Question

Is there a way to automatically typecast values that are stored using ActiveRecord::Base.store?

Take this totally impractical example:

class User < ActiveRecord::Base
  store :settings, accessors: [ :age ]
end

user = User.new(age: '10')
user.age # => '10'

I know I can just override the reader method for age to convert it to an integer, but I was curious if there was an undocumented way of doing it.

Trying to avoid this:

class User < ActiveRecord::Base
  store :settings, accessors: [ :age ]

  def age
    settings[:age].to_i
  end
end

user = User.new(age: '10')
user.age # => 10

Update

Looking for something like:

class User < ActiveRecord::Base
  store :settings, accessors: {:age => :to_i}
end

Or:

class User < ActiveRecord::Base
  store :settings, accessors: {:age => Integer}
end

As of Rails 3.2.7 there is not a way to automatically typecast values. I’ll update this question if I ever come across a way to do it :/
