Class not getting initialized

[jayceef]

I have a normal class in my Rails 5 app:

class Routine < ApplicationRecord
belongs_to :user
end

irb: a= Routine.new(:elevation => 2343)
=> #<Routine:0x007ff2a19c2ea8
elevation: 2343

But when I add the Virtus gem the class doesn't get initialized:

class Routine < ApplicationRecord
include Virtus.model
belongs_to :user
attribute :elevation, Integer
end

irb: ad = Routine.new(:elevation => 133)
=>< Routine:0x007ff29e860e78 not initialized>

@jayceef I haven't used Rails 5 but it looks like the not initialized message comes from an inspect method that is checking if @attributes exist on the model. (see here). My guess is you need to implement an initialize method of your own and call super.

Having said that, I don't think it's a good idea to mix Virtus and ApplicationRecord/ActiveRecord. I've had luck using it with ActiveModel but it's pretty tricky.
