57 | =head1 DESCRIPTION |
58 | |
ffeb7448 |
59 | This tutorial provides a multi-part introduction to the Catalyst web |
d442cc9f |
60 | framework. It seeks to provide a rapid overview of many of its most |
61 | commonly used features. The focus is on the real-world best practices |
62 | required in the construction of nearly all Catalyst applications. |
63 | |
64 | Although the primary target of the tutorial is users new to the Catalyst |
65 | framework, experienced users may wish to review specific sections (for |
1def4a20 |
66 | example, how to use DBIC for their model classes, how to add |
67 | authentication and authorization to an existing application, or form |
68 | management). |
d442cc9f |
69 | |
70 | You can obtain the code for all the tutorial examples from the |
71 | catalyst subversion repository by issuing the command: |
72 | |
028b4e1a |
73 | svn co http://dev.catalyst.perl.org/repos/Catalyst/trunk/examples/Tutorial/ CatalystTutorial |
d442cc9f |
74 | |
75b13da6 |
75 | This will download the most recent code for each chapter of the |
76 | tutorial into the CatalystTutorial directory on your machine. |
d442cc9f |
77 | |
3d9ae335 |
78 | B<These reference implementations are provided so that when you follow |
79 | the tutorial, you can use the code from the subversion repository to |
80 | ensure that your system is set up correctly, and that you have not |
81 | inadvertently made any typographic errors, or accidentally skipped |
82 | part of the tutorial.> |
83 | |
ffeb7448 |
84 | B<NOTE: You can use any Perl-supported OS and environment to run |
3533daff |
85 | Catalyst.> It should make little or no difference to Catalyst's |
acbd7bdd |
86 | operation, B<but this tutorial has been written using the Debian 5 |
3f043f41 |
87 | live CD> because that represents a quick and easy way for most people to |
acbd7bdd |
88 | try out Catalyst with virtually zero setup time and hassles. Also, |
89 | the tutorial has been tested to work correctly with the versions of |
90 | Catalyst and all the supporting modules in Debian 5 (see "VERSIONS |
91 | AND CONVENTIONS USED IN THIS TUTORIAL" below for the specific versions |
92 | for some of the key modules), so B<if you think you might be running |
93 | into an issue related to versions> (for example, a module changed its |
94 | behavior in a newer version or a bug was introduced), B<it might be |
444d6b27 |
95 | worth giving Debian 5 a try>. |
3533daff |
96 | |
444d6b27 |
97 | If you plan to follow along with Debian 5, you can jump down to the |
98 | "Debian" section under L</"CATALYST INSTALLATION"> below and it will walk you |
99 | though the setup of a fully functional Catalyst environment. If you |
100 | would prefer to install directly from CPAN, you can download the example |
3533daff |
101 | program and all the necessary dependencies to your local machine by |
444d6b27 |
102 | installing the C<Task::Catalyst::Tutorial> distribution: |
d442cc9f |
103 | |
104 | cpan Task::Catalyst::Tutorial |
105 | |
106 | This will also test to make sure the dependencies are working. If you |
107 | have trouble installing these, please ask for help on the #catalyst |
108 | IRC channel, or the Catalyst mailing list. |

170 | This tutorial makes the learning process its main priority. For |
171 | example, the level of comments in the code found here would likely be |
1def4a20 |
172 | considered excessive in a "normal project." Because of their contextual |
d442cc9f |
173 | value, this tutorial will generally favor inline comments over a |
174 | separate discussion in the text. It also deliberately tries to |
175 | demonstrate multiple approaches to various features (in general, you |
176 | should try to be as consistent as possible with your own production |
177 | code). |
178 | |
179 | Furthermore, this tutorial tries to minimize the number of controllers, |
180 | models, TT templates, and database tables. Although this does result in |
181 | things being a bit contrived at times, the concepts should be applicable |
182 | to more complex environments. More complete and complicated example |
183 | applications can be found in the C<examples> area of the Catalyst |
184 | Subversion repository at |
185 | L<http://dev.catalyst.perl.org/repos/Catalyst/trunk/examples/>. |

