简介 详细Laravel5.5执行表迁移命令出现表为空的解决方案_php实例_
今天在使用一个第三方包 laravel-admin 时，出现了这样的错误：SQLSTATE[42000]: Syntax error or access violation: 1103 Incorrect table name '',折腾了好久，终于知道了解决方法，原来是配置文件的缓存没有清理。
一、问题
vagrant@homestead:~/Code/laravel-shop$ php artisan admin:install
错误提示：
In Connection.php line 664:
SQLSTATE[42000]: Syntax error or access violation: 1103 Incorrect table name '' (SQL: create table `` (`id` int uns
igned not null auto_increment primary key, `username` varchar(190) not null, `password` varchar(60) not null, `name
` varchar(255) not null, `avatar` varchar(255) null, `remember_token` varchar(100) null, `created_at` timestamp nul
l, `updated_at` timestamp null) default character set utf8mb4 collate utf8mb4_unicode_ci)
In Connection.php line 452:SQLSTATE[42000]: Syntax error or access violation: 1103 Incorrect table name ''
二、解决方案
database/migrations/2016_01_04_173148_create_admin_table.php
create(config('admin.database.users_table'), function (Blueprint $table) { $table->increments('id'); $table->string('username', 190)->unique(); $table->string('password', 60); $table->string('name'); $table->string('avatar')->nullable(); $table->string('remember_token', 100)->nullable(); $table->timestamps(); }); Schema::connection($connection)->create(config('admin.database.roles_table'), function (Blueprint $table) { $table->increments('id'); $table->string('name', 50)->unique(); $table->string('slug', 50); $table->timestamps(); }); Schema::connection($connection)->create(config('admin.database.permissions_table'), function (Blueprint $table) { $table->increments('id'); $table->string('name', 50)->unique(); $table->string('slug', 50); $table->string('http_method')->nullable(); $table->text('http_path')->nullable(); $table->timestamps(); }); Schema::connection($connection)->create(config('admin.database.menu_table'), function (Blueprint $table) { $table->increments('id'); $table->integer('parent_id')->default(0); $table->integer('order')->default(0); $table->string('title', 50); $table->string('icon', 50); $table->string('uri', 50)->nullable(); $table->timestamps(); }); Schema::connection($connection)->create(config('admin.database.role_users_table'), function (Blueprint $table) { $table->integer('role_id'); $table->integer('user_id'); $table->index(['role_id', 'user_id']); $table->timestamps(); }); Schema::connection($connection)->create(config('admin.database.role_permissions_table'), function (Blueprint $table) { $table->integer('role_id'); $table->integer('permission_id'); $table->index(['role_id', 'permission_id']); $table->timestamps(); }); Schema::connection($connection)->create(config('admin.database.user_permissions_table'), function (Blueprint $table) { $table->integer('user_id'); $table->integer('permission_id'); $table->index(['user_id', 'permission_id']); $table->timestamps(); }); Schema::connection($connection)->create(config('admin.database.role_menu_table'), function (Blueprint $table) { $table->integer('role_id'); $table->integer('menu_id'); $table->index(['role_id', 'menu_id']); $table->timestamps(); }); Schema::connection($connection)->create(config('admin.database.operation_log_table'), function (Blueprint $table) { $table->increments('id'); $table->integer('user_id'); $table->string('path'); $table->string('method', 10); $table->string('ip', 15); $table->text('input'); $table->index('user_id'); $table->timestamps(); }); } /** * Reverse the migrations. * * @return void */ public function down() { $connection = config('admin.database.connection') ?: config('database.default'); Schema::connection($connection)->dropIfExists(config('admin.database.users_table')); Schema::connection($connection)->dropIfExists(config('admin.database.roles_table')); Schema::connection($connection)->dropIfExists(config('admin.database.permissions_table')); Schema::connection($connection)->dropIfExists(config('admin.database.menu_table')); Schema::connection($connection)->dropIfExists(config('admin.database.user_permissions_table')); Schema::connection($connection)->dropIfExists(config('admin.database.role_users_table')); Schema::connection($connection)->dropIfExists(config('admin.database.role_permissions_table')); Schema::connection($connection)->dropIfExists(config('admin.database.role_menu_table')); Schema::connection($connection)->dropIfExists(config('admin.database.operation_log_table')); } } 清除配置文件缓存
vagrant@homestead:~/Code/laravel-shop$ php artisan config:cache
再次执行发布命令，就可以了：
vagrant@homestead:~/Code/laravel-shop$ php artisan admin:install Migrating: 2016_01_04_173148_create_admin_table Migrated: 2016_01_04_173148_create_admin_table Admin directory was created: /app/Admin HomeController file was created: /app/Admin/Controllers/HomeController.php ExampleController file was created: /app/Admin/Controllers/ExampleController.php Bootstrap file was created: /app/Admin/bootstrap.php Routes file was created: /app/Admin/routes.php vagrant@homestead:~/Code/laravel-shop$
