101 | Catalyst::Controller - Catalyst Controller base class |
102 | |
103 | =head1 SYNOPSIS |
104 | |
234763d4 |
105 | package MyApp::Controller::Search |
a269e0c2 |
106 | use base qw/Catalyst::Controller/; |

5ee249f2 |
112 | |
113 | =head1 DESCRIPTION |
114 | |
a269e0c2 |
115 | Controllers are where the actions in the Catalyst framework |
116 | reside. Each action is represented by a function with an attribute to |
117 | identify what kind of action it is. See the L<Catalyst::Dispatcher> |
118 | for more info about how Catalyst dispatches to actions. |

611 | =head1 CONFIGURATION |
612 | |
a269e0c2 |
613 | Like any other L<Catalyst::Component>, controllers have a config hash, |
614 | accessible through $self->config from the controller actions. Some |
615 | settings are in use by the Catalyst framework: |
234763d4 |
616 | |
617 | =head2 namespace |
618 | |
a269e0c2 |
619 | This specifies the internal namespace the controller should be bound |
620 | to. By default the controller is bound to the URI version of the |
621 | controller name. For instance controller 'MyApp::Controller::Foo::Bar' |
622 | will be bound to 'foo/bar'. The default Root controller is an example |
623 | of setting namespace to '' (the null string). |
234763d4 |
624 | |
27ae4114 |
625 | =head2 path |
234763d4 |
626 | |
627 | Sets 'path_prefix', as described below. |
628 | |
0a2577a8 |
629 | =head2 action |
630 | |
631 | Allows you to set the attributes that the dispatcher creates actions out of. |
632 | This allows you to do 'rails style routes', or override some of the |
f4dda4a8 |
633 | attribute definitions of actions composed from Roles. |
0a2577a8 |
634 | You can set arguments globally (for all actions of the controller) and |
635 | specifically (for a single action). |
636 | |
637 | __PACKAGE__->config( |
638 | action => { |
639 | '*' => { Chained => 'base', Args => 0 }, |
640 | base => { Chained => '/', PathPart => '', CaptureArgs => 0 }, |
641 | }, |
642 | ); |
643 | |
644 | In the case above every sub in the package would be made into a Chain |
645 | endpoint with a URI the same as the sub name for each sub, chained |
646 | to the sub named C<base>. Ergo dispatch to C</example> would call the |
647 | C<base> method, then the C<example> method. |
648 | |
c8136648 |
649 | =head2 action_args |
650 | |
4d4e5de8 |
651 | Allows you to set constructor arguments on your actions. You can set arguments |
0a2577a8 |
652 | globally and specifically (as above). |
653 | This is particularly useful when using C<ActionRole>s |
b939ae6b |
654 | (L<Catalyst::Controller::ActionRole>) and custom C<ActionClass>es. |
c8136648 |
655 | |
b939ae6b |
656 | __PACKAGE__->config( |
c8136648 |
657 | action_args => { |
b939ae6b |
658 | '*' => { globalarg1 => 'hello', globalarg2 => 'goodbye' }, |
659 | 'specific_action' => { customarg => 'arg1' }, |
cea3f28a |
660 | }, |
b939ae6b |
661 | ); |
cea3f28a |
662 | |
b939ae6b |
663 | In the case above the action class associated with C<specific_action> would get |
664 | passed the following arguments, in addition to the normal action constructor |
665 | arguments, when it is instantiated: |
666 | |
667 | (globalarg1 => 'hello', globalarg2 => 'goodbye', customarg => 'arg1') |
c8136648 |

672 | |
c4d02967 |
673 | From L<Catalyst::Component::ApplicationAttribute>, stashes the application |
674 | instance as $self->_application. |
234763d4 |
675 | |
676 | =head2 $self->action_for('name') |
677 | |
a269e0c2 |

