[dingwf]

PyMongo 4.x aready remove ensure_index(), should use create_index() or create_indexes().

The same problem, doesn't work with MongoDB.
TypeError: 'Collection' object is not callable. If you meant to call the 'ensure_index' method on a 'Collection' object it is failing because no such method exists.

Is it correct code?

app = Flask(__name__)

client = MongoClient("mongodb://mongodb:27017/")
db = client["mydatabase"]
collection = db["mycollection"]

# Creating a uniqueness index for the "key" field
collection.create_index([("key", 1)], unique=True)

# flask-profiler config
app.config["flask_profiler"] = {
    "enabled": app.config["DEBUG"],
    "storage": {
        "engine": "mongodb",
        "MONGO_URL": "mongodb://mongodb:27017/",
        "DATABASE": "mydatabase",
        "COLLECTION": "mycollection",
    },
}
