9 package Foo::Controller::Bar;
10
11 __PACKAGE__->config(
12 'default' => 'text/x-yaml',
13 'stash_key' => 'rest',
14 'map' => {
15 'text/html' => [ 'View', 'TT', ],
16 'text/x-yaml' => 'YAML',
17 'text/x-data-dumper' => [ 'Data::Serializer', 'Data::Dumper' ],
18 }
19 );

21 sub end :ActionClass('Serialize') {}
22
24 This action will serialize the body of an HTTP Response. The
25 serializer is selected by introspecting the HTTP Requests content-type
26 header.
27
28 It requires that your Catalyst controller is properly configured to set
29 up the mapping between Content Type's and Serialization classes.
30
31 The specifics of serializing each content-type is implemented as a
32 plugin to Catalyst::Action::Serialize.
33
34 Typically, you would use this ActionClass on your "end" method.
35 However, nothing is stopping you from choosing specific methods to
36 Serialize:
37
38 sub foo :Local :ActionClass('Serialize') {
39 .. populate stash with data ..
40 }
41
42 When you use this module, the request class will be changed to
43 Catalyst::Request::REST.
44
46 map
47 Takes a hashref, mapping Content-Types to a given serializer plugin.
48
49 default
50 This is the 'fall-back' Content-Type if none of the requested or
51 acceptable types is found in the "map". It must be an entry in the
52 "map".
53
54 stash_key
55 Specifies the key of the stash entry holding the data that is to be
56 serialized. So if the value is "rest", we will serialize the data
57 under:
58
59 $c->stash->{'rest'}
60
61 content_type_stash_key
62 Specifies the key of the stash entry that optionally holds an
63 overriding Content-Type. If set, and if the specified stash entry has a
64 valid value, then it takes priority over the requested content types.
65
66 This can be useful if you want to dynamically force a particular
67 content type, perhaps for debugging.

70 Daisuke Maki pointed out that early versions of this Action did not
71 play well with others, or generally behave in a way that was very
72 consistent with the rest of Catalyst.
73
75 For building custom error responses when serialization fails, you can
76 create an ActionRole (and use Catalyst::Controller::ActionRole to apply
77 it to the "end" action) which overrides "unsupported_media_type" and/or
78 "serialize_bad_request" methods.
79
81 You likely want to look at Catalyst::Controller::REST, which implements
82 a sensible set of defaults for doing a REST controller.
