acts_as_list_mongoid's Issues

undefined method 'set_allowed?'

First I want to thanks for porting this gem. Whenever I try to us this on a document in my app, I keep receiving the error undefined method 'set_allowed?'. I've forked your repo and run the tests and am getting the same error. I've tried to trace the stack, reviewing the code in both of your other gems, mongoid_embedded_helper and mongoid_adjust, but I can't seem to figure out where the 'set_allowed?' method is being called. I'd be happy to try and create a patch if you could point me in the right direction. My app is using rails 3.1.0.rc4 with mongoid 2.0.2. Thanks!

move(:bottom) results in 'wrong number of arguments' - mongoid 3.1.2

ruby-1.9.3-p385
mongoid-3.1.2
mongodb version v2.4.0

embedded documents

move(:top) works

# document 'doc' has many embedded documents 'eds'
e = doc.eds.last
e.move(:top)
d.eds.map(&:position)
   => [2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 1] 
doc.reload
doc.eds.map(&:position)
   => [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19] 

move(:bottom) crashes

doc.eds.map(&:position)
   => [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19] 
e = doc.eds.first
e.move(:bottom)
# fails. see stacktrace below.
doc.eds.map(&:position)
   => [1, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18]

Define columns automatically

It would be great if all that was needed was

include Mongoid::ActsAsList

Then it'd automatically create a position field, and initialize the code without having to call field yourself or calling acts_as_list.

Is this possible?
