I'm having problems using url_for in a controller. The original method
looks like this, but the @controller variable is unknown in this
context. However if I remove it, it goes in an endless loop for the
Hash case. Anyone?
def url_for(options = {})
options ||= {}
url = case options
when String
escape = true
options
when Hash
options = { :only_path =>
options[:host].nil? }.update(options.symbolize_keys)
escape = options.key?(:escape) ? options.delete(:escape) :
true
@controller.send(:url_for, options)
when :back
escape = false
@controller.request.env["HTTP_REFERER"] ||
'javascript:history.back()'
else
escape = false
polymorphic_path(options)
end
escape ? escape_once(url) : url
end
