Question

I want to remove all embedded documents from a collection, but I can’t figure out how to do that.

I have tried a few ways, but I think this one should work:

Products.update({_id: data._id}, { $pull : { orders : {$gte: 0} } });

Products is the collection, orders is the array with embedded documents.

Remove all orders where the index is greater or equal than 0.

No luck.

Try this

db.products.update({_id: data._id},
                   {$unset: {orders: 1}})

or this

db.products.update({_id: data._id},
                   {$set: {orders: []}})
