139 | =head1 DESCRIPTION |
140 | |
141 | This authentication store lets you create a very quick and dirty user |
142 | database in your application's config hash. |
143 | |
144 | You will need to include the Authentication plugin, and at least one Credential |
145 | plugin to use this Store. Credential::Password is reccommended. |
146 | |
147 | It's purpose is mainly for testing, and it should probably be replaced by a |
148 | more "serious" store for production. |
149 | |
150 | The hash in the config, as well as the user objects/hashes are freely mutable |
151 | at runtime. |
152 | |
153 | =head1 CONFIGURATION |
154 | |
155 | =over 4 |
156 | |
157 | =item class |
158 | |
159 | The classname used for the store. This is part of |
160 | L<Catalyst::Plugin::Authentication> and is the method by which |
161 | Catalyst::Authentication::Store::Minimal is loaded as the |
162 | user store. For this module to be used, this must be set to |
163 | 'Minimal'. |
164 | |
165 | =item users |
166 | |
167 | This is a simple hash of users, the keys are the usenames, and the values are |
168 | hashrefs containing a password key/value pair, and optionally, a roles/list |
169 | of role-names pair. If using roles, you will also need to add the |
170 | Authorization::Roles plugin. |
171 | |
172 | See the SYNOPSIS for an example. |

175 | |
176 | =head1 METHODS |
177 | |
178 | There are no publicly exported routines in the Minimal store (or indeed in |
179 | most authentication stores) However, below is a description of the routines |
180 | required by L<Catalyst::Plugin::Authentication> for all authentication stores. |
181 | |
182 | =head2 new( $config, $app, $realm ) |
183 | |
184 | Constructs a new store object, which uses the user element of the supplied config |
185 | hash ref as it's backing structure. |
186 | |
187 | =head2 find_user( $authinfo, $c ) |
188 | |
189 | Keys the hash by the 'id' or 'username' element in the authinfo hash and returns the user. |
190 | |
191 | ... documentation fairy stopped here. ... |
192 | |
193 | If the return value is unblessed it will be blessed as |
194 | L<Catalyst::Authentication::User::Hash>. |
195 | |
196 | =head2 from_session( $id ) |
197 | |
198 | Delegates to C<get_user>. |
199 | |
200 | =head2 user_supports( ) |
201 | |
202 | Chooses a random user from the hash and delegates to it. |
203 | |

206 | =head2 setup( ) |
