Non-Message Flash in Rails | Collective Idea
Flash messages were one of those little features that amazed me when I was first introduced to Rails. Developers often use Rails' flash to display messages to their users, but messages aren't the only reason to use flash. A typical interaction with flash looks something like this in the controller: class OrdersController < ApplicationController def new @order = Order.new end def create @order = Or
Running a high volume Rails app on Heroku for free | Collective Idea
Update: Heroku has now posted a more complete Unicorn setup here In 3 easy steps you can setup a rails app on Heroku that can easily handle 200 requests per second and 100 concurrent connections, for free. Step 1: Use Unicorn With the Cedar stack on Heroku, you can now run any process, so why not use Unicorn. Here’s how to set this up. Add this to your Gemfile group :production do gem 'unicorn' en
You Still Have to Test on the Server | Collective Idea
How many times has this happened to you: You get some code working locally, have an awesome test suite that covers all the possible code paths, you deploy and tell your client/boss, and they come back with “I got an error right away, don’t you test this stuff?!?” It is crushing to hear, and frustrating because no matter how great your test suite was, something went wrong and you look like a fool.
Where's Your Business Logic? | Collective Idea
If I sat down with your code base and asked you how such-and-such a feature is implemented, what would you say? Would you lead me through controller filters and actions? What about model methods, includes, callbacks or observers? How about objects in lib/ (oh, and there’s also this other call to a mailer to make sure emails get sent out…), or would you even dive down into the database itself? Or w
Slow it Down | Collective Idea
Most of the time, you test your apps on a fast connection, especially when working on a local machine. Most of your clients/visitors/customers aren’t so lucky, but how do you simulate their connection speed? If you have installed Xcode on Lion, you have access to a very cool tool called Network Link Conditioner[1]. It is a preference pane, but not installed by default. You’ll find it in /Developer
Install Ruby 1.9.3 with libyaml on CentOS | Collective Idea
Ruby 1.9.3-p0 makes psych—the replacement for 1.8.7’s YAML library, Syck—the default YAML parser. Psych is a wrapper around libyaml, so you’re going to need it installed and configured before installing Ruby. If you install 1.9.3-p0 without libyaml, you’ll see warnings like this: It seems your ruby installation is missing psych (for YAML output). To eliminate this warning, please install libyaml a
Use Chrome with Cucumber & Capybara | Collective Idea
Photo by Tambako the Jaguar, used under Creative Commons https://flic.kr/p/dJD2dV We frequently swap out Firefox for Chrome in our selenium (@javascript) cucumber tests. It is actually very easy, but not widely known. Update: I got some questions about why we’d use Chrome. Speed hasn’t been the issue (use capybara-webkit for that) but we have found some things that work better in Chrome vs Firefox
