Requirements

Grails Version: 1.1 and above JDK: 1.5 and above

Installation

grails install-plugin taggable

Usage

Implement the Taggable interface:

import org.grails.taggable.*class Vehicle implements Taggable {
}

Add some tags:

def v = Vehicle.get(1)v.addTag("red")
 .addTag("sporty")
 .addTag("expensive")

Query:

def v = Vehicle.get(1)
println v.tagsdef vehicles = Vehicle.findAllByTag("sporty")
def count = Vehicle.countByTag("sporty")
assert 3 == Vehicle.totalTags
assert ['expensive', 'red','sporty'] == Vehicle.allTags

Tag parsing:

def tags = "red,sporty,expensive"
def v = Vehicle.get(1)v.parseTags(tags)
assert ['expensive', 'red','sporty'] == v.tags
tags = "red/sporty/expensive"
v.parseTags(tags, "/")
assert ['expensive', 'red','sporty'] == v.tags

Customized Table names in Config.groovy:

grails.taggable.tag.table="MY_TAGS"
grails.taggable.tagLink.table="MY_TAG_LINKS"
