Delete by id in mongoid

Question

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

Something like,

ClassName.delete(:id)

I currently don't see anything like this and use im,

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

What could be better?

Another way

ClassName.any_in(:_id => ["id1", "id2"]).destroy_all

You can do something like the following:

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

You need to underline the symbol _id

or it won't work.

Also, it may not matter, but destroy_all

will trigger the callback methods of the model and delete_all

not.
