Can someone explain how this works? (3 Replies)

tangram::type::array::scalar
Tangram::Type::Array::Scalar(3pm) User Contributed Perl Documentation Tangram::Type::Array::Scalar(3pm)
NAME
Tangram::Type/Array/Scalar - map Perl array of strings or numbers
SYNOPSIS
use Tangram::Core;
use Tangram::Type/Array/Scalar; # always
$schema = Tangram::Schema->new(
classes => { NaturalPerson => { fields => {
flat_array =>
{
interests =>
{
table => 'NP_int',
sql => 'VARCHAR(50)',
},
lucky_numbers => 'int', # use defaults
}
DESCRIPTION
Maps references to a Perl array. The persistent fields are grouped in a hash under the "array" key in the field hash.
The array may contain only 'simple' scalars like integers, strings or real numbers. It may not contain references. For arrays of objects,
see Tangram::Type::Array::FromMany and Tangram::Type::Array::FromOne.
Tangram uses a table to save the state of the collection. The table has three columns, which contain
* the id of the container object
* the position of the element in the array
* the value of the element
The field names are passed in a hash that associates a field name with a field descriptor. The field descriptor may be either a hash or a
string. The hash uses the following fields:
* type
* table
* sql
Optional field "type" specifies the type of the elements. If the type is "string"Tangram quotes the values as they are passed to the data-
base. Not specifying a "type" is exactly equivalent to specifying "string".
Optional field "table" sets the name of the table that contains the elements. This defaults to 'C_F', where C is the class of the contain-
ing object and F is the field name.
Optional field "sql" specifies the type that deploy() (see Tangram::Deploy) should use for the column containing the elements. If this
field is not present, the SQL type is derived from the "type" field: if "type" is "string" (or is absent) VARCHAR(255) is used; otherwise,
the "type" field is interpreted as a SQL type.
If the descriptor is a string, it is interpreted as the value of the "type" field and all the other fields take the default value.
