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