Copyable adds a copy() function to your model, which you can use to copy (that is, create a duplicate of) a record and any of its hasOne, hasMany, or hasAndBelongsToMany relationships. In the case of hasOne and hasMany, those records are recursively copied as well. For example, if you want to copy a LinkCategory that hasMany Link, all of the Link records will be copied. The copy is fully recursive, meaning that if Link HasMany Comment, then all of those records will be copied as well. In the case of HABTM associations, only the join table rows are copied, not the associated records. The copy() function takes one argument – the ID of the record you wish to copy.

The code is on page two, but the most current version is kept on Github: http://github.com/jamienay/copyable_behavior
Copyable uses Containable to help generate its queries, but don’t worry – it’ll attach Containable if it can’t find it on the model.

A handful of config options:

* recursive: whether to copy hasOne- and hasMany-associated models (default: true)
* habtm: whether to copy hasAndBelongsToMany relationships (default: true)
* stripFields: an array model fields that should ignored when copying (default: id, created, modified, lft, rght)

After attaching Copyable to a model via the $actsAs array – I recommend putting it on AppModel – usage is as simple as:

Download code
// From a controller method
$this->MyModel->copy($id);
 
// From a model method
$this->copy($id);
