3 ways to disable auto typing in SOAP::Lite client

Often SOAP::Lite will try to autotype a parameter in a request and it does it wrongly (or correctly) causing the SOAP server to fail badly (for so many reasons).

SOAP::Lite provides three ways to disable this typing. Two of the ways work at the client object level and the other does it at the SOAP::Data object level.

Client Level

The following options disable autotyping for all data items in a request:
  • autotype method. After creating a SOAP::Lite client you can disable autotyping by $soapclient->autotype(0).
    Example: 
    my $soap = SOAP::Lite->uri($xmlns)->proxy($proxy)
     ->on_action( sub {"$action?type=$reqname&ns=$xmlns"} );
    $soap->autotype(0);
  • Overriding the typelookup method. You can override the typelookup to run undef/false/etc.
    Example:
    sub typelookup { return undef; }

Data object

SOAP::Data object provide a type method. This allows manually typing of the object. When this is set to an empty string no type is set nor is it autotyped by serializer. Note: undef doesn't work you must use empty string.

Here is an example:
my $range = SOAP::Data->name(
  'DateRange' => \SOAP::Data->value(
    SOAP::Data->name( 'StartDate' => $start )->type(''),
    SOAP::Data->name( 'EndDate'   => $end )->type('')
);
Someone else suggested creating SOAP::Data object directly from XML in this cause type is set to whatever value is included in the XML document.

Thanks the SOAP::Lite mailing list for the some of the ideas.

Template Toolkit Debugging inside of Perl Dancer

The other day someone was asking how to enable Template Toolkit debugging inside of Perl Dancer in the #dancer IRC channel, it seemed like a good time for a write up. The template engine configuration directive supports passing through various options like start_tag and stop_tag as explained in Dancer::Template::TemplateToolkit POD. And alludes to being able to pass other options. How To pass TT options like those found in Template::Constants , there must be a DEBUG section in engines -> template_toolkit , usually found in config.yml . Example Snippet Here is an example: A few notes Remove leading DEBUG_ from TT constants. The option DEBUG_PLUGINS becomes plugins . Multiple options can be separated with a comma. Example: DEBUG: "provider,plugins" . Be warned, some of these options can lead to tons of information :) __END__

BootstrapX clickover

Birth The last few weeks, i've been pushing Bootstrap in various directions. Most of the time, its being hacking around Popovers. Our current design uses Popovers with forms. It provides a very nice balance between in page action and more subtle interruption to viewing the page than a modal. Over the last few weeks, I've found a few quirks with using Popover's trigger action of 'focus'. This works fine with forms but on Chrome and Safari 'focus' events are supported incompletely . In addition to that varied support we have a few other needs that inspired a new Bootstrap extension. BootstrapX - Clickover . Our requirements are: Click button/link/icon to toggle display of popover content Option to click 'away' from popover to close Ability to have 'popover' autoclose after some amount of time Option to have element inside of popover hide it I suspect, in the future, it will need to only auto close when user's mouse

Changing Dancer::Plugin::Ajax's content type

Dancer does lots of great things. It has a nice clean way to define routes to handle AJAX routes using the plugin Dancer::Plugin::Ajax . ajax routes are defined in a clear way: ajax '/stuff' => sub { # do work and return }; This plugin technique allows for clear way to separate between ajax and other types of actions for the same route. ajax '/stuff' => sub { # do ajax-y stuff here }; get '/stuff' => sub { # handle html response }; Unfortunately, the one negative with Dancer::Plugin::Ajax is that is assumes all responses will be XML. A quick fix is to manually set the content type in each ajax handler. ajax '/stuff' => sub { content_type('application/json'); # do work }; or add set it as a general option in your main before hook or in each prefix route handler like: package WebApp; hook before => sub { if ( request->is_ajax ) { content_type('application/json'); } };