679 | in this component. |
234763d4 |
680 | |
234763d4 |
681 | =head2 $self->action_namespace($c) |
682 | |
a269e0c2 |
683 | Returns the private namespace for actions in this component. Defaults |
684 | to a value from the controller name (for |
685 | e.g. MyApp::Controller::Foo::Bar becomes "foo/bar") or can be |
686 | overridden from the "namespace" config key. |
234763d4 |
687 | |
688 | |
689 | =head2 $self->path_prefix($c) |
690 | |
4ba7161b |
691 | Returns the default path prefix for :PathPrefix, :Local and |
e5d2cfdb |
692 | relative :Path actions in this component. Defaults to the action_namespace or |
a269e0c2 |
693 | can be overridden from the "path" config key. |
234763d4 |
694 | |
c4d02967 |
695 | =head2 $self->register_actions($c) |
696 | |
697 | Finds all applicable actions for this component, creates |
698 | Catalyst::Action objects (using $self->create_action) for them and |
699 | registers them with $c->dispatcher. |
700 | |
701 | =head2 $self->get_action_methods() |
702 | |
703 | Returns a list of L<Moose::Meta::Method> objects, doing the |
704 | L<MooseX::MethodAttributes::Role::Meta::Method> role, which are the set of |
705 | action methods for this package. |
706 | |
707 | =head2 $self->register_action_methods($c, @methods) |
708 | |
709 | Creates action objects for a set of action methods using C< create_action >, |
710 | and registers them with the dispatcher. |
711 | |
f0a9b791 |
712 | =head2 $self->action_class(%args) |
713 | |
714 | Used when a controller is creating an action to determine the correct base |
24d2dfaf |
715 | action class to use. |
f0a9b791 |
716 | |
234763d4 |
717 | =head2 $self->create_action(%args) |
718 | |
a269e0c2 |
719 | Called with a hash of data to be use for construction of a new |
720 | Catalyst::Action (or appropriate sub/alternative class) object. |
234763d4 |
721 | |
eff60019 |
722 | =head2 $self->gather_action_roles(\%action_args) |
723 | |
724 | Gathers the list of roles to apply to an action with the given %action_args. |

727 | |
728 | returns a list of action roles to be applied based on core, builtin rules. |
729 | Currently only the L<Catalyst::ActionRole::HTTPMethods> role is applied |
730 | this way. |
731 | |
a269e0c2 |
732 | =head2 $self->_application |
234763d4 |
733 | |
734 | =head2 $self->_app |
735 | |

738 | =head1 ACTION SUBROUTINE ATTRIBUTES |
739 | |
740 | Please see L<Catalyst::Manual::Intro> for more details |
741 | |
742 | Think of action attributes as a sort of way to record metadata about an action, |
743 | similar to how annotations work in other languages you might have heard of. |
744 | Generally L<Catalyst> uses these to influence how the dispatcher sees your |
745 | action and when it will run it in response to an incoming request. They can |
746 | also be used for other things. Here's a summary, but you should refer to the |
aaa85094 |
747 | linked manual page for additional help. |
5b41c28c |
748 | |
749 | =head2 Global |
750 | |
751 | sub homepage :Global { ... } |
752 | |
753 | A global action defined in any controller always runs relative to your root. |
754 | So the above is the same as: |
755 | |
756 | sub myaction :Path("/homepage") { ... } |
757 | |
758 | =head2 Absolute |
759 | |
760 | Status: Deprecated alias to L</Global>. |
761 | |
762 | =head2 Local |
763 | |
764 | Alias to "Path("$action_name"). The following two actions are the same: |
765 | |
766 | sub myaction :Local { ... } |
767 | sub myaction :Path('myaction') { ... } |
768 | |
769 | =head2 Relative |
770 | |
771 | Status: Deprecated alias to L</Local> |
772 | |
773 | =head2 Path |
774 | |
775 | Handle various types of paths: |
776 | |
777 | package MyApp::Controller::Baz { |
778 | |
779 | ... |
780 | |
781 | sub myaction1 :Path { ... } # -> /baz |
c59b922b |
782 | sub myaction2 :Path('foo') { ... } # -> /baz/foo |
5b41c28c |
783 | sub myaction2 :Path('/bar') { ... } # -> /bar |
784 | } |
785 | |
97b0e7a0 |
786 | This is a general toolbox for attaching your action to a given path. |
5b41c28c |

