Hi everyone!
From the ResultSet documentation on the create method
(http://search.cpan.org/~arodland/DBIx-Class/lib/DBIx/Class/ResultSet.pm#create)
I understood that it's able to create related rows in related relationships.
But on my attempt to create the main row with some related I get the
error: "DBIx::Class::ResultSet::create(): Unable to determine
relationship 'images' direction from 'Product', possibly due to a
missing reverse-relationship on 'images' to 'Product'."
My Product table is described below:
__PACKAGE__->load_components("Core");
__PACKAGE__->table("Product");
__PACKAGE__->add_columns(
'id' => {
data_type => 'int',
is_auto_increment => 1,
is_nullable => 0,
},
'productId' => {
data_type => 'varchar',
size => 255,
is_nullable => 0,
},
'data' => {
data_type => 'blob',
is_nullable => 0,
},
);
__PACKAGE__->set_primary_key("id");
__PACKAGE__->has_many(
'images' => 'My::Result::ProductImage',
{ 'foreign.productId' => 'self.id' },
{ cascade_delete => 1, join_type => 'left' }
);
Here is my ProductImage table:
__PACKAGE__->load_components("Core");
__PACKAGE__->table("ProductImage");
__PACKAGE__->add_columns(
'id' => {
data_type => 'int',
is_auto_increment => 1,
is_nullable => 0,
},
'productId' => {
data_type => 'int',
is_nullable => 0,
},
'url' => {
data_type => 'varchar',
size => 255,
is_nullable => 0,
},
);
__PACKAGE__->set_primary_key("id");
__PACKAGE__->belongs_to(
'product' => 'My::Result::Product',
{ 'foreign.id' => 'self.productId' },
{ is_foreign_key_constraint => 0, join_type => 'inner' }
);
I'm trying to perform the insertion like that:
my $product_row = $schema->resultset("Product")->create({
productId => $product->{id},
data => $product->{data},
images => [ { url => 'http://url1' }, { url => 'http://url2' } ],
});
As you can see I have relationships in both directions: has_many and
corresponding belongs_to.
Can you help me to find the problem what I'm dong wrong?
Maybe I misunderstood the documentation and create doesn't do the trick?
