Comments on: Good Error Messages Point the Way http://www.postal-code.com/binarycode/2008/05/31/good-error-messages-point-the-way/ A whole bunch of nought thought by Chris Cummer Sat, 06 Jun 2009 22:54:39 +0000 hourly 1 http://wordpress.org/?v=3.0.1 By: chris http://www.postal-code.com/binarycode/2008/05/31/good-error-messages-point-the-way/comment-page-1/#comment-4136 chris Tue, 30 Dec 2008 18:05:33 +0000 http://www.postal-code.com/binarycode/?p=208#comment-4136 Well, I do actually describe the solution, just not as a single block of code. I suppose I could have been more clear. If you get this error above you actually do need to over-ride the allow_to method in your controller and call super() from within it, like so: controller Blah def allow_to() # Do your own stuff here super() end end From the Loved By Less source we see this sort of example: protected def allow_to super :all, :all=>true end We need to call super() because that throws the call back up to the ApplicationController which has: def allow_to( level = nil, args = {} ) return unless level @level ||= [] @level << [level, args] end the block of code that handles permissions for actions in the project.

If you get this error above you actually do need to over-ride the allow_to method in your controller and call super() from within it, like so:

controller Blah
def allow_to()
# Do your own stuff here
super()

From the Loved By Less source we see this sort of example:

protected
def allow_to
super :all, :all=>true
end

We need to call super() because that throws the call back up to the ApplicationController which has:

def allow_to( level = nil, args = {} )
return unless level
@level ||= []
@level << [level, args]
end

the block of code that handles permissions for actions in the project.

Mediocre ones hint at the content. Good blog posts point the way to a better day." ;-) ok, good point about the nature and evolution of error messages. and i’m happy i found your post, thanks man.
