Exception in Rails 2.3.2 when using :group

Reported by Paco Benavent | April 17th, 2009 @ 12:58 PM

Using will_paginate-2.3.8 with Rails 2.3.2 raises an exception when using :group


 User.paginate :all, :finder => 'count', :group => 'country', :page => 1
TypeError: can't convert ActiveSupport::OrderedHash into Array
from /usr/lib/ruby/gems/1.8/gems/mislav-will_paginate-2.3.8/lib/will_paginate/collection.rb:135:in `replace'
from /usr/lib/ruby/gems/1.8/gems/mislav-will_paginate-2.3.8/lib/will_paginate/collection.rb:135:in `replace'

from /usr/lib/ruby/gems/1.8/gems/mislav-will_paginate-2.3.8/lib/will_paginate/finder.rb:76:in `paginate'
from (irb):5

This is because in Rails 2.3.2, OrderedHash changed from being a subclass of Array to a subclass of Hash.

    • State changed from “new” to “open”

    Good catch. Will try to fix soon

    Thank you for your response!

    I made a quick fix that worked for me, changing line 82 in finder.rb


        pager.replace(send(finder, *args) { |*a| yield(*a) if block_given? })


        pager.replace(send(finder, *args) { |*a| yield(*a) if block_given? }.to_a)

    Hope it'll help.
