NAME
SQL::Translator::Producer::GraphViz - GraphViz producer for SQL::TranslatorSYNOPSIS
use SQL::Translator; my $trans = SQL::Translator->new( from => 'MySQL', # or your db of choice to => 'GraphViz', producer_args => { out_file => 'schema.png', bgcolor => 'lightgoldenrodyellow', show_constraints => 1, show_datatypes => 1, show_sizes => 1 } ) or die SQL::Translator->error; $trans->translate or die $trans->error;
DESCRIPTION
Creates a graph of a schema using the amazing graphviz (see http://www.graphviz.org/) application (via the GraphViz module). It's nifty---you should try it!PRODUCER ARGS
All GraphViz constructor attributes are accepted and passed through to ``new'' in GraphViz. The following defaults are assumed for some attributes:layout => 'dot', overlap => 'false', node => { shape => 'record', style => 'filled', fillcolor => 'white', }, # in inches width => 8.5, height => 11,
See the documentation of ``new'' in GraphViz for more info on these and other attributes.
In addition this producer accepts the following arguments:
- *
- skip_tables
An arrayref or a comma-separated list of table names that should be skipped. Note that a skipped table node may still appear if another table has foreign key constraints pointing to the skipped table. If this happens no table field/index information will be included.
- *
- skip_tables_like
An arrayref or a comma-separated list of regular expressions matching table names that should be skipped.
- *
- cluster
Clustering of tables allows you to group and box tables according to function or domain or whatever criteria you choose. The syntax for clustering tables is:
cluster => 'cluster1=table1,table2;cluster2=table3,table4'
Or pass it as an arrayref like so:
cluster => [ 'cluster1=table1,table2', 'cluster2=table3,table4' ]
Or like so:
cluster => [ { name => 'cluster1', tables => [ 'table1', 'table2' ] }, { name => 'cluster2', tables => [ 'table3', 'table4' ] }, ]
- *
- out_file
The name of the file where the resulting GraphViz output will be written. Alternatively an open filehandle can be supplied. If undefined (the default) - the result is returned as a string.
- *
- output_type (DEFAULT: 'png')
This determines which output method will be invoked to generate the graph: "png" translates to "as_png", "ps" to "as_ps" and so on.
- *
- fontname
This sets the global font name (or full path to font file) for node, edge, and graph labels
- *
- fontsize
This sets the global font size for node and edge labels (note that arbitrarily large sizes may be ignored due to page size or graph size constraints)
- *
- show_fields (DEFAULT: true)
If set to a true value, the names of the colums in a table will be displayed in each table's node
- *
- show_fk_only
If set to a true value, only columns which are foreign keys will be displayed in each table's node
- *
- show_datatypes
If set to a true value, the datatype of each column will be displayed next to each column's name; this option will have no effect if the value of "show_fields" is set to false
- *
- friendly_ints
If set to a true value, each integer type field will be displayed as a tinyint, smallint, integer or bigint depending on the field's associated size parameter. This only applies for the "integer" type (and not the "int" type, which is always assumed to be a 32-bit integer); this option will have no effect if the value of "show_fields" is set to false
- *
- friendly_ints_extended
If set to a true value, the friendly ints displayed will take into account the non-standard types, 'tinyint' and 'mediumint' (which, as far as I am aware, is only implemented in MySQL)
- *
- show_sizes
If set to a true value, the size (in bytes) of each CHAR and VARCHAR column will be displayed in parentheses next to the column's name; this option will have no effect if the value of "show_fields" is set to false
- *
- show_constraints
If set to a true value, a field's constraints (i.e., its primary-key-ness, its foreign-key-ness and/or its uniqueness) will appear as a comma-separated list in brackets next to the field's name; this option will have no effect if the value of "show_fields" is set to false
- *
- show_indexes
If set to a true value, each record will also show the indexes set on each table. It describes the index types along with which columns are included in the index.
- *
- show_index_names (DEFAULT: true)
If "show_indexes" is set to a true value, then the value of this parameter determines whether or not to print names of indexes. if "show_index_names" is false, then a list of indexed columns will appear below the field list. Otherwise, it will be a list prefixed with the name of each index.
- *
- natural_join
If set to a true value, ``make_natural_joins'' in SQL::Translator::Schema will be called before generating the graph.
- *
- join_pk_only
The value of this option will be passed as the value of the like-named argument to ``make_natural_joins'' in SQL::Translator::Schema; implies "natural_join => 1"
- *
- skip_fields
The value of this option will be passed as the value of the like-named argument to ``make_natural_joins'' in SQL::Translator::Schema; implies "natural_join => 1"
DEPRECATED ARGS
- *
- node_shape
Deprecated, use node => { shape => ... } instead
- *
- add_color
Deprecated, use bgcolor => 'lightgoldenrodyellow' instead
If set to a true value, the graphic will have a background color of 'lightgoldenrodyellow'; otherwise the default white background will be used
- *
- nodeattrs
Deprecated, use node => { ... } instead
- *
- edgeattrs
Deprecated, use edge => { ... } instead
- *
- graphattrs
Deprecated, use graph => { ... } instead
