Laravel5学生成绩管理系统-01-安装-建表-填充数据
注：以下笔记都是按照此博文进行开发学习，开发环境为Mac 。
一、从github上克隆项目到本地
git clone https://github.com/RryLee/StuGradeWithLaravel5.git
二、切换到本地项目目录下，安装composer
MacdeMacBook-Pro-3:~ mac$ cd Desktop MacdeMacBook-Pro-3:StuGradeWithLaravel5 mac$ curl -sS https://getcomposer.org/installer | php All settings correct for using Composer Downloading 1.0.1... Composer successfully installed to: /Users/mac/Desktop/StuGradeWithLaravel5/composer.phar Use it: php composer.phar
// 可以将上边的命令放入到 bin目录下，方便后边不用每次都输入上次的命令
MacdeMacBook-Pro-3:StuGradeWithLaravel5 mac$ sudo mv composer.phar /usr/bin/composer MacdeMacBook-Pro-3:StuGradeWithLaravel5 mac$
// 更新composer
MacdeMacBook-Pro-3:StuGradeWithLaravel5 mac$ composer update
更新出现这样的问题，-_-!!!
MacdeMacBook-Pro-3:StuGradeWithLaravel5 mac$ composer update
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.
Problem 1
- laravel/framework v5.0.9 requires ext-mcrypt * -> the requested PHP extension mcrypt is missing from your system.
看起来是php没有安装mcrypt扩展，如何安装mcrypt具体可以参考我的另一篇博文：
Mac下安装PHP的mcrypt扩展的方法
三、创建表和创建数据
桌面进入：
MacdeMacBook-Pro-3:~ mac$ cd Desktop/StuGrade
MacdeMacBook-Pro-3:StuGrade mac$
利用Migration创建一个用户详细表
生成一个表，注意表名一般为复数 --create=users_info 为后边的标示
MacdeMacBook-Pro-3:laravel mac$ php artisan make:migration create_users_info_table --create=users_info Created Migration: 2016_04_23_131412_create_users_info_table MacdeMacBook-Pro-3:laravel mac$
然后在database/migrations生成的迁移文件中，添加相关的字段：
2016_04_23_131412_create_users_info_table.php
<?php
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateUsersTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->integer('id')->unique()->unsigned(); // 学号唯一，取正数
$table->string('name');
$table->string('password');
$table->string('phone')->default('');
$table->string('sex')->default('');
$table->string('email')->default('');
$table->string('pro_class')->default('');
$table->boolean('is_admin')->default(0);
$table->rememberToken();
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::drop('users');
}
}
最后，执行 php artisan migrate命令，在数据库中生成表users_info
MacdeMacBook-Pro-3:laravel mac$ php artisan migrate Migrated: 2016_04_23_132854_create_users_info_table
应用artisan命令给users_info表填充数据：
用命令生成填充表UserInfoTableSeeder
MacdeMacBook-Pro-3:~ mac$ cd Desktop/laravel MacdeMacBook-Pro-3:laravel mac$ php artisan make:seeder UsersInfoTableSeeder Seeder created successfully. MacdeMacBook-Pro-3:laravel mac$
如下所示，我们将修改 Laravel 预先生成好的 UserInfoTableSeeder 类来给 run 方法添加一段可在数据库添加数据的语法：
<?php
use Illuminate\Database\Seeder;
use App\UsersInfo;
use App\Grade;
class UsersInfoTableSeeder extends Seeder
{
/**
* Run the database seeds.
*
* @return void
*/
public function run()
{
DB::table('users_info')->delete();
UsersInfo::create([
'id' => 2010300001,
'name' => '周润发',
'password' => Hash::make('2010300001'),
]);
UsersInfo::create([
'id' => 2010300002,
'name' => '周星驰',
'password' => Hash::make('2010300002'),
]);
UsersInfo::create([
'id' => 2010300003,
'name' => '成龙',
'password' => Hash::make('2010300003'),
]);
UsersInfo::create([
'id' => 2010300004,
'name' => '张曼玉',
'password' => Hash::make('2010300004'),
]);
UsersInfo::create([
'id' => 2010300005,
'name' => '林青霞',
'password' => Hash::make('2010300005'),
]);
}
}
在 DatabaseSeeder 类中，你可以使用 call 方法来运行其它的 seed 类。为避免发生单个 seeder 类变得太大的情况，可使用 call方法来将数据填充拆分成多个文件。只需简单传递你想要运行的 seeder 类名称即可：
<?php
use Illuminate\Database\Seeder;
use Illuminate\Database\Eloquent\Model;
class DatabaseSeeder extends Seeder
{
/**
* Run the database seeds.
*
* @return void
*/
public function run()
{
Model::unguard();
// 执行插入用户详细数据
$this->call(UsersInfoTableSeeder::class);
Model::reguard();
}
}
运行数据填充：
MacdeMacBook-Pro-3:laravel mac$ composer dump-autoload Generating autoload files MacdeMacBook-Pro-3:laravel mac$ php artisan db:seed Seeded: UsersInfoTableSeeder
查看users_info表，数据填充OK：