280 | This tutorial will assume that the web browser is located on the same |
281 | system where the Catalyst development server is running, and |
282 | therefore use a URL of C<http://localhost:3000> (the Catalyst |
283 | development server defaults to port 3000). If you are running Perl on |
284 | a different box than where your web browser is located (or using a |
285 | different port number via the C<-p> I<port_number> option to the |
286 | development server), then you will need to update the URL you use |
287 | accordingly. |
288 | |
289 | Please Note: Depending on the web browser you are using, you might |
290 | need to hit C<Shift+Reload> or C<Ctrl+Reload> to pull a fresh page |
291 | when testing your application at various points (see |
292 | L<http://en.wikipedia.org/wiki/Bypass_your_cache> for a comprehensive |
1390ef0e |
293 | list of options for each browser). Also, the C<-k> keepalive option |
294 | to the development server can be necessary with some browsers |
295 | (especially Internet Explorer). |

300 | =head1 CATALYST INSTALLATION |
301 | |
acbd7bdd |
302 | Although Catalyst installation has been a challenge in the past, the |
303 | good news is that there are a growing number of options to eliminate |
304 | (or at least dramatically simplify) this concern. Although a |
305 | compelling strength of Catalyst is that it makes use of many of the |
306 | modules in the vast repository that is CPAN, this can complicate the |
307 | installation process if you approach it in the wrong way. Consider |
308 | the following suggestions on the most common ways to get started with |
309 | a Catalyst development environment: |

315 | Debian |
316 | |
317 | The Debian 5 live CD represents a great way for newcomers to |
318 | experiment with Catalyst. As a "live CD," you can simple boot from |
319 | the CD, run a few commands, and in a matter of minutes you should have |
320 | a fully function environment in which do this tutorial. B<The tutorial |
321 | was fully tested to work under Debian 5. Although it SHOULD work |
322 | under any Catalyst installation method you might choose, it can be |
323 | hard to guarantee this.> |

329 | Download one of the ISO files from |
6163536a |
330 | L<http://cdimage.debian.org/cdimage/release/current-live/i386/iso-cd/> |
331 | (the current version at the time this was written was 5.0.3). |
acbd7bdd |
332 | You can pick any one of the live CD variations will work, but |
333 | you may wish to consider the following points: |
334 | |

337 | =item * |
338 | |
6163536a |
339 | "C<debian-live-503-i386-rescue.iso>" is probably the best all-around |
acbd7bdd |
340 | option for most people because it includes many extra tools such as |
341 | the GCC compiler, therefore saving RAM (every package you need to |
342 | install when running from live CD consumes memory because RAM disk is |
343 | being used in lieu of real disk space). When initially booting under |
344 | this image, you may see some cryptic warning messages having to do |
345 | with various diagnostic tools it tries to load or enable, but you |
346 | should be able to safely ignore these. |
347 | |
348 | =item * |
349 | |
6163536a |
350 | "C<debian-live-503-i386-standard.iso>" is a great option because of |
acbd7bdd |
351 | its compact size, but you will probably need approximately 1 GB of RAM |
352 | in the computer where you will run the tutorial. Because the |
353 | "standard" live CD comes with with a minimal set of tools, we will |
354 | have to install extra packages (such as the GCC compiler), all of |
355 | which will require RAM when running from a live CD. |
356 | |
357 | =item * |
358 | |
359 | The other ISO images include different flavors of X-Windows desktop |
360 | managers. You can select one of these if you don't mind the larger |
361 | download size and prefer a graphical environment. Be aware that these |
362 | disks do not come with the extra tools found on the "rescue" image, so |
363 | you will need adequate RAM to be able to install them just as you |
364 | would under the "standard" image. B<Use one of the "graphical" ISO |
365 | images if you want a graphical web browser on the same machine as |
366 | where you will run the tutorial.> (If you are using one of the non- |
367 | graphical images discussed above, you can still use a graphical web |
368 | browser from another machine and point it to your Catalyst development |
369 | machine.) |

