DBIx::Class::Schema::Loader::RelBuilder - Builds relationships for DBIx::Class::Schema::Loader
SYNOPSIS
See DBIx::Class::Schema::Loader and DBIx::Class::Schema::Loader::Base.
DESCRIPTION
This class builds relationships for DBIx::Class::Schema::Loader. This is module is not (yet) for external use.
METHODS
new
Arguments: $loader object
generate_code
Arguments:
[
[ local_moniker1 (scalar), fk_info1 (arrayref), uniq_info1 (arrayref) ]
[ local_moniker2 (scalar), fk_info2 (arrayref), uniq_info2 (arrayref) ]
...
]
This generates the code for the relationships of each table.
"local_moniker" is the moniker name of the table which had the REFERENCES statements. The fk_info arrayref's contents should take the
form:
[
{
local_table => 'some_table',
local_moniker => 'SomeTable',
local_columns => [ 'col2', 'col3' ],
remote_table => 'another_table_moniker',
remote_moniker => 'AnotherTableMoniker',
remote_columns => [ 'col5', 'col7' ],
},
{
local_table => 'some_other_table',
local_moniker => 'SomeOtherTable',
local_columns => [ 'col1', 'col4' ],
remote_table => 'yet_another_table_moniker',
remote_moniker => 'YetAnotherTableMoniker',
remote_columns => [ 'col1', 'col2' ],
},
# ...
],
The uniq_info arrayref's contents should take the form:
[
[
uniq_constraint_name => [ 'col1', 'col2' ],
],
[
another_uniq_constraint_name => [ 'col1', 'col2' ],
],
],
This method will return the generated relationships as a hashref keyed on the class names. The values are arrayrefs of hashes containing
method name and arguments, like so:
{
'Some::Source::Class' => [
{ method => 'belongs_to', arguments => [ 'col1', 'Another::Source::Class' ],
{ method => 'has_many', arguments => [ 'anothers', 'Yet::Another::Source::Class', 'col15' ],
],
'Another::Source::Class' => [
# ...
],
# ...
}
