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

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