Hey guys, I just came across this oddity, not sure what to make of it yet, but I think it might be incorrect behavior. When doing a @inst.find(:all, :include => ["hometeam", "awayteam"] ...) hometeam and awayteam are two references from a belongs_to that is of the same model and of the same table. I will get a pgerror stating that "matches", which is

When I do this: term = Term.find(1, :include => :definition) term.definition.term Two SQL queries are fired, why? -- Posted via http://www.ruby-forum.com/.

I have an ActiveRecord class that has several has_many,belongs_to, habtm, and the new has_many => :through relationships. Whenever I try a find(:all, :conditions => "some conds", :include [:relationship]) it works fine, but if I have find(:all, :conditions => "some conds", :include [:relationship, :other_relation]) it gets a sql error such as Mysql::Error: You

For example, in the following block: page.select(''.foo'').each do |element| ... end How would I access, just for example, the id attribute of each element in the collection? I''ve randomly tried element.id and element.attributes[''id''], but neither of those has worked. I''ve also been unsuccessful in finding any documentation on this, but it

I have a page that renders a series of about 20 checkboxes on the left hand side with content on the right. These checkboxes are created from a DB and that part is all working well. What I want to do is have a user click on a checkbox [genres] and have the content on the right be filtered based on the checkbox ticked. If a user clicks on more than one checkbox than only those stories

Hi, I currently have a MySQL database containing all Puppet storeconfigs. My intention is to migrate to PuppetDB on a PostgreSQL server, so the first step is to use the ''storeconfigs'' face to export all the DB to a file PuppetDB can later consume. But the ''puppet storeconfigs export'' command always ends up being killed, I suspect due to some sort of OOM

Hello. About your idea, I think that it is important for a radio to "check" multiple styles. I'm planning to cast a couple or 3 of stations that are _not_ monographic and will be "sports" from x to y hours, "pop" from y to z hours, "talk" from z to p hours and so on. That is because people that are listening the same genre for hours want to change. Why

Hi, I m very new to Ruby. I bought a book "Ruby on Rails" and I think I understand some concepts. My question is : Is there a way to not use "Cookies" or "Sessions Variables" to keep some information about the user. I ask this question because I would like to prevent some cases where the user browser won''t accept cookies. I m from Asp 3.0, and I

hello there, i have a model that uses acts_as_tree: >class GbEntry < ActiveRecord::Base > acts_as_tree :order => ''created_at DESC'' >end and i want it to paginate, including all children to avoid unnecessary db queries: > @gb_entry_pages, @gb_entries = > paginate :gb_entries, :per_page => 15, :order => ''created_at DESC'',

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",

Hello I have 2 models. link.rb has_many :categories, :as => :categorized validates_presence_of :name, :url, :created_at, :category category.rb belongs_to :categorized, :polymorphic => true validates_presence_of :name Everything seems to work. I select my category from a select tag. The problem is i don''t know how to validate if category is for example empty (nothing in a

I''ve just been bodyslammed by a problem with has_and_belongs_to_many - as far as I can tell, if it doesn''t appear at the top of other relationship definitions it doesn''t seem to work right. For example: class Artist < ActiveRecord::Base has_and_belongs_to_many :genres has_many :albums has_many :videos has_many :cds has_many :collections end ..works fine

So I've been doing some research and thinking here and there about what a _good_ directory service for icecast would be like. I'd appreciate some feedback and some discussion on this topic, before I start putting a lot of effort into developing it. First off, I think getting rid of # of listeners is a must. It just creates a self-fulfilling prophecy and encourages cheating. I think the

Hey I''m having problems understanding the select helper. Here is my code: _____________________ DB table: genres id name descripition ___________________ In the controller: def index() @genres = Genre.find_all.map {|u|[u.name, u.id]} @id = params[''genre''] end ____________________ In the view: <% @genre = Genre.new @genre.id = @id %>

This seemed to be the best place to let you guys know.... Magnatune.com's entire catalog is now downloadable in Opus format, with full metadata (small and large cover art) at 128k stereo. A few comments: 1) I'm really impressed by your metadata implementation. It's very cleanly done, and the multiple artwork idea is fantastic. One suggestion: I couldn't find an example in the

Hello, I'm thinking of ordering an OpenVox A400P01 (A400P + 1 PORT FXO Bundle) for use in a old IBM 8364 thin client: http://www.openvox.com.cn/products_detail.php?genre_id=9&id=28 http://silicon-verl.de/home/flo/software/netstation-8364/ Has someone already used this hardware with Asterisk, especially on a small piece of hardware like this, and could offer some feedback? Thank you.
