console.log("Getting User Info!"); await client.connect(); const db = client.db('database'); var uidparam = req.header("uid"); db.collection("users").findOne({"uid": uidparam}, { _id: 0, uid: 0, }, function(err,

问题 I am trying to create a admin user. I've tried several different ways. I realize that authorization is enabled , and if I turned it off, then back on it would allow me to create the first user. However I am trying to create the first user while authorization is enabled . I have wiped the data directory and I am dealing with a fresh database. I've been able to use rs.initiate() and db.createUser() from the console, but what I'm discovering is that it's impossible for me to run a script that
