What is object here in ...if object.respond_to?("errors") && object.errors.respond_to?("on")...
http://dev.rubyonrails.org/browser/trunk/actionpack/lib/action_view/helpers/active_record_helper.rb
Line no: 151
alias_method :tag_without_error_wrapping, :tag
def tag(name, options)
if object.respond_to?("errors") &&
object.errors.respond_to?("on")
error_wrapping(tag_without_error_wrapping(name, options), object.errors.on
(@method_name))
else
tag_without_error_wrapping(name, options)
end
end
What''s "object" in there? In this case object is instance of
what?

Hi Neeraj, Hopefully, object will be an instance of a model that you assigned in your controller''s action. See http://dev.rubyonrails.org/browser/trunk/actionpack/lib/action_view/helpers/form_helper.rb#L242 (form_helper.rb, line 242) for the definition of the InstanceTag#object method. FYI, the ''@object_name'' that is referenced on line 243 is the name of the object that you passed into the specific InstanceTag method. For instance, if you did a: text_field :user, :name then @object_name will be ''user'' and the InstanceTag#object method will yield the value of whatever was assigned to ''@user'' in your controller. -Doug On 11/3/05, Neeraj Kumar <neeraj.jsr-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> http://dev.rubyonrails.org/browser/trunk/actionpack/lib/action_view/helpers/active_record_helper.rb > > Line no: 151 > > alias_method :tag_without_error_wrapping, :tag > def tag(name, options) > if object.respond_to?("errors") && > object.errors.respond_to?("on") > > error_wrapping(tag_without_error_wrapping(name, options), > object.errors.on(@method_name)) > else > tag_without_error_wrapping(name, options) > end > end > > > > What''s "object" in there?
