How do I write $slice MongoDB code in golang? Here is my MongoDB code:
db.userdetail.aggregate([{"$project":{"user":{"$slice":["$user",2,1]}}}]).pretty()
I try to write this code in golang:
o1 := bson.M{
"$project":bson.M{"user":bson.M{"$slice":bson.M["$user",2,1,],},},
It gives me the following err: syntax error: unexpected comma, expecting ]
bson.M is map[string]interface not slice. And you need []interface for "$slice".
o1 := bson.M{"$project": bson.M{"user": bson.M{"$slice": []interface{}{"$user", 2, 1}}}}
If you share some dummy data, input and output, I could help you further.
