171 | =head1 DESCRIPTION |
172 | |
fc7ec1d9 |
173 | The key concept of Catalyst is DRY (Don't Repeat Yourself). |
174 | |
175 | See L<Catalyst::Manual> for more documentation. |
176 | |
ae1e6b59 |
177 | Catalyst plugins can be loaded by naming them as arguments to the "use |
178 | Catalyst" statement. Omit the C<Catalyst::Plugin::> prefix from the |
179 | plugin name, i.e., C<Catalyst::Plugin::My::Module> becomes |
180 | C<My::Module>. |
fc7ec1d9 |
181 | |
0ef52a96 |
182 | use Catalyst qw/My::Module/; |
fc7ec1d9 |
183 | |
836e1134 |
184 | If your plugin starts with a name other than C<Catalyst::Plugin::>, you can |
185 | fully qualify the name by using a unary plus: |
186 | |
187 | use Catalyst qw/ |
188 | My::Module |
189 | +Fully::Qualified::Plugin::Name |
190 | /; |
191 | |
ae1e6b59 |
192 | Special flags like C<-Debug> and C<-Engine> can also be specified as |
193 | arguments when Catalyst is loaded: |
fc7ec1d9 |
194 | |
195 | use Catalyst qw/-Debug My::Module/; |
196 | |
ae1e6b59 |
197 | The position of plugins and flags in the chain is important, because |
198 | they are loaded in exactly the order in which they appear. |
fc7ec1d9 |
199 | |
23f9d934 |
200 | The following flags are supported: |
201 | |
b5ecfcf0 |
202 | =head2 -Debug |
23f9d934 |
203 | |
0ef52a96 |
204 | Enables debug output. |
fc7ec1d9 |
205 | |
b5ecfcf0 |
206 | =head2 -Engine |
fc7ec1d9 |
207 | |
ae1e6b59 |
208 | Forces Catalyst to use a specific engine. Omit the |
209 | C<Catalyst::Engine::> prefix of the engine name, i.e.: |
fc7ec1d9 |
210 | |
0ef52a96 |
211 | use Catalyst qw/-Engine=CGI/; |
fc7ec1d9 |
212 | |
b5ecfcf0 |
213 | =head2 -Home |
fbcc39ad |
214 | |
ae1e6b59 |
215 | Forces Catalyst to use a specific home directory, e.g.: |
216 | |
217 | use Catalyst qw[-Home=/usr/sri]; |
fbcc39ad |
218 | |
b5ecfcf0 |
219 | =head2 -Log |
fbcc39ad |
220 | |
0ef52a96 |
221 | Specifies log level. |