375 | Boot off the CD. |

379 | Select "C<Live>" from the initial boot menu. |

381 | =item * |
382 | |
6163536a |
383 | Once the system has booted to a "C<user@debian:~$>" prompt, first |
384 | install the Subversion client in case you want to check out the |
385 | completed chapter example code: |
386 | |
387 | sudo aptitude -y install subversion |
388 | |
389 | Then enter the following command to add the more current "unstable" |
390 | package repository so we get the latest versions of Catalyst and |
391 | related packages: |
acbd7bdd |
392 | |
393 | sudo vi /etc/apt/sources.list |
394 | |
395 | Add the following line to the bottom of this file: |
396 | |
397 | deb http://ftp.us.debian.org/debian/ unstable main |
398 | |
399 | If you are not familiar with VI, you can move to the bottom of this |
400 | file and press the "o" key to insert a new line and type the line |
401 | above. Then press the "Esc" key followed by a colon (":"), the |
402 | letters "wq" and then the "Enter" key. The rest of the tutorial will |
403 | assume that you know how to use some editor that is available from the |
404 | Linux command-line environment. |
405 | |
406 | =item * |
407 | |
408 | Install Catalyst: |
409 | |
410 | sudo aptitude update |
411 | sudo aptitude -y install sqlite3 libdbd-sqlite3-perl libcatalyst-perl \ |
444d6b27 |
412 | libcatalyst-modules-perl libdbix-class-timestamp-perl \ |
2314f851 |
413 | libdatetime-format-sqlite-perl libconfig-general-perl \ |
6163536a |
414 | libhtml-formfu-model-dbic-perl libterm-readline-perl-perl |
444d6b27 |
415 | |
416 | Let it install (normally about a 30 to 90-second operaton) and you are |
417 | done. (Note the '\' above. Depending on your environment, you might |
418 | be able to cut and paste the text as shown or need to remove the '\' |
fce83e5f |
419 | characters to that the command is all on a single line.) |
acbd7bdd |
420 | |
421 | If you are using an image other than the "rescue" ISO, you will also need |
422 | to run the following command to install additional packages: |
423 | |
424 | sudo aptitude -y install gcc make libc6-dev |
425 | |
426 | If you are running from the Live CD, you probably also want to free up |
427 | some RAM disk space with the following: |
428 | |
429 | sudo aptitude clean |
430 | |
431 | NOTE: While the instructions above mention the Live CD because that |
432 | makes it easy for people new to Linux, you can obviously pick a |
433 | different Debian ISO image and install it to your hard drive. |
434 | Although there are many different ways to download and install Debian, |
435 | the "netinst" ISO image (such as "C<debian-500-i386-netinst.iso>" |
436 | represents a great option because it keeps your initial download small |
437 | (but still let's you install anything you want "over the network"). |
438 | |
439 | Here are some tips if you are running from a live CD and are running |
440 | out of disk space (which really means you are running out of RAM): |
441 | |
442 | =over 4 |
443 | |
444 | =item * |
445 | |
446 | Always run "C<aptitude clean>" after you install new packages to |
447 | delete the original .deb files (the files installed B<by> the .deb |
448 | package B<will> remain available, just the .deb package itself is |
449 | deleted). |
450 | |
451 | =item * |
452 | |
453 | If you are installing modules from CPAN, you can free up some space |
444d6b27 |
454 | with "C<rm -rf /root/.cpan/*>" (change "/root/" in the previous |
455 | command to match your home directory or the location where CPAN |
456 | has been configured to perform build operations). |
acbd7bdd |
457 | |
458 | =item * |
459 | |
460 | If necessary, you can remove the cached package information with the |
461 | command "C<rm -f /var/lib/apt/lists/*>". You can later pull this |
462 | information again via the command "C<aptitude update>". |
463 | |
464 | =item * |
465 | |
466 | You can save a small amount of space by commenting out the lines in |
467 | C</etc/apt/sources.list> that reference "deb-src" and |
468 | "security.debian.org". If you have already done an "C<aptitude |
469 | update>" with these repositories enabled, you can use the tip in the |
470 | previous bullet to free the space up (and then do another "C<aptitude |
471 | update>"). |
472 | |
473 | =item * |
474 | |
475 | Although you can free up space by removing packages you installed |
476 | since you last booted (check out "C<aptitude remove _pkg_name>"), |
477 | don't bother trying to remove packages already available at the time |
478 | of boot. Instead of freeing up space, it will actual I<consume> some |
479 | space. (The live CD uses these "burn in" packages right from the CD |
480 | disk vs. first loading them on the virtual RAM disk. However, if you |
481 | remove them, the system has to update various files, something that |
482 | I<does> consume some space on the virtual RAM disk.) |

490 | Ubuntu |
491 | |
acbd7bdd |
492 | Ubuntu is an extremely popular offshoot of Debian. It provides |
493 | cutting edge versions of many common tools, application and libraries |
494 | in an easy-to-run live CD configuration (and because a single download |
495 | option can be used for both live CD and install-to-disk usage, it |
496 | keeps your download options nice and simple). As with Debian 5, you |
497 | should be able to generate a fully function Catalyst environment in a |
498 | matter of minutes. Here are quick instructions on how to use Ubuntu |
499 | to prepare for the tutorial: |

