I have a Dancer app with a registration form and a database. Testing produces this error message:

Cannot bind a reference

Nothing under Stack relates to the code I've written so all I have to go on is "Cannot bind a reference". Not much detail there, either.

I would help if you post your source code for your Dancer application.

This - without seeing the code, we're guessing. However, a quick google for "Cannot bind a reference" suggests it's an error you get from DBI when you mistakenly pass a reference as a bind var when executing a query - so check what vars you're using (whether you're using DBI directly, or using Dancer::Plugin:Database). -- David Precious ("bigpresh") <davidp@preshweb.co.uk> http://www.preshweb.co.uk/ www.preshweb.co.uk/twitter www.preshweb.co.uk/linkedin www.preshweb.co.uk/facebook www.preshweb.co.uk/cpan www.preshweb.co.uk/github

Most of my code in modules except routing: ************************** package Astro::Routes; use Dancer qw(:syntax); use Astro::Planets; use Astro::Login; use Astro::Logout; use Astro::Register; use Astro::Astrologers; post '/register' => sub { my %params = params; my %val = %{Astro::Register::run(\%params)}; if ($val{passed}) { redirect '/response/registered.html' } else { template 'input_errors', { missing => $val{missing}, invalid => $val{invalid}, unknown => $val{unknown} }} }; post '/login' => sub { Astro::Login::run }; post '/planets' => sub { Astro::Planets::run }; post '/logout' => sub { Astro::Logout::run }; get '/astrologers' => sub { Astro::Astrologers::run }; 1; ******************************** The registration form submission which produced the error hits the '/register' route. gvim

That's the problem. Astro::Register in turn uses other custom modules but Dancer doesn't seem to be able to reveal the details of the binding error. I would have to send you the code for the whole application, which isn't realistic. gvim

Shouldn't Dancer's error traceback include the user code? i put the request into the bug tracker long ago, but no comments. Do you see a technical reason for not show user code too? (i dont, and in my non-dancer code it works that way). Niels L On Mon, 2013-06-03 at 20:10 +0100, David Precious wrote:

Well, I've at least pointed at the likely cause.

You could try running your app under Carp::Always to make warn/die provide stack traces, e.g.

perl -MCarp::Always bin/app.pl

That might help.

Of course, it's not helpful if Dancer isn't giving you a stack trace with show_errors on - I'll see if I can reproduce that.

Can you reduce it to a minimal example that shows the error? Of course, by doing that you'll probably find that the error leaps off the screen at you and you don't need to send it anyway. -- David Cantrell | Bourgeois reactionary pig There is no one true indentation style, But if there were K&R would be Its Prophets.
