Rails console, wierd issue

Question

I type the following:

>> x.inspect
"\"53219847091d6601dd000004\""

>> "53219847091d6601dd000004".inspect
"\"53219847091d6601dd000004\""

 >> "53219847091d6601dd000004"==x
 false

They are the same so why they are not equal to each other?

Answer 1

inspect returns a string representation of your object, its implementation is up to the class:

class Foo
  def inspect
    "I'm Foo"
  end
end

class Bar
  def inspect
    "I'm Foo"
  end
end

foo = Foo.new
bar = Bar.new

foo.inspect
#=> "I'm Foo"

bar.inspect
#=> "I'm Foo"

foo and bar have the same inspect value, but they are not equal:

foo == bar
#=> false

In fact, they are totally different objects:

foo.class #=> Foo
bar.class #=> Bar
