• Rails 2.3.2: Accessing Model Specific Data in Another Model

  - by Gimli

  I'm using Rails 2.3.2 and using Paperclip to upload photos. I'm also using a slightly customized subdomain_accounts.rb to set some account-specific variables. My question is this: How can I set the bucket used in Paperclip to be dependent on the current account? Since this looks to be a model attribute set up early on, how can I override it later? Thanks.

• Why are all response bodies after the first blank in Cucumber?

  - by James A. Rosen

  I'm using Cucumber (0.6.3), Cucumber-Rails (0.3.0), Webrat (0.7.0), and Rails (2.3.5) for some tests. The following scenario passes just fine: Scenario: load one page Given I am on the home page Then I should see "Welcome" The following, however, fails: Scenario: load two pages Given I am on the FAQ pag When I go to the home page Then I should see "Welcome" The problem is that the second @response.body is blank. I added a Rack middleware to get a little more information: class LogEachRequest def initialize(app); @app = app; @count = 0; end def call(env) puts "Processing request # #{@count += 1)" @app.call(env) end end It shows me only one request processed. That is, it only ever prints out Processing request # 1

• Problem with Active Record

  - by kshchepelin

  Hello everyone. Lets assume we have a User model. And user can plan some activities. The number of types of activities is about 50. All activities have common properties, such as start_time, end_time, user_id, etc. But each of them has some unique properties. Now we have each activity living in its own table in DB. And thats why we have such terrible sql queries like SELECT * FROM `first_activities_table` WHERE (`first_activity`.`id` IN (17,18)) SELECT * FROM `second_activities_table` WHERE (`second_activity`.`id` = 17) ..... SELECT * FROM `n_activities_table` WHERE (`n_activity`.`id` = 44) About 50 queries. That's terrible. There are different ways to solve this. Choose the activity type with the biggest number of properties, create the table 'Activities' and have STI model. But this way we must name our columns in uncomfortable way and often the record in that table would have some NULL fields. Also STI model, but having columns, common for all of activity types and some blob column with serialized properties. But we have to do some search on activities - there can be a problem. And serialization is quite slow. Please help me dealing with this. Maybe my problem has quite different solution that will fit my needs. Thanks for help.

• Using Loops for prompts with If/Else/Esif

  - by Dante

  I started with: puts "Hello there, and what's your favorite number?" favnum = gets.to_i puts "Your favorite number is #{favnum}?" " A better favorite number is #{favnum + 1}!" puts "Now, what's your favorite number greater than 10?" favnumOverTen = gets.to_i if favnumOverTen < 10 puts "Hey! I said GREATER than 10! Try again buddy." else puts "Your favorite number great than 10 is #{favnumOverTen}?" puts "A bigger and better number over 10 is #{favnumOverTen * 10}!" puts "It's literally 10 times better!" end That worked fine, but if the user entered a number less than 10 the program ended. I want the user to be prompted to try again until they enter a number greater than 10. Am I supposed to do that with a loop? Here's what I took a swing at, but clearly it's wrong: puts "Hello there, and what's your favorite number?" favnum = gets.to_i puts "Your favorite number is #{favnum}?" " A better favorite number is #{favnum + 1}!" puts "Now, what's your favorite number greater than 10?" favnumOverTen = gets.to_i if favnumOverTen < 10 loop.do puts "Hey! I said GREATER than 10! Try again buddy." favnumOverTen = gets.to_i until favnumOverTen > 10 else puts "Your favorite number great than 10 is #{favnumOverTen}?" puts "A bigger and better number over 10 is #{favnumOverTen * 10}!" puts "It's literally 10 times better!" end

• Can I combine atom feeds from separate resources into one?

  - by stephemurdoch

  I have two resources for which I would like to generate feeds; they are called podcasts and posts. The problem is that when I include the auto_discovery_link in my templates, I have to add one for each of the two atom feeds that I've generated. The reason why this is a problem is that there are now two feeds for users to choose from, and most people probably won't realise that they need both so will only pick one. Is there a way to combine atom feeds from different resources into one atom feed? Like application.atom or something? I'm using builder to generate the feed.

• Roles authentication with Rails 3 and Devise.

