46 Apache::MVC - Apache front-end to Maypole
51 use Maypole::Application;
55 A mod_perl platform driver for Maypole. Your application can inherit from
56 Apache::MVC directly, but it is recommended that you use
57 L<Maypole::Application>.
61 Create a driver module like the one illustrated in L<Maypole::Application>.
63 Put the following in your Apache config:
66 SetHandler perl-script
70 Copy the templates found in F<templates/factory> into the F<beer/factory>
71 directory off the web root. When the designers get back to you with custom
72 templates, they are to go in F<beer/custom>. If you need to override templates
73 on a database-table-by-table basis, put the new template in F<beer/I<table>>.
75 This will automatically give you C<add>, C<edit>, C<list>, C<view> and C<delete>
76 commands; for instance, to see a list of breweries, go to
78 http://your.site/beer/brewery/list
80 For more information about how the system works and how to extend it,
85 This class overrides a set of methods in the base Maypole class to provide its
86 functionality. See L<Maypole> for these:
