73 Apache::MVC - Apache front-end to Maypole
78 use base 'Apache::MVC';

80 BeerDB->config->uri_base("http://your.site/");

82 # Now set up your database:
90 Maypole is a Perl web application framework to Java's struts. It is
91 essentially completely abstracted, and so doesn't know anything about
92 how to talk to the outside world. C<Apache::MVC> is a mod_perl based
95 To use it, you need to create a package which represents your entire
96 application. In our example above, this is the C<BeerDB> package.
98 This needs to first inherit from C<Apache::MVC>, and then call setup.
99 This will give your package an Apache-compatible C<handler> subroutine,
100 and then pass any parameters onto the C<setup_database> method of the
101 model class. The default model class for Maypole uses L<Class::DBI> to
102 map a database to classes, but this can be changed by messing with the
103 configuration. (B<Before> calling setup.)
105 Next, you should configure your application through the C<config>
106 method. Configuration parameters at present are:
112 You B<must> specify this; it is the base URI of the application, which
113 will be used to construct links.
117 If you do not want all of the tables in the database to be accessible,
118 then set this to a list of only the ones you want to display
122 List output is paged if you set this to a positive number of rows.
126 You should also set up relationships between your classes, such that,
127 for instance, calling C<brewery> on a C<BeerDB::Beer> object returns an
128 object representing its associated brewery.
130 For a full example, see the included "beer database" application.
134 Create a driver module like the one above.
136 Put the following in your Apache config:
139 SetHandler perl-script
143 Copy the templates found in F<templates/factory> into the
144 F<beer/factory> directory off the web root. When the designers get
145 back to you with custom templates, they are to go in
146 F<beer/custom>. If you need to do override templates on a
147 database-table-by-table basis, put the new template in
150 This will automatically give you C<add>, C<edit>, C<list>, C<view> and
151 C<delete> commands; for instance, a list of breweries, go to
153 http://your.site/beer/brewery/list
