# NAME

DBIx::Class::Helper::Row::Types - Use Types to define rows

# VERSION

version v0.3.1

# SYNOPSIS

In result class:

```perl
 use Types::SQL -types;
 use Types::Standard -types;

__PACKAGE__->load_components('Helper::Row::Types');

__PACKAGE__->add_columns(

   id   => Serial,

   name => {
     isa => Maybe[ Varchar[64] ],
   },
);
```

# DESCRIPTION

This helper allows you to specify column information by passing a
[Type::Tiny](https://metacpan.org/pod/Type%3A%3ATiny) object.

Note that this _does not_ enforce that the data is of that type,
unless you specify the `strict` option (See ["set\_column"](#set_column)).  The
main purpose of this is to allow you to use types as a shorthand for
specifying the column type.

You can use types from [Types::SQL](https://metacpan.org/pod/Types%3A%3ASQL) or supported types from
[Types::Standard](https://metacpan.org/pod/Types%3A%3AStandard).

# METHODS

## `add_column`

## `add_columns`

These methods are modified to allow you to specify the column info
using the `isa` attribute and a [Type::Tiny](https://metacpan.org/pod/Type%3A%3ATiny) type.

Note that in no way does this enforce that type.

## `set_column`

If the `strict` attribute is true for the column, then the type
constraint will be enforced when the column is explicitly set.

If the `coerce` attribute is true, then the type's coercion will be
applied before checking the constraint.

Note that type constraints will not be enforced if you use the
`insert` or resultset `create` methods.

This is entirely separate from database-level constraints.

Enabling `strict` for an inflated column is strongly discouraged.

# KNOWN ISSUES

Strict type constraints are only applied when explicitly setting a
column value.
