33 Apache::MVC - Apache front-end to Maypole
38 use base 'Apache::MVC';
39 BeerDB->setup("dbi:mysql:beerdb");
40 BeerDB->config->{uri_base} = "http://your.site/";
41 BeerDB->config->{display_tables} = [qw[beer brewery pub style]];
42 # Now set up your database:
50 Maypole is a Perl web application framework to Java's struts. It is
51 essentially completely abstracted, and so doesn't know anything about
52 how to talk to the outside world. C<Apache::MVC> is a mod_perl based
55 To use it, you need to create a package which represents your entire
56 application. In our example above, this is the C<BeerDB> package.
58 This needs to first inherit from C<Apache::MVC>, and then call setup.
59 This will give your package an Apache-compatible C<handler> subroutine,
60 and then pass any parameters onto the C<setup_database> method of the
61 model class. The default model class for Maypole uses L<Class::DBI> to
62 map a database to classes, but this can be changed by messing with the
63 configuration. (B<Before> calling setup.)
65 Next, you should configure your application through the C<config>
66 method. Configuration parameters at present are:
72 You B<must> specify this; it is the base URI of the application, which
73 will be used to construct links.
77 If you do not want all of the tables in the database to be accessible,
78 then set this to a list of only the ones you want to display
82 List output is paged if you set this to a positive number of rows.
86 You should also set up relationships between your classes, such that,
87 for instance, calling C<brewery> on a C<BeerDB::Beer> object returns an
88 object representing its associated brewery.
90 For a full example, see the included "beer database" application.
94 Create a driver module like the one above.
96 Put the following in your Apache config:
99 SetHandler perl-script
103 Copy the templates found in F<templates/factory> into the
104 F<beer/factory> directory off the web root. When the designers get
105 back to you with custom templates, they are to go in
106 F<beer/custom>. If you need to do override templates on a
107 database-table-by-table basis, put the new template in
110 This will automatically give you C<add>, C<edit>, C<list>, C<view> and
111 C<delete> commands; for instance, a list of breweries, go to
113 http://your.site/beer/brewery/list
