Hello I have been trying a number of security/login generators recently. My favourite so far is the Acts_as_authenticated. I like the fact that it is only billed as a starting point and doesn''t try to do everything. I would like to add security roles to it, so that some of my controller actions can only be used by an admin role. Has anybody implemented this using

Hello everybody I have a model with better_nested_set. In my "new" form, i pass the desired parent_id as a hidden field, and in the create action at the controller i save the new register and use move_to_child_of Model (params[item][parent_id]) Everything works, but at my log file it warns that i can''t mass asign the property "parent_id". What can i do to avoid the

I have a couple of resources, one nested in the other, such that my resource spec in routes.rb is: map.resources :parents, :has_many => :children This will generate a route for a new child that assumes that the parent has already been saved, something like: /parents/:parent_id/children/new But what if I want a route that handles the case where the parent resource is also new, and thus

I''m trying to create a form where a collection is created, using the example from the Rails 0.9.5 weblog posting: http://weblog.rubyonrails.com/archives/2005/01/26/rails-095-a-world-of- fixes-and-tweaks/ I''m having a bit of trouble. The controller currently looks like this: class StudentController < ApplicationController def new render_text @params.inspect

I need an ordered (sortable tree) and I just was thinking if somehting like this is possible: class Item< ActiveRecord::Base acts_as_tree :order => "position" acts_as_list :scope => ''parent_id = #{self.id}'' end For my understanding mixing of two acts_as should be p?ssible, at least in this case, right? Unfortunatly the :scope is not working, I am not

With ref to my previous post: http://www.ruby-forum.com/topic/180356 I am now able to access items from topics controller. However, now I need to add sub-item e.g.: An item itself could have many sub-items. So my items model is like: class Item < ActiveRecord::Base validates_uniqueness_of :title, :scope => [:topic_id] validates_presence_of :topic_id, :title, :owner, :position

The recent refactoring didn't work properly for new smart pools, so I've cleaned jup the parameter handling for the various pool 'create' actions.

Hi Railers, I''ve got a Categories table. I want it to act as a list within the scope of the parent_id AND the site_id. Categories table : id label site_id parent_id So, in my Category class, I have : acts_as_list :scope => ''site_id = #{site_id} AND parent_id = # {parent_id}'' The problem is that when I try to move_up a Category with a parent_id that is null,

Don't assume every disk <Item> has a <Parent> field. For floppy disks this is not the case.

I just switched from using the standard "id" column into using my own primary key and generating my own unique id for each record. But, this breaks acts_as_tree. Because my new primary key is not an integer, it breaks the SQL query as follows: StatementInvalid in PagesController#create --------------------------------------------------------------------------------------

Here''s a request string which has a value I want to pull out from the category array - parent_id. Parameters: {"category"=>{"name"=>"Condiments", "parent_id"=>"1"}, "commit"=>"Create"} How do I reference that subelement in the receiving script? I''ve tried params[:parent_id]

Hi, I''m using the latest gem version of rails under MacOS Tiger. I was trying to use acts_as_tree as described in the rails book. So I have something like: class Category < ActiveRecord::Base acts_as_tree :order => "title" end create table categories ( id int not null auto_increment, title

I am working on an Rails application that uses a pretty complex category structure through out the site. I have defined a table to house all the info and a FK to reference parents within the table CREATE TABLE categories ( id int(11) NOT NULL auto_increment, name varchar(50) NOT NULL, parent_id int(11) default NULL, constraint fk_category_id foreign key (category_id) references

I am trying to create a record with association. Within the create method, I would also like to pre-populate dependent (has_many) records from a template in the database. The child records are <u>mysteriously rolled back </u> if I insert them in a loop. If I try to insert a single child record, it works.I have read the books and tried to google my way out of this but am at a dead

Hello, I am just starting off with Rails, so I apologize in advance if there is a terribly obvious answer to my problem. I''ve done some searching and found similar problems to my own, but nothing which yielded a solution. I have a handful of models that I am unit testing. The tests for each unit run successfully, but when I do a rake test, many of the tests fail. The assertions that

Guys, I''m having a problem getting acts_as_tree working. It seems from the Agile book (p. 255) that acts_as_tree only supports one-to-one record relations, whereas I need many-to-many support. In other words, looking at the picture at the top of page 256 where where only 1 id is linked to 1 parent_id, I need multiple id''s linked to multiple parent_id''s - for
