82 Reaction::UI::Controller
86 Controller class used to make displaying collections easier.
87 Inherits from L<Reaction::UI::Controller>.
93 The name of the model this controller will use as it's data source. Should be a
94 name that can be passed to C<$C-E<gt>model>
96 =head2 collection_name
98 The name of the collection whithin the model that this Controller will be
101 =head2 action_viewport_map
105 =item B<_build_action_viewport_map> - Provided builder method, see METHODS
107 =item B<has_action_viewport_map> - Auto generated predicate
109 =item B<clear_action_viewport_map>- Auto generated clearer method
113 Read-write lazy building hashref. The keys should match action names in the
114 Controller and the value should be the ViewPort class that this action should
115 use. See method C<basic_page> for more info.
117 =head2 action_viewport_args
119 Read-write lazy building hashref. Additional ViewPort arguments for the action
120 named as the key in the controller. See method C<basic_page> for more info.
124 =item B<_build_action_viewport_args> - Provided builder method, see METHODS
126 =item B<has_action_viewport_args> - Auto generated predicate
128 =item B<clear_action_viewport_args>- Auto generated clearer method
134 =head2 get_collection $c
136 Returns an instance of the collection this controller uses.
138 =head2 _build_action_viewport_map
140 Provided builder for C<action_viewport_map>. Returns a hash with two items:
142 list => 'Reaction::UI::ViewPort::ListView',
143 view => 'Reaction::UI::ViewPort::Object',
145 =head2 _build_action_viewport_args
147 Returns an empty hashref.
149 =head2 basic_page $c, \%vp_args
151 Accepts two arguments, context, and a hashref of viewport arguments. It will
152 automatically determine the action name using the catalyst stack and call
153 C<push_viewport> with the ViewPort class name contained in the
154 C<action_viewport_map> with a set of options determined by merging C<$vp_args>
155 and the arguments contained in C<action_viewport_args>, if any.
165 Chain link, chained to C<base>. C<list> fetches the collection for the model
166 and calls C<basic_page> with a single argument, C<collection>.
168 The default ViewPort for this action is C<Reaction::UI::ViewPort::ListView> and
169 can be changed by altering the C<action_viewport_map> attribute hash.
173 Chain link, chained to C<base>, captures one argument, 'id'. Attempts to find
174 a single object by searching for a member of the current collection which has a
175 Primary Key or Unique constraint matching that argument. If the object is found
176 it is stored in the stash under the C<object> key.
180 Chain link, chained to C<object>. Calls C<basic page> with one argument,
181 C<model>, which contains an instance of the object fetched by the C<object>
184 The default ViewPort for this action is C<Reaction::UI::ViewPort::Object> and
185 can be changed by altering the C<action_viewport_map> attribute hash.
