44 This Catalyst::Plugin::Session storage module saves session data in
45 your database via DBIx::Class. It's actually just a wrapper around
46 Catalyst::Plugin::Session::Store::Delegate; if you need complete
47 control over how your sessions are stored, you probably want to use
48 that instead.
49
51 setup_finished
52 Hook into the configured session class.
53 session_store_dbic_class
55 Return the DBIx::Class class name to be passed to "$c->model".
56 Defaults to "DBIC::Session".
57 session_store_dbic_id_field
59 Return the configured ID field name. Defaults to "id".
60 session_store_dbic_data_field
62 Return the configured data field name. Defaults to "session_data".
63 session_store_dbic_expires_field
65 Return the configured expires field name. Defaults to "expires".
66 session_store_model
68 Return the model used to find a session.
69 get_session_store_delegate
71 Load the row corresponding to the specified session ID. If none is
72 found, one is automatically created.
73 session_store_delegate_key_to_accessor
75 Match the specified key and operation to the session ID and field name.
76 delete_session_data
78 Delete the specified session from the backend store.
79 delete_expired_sessions
81 Delete all expired sessions.
82
84 The following parameters should be placed in your application
85 configuration under the "Plugin::Session" key.
86 dbic_class
88 (Required) The name of the DBIx::Class that represents a session in the
89 database. It is recommended that you provide only the part after
90 "MyApp::Model", e.g. "DBIC::Session".
91 If you are using Catalyst::Model::DBIC::Schema, the following layout is
93 recommended:
94 · "MyApp::Schema" - your DBIx::Class::Schema class
96 · "MyApp::Schema::Session" - your session table class
98 · "MyApp::Model::DBIC" - your Catalyst::Model::DBIC::Schema class
100 This module will then use "$c->model" to access the appropriate result
102 source from the composed schema matching the "dbic_class" name.
103 For more information, please see Catalyst::Model::DBIC::Schema.
105 expires
107 Number of seconds for which sessions are active.
108 Note that no automatic cleanup is done on your session data. To delete
110 expired sessions, you can use the "delete_expired_sessions" method with
111 Catalyst::Plugin::Scheduler.
112 id_field
114 The name of the field on your sessions table which stores the session
115 ID. Defaults to "id".
116 data_field
118 The name of the field on your sessions table which stores session data.
119 Defaults to "session_data" for compatibility with
120 Catalyst::Plugin::Session::Store::DBI.
121 expires_field
123 The name of the field on your sessions table which stores the
124 expiration time of the session. Defaults to "expires".
125
127 Your sessions table should contain the following columns:
128 id CHAR(72) PRIMARY KEY
130 session_data TEXT
131 expires INTEGER
132 The "id" column should probably be 72 characters. It needs to handle
134 the longest string that can be returned by "generate_session_id" in
135 Catalyst::Plugin::Session, plus another eight characters for internal
136 use. This is less than 72 characters when SHA-1 or MD5 is used, but
137 SHA-256 will need all 72 characters.
138 The "session_data" column should be a long text field. Session data is
140 encoded using MIME::Base64 before being stored in the database.
141 Note that MySQL "TEXT" fields only store 64 kB, so if your session data
143 will exceed that size you'll want to use "MEDIUMTEXT", "MEDIUMBLOB", or
144 larger. If you configure your DBIx::Class::ResultSource to include the
145 size of the column, you will receive warnings for this problem:
146 This session requires 1180 bytes of storage, but your database
148 column 'session_data' can only store 200 bytes. Storing this
149 session may not be reliable; increase the size of your data field
150 See "add_columns" in DBIx::Class::ResultSource for more information.
152 The "expires" column stores the future expiration time of the session.
154 This may be null for per-user and flash sessions.
155 Note that you can change the column names using the "id_field",
157 "data_field", and "expires_field" configuration parameters. However,
158 the column types must match the above.
