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

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