83 | =head1 DESCRIPTION |
84 | |
e84a43c1 |
85 | This module provides methods to apply DDL changes to your database using SQL |
86 | diff files. Normally these diff files would be created using |
87 | L<DBIx::Class::Schema/create_ddl_dir>. |
8424c090 |
88 | |
b4b1e91c |
89 | A table called I<dbix_class_schema_versions> is created and maintained by the |
e84a43c1 |
90 | module. This is used to determine which version your database is currently at. |
91 | Similarly the $VERSION in your DBIC schema class is used to determine the |
92 | current DBIC schema version. |
8424c090 |
93 | |
e84a43c1 |
94 | The upgrade is initiated manually by calling C<upgrade> on your schema object, |
95 | this will attempt to upgrade the database from its current version to the current |
96 | schema version using a diff from your I<upgrade_directory>. If a suitable diff is |
97 | not found then no upgrade is possible. |
8424c090 |
98 | |
99 | NB: At the moment, only SQLite and MySQL are supported. This is due to |
100 | spotty behaviour in the SQL::Translator producers, please help us by |
e63a82f7 |
101 | enhancing them. Ask on the mailing list or IRC channel for details (community details |
e84a43c1 |
102 | in L<DBIx::Class>). |
93e4d41a |
103 | |
104 | =head1 GETTING STARTED |
105 | |
e84a43c1 |
106 | Firstly you need to setup your schema class as per the L</SYNOPSIS>, make sure |
107 | you have specified an upgrade_directory and an initial $VERSION. |
93e4d41a |
108 | |
e84a43c1 |
109 | Then you'll need two scripts, one to create DDL files and diffs and another to perform |
110 | upgrades. Your creation script might look like a bit like this: |
93e4d41a |
111 | |
e84a43c1 |
112 | use strict; |
113 | use Pod::Usage; |
114 | use Getopt::Long; |
115 | use MyApp::Schema; |
8424c090 |
116 | |
e84a43c1 |
117 | my ( $preversion, $help ); |
118 | GetOptions( |
119 | 'p|preversion:s' => \$preversion, |
120 | ) or die pod2usage; |
8424c090 |
121 | |
e84a43c1 |
122 | my $schema = MyApp::Schema->connect( |
123 | $dsn, |
124 | $user, |
125 | $password, |
126 | ); |
127 | my $sql_dir = './sql'; |
128 | my $version = $schema->schema_version(); |
129 | $schema->create_ddl_dir( 'MySQL', $version, $sql_dir, $preversion ); |
8424c090 |
130 | |
e84a43c1 |
131 | Then your upgrade script might look like so: |
132 | |
133 | use strict; |
134 | use MyApp::Schema; |
135 | |
136 | my $schema = MyApp::Schema->connect( |
137 | $dsn, |
138 | $user, |
139 | $password, |
140 | ); |
8424c090 |
141 | |
e84a43c1 |
142 | if (!$schema->get_db_version()) { |
143 | # schema is unversioned |
144 | $schema->deploy(); |
145 | } else { |
146 | $schema->upgrade(); |
147 | } |
148 | |
149 | The script above assumes that if the database is unversioned then it is empty |
150 | and we can safely deploy the DDL to it. However things are not always so simple. |
151 | |
152 | if you want to initialise a pre-existing database where the DDL is not the same |
153 | as the DDL for your current schema version then you will need a diff which |
154 | converts the database's DDL to the current DDL. The best way to do this is |
155 | to get a dump of the database schema (without data) and save that in your |
156 | SQL directory as version 0.000 (the filename must be as with |
157 | L<DBIx::Class::Schema/ddl_filename>) then create a diff using your create DDL |
158 | script given above from version 0.000 to the current version. Then hand check |
159 | and if necessary edit the resulting diff to ensure that it will apply. Once you have |
160 | done all that you can do this: |
161 | |
162 | if (!$schema->get_db_version()) { |
163 | # schema is unversioned |
164 | $schema->install("0.000"); |
165 | } |
166 | |
167 | # this will now apply the 0.000 to current version diff |
168 | $schema->upgrade(); |
169 | |
170 | In the case of an unversioned database the above code will create the |
171 | dbix_class_schema_versions table and write version 0.000 to it, then |
172 | upgrade will then apply the diff we talked about creating in the previous paragraph |
173 | and then you're good to go. |

261 | Virtual method that should be overriden to create an upgrade file. |
262 | This is useful in the case of upgrading across multiple versions |
263 | to concatenate several files to create one upgrade file. |

265 | You'll probably want the db_version retrieved via $self->get_db_version |
266 | and the schema_version which is retrieved via $self->schema_version |

278 | |

339 | any number of times to run the actual SQL commands, and in between you can |
340 | sandwich your data upgrading. For example, first run all the B<CREATE> |
341 | commands, then migrate your data from old to new tables/formats, then |
e7b14c5b |
342 | issue the DROP commands when you are finished. Will run the whole file as it is by default. |

360 | C<do_upgrade> method, running whichever commands you specify via the |

445 | Overloaded method. This checks the DBIC schema version against the DB version and |
446 | warns if they are not the same or if the DB is unversioned. It also provides |
447 | compatibility between the old versions table (SchemaVersions) and the new one |
448 | (dbix_class_schema_versions). |
449 | |

450 | To avoid the checks on connect, set the env var DBIC_NO_VERSION_CHECK or alternatively you can set the ignore_version attr in the forth argument like so: |
