Yii2 Database procedure extension

This extension provides layer for working with database procedures/views in Yii2 application.

It is created to work well with Yii2 applications, but with right configuration it could be used with other frameworks too.

REQUIREMENTS

The minimum requirement by this project:

• PHP 7.2.0.

Procedures

In Application every procedure have its own model. Procedure model must implement interface damidev\dbprocedures\models\IProcedure. For easier work with procedures, we created abstract class damidev\dbprocedures\models\Procedure. This class implements IProcedure, calls events, defines scenarios.

Every procedure model must define Procedure::call() and at least call method Procedure::execute(). Its becouse procedures returns single or many objects, this information know only programmer.

So for single result procedure we implement damidev\dbprocedures\models\SimpleProcedure. For multiple rows we implement damidev\dbprocedures\models\MultiProcedure. There is damidev\dbprocedures\models\PagnatedProcedure that provides pagination logic on MultiProcedure.

Procedure lifecycle

When Procedure::call() is invoked

-> call()
-> call execute(queryOne|queryAll)
    -> set scenario to Procedure::PROCEDURE_CALL
    -> call event beforeCall()               -- used to modify (or validate) input attributes
    -> db procedure exec
    -> set scenario to previous one
    -> call event afterCall($result)         -- used to modify procedure result
<- $result

When Procedure::callCount() is invoked

-> callCount()
    -> set scenario to Procedure::PROCEDURE_COUNT
    -> db count procedure exec
    -> set scenario to previous one
<- $count

Procedure actions

Extension provides ready-to-use standalone actions, that makes creating for example REST API lot of easier.

There is damidev\dbprocedures\actions\SimpleProcedureAction for view/detail actions and damidev\dbprocedures\actions\PaginatedProcedureAction for index/list/paginated actions.
