similar to: Bypassing automatic STI generation

Hello all This is my first post so excuse the basic question. (and any repeats I just got an email saying this post was too big so I have re-submitted a smaller version) I was following the thread on http://lists.rubyonrails.org/pipermail/rails/2006-May/038988.html regarding the STI on HABTM for RoR. I have a very similar problem and was hoping for some help. I have the

Hello, is it possible to setup a model/table schema like this: Groupable --> Membership <-- Group ^ ^ | | User UserGroup I tried the following but failed: Groupable (table with ''type'' column) has_many :memberships, :as => :groupable has_many :groups, :through => :memberships

Hello, I have been following the STI example in AWDWR and have a question about presenting the output. I want to output a list of Person objects that are grouped by their type. I have an array of all the Person objects and I would like the output to be as follows. Employee x3 <ul> <li>Employee 1</li> <li>Employee 2</li> <li>Employee 3</li> </ul>

Hello, I have set up that uses single table inheritance. I have a number of model subclasses following the example in AWDWR that uses Manager < Employee < Person. First question. Do I need to create controller classes for each? I don''t think I do because a single controller should be able to shunt the data between the models and the views. Second question. Say I have a view

I have just some vague and thus probably wrong ideas about when to use model() in controllers, and by now I err on being redundant. I don''t post them here to avoid leaving anything that may be false in the archives. Can anyone explain exactly in which cases one should use model()? -- fxn

Hi there, I''m currently building a membership application and I want to be able to select, not just all the memberships, but the most current membership from the database on a per user basis. I have linked the tables as shown:- class Membership < ActiveRecord::Base belongs_to :payment belongs_to :person end class Person < ActiveRecord::Base has_many :memberships

the below... class User < ActiveRecord::Base has_and_belongs_to_many :teams class Team < ActiveRecord::Base has_and_belongs_to_many :users has_one :captain, :class_name => ''User'' produces the error... Mysql::Error: Unknown column ''users.team_id'' in ''where clause'': SELECT * FROM users WHERE (users.team_id = 1) LIMIT 1 i

HI, i use models User and Groups connected with many to many association, so i have users table, groups and groups_users. lets say i create one user and one group. next i add a group to user. so now my table groups_users has one entry i.e. group_id | user_id _________|________ 1 | 1 ok, when i delete both my group and user, above entry is not deleted, thus leaving alone without

How should you map resources that are join models like Memberships? Lets say have you have Members and Groups that are joined through Memberships. map.resources :members do |members| members.resources :groups do |groups| groups.resources :memberships end end This doesn''t seem right. It would be nice to access all members, groups, and memberships at /members,

All, I wonder if someone can give me an idea what the file "netsamlogon_cache.tdb" contains... as I have noticed that I can be added to a group, and access will not appear on the Unix side for a good deal of time... but if I stop Winbind, remove the file "netsamlogon_cache.tdb", and re-start everything, it will then work. Can anyone tell me what the purpose of this file is,

Hi! Recently I've been working with the rest of the X.Org board to try to get X.org access to VESA memberships so that contributors that don't have an employer who is able/willing to join VESA can potentially get access to the various benefits of a VESA membership, such as access to DisplayPort specifications. Since I need to gather a list of interested X.org members, I'd like to know

I have a problem with the :include option in find for my has_one :through association. I have Users, Profiles and Customers, all connected to each other with a has_one :through => :membership association like this: class Profile < ActiveRecord::Base #could also be user or customer has_one :membership # i saw an acrticle of Ryan about has_one :through, there this would be has_many, is

Hi, I know that the AWDWR says to believe in magic and to not spend Xmas with people asking this question, but really how does it work under the hood? I was looking at the source code of crummy, and it seems that instance_variable_set and instance_variable_get may be part of the answer. Is there some resource on that or do I have to dive into Rails code? -- Posted via

Dear All, I am attempting to use the FANNY fuzzy clustering function in R (Kaufman & Rousseeuw, 1990), found in the "cluster" package. I have run into a variety of difficulties; the two most crucial difficulties are enumerated below. 1. Where is the 'm' parameter in FANNY?

Folks; using samba+winbindd+pam+nsswitch to make several Linux servers authenticate against an AD domain, I do have my setup mostly working now: - AD users are able to ssh into the machine. - wbinfo -g / -u does list all domain users. - getent group / getent passwd does list Unix and AD users. However, after changing some users group memberships in AD, I didn't manage to propagate this
