string-utils gem

This small extension enables string sanitization in models and controller.

Contains a workaround for Rails sanitize helper that (as any helper) works only in views, allowing you to call my_text.sanitize also in controllers, models and libs.

Provides also a function for making url friendly strings removing all unwanted characters.

Basically it adds some methods and shortcuts to the String class, see the example section for usage.

Works with Rails ~> 2.3.6 and ~> 3.0.0 Tested on Ruby 1.8.7 and 1.9.2

Install

Specify it in your Rails project config/environment.rb under the “Rails::Initializer.run do |config|” block

config.gem 'string-utils', :source => “gemcutter.org

Then install it from the console.

rake gems:install

Or install manually with:

sudo gem install string-utils –source gemcutter.org

Examples

Applies the sanitize helper to text. Works not only in views but also in models, controllers and libs!

my_unsafe_text.sanitize

Shortcut for my_unsafe_text.sanitize

my_unsafe_text.san

“Fire in the hole: <script>alert('bam!');</script>”.san “Fire in the hole: ”

“Some tags: <asdasd>an asdasd tag</adsasd>”.san “Some tags: an asdasd tag”

Shortcut for my_SAFE_text.html_safe USE WITH CAUTION Forces the string to be html safe so it won't be escaped. Useful for quick-and-dirty monkey scripting in views. my_SAFE_text.hs

message = “I really need this <script>alert('popup')</script>”.hs “I really need this <script>alert('popup')</script>” message.html_safe? true

urlify is a function for making url friendly strings removing all unwanted characters.

“My really great post”.urlify “my-really-great-post”

“O come l'è GANZA 'sta gemma!”.urlify “o-come-l-e-ganza-sta-gemma”