505 | Download the Ubuntu Desktop edition and boot from the CD and/or image |
506 | file, select your language, and then "Try Ubuntu without any changes |
507 | to your computer." |

516 | Add the 'universe' repositories: |
517 | |
3533daff |
518 | sudo gedit /etc/apt/sources.list |
1def4a20 |
519 | |
520 | And remove the comments from the lines under the comments about the |
521 | 'universe' repositories. |
522 | |
523 | =item * |
524 | |
525 | Install Catalyst: |
526 | |
acbd7bdd |
527 | sudo aptitude update |
528 | sudo aptitude install libdbd-sqlite3-perl libcatalyst-perl libcatalyst-modules-perl libconfig-general-perl |
1def4a20 |
529 | |

530 | Accept all of the dependencies. Done. |
531 | |
532 | If you are running from the Live CD, you probably also want to free up |
533 | some disk space with the following: |
534 | |
acbd7bdd |
535 | sudo aptitude clean |
2b75577c |
536 | |
acbd7bdd |
537 | NOTE: While the instructions above mention the live CD because that |
2b75577c |
538 | makes it easy for people new to Linux, you can obviously also use one |
539 | of the options to install Ubuntu on your drive. |

547 | Available at L<http://www.shadowcat.co.uk/static/cat-install>, |

548 | C<cat-install> can be a fairly painless way to get Catalyst up and |
549 | running. Just download the script from the link above and type C<perl |
550 | cat-install>. Depending on the speed of your Internet connection and |
551 | your computer, it will probably take 30 to 60 minutes to install because |
552 | it downloads, makes, compiles, and tests every module. But this is an |
553 | excellent way to automate the installation of all the latest modules |
554 | used by Catalyst from CPAN. |

607 | |
608 | This tutorial will primarily focus on SQLite because of its simplicity |
609 | of installation and use; however, modifications in the script required |
acbd7bdd |
610 | to support MySQL and PostgreSQL will be presented in Appendix. |
d442cc9f |
611 | |
612 | B<Note:> One of the advantages of the MVC design patterns is that |
613 | applications become much more database independent. As such, you will |
614 | notice that only the C<.sql> files used to initialize the database |
615 | change between database systems: the Catalyst code generally remains the |
616 | same. |

620 | |
4b4d3884 |
621 | Each chapter of the tutorial has complete code available as a tarball in |
028b4e1a |
622 | the main Catalyst Subversion repository (see the note at the beginning |
623 | of each part for the appropriate svn command to use). |
d442cc9f |
624 | |
4b4d3884 |
625 | B<NOTE:> You can run the test cases for the final code through Chapter 8 |
028b4e1a |
626 | with the following commands: |
d442cc9f |
627 | |
6163536a |
628 | svn co http://dev.catalystframework.org/repos/Catalyst/trunk/examples/Tutorial/MyApp_Chapter8 |
629 | cd MyApp_Chapter8/MyApp |
96a87356 |
630 | CATALYST_DEBUG=0 prove -wl t |
d442cc9f |
631 | |
96a87356 |
632 | If you wish to include the L<HTML::FormFu|HTML::FormFu> section in your tests, |
6163536a |
633 | substitute C<MyApp_Chapter9_FormFu> for C<MyApp_Chapter8> in the URL |
634 | above (don't forget to "cd" out of the Ch8 directory if you ran the code above). |
acbd7bdd |
635 | |
6163536a |
636 | svn co http://dev.catalystframework.org/repos/Catalyst/trunk/examples/Tutorial/MyApp_Chapter9_FormFu |
637 | cd MyApp_Chapter9_FormFu/MyApp |
96a87356 |
638 | CATALYST_DEBUG=0 prove -wl t |
acbd7bdd |
639 | |
640 | You can also fire up the application under the development server that is conveniently |
641 | built in to Catalyst. Just issue this command from the C<MyApp> directory where you |
642 | ran the test suite above: |
643 | |
644 | script/myapp_server.pl |
645 | |
646 | And the application will start. You can try out the application by |
647 | pulling up C<http://localhost:3000> in your web browser (as mentioned |
648 | earlier, change C<localhost> to a different IP address or DNS name if |
649 | you are running your web browser and your Catalyst development on |
650 | different boxes). We will obviously see more about how to use the |
4b4d3884 |
651 | application as we go through the remaining chapters of the tutorial, but |
acbd7bdd |
652 | for now you can log in using the username "test01" and a password of |
653 | "mypass". |
