13 | Examples: |
14 | |
07f39b47 |
15 | $ dbicdump schema.conf |
16 | |
667f1a0b |
17 | $ dbicdump -o dump_directory=./lib \ |
18 | -o components='["InflateColumn::DateTime"]' \ |
c4a69b87 |
19 | MyApp::Schema dbi:SQLite:./foo.db |
20 | |
21 | $ dbicdump -o dump_directory=./lib \ |
22 | -o components='["InflateColumn::DateTime"]' \ |
667f1a0b |
23 | MyApp::Schema dbi:SQLite:./foo.db '{ quote_char => "\"" }' |
24 | |
112415f1 |
25 | $ dbicdump -Ilib -o dump_directory=./lib \ |
667f1a0b |
26 | -o components='["InflateColumn::DateTime"]' \ |
27 | -o preserve_case=1 \ |
28 | MyApp::Schema dbi:mysql:database=foo user pass '{ quote_char => "`" }' |
29 | |

30 | $ dbicdump -o dump_directory=./lib \ |
31 | -o components='["InflateColumn::DateTime"]' \ |
32 | MyApp::Schema 'dbi:mysql:database=foo;host=domain.tld;port=3306' user pass |

34 | On Windows that would be: |
35 | |
36 | $ dbicdump -o dump_directory=.\lib ^ |
37 | -o components="[q{InflateColumn::DateTime}]" ^ |
38 | -o preserve_case=1 ^ |
39 | MyApp::Schema dbi:mysql:database=foo user pass "{ quote_char => q{`} }" |

41 | Configuration files must have schema_class and connect_info sections, |
07f39b47 |
42 | an example of a general config file is as follows: |
43 | |
44 | schema_class MyApp::Schema |
112415f1 |
45 | |
46 | lib /extra/perl/libs |
07f39b47 |
47 | |
48 | # connection string |
49 | <connect_info> |
50 | dsn dbi:mysql:example |
51 | user root |
52 | pass secret |
53 | </connect_info> |
54 | |
55 | # dbic loader options |
56 | <loader_options> |
e946f659 |
57 | dump_directory ./lib |
58 | components InflateColumn::DateTime |
59 | components TimeStamp |
07f39b47 |
60 | </loader_options> |

62 | Using a config file requires L<Config::Any> installed. |
63 | |
112415f1 |
64 | The optional C<lib> key is equivalent to the C<-I> option. |
65 | |

66 | =head1 DESCRIPTION |
67 | |
68 | Dbicdump generates a L<DBIx::Class> schema using |
69 | L<DBIx::Class::Schema::Loader/make_schema_at> and dumps it to disk. |
70 | |
e83cb149 |
71 | You can pass any L<DBIx::Class::Schema::Loader::Base> constructor option using |
ff746964 |
72 | C<< -o <option>=<value> >>. For convenience, option names will have C<-> |
73 | replaced with C<_> and values that look like references or quote-like |
74 | operators will be C<eval>-ed before being passed to the constructor. |
75 | |
76 | The C<dump_directory> option defaults to the current directory if not |
77 | specified. |
