Laravel unexpected error "class user contains 3 abstract methods..."

Solution 1:

Ah found it.

Its apparently documented Laravel Update.

You can check Laravel docs to fix your issues:

"First, add a new, nullable remember_token of VARCHAR(100), TEXT, or equivalent to your users table.

Next, if you are using the Eloquent authentication driver, update your User class with the following three methods:

public function getRememberToken()
{
    return $this->remember_token;
}

public function setRememberToken($value)
{
    $this->remember_token = $value;
}

public function getRememberTokenName()
{
    return 'remember_token';
}

"

See http://laravel.com/docs/upgrade for further details.

Solution 2:

I'm not a pro at implementing PHP Interfaces, but I believe you need to include all methods of UserInterface and RemindableInterface in your User class (since it implements them). Otherwise, the class is "abstract" and must be defined as such.

By my knowledge, a PHP interface is a set of guidelines that a class must follow. For instance, you can have a general interface for a specific database table. It would include definition of methods like getRow(), insertRow(), deleteRow(), updateColumn(), etc. Then you can use this interface to make multiple different classes for different database types (MySQL, PostgreSQL, Redis), but they must all follow the rules of the interface. This makes migration easier, since you know no matter which database driver you are using to retrieve data from a table it will always implement the same methods defined in your interface (in other words, abstracting the database-specific logic from the class).

3 possible fixes, as far as I know:

abstract class User extends Eloquent implements UserInterface, RemindableInterface
{
}

class User extends Eloquent
{
}

class User extends Eloquent implements UserInterface, RemindableInterface
{
     // include all methods from UserInterFace and RemindableInterface
}

I think #2 is best for you, since if your class doesn't implement all methods from UserInterface and RemindableInterface why would you need to say it does.

Solution 3:

This is an update problem. Laravel force us to update the User.php model with the following code to fix this problem.

Note: All existing "remember me" sessions will be invalidated by this change, so all users will be forced to re-authenticate with your application.

public function getRememberToken()
{
    return $this->remember_token;   
}

public function setRememberToken($value)
{
    $this->remember_token = $value;
} 

public function getRememberTokenName()
{
    return 'remember_token';
}
