Sanitizer

[bluesnotred]

I needed to sanitize my strings for each locale, which was difficult to implement at the model level.

That’s why I introduced an option called :sanitizer at the multilang attribute level. It accepts a custom sanitizer method, which is being called for all locales of a certain attribute.

Example sanitizer methods:

def self.squish(value)
  value.squish!
end

def self.sanitize_html(value)
  value.gsub!(/<\/?[^>]*>/, '')
end

Setting the sanitizer options:

multilang :title, sanitizer: method(:squish)
multilang :body,  sanitizer: method(:sanitize_html)

The sanitizer method is both called on read and write to make sure unsanitized content (which could be already stored in db before activating the sanitizer option) is always displayed as sanitized content.
