Re: [dancer-users] Form validation framework

Dear Octavian and Warren, thank you for your comments. I am sorry if my formulation was unclear. I certainly do need to do server side validation since - as you point out - an attacker might circumvent the user interface. Since the validation is rather complex I don't want to duplicate (all of) it on the client side. Still I would like to give the user as good an experience as possible. Cheers, Lutz

Form validation framework
by Lutz Gehlen 15 Apr '14

15 Apr '14

Hello all, is there a generally recommended form validation framework for Dancer? There are several plugins on CPAN, but they all seem to be rather basic (at least on first glance). A key feature for me is that error messages can be easily displayed together with the respective input fields and not only as a group of error messages. Which plugin do you use or do you use your own form validation code? Thanks for your help, Lutz

Hooks throwing exceptions
by David Cantrell 14 Apr '14

14 Apr '14

I have an 'on_route_exception' hook defined in my application, which does useful things like logging what happened, but boils down to ... hook 'on_route_exception' => sub { my $exception = shift; status($exception->status() || HTTP_INTERNAL_SERVER_ERROR); halt({ error => $exception->data() }); } I also have a 'before' hook defined that checks things like whether the object a user is asking for belongs to them or not, and if it doesn't calls status() and halt() appropriately. But I would like to have the 'before' hook just throw an exception object like the rest of my code. However, if I do, the 'on_route_exception' hook never triggers and the exception eventually just gets stringified which isn't very useful. Is there some other hook I should be using instead of 'on_route_exception'? -- David Cantrell | Minister for Arbitrary Justice You can't spell "slaughter" without "laughter"

SimpleCRUD question
by Rene Stoutjesdijk 12 Apr '14

12 Apr '14

Hi All, first let me say that i'm not an experienced dancer user. My experience for now is that it really works :). I've just started to use the SimpleCRUD plugin, which makes live very easy for this kind of actions. I do have 2 related questions which i don't know how to resolve: 1) can i remove the option to add an entry in the database, as i would only want the users to do an edit action (delete was easy to remove as it's a configurable parameter). 2) can i have somewhere the option to filter (eg by a where clause in mysql) based upon the login credentials? I would like to limit the table view by a where clause based upon the login name. thx in advance for your response.

authentication with tokens
by WK 11 Apr '14

11 Apr '14

Tere! I am looking for solution how handle requests simply and securely for RESTful web-service. Theoretically it should look like this: 1. on first approach client should log in with usual credentials (like username and password) 2. system generates unique token and returns it to client 3. on every subsequent request client uses token to identify itself 4. when token ages, client starts from first point again I tried some queries on metacpan and google, but did not find nothing involving Dancer and even Perl as whole. Do you have some hints for me, where to look? To implement it with one table seems not too hard, but to have something battleproofed and abstracted out would be appreciated. TIA, -- Wbr, Kõike hääd, Gunnar

Dancer::SessionFactory::Memcached released
by David Golden 10 Apr '14

It's amazing how little code is needed with Moo and the role. Mostly, it just delegates everything. https://github.com/dagolden/dancer-sessionfactory-memcached/blob/master/lib… David -- David Golden <xdg(a)xdg.me> Take back your inbox! → http://www.bunchmail.com/ Twitter/IRC: @xdg