789 | =head2 Regex |

814 | |
815 | =head2 PathPart |
816 | |
817 | =head2 CaptureArgs |
818 | |
480d94b5 |
819 | Allowed values for CaptureArgs is a single integer (CaptureArgs(2), meaning two |
820 | allowed) or you can declare a L<Moose>, L<MooseX::Types> or L<Type::Tiny> |
821 | named constraint such as CaptureArgs(Int,Str) would require two args with |
822 | the first being a Integer and the second a string. You may declare your own |
823 | custom type constraints and import them into the controller namespace: |
824 | |
825 | package MyApp::Controller::Root; |
826 | |
827 | use Moose; |
828 | use MooseX::MethodAttributes; |
829 | use MyApp::Types qw/Int/; |
830 | |
831 | extends 'Catalyst::Controller'; |
832 | |
833 | sub chain_base :Chained(/) CaptureArgs(1) { } |
834 | |
835 | sub any_priority_chain :Chained(chain_base) PathPart('') Args(1) { } |
836 | |
837 | sub int_priority_chain :Chained(chain_base) PathPart('') Args(Int) { } |
838 | |
839 | See L<Catalyst::RouteMatching> for more. |
840 | |
841 | Please see L<Catalyst::DispatchType::Chained> for more. |
5b41c28c |
842 | |
843 | =head2 ActionClass |
844 | |
845 | Set the base class for the action, defaults to L</Catalyst::Action>. It is now |
846 | preferred to use L</Does>. |
847 | |
848 | =head2 MyAction |
849 | |
051a69b9 |
850 | Set the ActionClass using a custom Action in your project namespace. |
851 | |
852 | The following is exactly the same: |
853 | |
854 | sub foo_action1 : Local ActionClass('+MyApp::Action::Bar') { ... } |
855 | sub foo_action2 : Local MyAction('Bar') { ... } |
5b41c28c |
856 | |
857 | =head2 Does |
858 | |
859 | package MyApp::Controller::Zoo; |
860 | |
861 | sub foo : Local Does('Moo') { ... } # Catalyst::ActionRole:: |
862 | sub bar : Local Does('~Moo') { ... } # MyApp::ActionRole::Moo |
863 | sub baz : Local Does('+MyApp::ActionRole::Moo') { ... } |

885 | =head2 Args |
886 | |
887 | When used with L</Path> indicates the number of arguments expected in |
888 | the path. However if no Args value is set, assumed to 'slurp' all |
889 | remaining path pars under this namespace. |
890 | |
480d94b5 |
891 | Allowed values for Args is a single integer (Args(2), meaning two allowed) or you |
892 | can declare a L<Moose>, L<MooseX::Types> or L<Type::Tiny> named constraint such |
893 | as Args(Int,Str) would require two args with the first being a Integer and the |
894 | second a string. You may declare your own custom type constraints and import |
895 | them into the controller namespace: |
896 | |
897 | package MyApp::Controller::Root; |
898 | |
899 | use Moose; |
900 | use MooseX::MethodAttributes; |
901 | use MyApp::Types qw/Tuple Int Str StrMatch UserId/; |
902 | |
903 | extends 'Catalyst::Controller'; |
904 | |
905 | sub user :Local Args(UserId) { |
906 | my ($self, $c, $int) = @_; |
907 | } |
908 | |
909 | sub an_int :Local Args(Int) { |
910 | my ($self, $c, $int) = @_; |
911 | } |
912 | |
913 | sub many_ints :Local Args(ArrayRef[Int]) { |
914 | my ($self, $c, @ints) = @_; |
915 | } |
916 | |
917 | sub match :Local Args(StrMatch[qr{\d\d-\d\d-\d\d}]) { |
918 | my ($self, $c, $int) = @_; |
919 | } |
920 | |
75ce30d0 |
921 | If you choose not to use imported type constraints (like L<Type::Tiny>, or <MooseX::Types> |
922 | you may use L<Moose> 'stringy' types however just like when you use these types in your |
923 | declared attributes you must quote them: |
924 | |
925 | sub my_moose_type :Local Args('Int') { ... } |
926 | |

927 | If you use 'reference' type constraints (such as ArrayRef[Int]) that have an unknown |
928 | number of allowed matches, we set this the same way "Args" is. Please keep in mind |
79fb8f95 |
929 | that actions with an undetermined number of args match at lower precedence than those |
d9f0a350 |
930 | with a fixed number. You may use reference types such as Tuple from L<Types::Standard> |
931 | that allows you to fix the number of allowed args. For example Args(Tuple[Int,Int]) |
932 | would be determined to be two args (or really the same as Args(Int,Int).) You may |
933 | find this useful for creating custom subtypes with complex matching rules that you |
934 | wish to reuse over many actions. |

