Possible Rails 2.1.0 issue using the Object's send method

Rails
1

Code like the following worked fine under Rails 2.0.2 but now throws an
exception under Rails 2.1.0. Has anyone else had this issue?

class BugTest < ActiveRecord::Base
def set_name(value)
send(“name=”, value)
end
end

Here’s the exception…

NoMethodError: You have a nil object when you didn’t expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.include?
/vendor/rails/activerecord/lib/active_record/dirty.rb:126:in
`write_attribute’

I came across this upgrading a site to Rails 2.1. In my case it was
attribute change tracking stuff in Rails not playing nicely with the
acts_as_versioned plugin which does something similar. The latest
version of the plugin sort this, grab it with something like “script/
plugin install git://github.com/technoweenie/acts_as_versioned.git”.

Do you know how this problem was solved or shall I dive into the
acts_as_versioned code?

I think acts_as_versioned was extending ActiveRecord with its own
changed_attributes collection. I was hoping you’d be using the plugin,
but if not then yeah, I guess you could jump in the code.
