问题描述
我正在尝试制作以下教程:https://medium.com/on-coding/e8d93c9ce0e2
I'm trying to make following tutorial: https://medium.com/on-coding/e8d93c9ce0e2
当谈到运行时:
php artisan migrate
我收到以下错误:
[Exception]
SQLSTATE[42S02]: Base table or view not found: 1146 Table 'laravel.user' doesn't
exist (SQL: alter table `user` add `id` int unsigned not null auto_increment prim
ary key, add `username` varchar(255) null, add `password` varchar(255) null, add
`email` varchar(255) null, add `created_at` datetime null, add `updated_at` datet
ime null) (Bindings: array (
))
数据库连接正常，迁移表创建成功.如您在错误消息中所见，数据库名称已更改.
Database connection is working, the migrations table was created successfully. Database name was changed as you can see in the error message.
对我来说很奇怪的是，它试图改变表——它不存在——而不是创建它.
Whats quite strange to me, is that it tries to alter the table - which doesn't exists - and not to create it.
这是我的其他文件，例如 UserModel、Seeder、Miggation 和 DB Config.
Here are my other files, like UserModel, Seeder, Migtation and DB Config.
创建用户表:
<?php
use IlluminateDatabaseSchemaBlueprint;
use IlluminateDatabaseMigrationsMigration;
class CreateUserTable extends Migration {
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::table('user', function(Blueprint $table)
{
$table->increments("id");
$table
->string("username")
->nullable()
->default(null);
$table
->string("password")
->nullable()
->default(null);
$table
->string("email")
->nullable()
->default(null);
$table
->dateTime("created_at")
->nullable()
->default(null);
$table
->dateTime("updated_at")
->nullable()
->default(null);
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::table('user', function(Blueprint $table)
{
Schema::dropIfExists("user");
});
}
}
用户模型:
use IlluminateAuthUserInterface;
use IlluminateAuthRemindersRemindableInterface;
class User extends Eloquent implements UserInterface, RemindableInterface {
/**
* The database table used by the model.
*
* @var string
*/
protected $table = 'user';
/**
* The attributes excluded from the model's JSON form.
*
* @var array
*/
protected $hidden = array('password');
/**
* Get the unique identifier for the user.
*
* @return mixed
*/
public function getAuthIdentifier()
{
return $this->getKey();
}
/**
* Get the password for the user.
*
* @return string
*/
public function getAuthPassword()
{
return $this->password;
}
/**
* Get the e-mail address where password reminders are sent.
*
* @return string
*/
public function getReminderEmail()
{
return $this->email;
}
}
用户种子:
class UserSeeder extends DatabaseSeeder
{
public function run()
{
$users = [
[
"username" => "ihkawiss",
"password" => Hash::make("123456"),
"email" => "ihkawiss@domain.com"
]
];
foreach ($users as $user)
{
User::create($user);
}
}
}
数据库播种机:
class DatabaseSeeder extends Seeder {
/**
* Run the database seeds.
*
* @return void
*/
public function run()
{
Eloquent::unguard();
$this->call('UserSeeder');
}
}
数据库配置:
return array(
/*

|
| By default, database results will be returned as instances of the PHP
| stdClass object; however, you may desire to retrieve records in an

'redis' => array(
'cluster' => true,
'default' => array(
'host' => '127.0.0.1',
'port' => 6379,
'database' => 0,
),

);
希望有人可以在这里给我一个提示.
Hope somebody can give me a hint here.

推荐答案
在你的 CreateUserTable 迁移文件中，你必须使用 而不是 .Schema::tableSchema::create
In your CreateUserTable migration file, instead of Schema::table you have to use Schema::create.
Schema::table 用于更改现有表，Schema::create 用于创建新表.
The Schema::table is used to alter an existing table and the Schema::create is used to create new table.
查看文档:
- http://laravel.com/docs/schema#creating-and-dropping-tables
- http://laravel.com/docs/schema#adding-columns
所以您的用户迁移将是:
So your user migration will be:
<?php
use IlluminateDatabaseSchemaBlueprint;
use IlluminateDatabaseMigrationsMigration;
class CreateUserTable extends Migration {
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('user', function(Blueprint $table) {
{
$table->increments("id",true);
$table->string("username")->nullable()->default(null);
$table->string("password")->nullable()->default(null);
$table->string("email")->nullable()->default(null);
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists("user");
}
}
