Will_paginate barfs in project with no ActiveRecord
Reported by ronin-20496 (at lighthouseapp) | May 16th, 2008 @ 05:21 PM
If you try to use will_paginate in a Rails project that does not use ActiveRecord, for example:
Rails::Initializer.run do |config|
#
- Project is not currently using a database, so...
config.frameworks -= [ :active_record ]
end
your the server will die on startup with this error:

I don't really have a patch, because I couldn't figure out how to write a test for it. I worked around the problem by commenting out "enable_activerecord"
module WillPaginate
class << self
- shortcut for enable_actionpack; enable_activerecord
def enable
enable_actionpack
- enable_activerecord
end

Use the latest gem. You can see by this code that it doesn't call WillPaginate.enable unless both ActiveRecord and ActionController are present.
If you don't use ActiveRecord, just call
WillPaginate::enable_actionpackyourself after requiring the library from the gem.
