How to fix in laravel 5.2 zizaco entrust:migration class name validation?

问题

I have followed zizac/entrust installation tutorial from GitHub Link and faced with error:

Class name must be a valid object or a string in var/www/html/laravel_test/vendor/zizaco/entrust/src/commands/MigrationCommand.php on line 86

MigrationCommand.php file url : Link

Outut:

php artisan entrust:migration

Tables: roles, role_user, permissions, permission_role
A migration that creates 'roles', 'role_user', 'permissions', 'permission_role' tables will be created in database/migrations directory

Proceed with the migration creation? [Yes|no] (yes/no) [yes]: yes

Creating migration...
PHP Fatal error:  Class name must be a valid object or a string in /var/www/html/laravel_test/vendor/zizaco/entrust/src/commands/MigrationCommand.php on line 86

the command: php artisan vendor:publish was successful.

File : config/entrust.php exist.

I didin't change any options to config/auth.php file same as - auth.php. How to fix it?

回答1:

in vendor/zizaco/entrust/src/commands/MigrationCommand.php on line 86

remove line :

    $usersTable  = Config::get('auth.table');
    $userModel   = Config::get('auth.model');

add line :

$usersTable  = Config::get('auth.providers.users.table');
$userModel   = Config::get('auth.providers.users.model');

and config/auth.php file write provider line as like me :

'providers' => [
    'users' => [
        'driver' => 'eloquent',
        'model' => App\User::class,
        'table' => 'users',
    ],

    // 'users' => [
    //     'driver' => 'database',
    //     'table' => 'users',
    // ],
],

then your problem will solve : happy coding

In vendor/zizaco/entrust/src/commands/MigrationCommand.php on line 86.

Laravel 5.1.* Add Line

$usersTable  = Config::get('auth.table');
$userModel   = Config::get('auth.model');

Laravel 5.2.* Add Line

$usersTable  = Config::get('auth.providers.users.table');
$userModel   = Config::get('auth.providers.users.model');

The accepted answer may fix the problem but it is very bad practice to edit direct vendor files. The following will fix the issue you may be having and will support your app still working if you decide to update Entrust and they fix their codebase.

Add the following lines to config/auth.php underneath:

/*
|--------------------------------------------------------------------------
| User Providers
|--------------------------------------------------------------------------
|
| All authentication drivers have a user provider. This defines how the
| users are actually retrieved out of your database or other storage
| mechanisms used by this application to persist your user's data.
|
| If you have multiple user tables or models you may configure multiple
| sources which represent each model / table. These sources may then
| be assigned to any extra authentication guards you have defined.
|
| Supported: "database", "eloquent"
|
*/

Laravel 5.1 - 5.4

'model' => \App\Models\User::class,
'table' => 'users',

Once Entrust rolls out an update you can remove this or keep it. Up to you.

Try running:

php artisan config:cache

to make sure your application is using fresh config files

EDIT

Ok, now I see, this library want to use:

  $usersTable  = Config::get('auth.table');
  $userModel   = Config::get('auth.model');

but there is no something like this in auth any more.

So as temporary workaround you should probaby add table and model to auth file like so: https://github.com/laravel/laravel/blob/5.1/config/auth.php

and wait until Entrust will be upgraded to remove this
