Fat-Free with Cortex Models and REST

I'm trying to use FatFree and Cortex plugin within my REST API. I seem to have some challenges, at first I was challenged with the namespaces, which I was trying to find how to solve that. And then once I set that up, it was giving issues with method get() already existed. I later tried to not use namespaces to see if that would help, but continued with errors.

I am hoping to get some clarification on how to setup Cortex + F3 + REST API and having auto mapping routes. What am I doing wrong on setting up the model for Cortex? Namespaces doesn't really matter, if I use them or not (personally). Just would like it to work.

My Autoloader is

$f3->set('AUTOLOAD','app/controllers/;app/models/');

Here is my file setup

Solution

Multiple issues here.

don't mix different upper-case lower-case namings for files and folder or the autoload will not find it.. use file path App/Controllers/Contacts.php when your namespace is \App\Controllers\Contacts or name all files and folder in lower-case.. but don't mix them
When you set your namespace at \App\Controllers, \App\Models, etc. your AUTOLOAD setting should only be '' to use the project root. If you set AUTOLOAD to app/, then your namespace begins at this folder, so it's just namespace Controllers. Same for Models
When you are within a namespace, you have to add a leading \ to your namespace of other files, so within namespace \App\Controllers in you must use new \App\Models\ContactsModel .. if you only write new App\Models\ContactsModel, it'll look for a file at app/controllers/app/models/contactsmodel.php

I would suggest:

change folder names to: app/Models and app/Controller, etc
leave file names for classes the same as the class name so class ContactsModel -> ContactsModel.php
set AUTOLOAD to app/ only
use namespaces like folders within app/, so ContactsModel -> namespace Model; and Contacts -> namespace Controllers
