[Facebooker-talk] ArgumentError: Unknown key(s): dependant

[Marco Durden]

Hello,

I came across an association error today with facebooker.

class Cover < ActiveRecord::Base
  belongs_to :album
end

class Album < ActiveRecord::Base
  has_one :cover, :dependent => :destroy
end

At the console:

>> Album.find :first
ArgumentError: Unknown key(s): dependant
        from
/home/marc/rails_projects/project/vendor/plugins/facebooker/lib/facebooker/rails/helpers.rb:589:in

        from

`const_missing'
        from (irb):1



So what I did, I went to line:586 of
vendor/plugins/facebooker/lib/facebooker/rails/helpers.rb:589:in
`assert_valid_keys'

585  # We can allow css attributes.
586  FB_ALWAYS_VALID_OPTION_KEYS = [:class, :style]

  and changed it to :

586  FB_ALWAYS_VALID_OPTION_KEYS = [:class, :style, :dependant]
587  def assert_valid_keys(*valid_keys)
588   unknown_keys = keys - [valid_keys +
FB_ALWAYS_VALID_OPTION_KEYS].flatten
589    raise(ArgumentError, "Unknown key(s): #{unknown_keys.join(", ")}")
unless unknown_keys.empty?
590  end


And now I no longer get the error.  If anyone has come across this error, or
if they know if this change will cause problems down the road, please let me
know.
