+Hashref of attributes to pass to each generated relationship, listed by type.
+Also supports relationship type 'all', containing options to pass to all
+generated relationships. Attributes set for more specific relationship types
+override those set in 'all', and any attributes specified by this option
+override the introspected attributes of the foreign key if any.
For example:
relationship_attrs => {
- belongs_to => { is_deferrable => 0 },
+ has_many => { cascade_delete => 1, cascade_copy => 1 },
+ might_have => { cascade_delete => 1, cascade_copy => 1 },
},
-use this to turn off DEFERRABLE on your foreign key constraints.
+use this to turn L<DBIx::Class> cascades to on on your
+L<has_many|DBIx::Class::Relationship/has_many> and
+L<might_have|DBIx::Class::Relationship/might_have> relationships, they default
+to off.
+
+Can also be a coderef, for more precise control, in which case the coderef gets
+this hash of parameters (as a list:)
+
+ rel_name # the name of the relationship
+ rel_type # the type of the relationship: 'belongs_to', 'has_many' or 'might_have'
+ local_source # the DBIx::Class::ResultSource object for the source the rel is *from*
+ remote_source # the DBIx::Class::ResultSource object for the source the rel is *to*
+ local_table # a DBIx::Class::Schema::Loader::Table object for the table of the source the rel is from
+ local_cols # an arrayref of column names of columns used in the rel in the source it is from
+ remote_table # a DBIx::Class::Schema::Loader::Table object for the table of the source the rel is to
+ remote_cols # an arrayref of column names of columns used in the rel in the source it is to
+ attrs # the attributes that would be set
+
+it should return the new hashref of attributes, or nothing for no changes.
+
+For example:
+
+ relationship_attrs => sub {
+ my %p = @_;
+
+ say "the relationship name is: $p{rel_name}";
+ say "the relationship is a: $p{rel_type}";
+ say "the local class is: ", $p{local_source}->result_class;
+ say "the remote class is: ", $p{remote_source}->result_class;
+ say "the local table is: ", $p{local_table}->sql_name;
+ say "the rel columns in the local table are: ", (join ", ", @{$p{local_cols}});
+ say "the remote table is: ", $p{remote_table}->sql_name;
+ say "the rel columns in the remote table are: ", (join ", ", @{$p{remote_cols}});
+
+ if ($p{local_table} eq 'dogs' && @{$p{local_cols}} == 1 && $p{local_cols}[0] eq 'name') {
+ $p{attrs}{could_be_snoopy} = 1;
+
+ reutrn $p{attrs};
+ }
+ },
+
+These are the default attributes:
+
+ has_many => {
+ cascade_delete => 0,
+ cascade_copy => 0,
+ },
+ might_have => {
+ cascade_delete => 0,
+ cascade_copy => 0,
+ },
+ belongs_to => {
+ on_delete => 'CASCADE',
+ on_update => 'CASCADE',
+ is_deferrable => 1,
+ },
+
+For L<belongs_to|DBIx::Class::Relationship/belongs_to> relationships, these
+defaults are overridden by the attributes introspected from the foreign key in
+the database, if this information is available (and the driver is capable of
+retrieving it.)
+
+This information overrides the defaults mentioned above, and is then itself
+overridden by the user's L</relationship_attrs> for C<belongs_to> if any are
+specified.
+
+In general, for most databases, for a plain foreign key with no rules, the
+values for a L<belongs_to|DBIx::Class::Relationship/belongs_to> relationship
+will be:
+
+ on_delete => 'NO ACTION',
+ on_update => 'NO ACTION',
+ is_deferrable => 0,
+
+In the cases where an attribute is not supported by the DB, a value matching
+the actual behavior is used, for example Oracle does not support C<ON UPDATE>
+rules, so C<on_update> is set to C<NO ACTION>. This is done so that the
+behavior of the schema is preserved when cross deploying to a different RDBMS
+such as SQLite for testing.
+
+In the cases where the DB does not support C<DEFERRABLE> foreign keys, the
+value is set to C<1> if L<DBIx::Class> has a working C<<
+$storage->with_deferred_fk_checks >>. This is done so that the same
+L<DBIx::Class> code can be used, and cross deployed from and to such databases.
