在开发mvc项目时,models都是第一步。
下面就从建模开始。
1.实体关系图,
由于不知道php有什么好的建模工具,这里我用的vs ado.net实体模型数据建模
下面开始laravel编码,编码之前首先得配置数据库连接,在app/config/database.php文件
\'mysql\' => array( \'driver\' => \'mysql\', \'read\' => array( \'host\' => \'127.0.0.1:3306\', ), \'write\' => array( \'host\' => \'127.0.0.1:3306\' ), \'database\' => \'test\', \'username\' => \'root\', \'password\' => \'root\', \'charset\' => \'utf8\', \'collation\' => \'utf8_unicode_ci\', \'prefix\' => \'\', ),
配置好之后,需要用到artisan工具,这是一个php命令工具在laravel目录中
首先需要要通过artisan建立一个迁移 migrate ,这点和asp.net mvc几乎是一模一样
在laravel目录中 shfit+右键打开命令窗口 输入artisan migrate:make create_XXXX会在app/database/migrations文件下生成一个带时间戳前缀的迁移文件
代码:
<?php
use Illuminate\\Database\\Schema\\Blueprint;
use Illuminate\\Database\\Migrations\\Migration;
class CreateTablenameTable extends Migration {
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
}
}
看到这里有entityframework 迁移经验的基本上发现这是出奇的相似啊。
接下来就是创建我们的实体结构,laravel 的结构生成器可以参考http://v4.golaravel.com/docs/4.1/schema
<?php
use Illuminate\\Database\\Schema\\Blueprint;
use Illuminate\\Database\\Migrations\\Migration;
class CreateTablenameTable extends Migration {
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create(\'posts\', function(Blueprint $table) {
$table->increments(\'id\');
$table->unsignedInteger(\'user_id\');
$table->string(\'title\');
$table->string(\'read_more\');
$table->text(\'content\');
$table->unsignedInteger(\'comment_count\');
$table->timestamps();
});
Schema::create(\'comments\', function(Blueprint $table) {
$table->increments(\'id\');
$table->unsignedInteger(\'post_id\');
$table->string(\'commenter\');
$table->string(\'email\');
$table->text(\'comment\');
$table->boolean(\'approved\');
$table->timestamps();
});
Schema::table(\'users\', function (Blueprint $table) {
$table->create();
$table->increments(\'id\');
$table->string(\'username\');
$table->string(\'password\');
$table->string(\'email\');
$table->string(\'remember_token\', 100)->nullable();
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::drop(\'posts\');
Schema::drop(\'comments\');
Schema::drop(\'users\');
}
}
继续在上面的命令窗口输入php artisan migrate 将执行迁移
