NAME

Interchange6::Schema::Result::Tax

TABLE: taxes

DESCRIPTION

The taxes table contains taxes such as sales tax and VAT. Each tax has a unique tax_name but can contain multiple rows for each tax_name to allow for changes in tax rates over time. When there is more than one row for a single tax_name then the valid_from and valid_to periods may not overlap.

ACCESSORS

taxes_id

  data_type: 'integer'
  is_auto_increment: 1
  is_nullable: 0
  sequence: 'taxes_id_seq'

tax_name

  data_type: 'varchar'
  is_nullable: 0
  size: 64

description

  data_type: 'varchar'
  is_nullable: 0
  size: 64

percent

  data_type: 'numeric'
  is_nullable: 0
  size: [7,4]

precision

  data_type: 'integer'
  is_nullable: 0
  default_value: 2

Number of decimal places of precision required. Defaults to 2.

rounding

  data_type: char"
  is_nullable: 1
  size: 1
  default_value: undef

Default rounding is half round up to the precision number of decimal places. To use floor or ceiling set rounding to 'f' or 'c' as appropriate. The rounding value is automatically converted to lower case and any invalid value passed in will cause an exception to be thrown.

valid_from

  data_type: 'date'
  set_on_create: 1
  is_nullable: 0

valid_to

  data_type: 'date'
  is_nullable: 1

country_iso_code

  data_type: 'char'
  is_foreign_key: 1
  is_nullable: 1
  size: 2

states_id

  data_type: 'integer'
  is_foreign_key: 1
  is_nullable: 1

created

  data_type: 'datetime'

METHODS

calculate

Calculate tax

Arguments should be a hash ref of the following arguments:

  • price

    Price of product either inclusive or exclusive of tax - required.

  • tax_included

    Boolean indicating whether price is inclusive of tax or not. Defaults to 0 which means exclusive of tax.

    Will throw an exception if the price us not numeric.

Usage example:

    my $tax = $taxrecord->caclulate({ price => 13.47, tax_included => 1 });

    # with percentage 18 our tax is 2.05

INHERITED METHODS

new

We overload the new method to set default values on certain rows at create time.

sqlt_deploy_hook

Called during table creation to add indexes on the following columns:

  • tax_name

  • valid_from

  • valid_to

INHERITED METHODS

validate

Validity checks that cannot be enforced using primary key, unique or other database methods using Interchange6::Schema::Component::Validation. The validity checks enforce the following rules:

  • Check country_iso_code is valid

  • If both valid_from and valid_to are defined then valid_to must be a later date than valid_from.

  • A single tax_name may appear more than once in the table to allow for changes in tax rates but valid_from/valid_to date ranges must not overlap.
