In "Agile Web Development with Rails" (third edition) page 537 - 541 it has "Custom Form Builders" code as follows:
class TaggedBuilder < ActionView::Helpers::FormBuilder
# <p> # <label for="product_description">Description</label><br/> # <%= form.text_area 'description' %> #</p>
def self.create_tagged_field(method_name)
define_method(method_name) do |label, *args|
@template.content_tag("p" , @template.content_tag("label" , label.to_s.humanize,
:for => "#{@object_name}_#{label}") + "<br/>" + super)
end
end
field_helpers.each do |name|
create_tagged_field(name)
end
end
This code doesn't work with Ruby 1.9.1. It returns error as follows:
implicit argument passing of super from method defined by define_method() is not supported. Specify all arguments explicitly. (ActionView::TemplateError)
My question is: What should I change in the code to fix this?
The super
above passed all parameters (see this recent question).
As the error message states, you must here "specify all arguments explicitly". Replace super
with super(label, *args)
.
