MongoDB findAndModify() in vert.x 3 MongoClient

[Hitesh Aleriya]

Hello All,

I am using vert.x 3.0.0 with MongoDB 3.0.4 for my application. I read the official document of vert.x MongoClient but I didn't find any method like,  findAndModify(). MongoDB support this method, I want to update the collection and get back the updated value. I am unable to do this thing in vert.x. Can anyone have any idea around it or any alternative to achieve this. Please help me guys.

Thanks and Regards,

Hitesh

findAndModify is not implemented on mongo-client and the java mongo-driver-async 3.0.2 does not seem to have that functionality built-in, you might need to break your code in 2 parts:

1) find the documents
2) perform the update

From the driver it seems that there is a FindOneAndReplace/findOneAndRemove but the findAndModify seems to be more generic that these 2 methods...

hi, I think you can use:

def query = [

findAndModify: "table",

update: [ '$inc': [ "id": 1L ] ],

new: true,

upsert: false

];

mongo.runCommand("findAndModify", query, { result ->

}

by Groovy.
