I have two sortable lists that you can drag and drop to and from. Each object in the lists have a position field in the object''s table. I want to be able to update the position in the database automagically once a user has sorted the list. I can drag and drop just fine but I am not able to store the new positions in the database. I am trying to use Ajax.request in the onUpdate callback

Greetings, R-help! On 2 Fedora Core 2 Linux systems, i've completely erased the previous R and all packages and then installed R-2.0 and installed fresh packages. In using Rcmdr, I see some trouble and I wonder if other people see this and if it is due to the tcl/tk, or R, or Rcmdr. (If readers have not yet tried Rcmdr, I recommend it not just because of the GUI it provides, but also

Hi, I am using Scalar Evolution to extract access expressions (for load and store instructions) in terms of the loop induction variables. I observe that the Scalar Evolution analysis is returning more expressions than I expect - including ones that are not defined in terms of the loop induction variable. For instance in the following code: for(unsigned long int bid = 0; bid < no_of_queries;

In my User form I have standard field to get user record attributes (first_name, last_name and email) I also have a select drop_down to choose a role from an array first_name, last_name and email are user record attributes, but I defined the role name as a virtual attribute validates_presence_of :email, :last_name attr_accessor :role_name validates_presence_of :role_name, :if =>

I''ve got a publications table that contains an author_id foreign key and a pubrole_id foreign key. What I want to do is query the DB using AR so that I can get a list of all publications that belong_to a particular author, and group the results by the pubrole.role_name (Author, Joint Author, Editor, etc.) so that the results look something like: Author book1 info book2 info etc.

I have a model layer containing Movie, Person, Role, and RoleType, making it possible to express facts such as "Clint Easterbunny is director of the movie Gran Milano". The relevant model and associations look like this class Movie < ActiveRecord::Base has_many :roles, :include => :role_type, :dependent => :destroy has_many :participants, :through => :roles, :source

Could you be more specific about what is not working? -- Are your association methods between Role and User being set up correctly? (If not, make sure your statement is "has_and_belongs_to_many", and not "hasandbelongstomany".) -- Are you storing the data for role_name in the index? If so, can you see it there? I''m not familiar with the find_with_ferret

Hi Hashim, Scalar evolution determines evolution of scalar in terms of expression chain driving it. Try dumping the detailed log using opt -analyze -scalar-evolution <.ll> -S , and look for LoopDispositions corresponding to different expression which shows variance characteristics of a particular expression w.r.t loop i.e. [computable/variant/invariant].

I''ve been bringing up a good basica framework for applications at work. To give decent security I''ve been implementing the Rails Recipie for Authorization of function calls modeled on the book''s implementation. (Changes for our environment were added..but are minor.) Since I initially let Rails create the join table between two data tables with a HABTM relationship....I

I want to create table called roles and then populate it with some new records...This doesn''t work. Is there something I''m missing? Craig class AddRightsAndRolesTables < ActiveRecord::Migration def self.up create_table :roles do |t| t.column "name", :string end Role.reset_column_information Role.new :name => "Users Admin"

I have multiple roles in my application. Now I want to block a method for all users except the administrator and a manager. When I do this: before_filter (:check_administrator_role), :only => [:administration] before_filter (:check_taskmanager_role), :only => [:administration] The user must have both roles. How can I change that to an "OR" combination? -- Posted via

Hi all, In the application i develop, a sophisticated login system is required. Being a newbie in Ruby, i''m not comfortable with the select tag in the form tag. My requirement: 2 tables - User(LoginName, Password, RoleId...) and Role(RoleId, RoleName...) View - RoleNames to be loaded in the drop down box and On submit, RoleId to be passed to controller for authentication. My Code

Hi, I have defined this route as the first one: map.connect '':controller_prefixx/:controller/:action'', :controller_prefixx => ''rails_right'' (for the test, I put a second x at the end to be sure I don''t collide from the :controller_prefix used in rails). In my view, I have this: <% @rights.each do |right| %> <tr>

Hello all, I''m currently designing a web app in Rails that lets me keep a directory of free/opensource computer games. Each game has attributes like name, website, review, etc., but each game can also be associated with a set of genres and gameplay elements. The main three tables I''m working with are "games", "genres", "elements",

I have a problem declaring a relationship through a join_table ; the SQL generated by ActiveRecord is correct, but there are two columns called ''id'', and the final object gets the ''wrong'' column ... Here''s a more detailed description of the data, code, and problem :- There''s a People table, with id, name, and a few things. Also a

However my application also needs a

Hello list, I think I''ve found a bug in the way Rails is talking to my Postgres DB when recording HABTM data. My join_table looks like this: id serial primary key, tablea_id integer references tablea(id), tableb_id integer references tableb(id), other_attributes... When Rails writes to join_table, I''d expect it to do something like: INSERT INTO join_table (tablea_id,

Hey, Just wondering if anyone else has noticed this. I''m using thin+puppetmasterd+nginx. If i add a host, sign it''s key, run puppetd successfully on it all is good, as expected. If i then revoke/clean the key on the master server, leave the box running, startup another host set the hostname to be the same as the old, generate new keys/have them signed. The original box is still

Hi Chris, Yesterday you kindly submitted an answer to my question on modelling many to many relationships. I''ve briefly tried the proposed solution but so far with no luck. Before I get too involved - I''d like to know if mapping three way :join_tables is "legal" in a Rails sense. I only ask since you put (untested) in your mail and I can''t find any docs on
