70 Apache::MVC - Apache front-end to Maypole

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