h1. Lift Stamped

  

These traits let you extend your MetaMapper-models to log every change

made by users (and the belonging customers). Tested on liftweb 1.1-M7.

  

  

h2. What it does do

* logging *which user/customer* changed *which record* on *which class*

* skip logging (initial user creation, for background-job purpose)

* adds reverse associations so your record has a "logs" method  

  

  

h2. What it doesn't do (yet)

* logging of *what* changed

* reverting records according to *what* was changed

* reverse associations for the Singleton to get every log associated with that model  

h2. Traits for the class

* CustomerFields: adds a customer-object to the model

* ActivateFields: adds an active-boolean to the model (with seperate logging)

* ActionLogs: adds reverse associations to records (not the singleton)  

h2. Traits for the singleton

* Stamped: stamps any changes done to records in that model

* Activatable: logging for ActivateFields

h2. Stamping a model

bc. class MyModel extends LongKeyedMapper[MyModel]

	with IdPK

	with CustomerFields[MyModel]

	with ActionLogs[MyModel]

	with ActivateFields[MyModel] {

bc. object MyModel extends MyModel with LongKeyedMetaMapper[MyModel]

	with Stamped[MyModel] with Activatable[MyModel]

h2. Initial user creation with logging skipped  

  

In Boot.scala add this:

bc. if (Customer.findAll.length == 0) {

	/* Customer creation */

        Customer.skipLogging = true

        val c = new Customer

        c.name("First Customer").save

        Customer.skipLogging = false

	/* User creation */

	User.skipLogging = true

        val u = new User

        u.customer(c).

        firstName("First").

        lastName("User").

        email("[email protected]").

        password("s0m3th1ngs3cur3").

        validated(true).save

        User.skipLogging = false

}

h2. Read the sourcecode!

Really, it's open source for a reason. ;)
