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

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