无法使用pymongo使用django删除Mongo索引
我有一个简单的模型，定义为（sample_app/models.py）： 然后我就跑无法使用pymongo使用django删除Mongo索引,django,mongodb,pymongo,django-database,djongo,Django,Mongodb,Pymongo,Django Database,Djongo,我有一个简单的模型，定义为（sample_app/models.py）： 然后我就跑 python3 manage.py makemigration sample_app 迁移被创建。跑步 python3 manage.py migrate sample_app 迁移已成功执行 我登录到mongo shell并检查了索引： db.collectino_name.getIndexes() Output--> [ { "v" : 2, "key" : { "_id" :
python3 manage.py makemigration sample_app
python3 manage.py migrate sample_app
db.collectino_name.getIndexes()
Output-->
