How to remove/disable the automatic XSS protection helper html escaping for Rails 3.

This is probably a horrible idea.

See attached link for a way to extract the conditions of a named scope in Rails 2.3.

Let’s take a look at what you need to do to get your app ready for Rails 4.

The asset pipeline from Rails 3.1 packported to 2.3. By Michael Grosser from parallel_tests fame.

This sounds promising:

The best part from the Rails side, is that you don’t have to change anything at all in your code to swap a varchar out for an ENUM.

How to call routes, make requests and try out helpers from the Rails console.

A possible way for localisation in Rails applications that allows editing translations remotely.

I still see people promoting various gems and plugins to handle miscellaneous configuration elements for your application. One little known secret is that Rails 3 allows you to define your own configuration elements trivially.

Recently, we had an interesting lunch-break with the rails 3.1. asset-pipeline in production mode. Daniel Zahn made a blogpost about our journey, precompiling assets, fingerprinting, Haml, Sass & Compass and what he calls "the dark heinous hutch".

Most web applications contain several examples of state machines, including accounts and subscriptions, invoices, orders, blog posts, and many more. The problem is that you might not necessarily think of them as state machines while designing your application. Therefore, it is good to have some indicators to recognize them early on. The easiest way is to look at your data model.

XPath matchers can be combined with CSS-selector matchers. This is really useful if not, for example, the content of an element should be matched but the element itself like in the following example. Here a form is used to display data as default value in its input elements. This can be the case in web applications in which data should be edited easily without additional clicks.

In an environment:

config.logger = Logger.new('/dev/null')

The rack-contrib gem brings a JSONP middleware that just works™. Whenever a JSON request has a callback parameter, it will wrap the application's JSON response appropriately.

The project is a bit dated, but the JSONP middleware is ok.

rack-mini-profiler is a powerful Swiss army knife for Rack app performance. Measure SQL queries, memory allocation and CPU time.

This should probably not be loaded in production (the article recommends otherwise), but this looks like a useful tool.

Amazing guide how to divide a ball of Javascript spaghetti distinct separate layers (model, view, controller, backend adapter).

It does not use a Javascript framework.

quiet_assets helps with disabling asset pipeline log messages in the development log. When the gem is added, asset pipeline logs are suppressed by default.

If you want to disable muting temporarily, add config.quiet_assets = false to your config/application.rb.

Declare an enum attribute where the values map to integers in the database, but can be queried by name.

I recently had a need to demonstrate a data-heavy application to potential customers. Demonstrating the application with bogus numbers is one thing, but everything looks much more realistic when I’m using real data. I can’t reveal any real information, though, so I needed a quick way to obfuscate real names. Faker to the rescue!

Installation differs slightly from older versions, please check the README.

Updated the card with our current best practice (shared app code and specs via symlinks).

There is now a solution.
