Upgrade Guide 27
Once you have updated the file with a fresh copy, set your authentication configuration options
to their desired value based on your old configuration file. If you were using the typical, Eloquent
based authentication services available in Laravel 5.1, most values should remain the same.
Take special note of the passwords.users.email configuration option in the new auth.php configuration
file and verify that the view path matches the actual view path for your application, as the
default path to this view was changed in Laravel 5.2. If the default value in the new configuration
file does not match your existing view, update the configuration option.
Contracts
If you are implementing the Illuminate\Contracts\Auth\Authenticatable contract but are not
using the Authenticatable trait, you should add a new getAuthIdentifierName method to your
contract implementation. Typically, this method will return the column name of the “primary key”
of your authenticatable entity. For example: id.
This is unlikely to affect your application unless you were manually implementing this interface.
Custom Drivers
If you are using the Auth::extend method to define a custom method of retrieving users, you should
now use Auth::provider to define your custom user provider. Once you have defined the custom
provider, you may configure it in the providers array of your new auth.php configuration file.
For more information on custom authentication providers, consult the full authentication documentation.
Redirection
The loginPath() method has been removed from Illuminate\Foundation\Auth\AuthenticatesUsers,
so placing a $loginPath variable in your AuthController is no longer required. By default, the trait
will always redirect users back to their previous location on authentication errors.
Authorization
The Illuminate\Auth\Access\UnauthorizedException has been renamed to Illuminate\Auth\Access\Authoriza
This is unlikely to affect your application if you are not manually catching this exception.
Collections
Eloquent Base Collections
The Eloquent collection instance now returns a base Collection (Illuminate\Support\Collection)
for the following methods: pluck, keys, zip, collapse, flatten, flip.
