How to drop index using Mongoose

问题

Mongoose

Imagdata.dropIndexes( { "image_id": 1 }, function(err){
         if(err){
             res.send("error");
        }
        else{
            res.send("success");
        }
});

This is the code I used for remove the index of a field 'image_id'. When I trying to execute this function It shows "TypeError: Imagdata.dropIndexes is not a function". How to fix this issue...

You need to use the raw collection property of your model to access the underlying MongoDB API:

Imagdata.collection.dropIndex(...);