938 | =head2 Consumes('...') |
939 | |
940 | Matches the current action against the content-type of the request. Typically |
941 | this is used when the request is a POST or PUT and you want to restrict the |
942 | submitted content type. For example, you might have an HTML for that either |
943 | returns classic url encoded form data, or JSON when Javascript is enabled. In |
944 | this case you may wish to match either incoming type to one of two different |
945 | actions, for properly processing. |
946 | |
947 | Examples: |
948 | |
949 | sub is_json : Chained('start') Consumes('application/json') { ... } |
950 | sub is_urlencoded : Chained('start') Consumes('application/x-www-form-urlencoded') { ... } |
951 | sub is_multipart : Chained('start') Consumes('multipart/form-data') { ... } |
952 | |
953 | To reduce boilerplate, we include the following content type shortcuts: |
954 | |
955 | Examples |
956 | |
957 | sub is_json : Chained('start') Consume(JSON) { ... } |
958 | sub is_urlencoded : Chained('start') Consumes(UrlEncoded) { ... } |
959 | sub is_multipart : Chained('start') Consumes(Multipart) { ... } |
960 | |
961 | You may specify more than one match: |
962 | |
963 | sub is_more_than_one |
964 | : Chained('start') |
965 | : Consumes('application/x-www-form-urlencoded') |
966 | : Consumes('multipart/form-data') |
967 | |
968 | sub is_more_than_one |
969 | : Chained('start') |
970 | : Consumes(UrlEncoded) |
971 | : Consumes(Multipart) |
972 | |
973 | Since it is a common case the shortcut C<HTMLForm> matches both |
974 | 'application/x-www-form-urlencoded' and 'multipart/form-data'. Here's the full |
975 | list of available shortcuts: |
976 | |
977 | JSON => 'application/json', |
978 | JS => 'application/javascript', |
979 | PERL => 'application/perl', |
980 | HTML => 'text/html', |
981 | XML => 'text/XML', |
982 | Plain => 'text/plain', |
983 | UrlEncoded => 'application/x-www-form-urlencoded', |
984 | Multipart => 'multipart/form-data', |
985 | HTMLForm => ['application/x-www-form-urlencoded','multipart/form-data'], |
986 | |
987 | Please keep in mind that when dispatching, L<Catalyst> will match the first most |
efba3342 |
988 | relevant case, so if you use the C<Consumes> attribute, you should place your |
68c372d1 |
989 | most accurate matches early in the Chain, and your 'catchall' actions last. |
990 | |
991 | See L<Catalyst::ActionRole::ConsumesContent> for more. |

993 | =head2 Scheme(...) |
994 | |
995 | Allows you to specify a URI scheme for the action or action chain. For example |
996 | you can required that a given path be C<https> or that it is a websocket endpoint |
997 | C<ws> or C<wss>. For an action chain you may currently only have one defined |
998 | Scheme. |
999 | |
1000 | package MyApp::Controller::Root; |
1001 | |
1002 | use base 'Catalyst::Controller'; |
1003 | |
1004 | sub is_http :Path(scheme) Scheme(http) Args(0) { |
1005 | my ($self, $c) = @_; |
1006 | $c->response->body("is_http"); |
1007 | } |
1008 | |
1009 | sub is_https :Path(scheme) Scheme(https) Args(0) { |
1010 | my ($self, $c) = @_; |
1011 | $c->response->body("is_https"); |
1012 | } |
1013 | |
1014 | In the above example http://localhost/root/scheme would match the first |
1015 | action (is_http) but https://localhost/root/scheme would match the second. |
1016 | |
1017 | As an added benefit, if an action or action chain defines a Scheme, when using |
1018 | $c->uri_for the scheme of the generated URL will use what you define in the action |
1019 | or action chain (the current behavior is to set the scheme based on the current |
1020 | incoming request). This makes it easier to use uri_for on websites where some |
1021 | paths are secure and others are not. You may also use this to other schemes |
1022 | like websockets. |
1023 | |
1024 | See L<Catalyst::ActionRole::Scheme> for more. |

1026 | =head1 OPTIONAL METHODS |
1027 | |
1028 | =head2 _parse_[$name]_attr |
1029 | |
1030 | Allows you to customize parsing of subroutine attributes. |
1031 | |
1032 | sub myaction1 :Path TwoArgs { ... } |
1033 | |
1034 | sub _parse_TwoArgs_attr { |
1035 | my ( $self, $c, $name, $value ) = @_; |
1036 | # $self -> controller instance |
1037 | # |
1038 | return(Args => 2); |
1039 | } |
1040 | |
1041 | Please note that this feature does not let you actually assign new functions |
1042 | to actions via subroutine attributes, but is really more for creating useful |
1043 | aliases to existing core and extended attributes, and transforms based on |
1044 | existing information (like from configuration). Code for actually doing |
1045 | something meaningful with the subroutine attributes will be located in the |
1046 | L<Catalyst::Action> classes (or your subclasses), L<Catalyst::Dispatcher> and |
1047 | in subclasses of L<Catalyst::DispatchType>. Remember these methods only get |
1048 | called basically once when the application is starting, not per request! |
