TableDef - Table data definition

VERSION

This document describes version 1.0.5 of TableDef (from Perl distribution TableDef), released on 2014-09-20.

SPECIFICATION VERSION

 1

ABSTRACT

This document describes TableDef, a way to define table data.

SPECIFICATION

In this document, hashes are written in JSON or pseudo-JSON (e.g. contains ellipsis ... or JavaScript-style comments // ...).

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL "NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119.

A TableDef spec is written in DefHash. It can be used to describe the structure of a relational database table, a CSV file, or an array of hashes. Tools can be written to convert a TableDef hash to SQL's CREATE TABLE statement, or to utilize information in the TableDef hash to format an HTML table, to view a DB grid on the web browser, etc.

Properties

summary => str

From DefHash. Table summary.

description => str

From DefHash. Table longer description.

tags => array

From DefHash.

fields => hash

A hash, where the keys are field names and the values field specification. See "FIELD SPECIFICATION".

pk => str | array

Specify the primary key for the table. Either a string containing a single field name, or an array of field names (for multi-field key).

FIELD SPECIFICATION

A DefHash.

Properties

schema* => str | array

Sah schema. This property is required.

summary => str

From DefHash. Field summary.

description => str

From DefHash. Field longer description.

tags => array

From DefHash.

pos => int

Specify the order of field. Must start from 0 and be contiguous.

req => bool (default: 0)

Whether this field is mandatory to be present. If 0, then function can choose to omit the field.

sortable => bool (default: 1)

Specify whether this field can be sorted.

filterable => bool (default: 1)

Specify whether this field can be used as a filter.

unique => bool

Specify whether this field must contain unique values.

include_by_default => bool (default: 1)

This specifies that this field should be shown or included on "default view". What default view is will depend on the context or implementation. Usually you can set this to 0 if the field content is too long or wide. For example, in Perl module Perinci::Sub::Gen::AccessTable, if you give detail => 1 to the generated function, it will include all fields except fields that has this property set to 0. To include such fields, you'll need to explicitly issue with.FIELDNAME => 1.
