269 | =head1 DESCRIPTION |
270 | |
271 | This is the Catalyst view class for the L<Template Toolkit|Template>. |
272 | Your application should defined a view class which is a subclass of |
273 | this module. The easiest way to achieve this is using the |
274 | F<myapp_create.pl> script (where F<myapp> should be replaced with |
275 | whatever your application is called). This script is created as part |
276 | of the Catalyst setup. |
277 | |
278 | $ script/myapp_create.pl view TT TT |
279 | |
6229ce0d |
280 | This creates a MyApp::View::TT.pm module in the F<lib> directory (again, |
8cd017a8 |
281 | replacing C<MyApp> with the name of your application) which looks |
282 | something like this: |
283 | |
6229ce0d |
284 | package FooBar::View::TT; |
f5b61ad7 |
285 | |
8cd017a8 |
286 | use strict; |
c18eae32 |
287 | use warnings; |
f5b61ad7 |
288 | |
c18eae32 |
289 | use base 'Catalyst::View::TT'; |
8077080c |
290 | |
a1b7968f |
291 | __PACKAGE__->config(DEBUG => 'all'); |
8077080c |
292 | |
8cd017a8 |
293 | Now you can modify your action handlers in the main application and/or |
294 | controllers to forward to your view class. You might choose to do this |
295 | in the end() method, for example, to automatically forward all actions |
296 | to the TT view class. |
722fede4 |
297 | |
8cd017a8 |
298 | # In MyApp or MyApp::Controller::SomeController |
f5b61ad7 |
299 | |
8cd017a8 |
300 | sub end : Private { |
94b3529a |
301 | my( $self, $c ) = @_; |
c18eae32 |
302 | $c->forward( $c->view('TT') ); |
8cd017a8 |
303 | } |
8077080c |
304 | |
2844488f |
305 | But if you are using the standard auto-generated end action, you don't even need |
306 | to do this! |
307 | |
308 | # in MyApp::Controller::Root |
309 | sub end : ActionClass('RenderView') {} # no need to change this line |
310 | |
311 | # in MyApp.pm |
312 | __PACKAGE__->config( |
313 | ... |
314 | default_view => 'TT', |
315 | ); |
316 | |
317 | This will Just Work. And it has the advantages that: |
318 | |
319 | =over 4 |
320 | |
321 | =item * |
322 | |
323 | If you want to use a different view for a given request, just set |
324 | << $c->stash->{current_view} >>. (See L<Catalyst>'s C<< $c->view >> method |
325 | for details. |
326 | |
327 | =item * |
328 | |
329 | << $c->res->redirect >> is handled by default. If you just forward to |
330 | C<View::TT> in your C<end> routine, you could break this by sending additional |
331 | content. |
332 | |
333 | =back |
334 | |
335 | See L<Catalyst::Action::RenderView> for more details. |
336 | |
8cd017a8 |
337 | =head2 CONFIGURATION |
4687ac0d |
338 | |
8cd017a8 |
339 | There are a three different ways to configure your view class. The |
340 | first way is to call the C<config()> method in the view subclass. This |
341 | happens when the module is first loaded. |
8077080c |
342 | |
6229ce0d |
343 | package MyApp::View::TT; |
f5b61ad7 |
344 | |
8cd017a8 |
345 | use strict; |
346 | use base 'Catalyst::View::TT'; |
722fede4 |
347 | |
6229ce0d |
348 | MyApp::View::TT->config({ |
7d8aa5ec |
349 | INCLUDE_PATH => [ |
350 | MyApp->path_to( 'root', 'templates', 'lib' ), |
351 | MyApp->path_to( 'root', 'templates', 'src' ), |
352 | ], |
8cd017a8 |
353 | PRE_PROCESS => 'config/main', |
354 | WRAPPER => 'site/wrapper', |
355 | }); |
356 | |
357 | The second way is to define a C<new()> method in your view subclass. |
358 | This performs the configuration when the view object is created, |
359 | shortly after being loaded. Remember to delegate to the base class |
e8693f1b |
360 | C<new()> method (via C<$self-E<gt>next::method()> in the example below) after |
8cd017a8 |
361 | performing any configuration. |
362 | |
363 | sub new { |
364 | my $self = shift; |
365 | $self->config({ |
7d8aa5ec |
366 | INCLUDE_PATH => [ |
367 | MyApp->path_to( 'root', 'templates', 'lib' ), |
368 | MyApp->path_to( 'root', 'templates', 'src' ), |
369 | ], |
8cd017a8 |
370 | PRE_PROCESS => 'config/main', |
371 | WRAPPER => 'site/wrapper', |
372 | }); |
e8693f1b |
373 | return $self->next::method(@_); |
8cd017a8 |
374 | } |
f5b61ad7 |
375 | |
94b3529a |
376 | The final, and perhaps most direct way, is to define a class |
