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
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.
Or install manually with:
sudo gem install string-utils –source gemcutter.org
Applies the sanitize helper to text. Works not only in views but also in models, controllers and libs!
Shortcut for my_unsafe_text.sanitize
“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.
