I am writing an application where I know that I do not need to allow any HTML input from a user. I am considering using before_filter at the controller level to call a method that essentially performs the following on the appropriate members of the params hash: - call strip_tags() - escape any remaining characters with h() The reason why I am doing this is it seems repetitive and error prone to have to call the above method every time in a view where user input is being displayed. Ultimately, I would prefer to store the data in as "non-malicious" format as possible and not have to worry at the presentation level of escaping that data at a later time. Is there a better way to do this? Is there existing code that does this already? Some googling yielded nothing specific other than postings to the effect of "in your view, make sure to use h()".

Oh woops, my mistake! Meant to send this to the Rails list.