223 | =head1 METHODS |
224 | |
f7b672ef |
225 | =head2 INFORMATION ABOUT THE CURRENT REQUEST |
0ef52a96 |
226 | |
b5ecfcf0 |
227 | =head2 $c->action |
66e28e3f |
228 | |
ae1e6b59 |
229 | Returns a L<Catalyst::Action> object for the current action, which |
230 | stringifies to the action name. See L<Catalyst::Action>. |
0ef52a96 |
231 | |
b5ecfcf0 |
232 | =head2 $c->namespace |
0ef52a96 |
233 | |
ae1e6b59 |
234 | Returns the namespace of the current action, i.e., the uri prefix |
235 | corresponding to the controller of the current action. For example: |
236 | |
237 | # in Controller::Foo::Bar |
238 | $c->namespace; # returns 'foo/bar'; |
0ef52a96 |
239 | |
b5ecfcf0 |
240 | =head2 $c->request |
0ef52a96 |
241 | |
b5ecfcf0 |
242 | =head2 $c->req |
0ef52a96 |
243 | |
ae1e6b59 |
244 | Returns the current L<Catalyst::Request> object. See |
245 | L<Catalyst::Request>. |
0ef52a96 |
246 | |
f7b672ef |
247 | =head2 PROCESSING AND RESPONSE TO THE CURRENT REQUEST |
0ef52a96 |
248 | |
b5ecfcf0 |
249 | =head2 $c->forward( $action [, \@arguments ] ) |
0ef52a96 |
250 | |
b5ecfcf0 |
251 | =head2 $c->forward( $class, $method, [, \@arguments ] ) |
0ef52a96 |
252 | |
ae1e6b59 |
253 | Forwards processing to a private action. If you give a class name but no |
254 | method, C<process()> is called. You may also optionally pass arguments |
255 | in an arrayref. The action will receive the arguments in C<@_> and |
256 | C<$c-E<gt>req-E<gt>args>. Upon returning from the function, |
257 | C<$c-E<gt>req-E<gt>args> will be restored to the previous values. |
0ef52a96 |
258 | |
3b984c64 |
259 | Any data C<return>ed from the action forwarded to, will be returned by the |
d759db1e |
260 | call to forward. |
3b984c64 |
261 | |
262 | my $foodata = $c->forward('/foo'); |
0ef52a96 |
263 | $c->forward('index'); |
e112461a |
264 | $c->forward(qw/MyApp::Model::DBIC::Foo do_stuff/); |
0ef52a96 |
265 | $c->forward('MyApp::View::TT'); |
266 | |
267 | =cut |
268 | |
269 | sub forward { my $c = shift; $c->dispatcher->forward( $c, @_ ) } |
270 | |
b5ecfcf0 |
271 | =head2 $c->detach( $action [, \@arguments ] ) |
0ef52a96 |
272 | |
b5ecfcf0 |
273 | =head2 $c->detach( $class, $method, [, \@arguments ] ) |
0ef52a96 |
274 | |
275 | The same as C<forward>, but doesn't return. |
276 | |
277 | =cut |
278 | |
279 | sub detach { my $c = shift; $c->dispatcher->detach( $c, @_ ) } |
280 | |
b5ecfcf0 |
281 | =head2 $c->error |
0ef52a96 |
282 | |
b5ecfcf0 |
283 | =head2 $c->error($error, ...) |
0ef52a96 |
284 | |
b5ecfcf0 |
285 | =head2 $c->error($arrayref) |
0ef52a96 |
286 | |
83a8fcac |
287 | Returns an arrayref containing error messages. If Catalyst encounters an |
288 | error while processing a request, it stores the error in $c->error. This |
289 | method should not be used to store non-fatal error messages. |
0ef52a96 |
290 | |
291 | my @error = @{ $c->error }; |
292 | |
293 | Add a new error. |
294 | |
295 | $c->error('Something bad happened'); |
296 | |
0ef52a96 |
297 | =cut |
298 | |
299 | sub error { |
300 | my $c = shift; |
301 | if ( $_[0] ) { |
302 | my $error = ref $_[0] eq 'ARRAY' ? $_[0] : [@_]; |
9ce44430 |

305 | } |
306 | elsif ( defined $_[0] ) { $c->{error} = undef } |
307 | return $c->{error} || []; |
308 | } |
309 | |
ca81eb67 |
310 | =head2 $c->clear_errors |
311 | |
312 | Clear errors. You probably don't want to clear the errors unless you are |
313 | implementing a custom error screen. |
314 | |
315 | This is equivalent to running |
316 | |
317 | $c->error(0); |
318 | |
319 | =cut |
320 | |
321 | sub clear_errors { |
322 | my $c = shift; |
323 | $c->error(0); |
324 | } |
325 | |
b5ecfcf0 |
326 | =head2 $c->response |
0ef52a96 |
327 | |
b5ecfcf0 |
328 | =head2 $c->res |
0ef52a96 |
329 | |
330 | Returns the current L<Catalyst::Response> object. |
331 | |
b5ecfcf0 |
332 | =head2 $c->stash |
0ef52a96 |
333 | |
ae1e6b59 |
334 | Returns a hashref to the stash, which may be used to store data and pass |
335 | it between components during a request. You can also set hash keys by |
336 | passing arguments. The stash is automatically sent to the view. The |
337 | stash is cleared at the end of a request; it cannot be used for |
338 | persistent storage. |
0ef52a96 |
339 | |
340 | $c->stash->{foo} = $bar; |
341 | $c->stash( { moose => 'majestic', qux => 0 } ); |
342 | $c->stash( bar => 1, gorch => 2 ); # equivalent to passing a hashref |
343 | |
344 | # stash is automatically passed to the view for use in a template |
345 | $c->forward( 'MyApp::V::TT' ); |
346 | |
347 | =cut |
348 | |
349 | sub stash { |
350 | my $c = shift; |
351 | if (@_) { |
352 | my $stash = @_ > 1 ? {@_} : $_[0]; |