8cd017a8 |
377 | item in your main application configuration, again by calling the |
ad50568f |
378 | ubiquitous C<config()> method. The items in the class hash are |
8cd017a8 |
379 | added to those already defined by the above two methods. This happens |
380 | in the base class new() method (which is one reason why you must |
f5b61ad7 |
381 | remember to call it via C<MRO::Compat> if you redefine the C<new()> |
e8693f1b |
382 | method in a subclass). |
8cd017a8 |
383 | |
384 | package MyApp; |
f5b61ad7 |
385 | |
8cd017a8 |
386 | use strict; |
387 | use Catalyst; |
f5b61ad7 |
388 | |
8cd017a8 |
389 | MyApp->config({ |
390 | name => 'MyApp', |
7d8aa5ec |
391 | root => MyApp->path_to('root'), |
6229ce0d |
392 | 'View::TT' => { |
7d8aa5ec |
393 | INCLUDE_PATH => [ |
394 | MyApp->path_to( 'root', 'templates', 'lib' ), |
395 | MyApp->path_to( 'root', 'templates', 'src' ), |
396 | ], |
8cd017a8 |
397 | PRE_PROCESS => 'config/main', |
398 | WRAPPER => 'site/wrapper', |
399 | }, |
400 | }); |
401 | |
402 | Note that any configuration items defined by one of the earlier |
403 | methods will be overwritten by items of the same name provided by the |
f5b61ad7 |
404 | latter methods. |
8cd017a8 |
405 | |
e2bbd784 |
406 | =head2 DYNAMIC INCLUDE_PATH |
407 | |
f7dfca06 |
408 | Sometimes it is desirable to modify INCLUDE_PATH for your templates at run time. |
f5b61ad7 |
409 | |
f7dfca06 |
410 | Additional paths can be added to the start of INCLUDE_PATH via the stash as |
411 | follows: |
412 | |
413 | $c->stash->{additional_template_paths} = |
414 | [$c->config->{root} . '/test_include_path']; |
415 | |
416 | If you need to add paths to the end of INCLUDE_PATH, there is also an |
417 | include_path() accessor available: |
418 | |
419 | push( @{ $c->view('TT')->include_path }, qw/path/ ); |
420 | |
421 | Note that if you use include_path() to add extra paths to INCLUDE_PATH, you |
422 | MUST check for duplicate paths. Without such checking, the above code will add |
423 | "path" to INCLUDE_PATH at every request, causing a memory leak. |
424 | |
425 | A safer approach is to use include_path() to overwrite the array of paths |
426 | rather than adding to it. This eliminates both the need to perform duplicate |
427 | checking and the chance of a memory leak: |
e2bbd784 |
428 | |
f7dfca06 |
429 | @{ $c->view('TT')->include_path } = qw/path another_path/; |
e2bbd784 |
430 | |
f5b61ad7 |
431 | If you are calling C<render> directly then you can specify dynamic paths by |
9d574573 |
432 | having a C<additional_template_paths> key with a value of additonal directories |
1bc9fc55 |
433 | to search. See L<CAPTURING TEMPLATE OUTPUT> for an example showing this. |
434 | |
8cd017a8 |
435 | =head2 RENDERING VIEWS |
436 | |
437 | The view plugin renders the template specified in the C<template> |
f5b61ad7 |
438 | item in the stash. |
8cd017a8 |
439 | |
440 | sub message : Global { |
94b3529a |
441 | my ( $self, $c ) = @_; |
442 | $c->stash->{template} = 'message.tt2'; |
6229ce0d |
443 | $c->forward( $c->view('TT') ); |
8cd017a8 |
444 | } |
722fede4 |
445 | |
c969f23a |
446 | If a stash item isn't defined, then it instead uses the |
447 | stringification of the action dispatched to (as defined by $c->action) |
448 | in the above example, this would be C<message>, but because the default |
449 | is to append '.tt', it would load C<root/message.tt>. |
8cd017a8 |
450 | |
451 | The items defined in the stash are passed to the Template Toolkit for |
452 | use as template variables. |
453 | |
8cd017a8 |
454 | sub default : Private { |

460 | |
8cd017a8 |
461 | A number of other template variables are also added: |
8077080c |
462 | |
8cd017a8 |
463 | c A reference to the context object, $c |
464 | base The URL base, from $c->req->base() |
465 | name The application name, from $c->config->{ name } |
466 | |
467 | These can be accessed from the template in the usual way: |
468 | |
469 | <message.tt2>: |
470 | |
471 | The message is: [% message %] |
472 | The base is [% base %] |
473 | The name is [% name %] |
474 | |
8cd017a8 |
475 | |

476 | The output generated by the template is stored in C<< $c->response->body >>. |
