                      QUESTION

                      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({ message.author.id });, everything finds, I checked with console log.

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

                      What could be the problem? Help me please!

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

                      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.

                      const Marry = mongoose.model('Marry', marrySchema);
                      const exists = Marry.findOne({ message.author.id });
                      const married = Marry.findOne({ userToMarry.id });
                      

                      If that doesn't work, another thing you could try is making the findOne queries async inside the run method, like this:

                      const married = await db.collection("yourcollectioname").findOne({ message.author.id });
                      const exists = await db.collection("yourcollectioname").findOne({ userToMarry.id });
