Stripping HTML Tags from your ActiveModel Model
Finally a Rails post! This one is short, basic, and probably has a bunch of other examples on the net.
Rails3 escapes HTML by default, so this isn’t strictly necessary, but I still believe that what goes into the datastore should be clean. After all, the data will probably last longer than the front-end.
I found this post that explains how to do it for your ActiveRecord models. However, I don’t have columns. Instead I used the following before_filter in my model class.
before_save :sanitze_html
def sanitze_html
@attributes.each_key do |attr|
value = @attributes[attr]
if(value.class == String)
@attributes[attr] = strip_tags(value)
end
end
end
It’s the same idea, but instead use the attribute map to pull the objects out. If it’s a String type, call strip_tags.