477 | |
478 | =head2 CAPTURING TEMPLATE OUTPUT |
479 | |
480 | If you wish to use the output of a template for some other purpose than |
481 | displaying in the response, e.g. for sending an email, this is possible using |
482 | L<Catalyst::Plugin::Email> and the L<render> method: |
483 | |
484 | sub send_email : Local { |
485 | my ($self, $c) = @_; |
f5b61ad7 |
486 | |
1bc9fc55 |
487 | $c->email( |
488 | header => [ |
489 | To => 'me@localhost', |
490 | Subject => 'A TT Email', |
491 | ], |
492 | body => $c->view('TT')->render($c, 'email.tt', { |
9d574573 |
493 | additional_template_paths => [ $c->config->{root} . '/email_templates'], |
1bc9fc55 |
494 | email_tmpl_param1 => 'foo' |
495 | } |
496 | ), |
497 | ); |
498 | # Redirect or display a message |
499 | } |

505 | =head2 METHODS |
8077080c |
506 | |
b63ddd04 |
507 | =head2 new |
2774dc77 |
508 | |
f5b61ad7 |
509 | The constructor for the TT view. Sets up the template provider, |
2774dc77 |
510 | and reads the application config. |
511 | |
81b7f2a2 |
512 | =head2 process($c) |
8077080c |
513 | |
1bc9fc55 |
514 | Renders the template specified in C<< $c->stash->{template} >> or |
ad50568f |
515 | C<< $c->action >> (the private name of the matched action). Calls L<render> to |
1bc9fc55 |
516 | perform actual rendering. Output is stored in C<< $c->response->body >>. |
8077080c |
517 | |
81b7f2a2 |
518 | It is possible to forward to the process method of a TT view from inside |
519 | Catalyst like this: |
520 | |
521 | $c->forward('View::TT'); |
522 | |
523 | N.B. This is usually done automatically by L<Catalyst::Action::RenderView>. |
f2ee4d6c |
524 | |
b63ddd04 |
525 | =head2 render($c, $template, \%args) |
1bc9fc55 |
526 | |
cad820fe |
527 | Renders the given template and returns output. Throws a L<Template::Exception> |
f5b61ad7 |
528 | object upon error. |
1bc9fc55 |
529 | |
f5b61ad7 |
530 | The template variables are set to C<%$args> if $args is a hashref, or |
531 | $C<< $c->stash >> otherwise. In either case the variables are augmented with |
1bc9fc55 |
532 | C<base> set to C< << $c->req->base >>, C<c> to C<$c> and C<name> to |
533 | C<< $c->config->{name} >>. Alternately, the C<CATALYST_VAR> configuration item |
534 | can be defined to specify the name of a template variable through which the |
535 | context reference (C<$c>) can be accessed. In this case, the C<c>, C<base> and |
536 | C<name> variables are omitted. |
537 | |
f5b61ad7 |
538 | C<$template> can be anything that Template::process understands how to |
1bc9fc55 |
539 | process, including the name of a template file or a reference to a test string. |
540 | See L<Template::process|Template/process> for a full list of supported formats. |
541 | |
f59953e1 |
542 | To use the render method outside of your Catalyst app, just pass a undef context. |
cbb149dc |
543 | This can be useful for tests, for instance. |
544 | |
81b7f2a2 |
545 | It is possible to forward to the render method of a TT view from inside Catalyst |
546 | to render page fragments like this: |
547 | |
548 | my $fragment = $c->forward("View::TT", "render", $template_name, $c->stash->{fragment_data}); |
f2ee4d6c |
549 | |
b63ddd04 |
550 | =head2 template_vars |
850ee226 |
551 | |
1bc9fc55 |
552 | Returns a list of keys/values to be used as the catalyst variables in the |
850ee226 |
553 | template. |
554 | |
b63ddd04 |
555 | =head2 config |
8077080c |
556 | |
8cd017a8 |
557 | This method allows your view subclass to pass additional settings to |
4729c102 |
558 | the TT configuration hash, or to set the options as below: |
559 | |
b63ddd04 |
560 | =head2 paths |
561 | |
562 | The list of paths TT will look for templates in. |
4729c102 |
563 | |
f5b61ad7 |
564 | =head2 C<CATALYST_VAR> |
4729c102 |
565 | |
566 | Allows you to change the name of the Catalyst context object. If set, it will also |
567 | remove the base and name aliases, so you will have access them through <context>. |
568 | |
569 | For example: |
570 | |
571 | MyApp->config({ |
572 | name => 'MyApp', |
7d8aa5ec |
573 | root => MyApp->path_to('root'), |
6229ce0d |
574 | 'View::TT' => { |
