Unexpected end of input?

Question

in the following code I am running into an error which states syntax error, unexpected '\n', expecting :: or '[' or '.' (SyntaxError) But I don't see where the issue is.

module Xaaron
  class ApiKey.class_eval # It does not like this....
     include Promiscuous::Publisher
     publish :xaaron_users_id, :api_key, :as => :ApiKey
  end
end

Am I using class_eval wrong?

Answer 1

You can either remove the class keyword, and add do after calling class_eval (passing it a block):

module Xaaron
  ApiKey.class_eval do
     include Promiscuous::Publisher
     publish :xaaron_users_id, :api_key, :as => :ApiKey
  end
end

(given that ApiKey already exists)

OR you can remove the class_eval altogether:

module Xaaron
  class ApiKey
     include Promiscuous::Publisher
     publish :xaaron_users_id, :api_key, :as => :ApiKey
  end
end

This will work even if the ApiKey already exists... that's just the way ruby works...
