Instance Method Details

#==(other) ⇒ Object

Public: Overrides == to compare via class and entity id.

Example

movie = Movie.find(1234)
movie.to_key
# => 'movie-1234'

Returns a string representing the unique key.

def eql?(other)
  self == other
end

#hash ⇒ Object

Public: Hashes our unique key instead of the entire object. Ruby normally hashes an object to be used in comparisons. In our case we may have two techincally different objects referencing the same entity id, so we will hash just the class and id (via to_key) to compare so we get the expected result

Returns a string representing the unique key.
