Hi, I am doing an eager loading in ruby on rails using below statement ------------------------ Article.find(:all, :include => [:asset, :vote], :conditions=>"assets.parent_id is null", :order=>"stat_final_ranking desc", :limit=>20) --------------------------------------- the above statement resulted in this expensive query.

I''m converting our app into restful rails. A couple of my classes (Resource and Asset) have a has_many relationship with each other - here''s the routes: map.resources :assets, :has_many=>[:resources] map.resources :resources, :has_many=>[:assets] I''m getting something weird in my view pages. When i go to /resources/4/assets it works. I go to the page

A model has 2 columns in its table asset_type_id asset_id the asset_type_id links directly to the table asset_types via a belongs_to asset_types contains a single column ''name'' method_missing in the model says when you call a method matching /^asset.*/ call the corresponding method substituting ''asset'' for the contents of asset_type.name (ie. the name in

User needs to pick a single asset from a list of assets shown via a popup window. ATM the popup view is just a simple index/list view of asset resources. Right now the user can manually enter an asset identifier after finding the desired asset in the popup. I''m interested in allowing the user to select the requested option by double clicking it. I would appreciate any suggestions on

I have two models: assets and makes. Make has many assets and an asset belongs to one make. I am calling this part of my asset controller from a search form with the parameters "search" (search term) and "field" (database field heading) which then renders a partial with the search results on it. ######################################################## if

Hi Everyone, I was going through the Rails tutorial from here: http://ruby.railstutorial.org/chapters/filling-in-the-layout#top I was getting this exception on my WebRick server: Started GET "/assets/blueprint/print.css" for 127.0.0.1 at 2011-11-28 14:43:00 +0530 Served asset /blueprint/print.css - 404 Not Found (0ms) ActionController::RoutingError (No route matches [GET]

Hello List, I''m trying to generate examples for some list-helpers I have coded which use in my projects. Basically, the Playlist class uses one anonymous module in has_many that acts as helper between acts_as_list and my desired API: class Playlist < ActiveRecord::Base # associations go here has_many :playlist_items, :order => :position, :dependent => :destroy has_many

describe Asset, " when destroyed" do fixtures :assets, :videos, :sites, :publish_settings before(:each) do @asset = assets(:test_asset) @mock_hook = mock("hook") @asset.video.stub!(:hook).and_return @mock_hook # error occurs here end it "should call the delete hook" do @mock_hook.should_receive(:update).with("test_video",

I have two classes, InstructionalObject and Assets. They both have_many of the other, implemented through a join table (so it''s like a habtm without the habtm). For the next version of our app, we''re refactoring to RESTful, and i''m having trouble with my nested resources/routes. I tried this, in routes.rb: map.resources :assets do |assets| assets.resources

e.g. class Asset < ActiveRecord::Base validates_presence_of :asset_number, :make, :model, :location, :name, :serial_number validates_numericality_of :asset_number validates_uniqueness_of :asset_number belongs_to :user belongs_to :location belongs_to :asset_type, :foreign_key => ''type_id'' end class Location < ActiveRecord::Base validates_presence_of :name

I am displaying a bunch of records from a table called "assets". Next to each record i have a checkbox. When this box is checked i want to be able to save the id of the record into another table called "flagged_assets". All I need is the ID, nothing else. Im struggling with the logic to save to another table. I know how to do it if the asset_id is already in the

Hi, I''m having a rather annoying problem which can only be explained with an example, so here we go. I have a Person class which has_many :assets. An Asset has_one :game. I would like every Person''s asset to be sorted by its game''s title, similar to this: has_many :assets, :order => ''game.title'' That doesn''t seem to work. A

In my schema, a question has_many :answers. When the validations are run on a question, and one of the answers is not valid, then i get "Answers is not valid" coming out of errors.full_messages. I don''t want this, i''m already testing the validity of the answers and this is an ugly and uninformative error message. It looks like it''s the message i would get

In 2fe70c1 (last year), rails changed from a static list of assets.paths to automatically register any path under assets/*. (This was not reflected in Rails Guides so I pushed an update to docrails.) However, in my opinion, these automatic asset paths create confusion. The result is that the first-level directories under `(app|lib|vendor)/assets` get swallowed and if I put assets into a

If I have a class, Asset, which has and belongs to many associated Asset objects, how do I do this? has_and_belongs_to_many :associated_assets, :class => "Asset", :foreign_key => ?????, :association_foreign_key => ????? Right now, my table has a :first_asset_id and a :second_asset_id, but I don''t see how the objects themselves are supposed to distinguish one from the

Hi All, I am making a DAM (seems to be the hip thing to do these days). It is for the company that I work for. We have some really weird domain rules that have prevented me from just using a simple directory structure file permission system. I have come up with a solution but I wanted to run it by you gurus to ensure that I am not recompiling the wheel here. Basically the domain rule is: A user

Consider the following: class Event belongs_to :event_object, :polymorphic => true end class Asset < ActiveRecord::Base end class EventedAsset < Asset has_one :event, :as => :event_object end EventedAsset.find(:first).event generates the following SQL: SELECT * FROM `events` WHERE (events.event_object_id = 1 AND events.event_object_type = ''Asset'') LIMIT 1

Just monkey patched Sprockets in our Rails 3.2.9 app to override the Cache-Control header for html assets that we need to tweak more often in development, but that we don''t want to use digests/fingerprinting with: # Sprockets 2.x patch if Rails.env.development? module Sprockets module Server private alias_method :sprockets_headers, :headers def headers(env,

Hi, I am working on a project that is using Paperclip to upload multiple images to an Asset model. my Post model has_many Assets.

Dear All, I am using package fPortfolio to run minimum variance portfolio optimizations in R. I already know how to set portfolioSpecs, portfolio objects and constraints. Unfortunately I am not able to set the following type of constraints. I have a timeSeries object with returns data for roughly 1.5k assets for 261 subperiods (workingdays) and want to compute the global minimum variance
