Facebooker talk - Sep 2008 - ArgumentError: Unknown key(s): dependant

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
`assert_valid_keys''
        from
/usr/lib/ruby/gems/1.8/gems/activerecord-2.0.2/lib/active_record/associations.rb:1187:in
`create_has_one_reflection''
        from
/usr/lib/ruby/gems/1.8/gems/activerecord-2.0.2/lib/active_record/associations.rb:727:in
`has_one''
        from /home/marc/rails_projects/project/app/models/album.rb:2
        from
/usr/lib/ruby/gems/1.8/gems/activesupport-2.0.2/lib/active_support/dependencies.rb:203:in
`load_without_new_constant_marking''
        from
/usr/lib/ruby/gems/1.8/gems/activesupport-2.0.2/lib/active_support/dependencies.rb:203:in
`load_file''
        from
/usr/lib/ruby/gems/1.8/gems/activesupport-2.0.2/lib/active_support/dependencies.rb:342:in
`new_constants_in''
        from
/usr/lib/ruby/gems/1.8/gems/activesupport-2.0.2/lib/active_support/dependencies.rb:202:in
`load_file''
        from
/usr/lib/ruby/gems/1.8/gems/activesupport-2.0.2/lib/active_support/dependencies.rb:94:in
`require_or_load''
        from
/usr/lib/ruby/gems/1.8/gems/activesupport-2.0.2/lib/active_support/dependencies.rb:248:in
`load_missing_constant''
        from
/usr/lib/ruby/gems/1.8/gems/activesupport-2.0.2/lib/active_support/dependencies.rb:453:in
`const_missing''
        from
/usr/lib/ruby/gems/1.8/gems/activesupport-2.0.2/lib/active_support/dependencies.rb:465:in
`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.

Marco, check out the error message:

ArgumentError: Unknown key(s): *****dependant*****

It looks like this argument is spelled wrong in your model. I believe  
it is dependent with all Es.