358 | } |
359 | |
b5ecfcf0 |
360 | =head2 $c->state |
0ef52a96 |

973 | <p>Welcome to the wonderful world of Catalyst. |
f92fd545 |
974 | This <a href="http://en.wikipedia.org/wiki/MVC">MVC</a> |
975 | framework will make web development something you had |
60dd6e1d |
976 | never expected it to be: Fun, rewarding, and quick.</p> |
ab2374d3 |
977 | <h2>What to do now?</h2> |
4b8cb778 |
978 | <p>That really depends on what <b>you</b> want to do. |
ab2374d3 |
979 | We do, however, provide you with a few starting points.</p> |
980 | <p>If you want to jump right into web development with Catalyst |
5db7f9a1 |
981 | you might want to check out the documentation.</p> |

2114 | |
ae1e6b59 |
2115 | Catalyst uses internal actions like C<_DISPATCH>, C<_BEGIN>, C<_AUTO>, |
2116 | C<_ACTION>, and C<_END>. These are by default not shown in the private |
3e705254 |

d2ee9760 |
2121 | =head1 CASE SENSITIVITY |
2122 | |
3e705254 |
2123 | By default Catalyst is not case sensitive, so C<MyApp::C::FOO::Bar> is |
ae1e6b59 |
2124 | mapped to C</foo/bar>. You can activate case sensitivity with a config |
3e705254 |
2125 | parameter. |
d2ee9760 |
2126 | |
2127 | MyApp->config->{case_sensitive} = 1; |
2128 | |
3e705254 |
2129 | This causes C<MyApp::C::Foo::Bar> to map to C</Foo/Bar>. |

2131 | =head1 ON-DEMAND PARSER |
2132 | |
2133 | The request body is usually parsed at the beginning of a request, |
3e705254 |
2134 | but if you want to handle input yourself or speed things up a bit, |
fbcc39ad |
2135 | you can enable on-demand parsing with a config parameter. |
2136 | |
2137 | MyApp->config->{parse_on_demand} = 1; |
2138 | |
2139 | =head1 PROXY SUPPORT |
2140 | |
ae1e6b59 |
2141 | Many production servers operate using the common double-server approach, |
2142 | with a lightweight frontend web server passing requests to a larger |
2143 | backend server. An application running on the backend server must deal |
2144 | with two problems: the remote user always appears to be C<127.0.0.1> and |
2145 | the server's hostname will appear to be C<localhost> regardless of the |
2146 | virtual host that the user connected through. |
fbcc39ad |
2147 | |
ae1e6b59 |
2148 | Catalyst will automatically detect this situation when you are running |
2149 | the frontend and backend servers on the same machine. The following |
2150 | changes are made to the request. |
fbcc39ad |
2151 | |
ae1e6b59 |
2152 | $c->req->address is set to the user's real IP address, as read from |
2153 | the HTTP X-Forwarded-For header. |
fbcc39ad |
2154 | |
ae1e6b59 |
2155 | The host value for $c->req->base and $c->req->uri is set to the real |
2156 | host, as read from the HTTP X-Forwarded-Host header. |
fbcc39ad |
2157 | |
3e705254 |
2158 | Obviously, your web server must support these headers for this to work. |
fbcc39ad |
2159 | |
ae1e6b59 |
2160 | In a more complex server farm environment where you may have your |
2161 | frontend proxy server(s) on different machines, you will need to set a |

2171 | =head1 THREAD SAFETY |
2172 | |
2173 | Catalyst has been tested under Apache 2's threading mpm_worker, mpm_winnt, |
3e705254 |
2174 | and the standalone forking HTTP server on Windows. We believe the Catalyst |
fbcc39ad |
2175 | core to be thread-safe. |
2176 | |
2177 | If you plan to operate in a threaded environment, remember that all other |
3e705254 |
2178 | modules you are using must also be thread-safe. Some modules, most notably |
2179 | L<DBD::SQLite>, are not thread-safe. |
