Skip HTML escape in custom label_tag helper in Rail 3
- by tricote
Hi,
I have this nice class ErrorFormBuilder that allows me to add the error description near the corresponding field in the form view :
class ErrorFormBuilder < ActionView::Helpers::FormBuilder
#Adds error message directly inline to a form label
#Accepts all the options normall passed to form.label as well as:
# :hide_errors - true if you don't want errors displayed on this label
# :additional_text - Will add additional text after the error message or after the label if no errors
def label(method, text = nil, options = {})
#Check to see if text for this label has been supplied and humanize the field name if not.
text = text || method.to_s.humanize
#Get a reference to the model object
object = @template.instance_variable_get("@#{@object_name}")
#Make sure we have an object and we're not told to hide errors for this label
unless object.nil? || options[:hide_errors]
#Check if there are any errors for this field in the model
errors = object.errors.on(method.to_sym)
if errors
#Generate the label using the text as well as the error message wrapped in a span with error class
text += " <br/><span class=\"error\">#{errors.is_a?(Array) ? errors.first : errors}</span>"
end
end
#Add any additional text that might be needed on the label
text += " #{options[:additional_text]}" if options[:additional_text]
#Finally hand off to super to deal with the display of the label
super(method, text, options)
end
end
But the HTML :
text += " <br/><span class=\"error\">#{errors.is_a?(Array) ? errors.first : errors}</span>"
is escaped by default in the view...
I tried to add the {:escape = false} option :
super(method, text, options.merge({:escape => false}))
without success
Is there any way to bypass this behavior ?
Thanks
