I have a strange issue setting data inside an active record..
When I attempt to set the data inside a method, it doesn’t seem to affect anything.

Here’s my class

class Option < ActiveRecord::Base
  serialize :returns_policy_refunds, Array
  def reloadRefundOptions!
    @returns_policy_refunds = WebSite.get_refund_options #options array
  end
end

Simple as’ class eh?

To test serialization I’m just spitting out the data on a screen.. 

-@options.each do |option|
  - option.returns_policy_refunds = ["wtf"] #just to reset things

  <b>BLOCK 1</b>
  = option.reloadRefundOptions!
  = option.returns_policy_refunds
  <br>
  <b>BLOCK 2</b>
  = option.returns_policy_refunds = WebSite.get_refund_options
  = option.returns_policy_refunds

Now.. I’d expect to see the same in BLOCK1 as in BLOCK2..
The method sets the return policy..
What I actually see in the first option.returns_policy_refunds is [“wtf”]

What am I missing? I must be doing something wrong, but I have no idea what.
Any thoughts?

    Leave out the @ in your attribute assignment:

    class Option < ActiveRecord::Base
  serialize :returns_policy_refunds, Array
  def reloadRefundOptions!
    self.returns_policy_refunds = WebSite.get_refund_options #options array
  end
end

    Haven’t tried it yet but I would say that option.returns_policy_refunds gets the data from the attributes hash defined by ActiveRecord. If you assign a class variable using @ it’s just defined there and may only be accessed with an attribute reader or a direct send.