4729c102 |
575 | CATALYST_VAR => 'Catalyst', |
576 | }, |
577 | }); |
578 | |
579 | F<message.tt2>: |
580 | |
581 | The base is [% Catalyst.req.base %] |
582 | The name is [% Catalyst.config.name %] |
583 | |
b63ddd04 |
584 | =head2 C<TIMER> |
4729c102 |
585 | |
586 | If you have configured Catalyst for debug output, and turned on the TIMER setting, |
587 | C<Catalyst::View::TT> will enable profiling of template processing |
588 | (using L<Template::Timer>). This will embed HTML comments in the |
589 | output from your templates, such as: |
590 | |
591 | <!-- TIMER START: process mainmenu/mainmenu.ttml --> |
592 | <!-- TIMER START: include mainmenu/cssindex.tt --> |
593 | <!-- TIMER START: process mainmenu/cssindex.tt --> |
594 | <!-- TIMER END: process mainmenu/cssindex.tt (0.017279 seconds) --> |
595 | <!-- TIMER END: include mainmenu/cssindex.tt (0.017401 seconds) --> |
596 | |
597 | .... |
598 | |
599 | <!-- TIMER END: process mainmenu/footer.tt (0.003016 seconds) --> |
600 | |
601 | |
b63ddd04 |
602 | =head2 C<TEMPLATE_EXTENSION> |
4729c102 |
603 | |
747f2b6d |
604 | a sufix to add when looking for templates bases on the C<match> method in L<Catalyst::Request>. |
4729c102 |
605 | |
606 | For example: |
607 | |
6229ce0d |
608 | package MyApp::Controller::Test; |
f5b61ad7 |
609 | sub test : Local { .. } |
4729c102 |
610 | |
611 | Would by default look for a template in <root>/test/test. If you set TEMPLATE_EXTENSION to '.tt', it will look for |
612 | <root>/test/test.tt. |
613 | |
51199593 |
614 | =head2 C<PROVIDERS> |
615 | |
616 | Allows you to specify the template providers that TT will use. |
617 | |
618 | MyApp->config({ |
619 | name => 'MyApp', |
620 | root => MyApp->path_to('root'), |
6229ce0d |
621 | 'View::TT' => { |
51199593 |
622 | PROVIDERS => [ |
623 | { |
624 | name => 'DBI', |
625 | args => { |
626 | DBI_DSN => 'dbi:DB2:books', |
627 | DBI_USER=> 'foo' |
628 | } |
629 | }, { |
630 | name => '_file_', |
631 | args => {} |
632 | } |
633 | ] |
634 | }, |
635 | }); |
636 | |
637 | The 'name' key should correspond to the class name of the provider you |
638 | want to use. The _file_ name is a special case that represents the default |
639 | TT file-based provider. By default the name is will be prefixed with |
640 | 'Template::Provider::'. You can fully qualify the name by using a unary |
641 | plus: |
642 | |
643 | name => '+MyApp::Provider::Foo' |
644 | |
6175bba7 |
645 | You can also specify the 'copy_config' key as an arrayref, to copy those keys |
646 | from the general config, into the config for the provider: |
f5b61ad7 |
647 | |
6175bba7 |
648 | DEFAULT_ENCODING => 'utf-8', |
649 | PROVIDERS => [ |
650 | { |
651 | name => 'Encoding', |
652 | copy_config => [qw(DEFAULT_ENCODING INCLUDE_PATH)] |
653 | } |
654 | ] |
f5b61ad7 |
655 | |
6175bba7 |
656 | This can prove useful when you want to use the additional_template_paths hack |
657 | in your own provider, or if you need to use Template::Provider::Encoding |
658 | |
8cd017a8 |
659 | =head2 HELPERS |
660 | |
661 | The L<Catalyst::Helper::View::TT> and |
662 | L<Catalyst::Helper::View::TTSite> helper modules are provided to create |
663 | your view module. There are invoked by the F<myapp_create.pl> script: |
664 | |
665 | $ script/myapp_create.pl view TT TT |
666 | |
667 | $ script/myapp_create.pl view TT TTSite |
668 | |
669 | The L<Catalyst::Helper::View::TT> module creates a basic TT view |
670 | module. The L<Catalyst::Helper::View::TTSite> module goes a little |
671 | further. It also creates a default set of templates to get you |
672 | started. It also configures the view module to locate the templates |
673 | automatically. |
674 | |
02c64502 |
675 | =head1 NOTES |
676 | |
677 | If you are using the L<CGI> module inside your templates, you will |
678 | experience that the Catalyst server appears to hang while rendering |
679 | the web page. This is due to the debug mode of L<CGI> (which is |
680 | waiting for input in the terminal window). Turning off the |
681 | debug mode using the "-no_debug" option solves the |
682 | problem, eg.: |
683 | |
684 | [% USE CGI('-no_debug') %] |
