Position field #316

A few months ago, I asked for help to use a field 'position' with Typus. Today I have the problem again. I have new actions in typus "Top / Up / Down / Bottom". Unfortunately, I have a beautiful "The action 'position' could not be found for Admin::ProjectsController" message when I try to click it. I have try to add acts_as_list gem but I have still my error.

Thank you

On the required controller you need to include the ActsAsList module:

include Typus::Controller::ActsAstList

This indeed works, however small typo. Should be:

include Typus::Controller::ActsAsList

If I include the Typus::Controller::ActsAsList I get following error on the edit page of my model:
undefined methodmodel_name' for NilClass:Class`
Extracted source (around line 3):

3: <%= form_for @item, :url => options, :html => { :class => "resource", :multipart => true } do |form| %>
5:   <%= render "helpers/admin/resources/errors" %>

If I comment out the include, everthing works in the edit action.

Anyone an idea how to fix this?

Does your model includes acts_as_list?

Yes it does. And I already included the gem acts_as_list itself in the Gemfile.

I think that this problem is a little bug in https://github.com/fesplugas/typus/blob/master/lib/typus/controller/acts_as_list.rb line 6 and 7.

Can be solved adding:

  before_filter :get_object, :only => Whitelist + [:show, :position]
  before_filter :check_resource_ownership, :only => Whitelist + [:position]


  include Typus::Controller::ActsAsList

Ok if I do the tings @spejman said I get following error:
undefined method "move_lower"

@mattherick you have to add acts_as_list in your model in order to have move_* methods in the object.

Ah I already did that, but in the wrong model :-). Thanks, now it works!

This issue is still happening. Confirmed with typus v3.1.10 and acts_as_list v0.1.6. Trick from @spejman works for me.
