Instance Method Details

#find(*args, &block) ⇒ Object

Pure pass-through plus wrapping. The argument list is NOT re-declared, so the driver keeps deciding what find accepts.

def find(*args, &block)
  MongoView.new(__getobj__.find(*args, &block))
end

#find_one(filter = nil, projection = nil) ⇒ Object

pymongo's signature, which the Python master already ships. On the driver a projection is an OPTION rather than a positional, so it is spelled the driver's way here; the meaning is identical.