  - by Oluf Nielsen

  Hi, first happy new year, may you make the best applications in 2011! So to my question, i have used devise ever since i got over to Rails 3, that was around the first or second beta, and now i also needs some Roles. So i searched the net, and i searched! And what i found was that CanCan should be the best solution. But i'm unsure if CanCan can manage my needs, like i want a forum moderator who can edit/destroy the topic, but the user who created the topic should also be able to edit, so how can i do that? Cheers, Oluf.

• Using colon syntax and variables in Sass

  - by corroded

  I am still using the old colon syntax (I prefer it more than the bracket syntax) and this particular code: a.button-link +box($main-color) +border-radius(5px) :background :color $main-color :color #fff :padding 5px generates a warning like so: DEPRECATION WARNING: On line 12, character 3 of '/Users/eumir/rails_apps/dxconnect/app/ stylesheets/partials/utilities/_link-styles.sass' Setting properties with = has been deprecated and will be removed in version 3.2. Use "background: $main-color" instead. I tried that but my background color still doesn't show up. Any help on this please? Thanks!

• rails expiring cache

  - by ash34

  Hi, I entered some products data into a table using a migration. I need to expire the page and fragment cache when I update, add, delete products from this table. I created a sweeper for this. class ProductSweeper < ActionController::Caching::Sweeper observe Product def after_create expire_cache end def after_save expire_cache end def after_update expire_cache end def after_destroy expire_cache end private def expire_cache expire_page(:controller => 'ProductsController', :action => 'index') expire_fragment 'listed_products' end end Then in script/console I update the product name and saved. When I reload my app in the browser it still gives me a cache hit. Cached fragment hit: views/listed_products (0.2ms) Can someone tell me how to expire this cache. I will not be adding, updating, deleting products through a controller action. thanks, ash

• Fully custom validation error message with Rails

  - by marcgg

  Using Rails I'm trying to get an error message like "The song field can't be empty" on save. Doing the following: validates_presence_of :song_rep_xyz, :message => "can't be empty" ... only displays "Song Rep XYW can't be empty", which is not good because the title of the field is not user friendly. How can I change the title of the field itself ? I could change the actual name of the field in the database, but I have multiple "song" fields and I do need to have specific field names. I don't want to hack around rails' validation process and I feel there should be a way of fixing that.

• Using named_scope with counts of child models

  - by Joe Cairns

  Hi, I have a simple parent object having many children. I'm trying to figure out how to use a named scope for bringing back just parents with specific numbers of children. Is this possible? class Foo < ActiveRecord::Base has_many :bars named_scope :with_no_bars, ... # count of bars == 0 named_scope :with_one_bar, ... # count of bars == 1 named_scope :with_more_than_one_bar, ... # count of bars > 1 end class Bar < ActiveRecord::Base belongs_to :foo end I'm hoping to do something like Foo.with_one_bar I could write methods on the parent class for something like this, but I'd rather have the power of the named scope

• Is there a way to make the flash[:notice] appear above, or before, the flash[:error] ?

  - by GoodGets

  So, I'd like to be able to display both a flash[:notice] and a flash[:error] on the same action, but I'd like for the :notice to always be displayed above (or before) the error. Is there a way to do this? In my controller, I thought I could just code the flash[:error] before the flash[:notice], so that rails will display it correctly, and it does a vast majority of the time. But every now and then they are randomly switched, and I can't seem to figure out why. So, how can I ensure that a flash[:notice] is always displayed above an :error ?

• How do you unpack gems using jruby on rails 2.3?

  - by James Moore

  I'm trying to unpack all the system gems to end up with a standalone Rails directory including all the rails gems and all the system gems. I'm starting with a bare rails setup; just did a jruby -S rails and a 'generate jdbc'. I then add a config.gem 'jdbc-mysql' to environment.rb and do the jruby -S rake gems:unpack:dependencies. After unpacking, if I do a rake I get: no such file to load -- jdbc-mysql Is there something else you need to do to get the jdbc gem unpacked? I'm using jruby 1.4.0 (and moving to 1.5 is on my todo list) and rails 2.3.8.

• Creating a gallery in Rails

  - by raphael_turtle

  I'm creating a simple site with a gallery. I have a photos model which has a page for each photo with it's info and an image. I'm unsure how to create a gallery from the photo's. The gallery model has_many photos, the photos model has_and_belongs_to_many galleries. I thought of adding a gallery.title field on each photo page so I'd have a list of photo's for each gallery then display them in a view. Is this a good way to make a gallery? (I've looked through the code on some gallery apps on github, but most are outdated are too complicated for my needs.)
