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
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.
My migration file
class CreateDefUsers < ActiveRecord::Migration
def self.up
User.create( { :id => 1,
:login => 'root', :password => "root",
:password_confirmation=>"root",
:email=>"[email protected]", :role =>:root, :company_id=>1 } )
end
def self.down
end
end
Error message when:
def user_model
User
end
