If I input the following in the challenge it does not pass
class Person < ActiveRecord::Base
scope :hamptons, -> { where("first_name = ?", "Hampton") }
end
Has anyone got an idea why this is wrong? If I use the hash-method it works fine.
class Person < ActiveRecord::Base
scope :hamptons, -> { where(:first_name => "Hampton") }
end

Courses Plus Student 55,489 PointsYes it uses an array in the first and a hash in the second version but, as I understood it:
in the array condition ActiveRecord will take the second element "Hampton" and replace the question mark in the first element of the array with it, which is equivalent to saying find all instances where first_name is Hampton, i.e. first_name must equal "Hampton"
in the Hash condition we use the field we want to find as the key and set the value to the condition it needs to satisfy, essentially we are saying, apply whenever first_name is Hampton, i.e. first_name must equal "Hampton"
so while we can use the hash method, and yes an array is not a hash, isn't the logic behind both statements the same? so unless I am not overlooking a typo, shouldn't both statements pass?
with alternate syntax I mean a pure string, array and hash condition should all be possible in this case, or am I missing something?

Courses Plus Student 55,489 PointsThat is possible. Although I might be totally wrong or overlooking something. It has happened ... occasionally. So therefore I thought I'd ask :0)
