Does MongoEngine have an "AutoField()" like Django?-CodePudding

I just switched from SQL to MongoDB. When I was changing all my model fields from Django fields to MongoEngine fields, I realized there was no AutoField(). Does anyone know a substitute for this?

CodePudding user response：

You can use ObjectIdField of mongodb like this:

from bson import ObjectId
from mongoengine import Document, ObjectIdField

class ModelName(Document):
    id = ObjectIdField(primary_key=True, default=ObjectId)

and create your object in the model like this:

obj_doc = ModelName.objects.create(field1='value1', field2='value2')

then if want to check id of your object:

print(obj_doc.id)

here id of obj_doc will be created automatically.
