67 # find_user is capable of doing the same by simply passing { id => $id }
68 # no new code should be written using get_user as it is deprecated.

74 ## backwards compatibility
78 ### If a user does 'use Catalyst qw/Authentication::Store::Minimal/'
79 ### he will be proxied on to this setup routine (and only then --
80 ### non plugins should NOT have their setup routine invoked!)
81 ### Beware what we pass to the 'new' routine; it wants
82 ### a config has with a top level key 'users'. New style
83 ### configs do not have this, and split by realms. If we
84 ### blindly pass this to new, we will 1) overwrite what we
85 ### already passed and 2) make ->userhash undefined, which
87 ### Can't use an undefined value as a HASH reference at
88 ### lib/Catalyst/Authentication/Store/Minimal.pm line 38.
90 ### So only do this compatibility call if:
91 ### 1) we have a {users} config directive
93 ### Ideally we could also check for:
94 ### 2) we don't already have a ->userhash
95 ### however, that's an attribute of an object we can't

115 Catalyst::Authentication::Store::Minimal - Minimal authentication store
119 # you probably just want Store::Minimal under most cases,
120 # but if you insist you can instantiate your own store:
122 use Catalyst::Authentication::Store::Minimal;
128 __PACKAGE__->config->{'Plugin::Authentication'} =
130 default_realm => 'members',
135 password_field => 'password',
136 password_type => 'clear'
142 password => "s00p3r",
144 roles => [qw/edit delete/],
147 password => "s3cr3t",
148 roles => [qw/comment/],
159 This authentication store lets you create a very quick and dirty user
160 database in your application's config hash.
162 You will need to include the Authentication plugin, and at least one Credential
163 plugin to use this Store. Credential::Password is reccommended.
165 It's purpose is mainly for testing, and it should probably be replaced by a
166 more "serious" store for production.
168 The hash in the config, as well as the user objects/hashes are freely mutable
177 The classname used for the store. This is part of
178 L<Catalyst::Plugin::Authentication> and is the method by which
179 Catalyst::Authentication::Store::Minimal is loaded as the
180 user store. For this module to be used, this must be set to
185 This is a simple hash of users, the keys are the usenames, and the values are
186 hashrefs containing a password key/value pair, and optionally, a roles/list
187 of role-names pair. If using roles, you will also need to add the
188 Authorization::Roles plugin.
190 See the SYNOPSIS for an example.
196 There are no publicly exported routines in the Minimal store (or indeed in
197 most authentication stores) However, below is a description of the routines
198 required by L<Catalyst::Plugin::Authentication> for all authentication stores.
200 =head2 new( $config, $app, $realm )
202 Constructs a new store object, which uses the user element of the supplied config
203 hash ref as it's backing structure.
205 =head2 find_user( $authinfo, $c )
207 Keys the hash by the 'id' or 'username' element in the authinfo hash and returns the user.
209 ... documentation fairy stopped here. ...
211 If the return value is unblessed it will be blessed as
212 L<Catalyst::Authentication::User::Hash>.
214 =head2 from_session( $id )
216 Delegates to C<get_user>.
218 =head2 user_supports( )
220 Chooses a random user from the hash and delegates to it.
