prefix disallows trailing slashes?
by Brian E. Lozier 22 Mar '11

22 Mar '11

I had a bunch of stuff in one app and today I upgraded Dancer to latest and made sure everything worked, then I split out the main stuff "prefix undef;" into MyApp::Web::Root and then my "forums" stuff into MyApp::Web::Forum with prefix '/forums'; When I did this, my routes under /forums (other than "/") don't allow the trailing slashes anymore. For example, I have a route: any '/:name/new_topic/' => sub { ... }; But if I access /forums/some_name/new_topic/ I get Error 404. If I change it to /forums/some_name/new_topic (note missing trailing slash) it works. So it seems that having trailing slashes in routes works under prefix undef; but doesn't work (properly) under other prefixes. Thanks, Brian

Serving DirectoryIndex via Dancer fails
by Mr. Puneet Kishor 17 Mar '11

17 Mar '11

My web site, [http://punkish.org] is Dancer powered (or, I should say, "proudly powered by Dancer"). However, from time to time, I create small, static, "micro-sites" under the same URI. For example, see [http://punkish.org/geoweb/index.html] or [http://punkish.org/opengov/index.html] I serve these micro-sites from eponymous folders under /path/to/punkish/public/, so, for example, /path/to/punkish/geoweb and /path/to/punkish/opengov, etc. My httpd.conf is set to serve DirectoryIndex index.html and index.cgi. Yet, if I go to [http://punkish.org/geoweb] or [http://punkish.org/opengov] Dancer thinks I am trying to query for a page called geoweb or opengov -- I was under the impression that it would first see if by adding a trailing slash to the requested URI, it could located static directory. And, if I go to [http://punkish.org/geoweb/] or [http://punkish.org/opengov/] Dancer gives me a 404 error. I *have* to specify that I am looking for index.html in order to serve the static files. Is there a way to fix this? A fix, in my view, would be -- http://punkish.org/foo would be suffixed with a trailing slash and checked if a directory called foo exists. If it does, then the specified directory index would be served. If the directory doesn't exist, then Dancer would do its magic to determine how to serve the content request via foo. I am using Apache2 with vhosts. Puneet.

Serving DirectoryIndex in non-dancer/static files fails

newbie question, conversion from cgi's to dancer
by Martin Bower 16 Mar '11

16 Mar '11

Hi, I've been looking at dancer for a while, it looks great and I'm now hooked. I'd like to start to replace my current setup, but am not sure in which direction to proceed. My current site is a collection of scripts, running under Apache as seperate cgi's. I use TT for the site, with all cgi's accessing Sybase behind the scenes. My questions are: - 1. Should I run a single occurrence of dancer to handle the site, and have that control everything ? 2. If I shouldn't run one main controller, how do I run them seperately under port 80 ? 3. I'd like to keep my scripts seperate, how can I implement this within Dancer? the examples I've seen so far seem to have all the code in the same place, and seem to be one dancer application for each app (as per my cgi setup) 4. Currently Apache caches the DB connections and they are shared across the scripts, this is fast and easy to use. How would I replicate that? Apologies if any of the questions are basic, but I read the cookbook, introduction and Tutorial and they didn't seem to answer the above. Thanks in advance.

How to un-prettify JSON?
by Alastair Sherringham 16 Mar '11

16 Mar '11

Hello, I just upgraded from Dancer 1.2 to latest (1.3XX) and my JSON output changed from un-pretty to pretty. set serializer => 'JSON'; get '/products' => sub { return db_products(); }; I see the option in the docs but cannot figure out how to use it. In "config.yml", I tried : engines: JSON: pretty: 0 But that makes no difference. How do I turn off "pretty"? Cheers, -- Alastair Sherringham http://www.sherringham.net

How to use dancer functions in other modules
by Brian E. Lozier 14 Mar '11

14 Mar '11

I have some modules for form generation and processing that aren't Dancer classes (in that they don't contain any routes). Inside these I'd like to use some of the dancer functions like "params." When I "use Dancer" at the top of one of these modules I am getting a really odd error message. runtime error Operation "eq": no method found, left argument in overloaded package Fan::Form::Register, right argument has no overloaded magic at /usr/local/lib/perl5/site_perl/5.12.3/Dancer/Request.pm line 177. /usr/local/lib/perl5/site_perl/5.12.3/Dancer/Request.pm around line 177 174 return %{$self->{params}} if wantarray && @_ == 1; 175 return $self->{params} if @_ == 1; 176 177 if ($source eq 'query') { 178 return %{$self->{_query_params}} if wantarray; 179 return $self->{_query_params}; 180 } In my main Dancer class, Fan::Web, I have a route sub that says: my $params = params(); I then pass this hashref into my form module like this: my $form = Fan::Form::Register->new($params); If I don't "use Dancer" in the form module, all works well. If I "use Dancer;" in the form module I get the error message. I am trying to use Dancer so I can use the debug/warning functions. I don't understand the error message. I have an overloaded "" operator in the form class (to return an HTML representation of the form) but I don't know how calling the params() function in my main Dancer routes class (Fan::Web) and then passing the hashref into my form class can cause an error like this. Any thoughts? Thanks, Brian

Fwd: hashes in POST form data
by Jury Gorky 14 Mar '11

14 Mar '11

well, you can try something like this: use CGI::WebIn; foreach (keys params) { CGI::WebIn::_processPar($_, params->{$_}); } # %CGI::WebIn::IN should now contain all you need but this module sucks really hard On 14 March 2011 19:56, Nick Knutov <mail(a)knutov.com> wrote: > Hello, > > are there any ready modules for Dancer that can parse post data from forms > with hashes in names like CGI::WebIn? > > I really need to be able to do > <input type=text name="Address{Russia}{Moscow}" value="house"> or <input > name='zone{}' type='checkbox' value='com'> > and to get something like > parameters('body')->{Address}->{Russia}->{Moscow}. > > -- > Best Regards, > Nick Knutov > http://knutov.com > ICQ: 272873706 > Voice: +7-904-84-23-130 > _______________________________________________ > Dancer-users mailing list > Dancer-users(a)perldancer.org > http://www.backup-manager.org/cgi-bin/listinfo/dancer-users >

hashes in POST form data
by Nick Knutov 14 Mar '11

14 Mar '11

Hello, are there any ready modules for Dancer that can parse post data from forms with hashes in names like CGI::WebIn? I really need to be able to do <input type=text name="Address{Russia}{Moscow}" value="house"> or <input name='zone{}' type='checkbox' value='com'> and to get something like parameters('body')->{Address}->{Russia}->{Moscow}. -- Best Regards, Nick Knutov http://knutov.com ICQ: 272873706 Voice: +7-904-84-23-130

Forms with dancer
by Erik Colson 13 Mar '11

13 Mar '11

Ehlo, I'm about to write a company app with dancer. I've been reading a lot about Formhandler, Formbuilder and Formfu. There are pros and cons for everyone of these :/ So, my question is a double popularity poll: . which form generator are you using ? . which form generator is still (actively) maintained ? Of course, I'm especially interested for the answers of the core developers of dancer ;) best -- erik colson ecocode.net
