Authorization Contexts

There are also times where you need to validate custom conditions and block access to certain areas. This way, you can implement your own custom security logic and leverage cbSecurity for blockage. You will accomplish this via the secureWhen() method. If the context evaluates to true then it will throw a NotAuthorized exception for you.

{% hint style="info" %} Remember, if the context is TRUE, then it throws the exception. {% endhint %}

secureWhen( context, [errorMessage] )

The context can be a closure/lambda/udf or a boolean evaluation:

// Using as a closure/lambda
cbSecurity.secureWhen( ( user ) => !user.isConfirmed() )
cbSecurity.secureWhen( ( user ) => !oEntry.canPublish( user ) )

// Using a boolean evaluation
cbSecurity.secureWhen( cbSecurity.none( "AUTHOR_ADMIN" ) && !cbSecurity.sameUser( oAuthor )  )
cbSecurity.whenNone( "AUTHOR_ADMIN", ( user ) => relocate() );

The closure/udf will receive the currently authenticated user as the first argument.

( user ) => {}
function( user );

You can also use the message argument to send your own message to the exception that's throw.
