How to delete document from MongoDB using Mongoengine?

Question

How to delete document from MongoDB using Mongoengine? I'veread the API reference here:
http://docs.mongoengine.org/apireference.html
but I can not understand what is:

delete(**write_concern)

Do you have any idea?

I don't know mongoEngine, but i Think that Write concern is docs.mongodb.org/manual/core/write-concern and fsync: True i think that force write on primary ( journaled ) — Barno

You can either delete an single Document instance by calling its delete method:

lunch = Food.objects.first() // Get a single 'Food' instance
lunch.delete() // Delete it!

Or you can delete all items matching a query like so:

Food.objects(type="snacks").delete()

You may also want to use lunch = Food.objects.get() if you expect one and only one document to match the query (typically request by ID).

U can use the mongoshell and issue the following command:

db.collection.remove({your condition on documents you want to remove})

for example: From food collection you want to remove all the food which has type snacks. then you can issue the following command:

db.food.remove( { type : "snacks" } )
