, which is the current
|
51
|
|
|
|
|
|
|
L table we are producing, |
|
52
|
|
|
|
|
|
|
which you can then use to walk the schema via the methods documented |
|
53
|
|
|
|
|
|
|
in that module. You also get C as a shortcut to the |
|
54
|
|
|
|
|
|
|
L for the table and C, |
|
55
|
|
|
|
|
|
|
the L object for this parse in case you want to get |
|
56
|
|
|
|
|
|
|
access to any of the options etc set here. |

Here's a brief example of what the template could look like: |
|
59
|
|
|
|
|
|
|
|
|
60
|
|
|
|
|
|
|
[% table.name %] |
|
61
|
|
|
|
|
|
|
================ |
|
62
|
|
|
|
|
|
|
[% FOREACH field = table.get_fields %] |
|
63
|
|
|
|
|
|
|
[% field.name %] [% field.data_type %]([% field.size %]) |
|
64
|
|
|
|
|
|
|
[% END -%] |
|
65
|
|
|
|
|
|
|
|
|
66
|
|
|
|
|
|
|
See F for a more complete example. |
|
67
|
|
|
|
|
|
|
|
|
68
|
|
|
|
|
|
|
You can also set any of the options used to initialize the Template |
|
69
|
|
|
|
|
|
|
object by adding them to your producer_args. See Template Toolkit docs |
|
70
|
|
|
|
|
|
|
for details of the options. |
|
71
|
|
|
|
|
|
|
|
|
72
|
|
|
|
|
|
|
$translator = SQL::Translator->new( |
|
73
|
|
|
|
|
|
|
to => 'TT', |
|
74
|
|
|
|
|
|
|
producer_args => { |
|
75
|
|
|
|
|
|
|
ttfile => 'foo_template.tt', |
|
76
|
|
|
|
|
|
|
INCLUDE_PATH => '/foo/templates/tt', |
|
77
|
|
|
|
|
|
|
INTERPOLATE => 1, |
|
78
|
|
|
|
|
|
|
}, |
|
79
|
|
|
|
|
|
|
); |
|
80
|
|
|
|
|
|
|
|
|
81
|
|
|
|
|
|
|
If you set C and its additional options the producer will |
|
82
|
|
|
|
|
|
|
write a separate file for each table in the schema. This is useful for |
|
83
|
|
|
|
|
|
|
producing things like HTML documentation where every table gets its |
|
84
|
|
|
|
|
|
|
own page (you could also use TTSchema producer to add an index page). |
|
85
|
|
|
|
|
|
|
It's also particularly good for code generation where you want to |
|
86
|
|
|
|
|
|
|
produce a class file per table. |

returning the whole lot back to the Translalor and hence STDOUT). The |

What to do if we are running with mk_files and a file already exists |
|
120
|
|
|
|
|
|
|
where we want to write our output. One of "skip", "die", "replace", |

"insert". The default is die. |

B - Over-write the existing file with the new one, clobbering |

124

|
|
|
|
|
|
anything already there. |
|
125
|
|
|
|
|
|
|
|
|
126
|
|
|
|
|
|
|
B - Leave the original file as it was and don't write the new |
|
127
|
|
|
|
|
|
|
version anywhere. |
|
128
|
|
|
|
|
|
|
|
|
129
|
|
|
|
|
|
|
B - Die with an existing file error. |
|
130
|
|
|
|
|
|
|
|
|
131
|
|
|
|
|
|
|
B - Insert the generated output into the file between a set of |
|
132
|
|
|
|
|
|
|
special comments (defined by the following options.) Any code between |
|
133
|
|
|
|
|
|
|
the comments will be overwritten (ie the results from a previous |
|
134
|
|
|
|
|
|
|
produce) but the rest of the file is left alone (your custom code). |
|
135
|
|
|
|
|
|
|
This is particularly useful for code generation as it allows you to |
|
136
|
|
|
|
|
|
|
generate schema derived code and then add your own custom code |
|
137
|
|
|
|
|
|
|
to the file. Then when the schema changes you just re-produce to |
|
138
|
|
|
|
|
|
|
insert the new code. |
