MongoDB3 trouble with InsertMany

[germancmartinez]

Hi,

I´m having problems with the InsertMany method. I´m getting the error "MongoError: docs parameter must be an array of documents". I have tried putting the document array in the msg.payload and msg.payload.docs, but I'm always getting this error. Any help is welcome! Thanks!

when message payload is an array, each array element is interpreted as a parameter to the selected operation. eg when operation= "update", message.payload=[{surname:"smith"}, {"surname":"Smith"}, {"multi":true}]

since for you are wanting to supply an array as a single parameter, you should wrap it in a second array: message.payload=[[1,2,3,4]] and not message.payload=[1,2,3,4]

for insertMany ✗ msg.payload = [ { "name" : "Luffy" , "value" : 1} , { "name" : "Zoro" , "value" : 2 } ] ✓ msg.payload = [ [ { "name" : "Luffy" , "value" : 1} , { "name" : "Zoro" , "value" : 2 } ] ]

this is the correct format db.collectionname.insertMany([ {} , {} , {} ])

collectionname would be your collection u have created in ur database

{ } inside this your objects would be there eg:

try { db.products.insertMany( [ { _id: 13, item: "envelopes", qty: 60 }, { _id: 13, item: "stamps", qty: 110 }, { _id: 14, item: "packing tape", qty: 38 } ] ); } catch (e) { print (e); }
