Push to two separate arrays in one update call in mongodb
I am trying to update to update two separate arrays in a document with one update call. Is there a way to do this?
For example if I have a document like:
{
_id:1,
array1:[1],
array2:[4]
}
right now i am doing this:
db.collection.update({_id:1},{$push:{array1:"2"}})
db.collection.update({_id:1},{$push:{array2:"5"}})
Is there a way to reduce this to just one call? I have tried just passing an array to push, i have tried multiple push statements in update object but those don't work. Thanks for your help with this!
Solution 1:
You can specify multiple fields to the $push
operator
db.collection.update(
{ _id :1 },
{ $push : { array1 : "1", array2 : "5" }}
)
