NAME

6       DBIx::Class::DeploymentHandler::Manual::CatalystIntro - Introduction to
7       using DBIx::Class::DeploymentHandler with a new Catalyst Project
8

Background

10       This introduction will use PostgreSQL and Catalyst.  Background
11       information on using PostgreSQL with Catalyst can be found at
12       Catalyst::Manual::Tutorial::10_Appendices.  This guide will assume that
13       you have some understanding of Catalyst.  Please go through the
14       Catalyst tutorials first if you have not yet done so.
15

Database Setup

17       Start by creating a user "catalyst", with password "catalyst"
18
19        $ sudo -u postgres createuser -P catalyst
20        Enter password for new role: <catalyst>
21        Enter it again: <catalyst>
22        Shall the new role be a superuser? (y/n) n
23        Shall the new role be allowed to create databases? (y/n) n
24        Shall the new role be allowed to create more new roles? (y/n) n
25
26       Then create a new database called "deploymentintro"
27
28        sudo -u postgres createdb -O catalyst deploymentintro
29

Create the project

31        $ catalyst.pl DeploymentIntro
32        $ cd DeploymentIntro
33        $ perl Makefile.PL
34

Create the Schema

36        $ script/deploymentintro_create.pl model DB DBIC::Schema DeploymentIntro::Schema \
37            create=static 'dbi:Pg:dbname=deploymentintro' 'catalyst' 'catalyst' '{ AutoCommit => 1 }'
38
39        $ mkdir -p lib/Schema/Result
40
41       Remove the following from "lib/DeploymentIntro/Model/DB.pm":
42
43        connect_info => {
44          dsn => 'dbi:Pg:dbname=deploymentintro',
45          user => 'catalyst',
46          password => 'catalyst',
47          AutoCommit => q{1},
48        }
49
50       Remove "deploymentintro.conf" and create a new file called
51       "deploymentintro_local.pl" with the following:
52
53           {
54               name => "DeploymentIntro",
55
56               "Model::DB" => {
57                   schema_class => 'DeploymentIntro::Schema',
58
59                   connect_info => {
60                       dsn        => 'dbi:Pg:dbname=deploymentintro',
61                       user       => 'catalyst',
62                       password   => 'catalyst',
63                       AutoCommit => 1,
64                   }
65               }
66           }
67
68       Copy the following program into scripts, under the name
69       "deploymentintro_dbicdh.pl"

226
227        1;
228
229       And then edit "lib/DeploymentIntro/Schema.pm" and add the following
230       above the 1 at the bottom
231
232        our $VERSION = 1;
233
234       Now it is just a matter of running
235
236        ./script/deploymentintro_dbicdh.pl install
