similar to: User.already_friend_of(friend)?

In my last post I was asking how I could check for the existance of a record before inserting a new one and this was the helper method that I was using to do this: def already_friend_of?(friend) begin self.friends.find(friend.id) true rescue false end end I was told that this is not very efficient, as it hits the db every time I call it. I completely agree and would like to

In edge rails, serialized attributes are saved every time no matter they are changed or not: def update_with_dirty if partial_updates? # Serialized attributes should always be written in case they''ve been # changed in place. update_without_dirty(changed | (attributes.keys & self.class.serialized_attributes.keys)) else

i keep getting this AssociationTypeMismatch error. i think this could be a bug related to ruby/rails when using mixins. heres a short version of my code: # user.rb require ''friend_invitation'' require ''friendship'' class User < ActiveRecord::Base include FriendInvitationUser, FriendshipUser ... end # friendship.rb ... module FriendshipUser def

I''ve been following some tutorials on how to get switchtower working on dreamhost. I got the setup to work just fine, but the rake deploy doesn''t work. I get the following error. any ideas? ---------------------------------------------- > rake deploy (in /home/.interim/i8ramin/work/yaram.com) loading configuration

Here''s a seemingly simple ActiveRecord use case. I have Projects and Users. Each project has a single team leader as well as a review team that consists of several users. I would like to use the same User model for authentication and just reference these users in my Project model. I tried this but got an "unknown column" error (for User.project_id) class Project has_one

Whenever I get any errors on my application, I don''t get the regular rails error page with all the debugging information. What could''ve cause this? This is from the logs: ActionView::ActionViewError (No rhtml, rxml, rjs or delegate template found for /usr/lib/ruby/gems/1.8/gems/actionpack-1.11.2/lib/action_controller/templates/rescues/template_error.rhtml):

I am trying to create a messaging system for my users but I''m having a hard time designing my db. This is what i have in mind, but I am not sure if its the best approach. user has_one inbox user has_one outbox inbox has_many messages outbox has_many messages inbox table user_id outbox table user_id messages table box_id (refers to either inbox or outbox - how?) from_id to_id

Is there a standard practice for providing a UI into HBTM relationships? I have a model User, and a model Training, and I need to manage both relationships -- show me all the people that have training X, but also show me all trainings user U has. And, of course, "Lookup this user and then add/remove trainings for this person" or "Lookup this training and add/remove

Hallo, I am having a very strange Problem with STI in my application. setup: - two tables one called "wikis" on called "categories" with a hbtm relationship. - the wikis table is the sti one with a model PageWiki being extended from Wiki (and the correspondig type column) Following happens: - server restart - get :wikis, :show_pages - in show_pages the first line says

I wasn''t sure where to email this request, so I am hoping the author of file_column actually sees this. I was wondering if there were any plans to allow some configurability in the file_column plugin. By configurability I mean allowing the developer to define which table column is used as the unique identifier when creating image folders. Right now it seems like it uses the ID of the

Hi, I have a self-referential has_many :through relationship setup to track relationships between users. Basically relationships are modeled as a join table with an extra column ''relation''. create table relationships ( user_id integer unsigned not null, friend_id integer unsigned not null, relation char(1) not null, ) --- relations --- f = friend r = request to

I have more or less the same problem. I''m trying to build a system where users can enter their friends. But the solutions seems not to work for me. I used same sql: CREATE TABLE `friends` ( `user_id` int(11) NOT NULL default ''0'', `friend_id` int(11) NOT NULL default ''0'', KEY `user_id` (`user_id`), KEY `friend_id` (`friend_id`),

I''m curious what would be the best way to represent people and whether the person has someone marked as their friend. Here are my thoughts so far: People table - id - name Relationships table - person_id - friend_id Now my problem is I don''t know how to set up these associations (if this is even correct). Friend_id would be an id to someone else from the people table.

This isn''t Rails or Ruby related, but I just need some advice and thought I''d ask the bright individuals here. I want to start my own blog but I''m not sure where to begin. I don''t want to get a blogger account because I want to have my own domain. Blogger also doesn''t have many features. My hosting service is 1AND1 so it supports php, cgi and mysql.

Hey everyone, I''m working on allow users to follow other users in my app so they can receive updates to what all their friends are doing (like Facebook/ Twitter). I''m wondering on how the relationship would be for the model. Sounds like a HABTM type of association, but how would I go about doing it for only one model? Thanks, Tony

Hey guys, im trying to get my friends to come up at the top of the act as ferret search. I would query the whole result set first, then move my friends to the top, but the thing is, Im paginating my results and use the offset and limit parameters in the multi_search() function. Anyone know how to do this? Thanks in advance... -- Posted via http://www.ruby-forum.com/.

So I''m one of those nasty people building a self-referential habtm-like Association using the funky new :through stuff. This is about users having friends, so here''s my user.rb: class User < ActiveRecord::Base has_many :friendships, :foreign_key => ''user_id'' has_many :friends, :through => :friendships, :source => :friend end And here''s

Hi! here a little patch for darknet functionality, i hope it does what its intended for sufficiently ... but it seems to work :). what should it do? imagine your friend-network. A trusts B and C. B trusts D and E, D trust F, C trusts G. All trust relationships are mutal A <---> C <---> G ^ \ \-----> B <---> D <---> F ^ \ \---> E

Hey, sorry for the off topic email, but I appreciate any feedback you guys can give me. I just put together a new box and installed Ubuntu linux on it. I''m coming from a totally windows environment, so I''m having some trouble getting my head around the linux file system and where things "should" go. I am trying to create a nice development environment for myself
