How to use a service class in a controller class?

Question

I'm trying to integrate this amazing calendar in my project. I get trouble with the service thing. I'm using this kind of structure:

application/
    modules/
        agenda/
            controllers/
                CalendarController.php
            models/
            services/
                CalendarService.php
            views/
                filters/
                helpers/
                scripts/
                calendar/
                    view-calendar.php
    module2/
    module3/

I route this in my application.ini this way:

resources.router.routes.agenda.route = /apps/agenda/
resources.router.routes.agenda.defaults.module = agenda
resources.router.routes.agenda.defaults.controller = calendar
resources.router.routes.agenda.defaults.action = view

I pointed my browser on, and I obtained this message:

Message: Invalid controller class ("Agenda_CalendarController") 

I fixed it with my Agenda_ suffix and refreshed my browser. Obtained this:

Message: Controller "Agenda_CalendarController" is not an instance of Zend_Controller_Action_Interface

So I instanced it with "extends Zend_Controller_Action". Obtained this: :-)

Fatal error: Class 'Service_Calendar' not found in /home/[PATH TO MY APP FOLDER]/application/modules/agenda/controllers/CalendarController.php on line 30

I can't figure out what's going wrong. Someone have a hint or two for me :-)

Note: I do not know if that means anything, but I use NetBeans and if I press CTRL while hover a class method of service in the controller class; related popup informations are correct.

Solution: Thanks guys, You gave me the path to go further. My modules bootstraping wasn't set properly. with your hints I found this post from Bob Allen, where he describes the same problem.

When you know what you're searching for... :-)

Thanks, my problem is fixed and I know a bit more!

Answer 1

The naming convention for a controller isn't the same for model/service/view etc., in the sense that you needn't prepend the type in the filename, as you would with a controller. They must follow the basic autoloading name-to-path schema.

So, the declaration for you service would be: Agenda_Service_CalendarService, because that maps to modules/agenda/services/CalendarService.php (note the inflection - from the services folder to the _Service_ singular - that's ZF working and it happens for models, too).

Also make sure you've properly initialized the module (having its own Bootstrap.php file, set up in application.ini).

PS: NetBeans knows where your class is, because it scanned the files and saw the declaration, not the logical inclusion of that class.
