Question

Is there any one command in Mongoid to delete an object using id?

Something like,

ClassName.delete(:id)

Currently i dont see anything like that and im using,

obj = ClassName.find(:id)
obj.delete

Can it be any better?

Answer 1

You can do something like the following:

ClassName.delete_all(conditions: { _id: BSON::ObjectId("whatevertheidis")})

You need the underscore in _id or it won’t work.

Also, it may not matter, but destroy_all will run the model’s callback methods while delete_all does not.
