            discord.js-commando enabling and working with mongodb
            Asked 2022-Apr-01 at 17:52

            I'm trying to create a discord bot, specifically the wedding team.

            I am using a MongoDB database. Now everything works and is saved, but there is one problem, the data is saved for the second and third rounds, etc.

            That is, the checks that I added do not work. I am trying to find data through const exists = Marry.findOne({ });, everything finds, I checked with console log.

            But when I try to validate it just doesn't work. if (exists == { return"You are already married!"); }

            What could be the problem? Help me please!

            Maybe instead userID: i just need to find for the value Is it possible?



            Answered 2022-Mar-31 at 16:07

            So I think you're having an async issue in your code. The query itself should work just fined. However, I suggest you move exists and married outside of run. Maybe paste them under the MongoDB connection and find a way to pass the message.

            Check your node version, if it's lower than 12 it won't work, if that's the case updating node should do do the job. You could downgrade your mongoose version too.

            There's an issue closed on Mongoose github page.



            Handling Database reconnections with MongoDB Native Driver in Node.JS
            Asked 2022-Mar-24 at 12:39

            With mongoose one can simply handle reconnections via connection-options:



            Answered 2022-Feb-23 at 14:30

            Wherever you've got the mongoose connection snippet from, it's outdated.

            The autoReconnect and auto_reconnect options were a thing in Nodejs native driver before v4.0, and mongoose just proxied these options to the driver.

            This is the documentation for the driver 3.7 with "autoReconnect" still there: and this is the commit where it's been removed:

            The option was "True" by default with a strong note to do not change this value unless you know exactly why you need to disable it.

            v4 introduced many changes to the driver - refactoring to typescript, architectural changes, you can see it from the commit, right. One of the changes affected connection logic and pool management. There is no option to disable reconnection anymore. It's always reconnects regardless how you connect directly or via mongoose.



            How to create a custom health check for Prisma with @nestjs/terminus?
            Asked 2022-Mar-11 at 22:26

            Since @nestjs/terminus doesn't provide a health check for Prisma, I'm trying to create it based on their Mongoose health check.

            When I try:



            Answered 2021-Oct-14 at 14:41

            A naive copy of the mongoose implementation isn't going to work because there are differences between the NestJSMongoose type/module and Prisma. In particular, getConnectionToken does not exist inside the Prisma package.

            I can't comment on what the best way would be to extend terminus to support prisma. You might have to dig a bit into the terminus interface for that. However, a simple way to get a health check/ping in Prisma is to use the following query:

            Answered 2021-Aug-28 at 07:49

            From the Mongoose 6.0 docs:

            useNewUrlParser, useUnifiedTopology, useFindAndModify, and useCreateIndex are no longer supported options. Mongoose 6 always behaves as if useNewUrlParser, useUnifiedTopology, and useCreateIndex are true, and useFindAndModify is false. Please remove these options from your code.



            How to fix the error (TypeError: Cannot assign to read only property 'map' of object '#')
            Asked 2022-Mar-05 at 09:40

            I am sending my data to MongoDB via Mongoose. Now, during the fetch of API route for it, an error is thrown.




            Answered 2022-Feb-11 at 00:32

            This issue occured recently and apparently its happening with latest version of node.

            So you can change the version of node to older version and it will be fixed. I am using node version v14.19.0

            Answered 2021-Aug-29 at 08:36

            ConnectOptions of mongoose for version 6.0.2 does not include useNewUrlParser, useUnifiedTopology, useCreateIndex. However, mongoose docs for 6.0.2 still shows those options to be valid and without those options, mongoose is throwing a topology error.

            Downgraded mongoose to version 5.13.8 and now it is working without problems.
