instead of:
desired_keys = ['address' , 'zipcode' , 'city' , 'country']
local_array = session_user.attributes.select{|key,value| desired_keys.include?(key) }
local_hash = Hash[*local_array.flatten]

you can use:
# ‘name’, ‘id’ – fields that you don’t wanna to see in `local_hash`
local_hash = session_user.attributes.except(‘name’, ‘id’)

means that the people using that application were located in different time zones , so using a single time zone as default in environment.rb was not a feasible idea .

Thank you.

config.time_zone = “Pacific Time (US & Canada)”

Also I couldn’t understand by what you meant by:
“And the tricky part is, it was different for different environments. “

in my initializer i will have

class ActiveRecord::Base

private

# your code

end

class User
attribute_method_affix :prefix => ‘is_’, :suffix => ‘?’

private

def is_attribute?(attribute)
send(attribute).present?
end
end
