Problem

• Evil hackers try to insert html/script into model fields
• Too long texts, and any other sort of stuff we need to take care of...

Solution

Before asignment apply text filters to the value. To use something like strip_tags here you should define it on String see ActionView helpers on String

Usage

• As Rails plugin script/plugin install git://github.com/grosser/text_filter.git
• As gem sudo gem install text_filter

Example: class Product < ActiveRecord::Base text_filter :title, :description, :with => :strip_tags #=> on each assign: product.title = product.title.strip_tags text_filter :summary, :with => [:strip_tags, {:truncate=>5}] #=> on each assign: product.summary = product.summary.strip_tags.truncate(5) end

Note: with a multi-key-hash in :with order of execution is random (before ruby 1.9), e.g. :truncate=>10, :something_else=>[1,2]
