Rake aborted! stack level too deep

Hello,

I have trouble with migration files. Every time when I try create a
record by migration file I have error: "Rake aborted! stack level too
deep"
(look bellow to see content of my migration file and my rails
environment)

This error is very tricky, I do hot sure but sounds like this error
happen
when ruby could not find a method

I found that problem at the two places. One is:
''paginating find'' plugin
http://cardboardrocket.com/pages/paginating_find

and second is:
''userstamp'' plugin
http://www.delynnberry.com/articles/category/userstamp/

There is code at the paginating find:

  def self.included(base)
    base.extend(ClassMethods)
      base.class_eval do
        class << self
          alias_method_chain :find, :pagination
        end
      end
    end
  .....
    def find_with_pagination(*args)
      options = extract_options_from_args!(args)
      .....
      .....
      .....
        # The :page option was not specified, so invoke the
        # usual AR::Base#find method
        find_without_pagination(*(args << options))
      end
    end

I can see at the log that error happen after when was executed
  -> body of find_with_pagination
    -> call find_without_pagination(*(args << options))
      -> body of find_with_pagination
        -> options = extract_options_from_args!(args)

As I can understand the ''find_without_pagination'' method call
executes ''find_with_pagination'' instead.

Sounds like alias_method_chain :find, :pagination does not work with
rake
(that is strange, should not be like that).

I fixed the trouble but solution was not great. I have replaced:
  alias_method_chain :find, :pagination

By:
  alias_method :pagination_find, :find_with_pagination
  alias_method :find_without_pagination, :find

And all places where I need a pagination find I use ''pagination_find
method''
and use just ''find'' at other cases

Other place which makes error is a userstamp plugin
And here the same trouble

  alias_method :create_without_user, :create
  alias_method :create, :create_with_user
  alias_method :update_without_user, :update
  alias_method :update, :update_with_user

  def create_with_user
    if record_userstamps and user_model.current_user != nil
      write_attribute(:created_by, user_model.current_user.id.to_i) if
respond_to?(:created_by) and self.created_by.nil?
      write_attribute(:updated_by, user_model.current_user.id.to_i) if
respond_to?(:updated_by)
    end
    create_without_user
  end

  class Base
    @@user_model_name = :users
    cattr_accessor :user_model_name

    @@record_userstamps = true
    cattr_accessor :record_userstamps

    def self.relates_to_user_in(model)
      self.user_model_name = model
    end

    def user_model
      Object.const_get(self.user_model_name.to_s.singularize.humanize)
    end
  end

When user_model is
Object.const_get(self.user_model_name.to_s.singularize.humanize)
It has error at the singularize (look at reports bellow)

When I changed code of user_model to just return User the error at the
method create_with_user when it try call create_without_user

Sounds like it can''t find create_without_user method. At result there
is same trouble with alias_method and migration as abowe

And last point. The troubles only with rake and no troubles
when application works as web server.

Re: Rake aborted! stack level too deep

Hmmm, my message was not clear... I want give few important comments
>Other place which makes error is a userstamp plugin
>And here the same trouble
Next going the code of userstamp plugin
>  alias_method :create_without_user, :create
>  alias_method :create, :create_with_user
>  alias_method :update_without_user, :update
>  alias_method :update, :update_with_user
Other thing
>Error message when:
>  def user_model
>    User
>  end
I mean that the user stamp has the method ''user_model'' which
is actualy
different and make error also (what is also I need to understand), but I 
replace that code to this simple variant:

Also when error log has next lines at the top of log:

rake aborted! stack level too deep
D:/AppFrameWork/RAdmin/config/../vendor/plugins/userstamp/lib/userstamp.rb:32:in
`create_without_user''
D:/AppFrameWork/RAdmin/config/../vendor/plugins/userstamp/lib/userstamp.rb:36:in

The source code had linenumbers

31    def create_with_user
32      if record_userstamps and user_model.current_user != nil
33        write_attribute(:created_by, user_model.current_user.id.to_i) 
if respond_to?(:created_by) and self.created_by.nil?
34        write_attribute(:updated_by, user_model.current_user.id.to_i) 
if respond_to?(:updated_by)
35      end
36      create_without_user
37    end

Function call order is:
  -> create_with_user
    -> create_without_user
      -> create_with_user

So stack overflowed cause the function calls byself.

As result, I have recoded plug-ins source with inheritance. And I will 
avoid of using class extending with ''alias_method''
