DBIx::Class::ResultSet 在多个唯一约束上更新或创建
我想知道是否可以对 dbix
Ex From Cpan 中的多个唯一约束进行 update_or_create：
my $cd = $schema->resultset('CD')->update_or_create(
{
artist => 'Massive Attack',
title => 'Mezzanine',
year => 1998,
},
{ key => 'cd_artist_title' }
);
我想做什么
my $cd = $schema->resultset('CD')->update_or_create(
{
artist => 'Massive Attack',
title => 'Mezzanine',
year => 1998,
},
{ key => {'cd_artist_title','year' }
);
I was wondering if it is possible update_or_create on multiple unique constraints in dbix
Ex From Cpan:
my $cd = $schema->resultset('CD')->update_or_create(
{
artist => 'Massive Attack',
title => 'Mezzanine',
year => 1998,
},
{ key => 'cd_artist_title' }
);
What I would like to do
my $cd = $schema->resultset('CD')->update_or_create(
{
artist => 'Massive Attack',
title => 'Mezzanine',
year => 1998,
},
{ key => {'cd_artist_title','year' }
);

我想通了：您必须使用
在控制器中定义唯一约束add_unique_constraint。I figured it out: you have to define the unique constraint in the Controller with
add_unique_constraint.
