这个名字是源自于Ruby On Rails在那时候的印象，不直接使用MySQL的目的在于让我们可以专注于过程。

1.1.1 创建表

表的概念，类似于在Excel中的表，如果你真实不懂数据库。让我们创建一个athomes的表，为什么是athomes，因为以前在写android程序的时候就叫的是athome，忽略掉这些次要的因素吧。

$ php artisan migrate:make create_athomes_table

打开 app/database/migrations/create_athomes_table.php这里的是由日期和某些东西组成的，修改生成的代码为下面。

use Illuminate\Database\Schema\Blueprint;  
use Illuminate\Database\Migrations\Migration;  

class CreateAthomesTable extends Migration {
    public function up()  
    {  
        Schema::create('athomes', function(Blueprint $table)  
        {  
            $table--->increments('id');  
            $table->float('temperature');  
            $table->float('sensors1');  
            $table->float('sensors2');  
            $table->boolean('led1');  
            $table->timestamps();  
        });  
    }  
    public function down()  
    {  
        Schema::drop('athomes');  
    }  
}

意思大致就是id是自加的，也就是我们在localhost/athome/{id}，当我们创建一个新的数据的时候，会自动加上去，最后一个timestamps批的是时间，会包含创建时间和修改时间。剩下的temperature,sensors1,sensors2是小数，以及只有真和假的led1。

1.1.2 数据库迁移

我们只是写了我们需要的数据的格式而并没有丢到数据库里，

$ php artisan migrate

这个就是我们执行迁移的命令，如果你用phpmyadmin可以直接打开查看，没有的话，可以。

use iot;
select * from athomes;

1.2 创建RESTful

$ php artisan controller:make AthomesController

class AthomesController extends \BaseController {  
    public function index() {}  
    public function create()  {} 
    public function store() {}  
    public function show($id) {}  
    public function edit($id) {}  
    public function update($id) {}  
    public function destroy($id) {} 
}

1.3 Laravel Resources

所以我们只需要专注于创建 create, edit, show, destory 等等。好吧，你可能没有耐心了，但是在修改这个之前我们需要先在 app/model 加个 class

Verb	Path	Action	Route Name
GET	/resource	index	resource.index
GET	/resource/create	create	resource.create
POST	/resource	store	resource.store
GET	/resource/{resource}	show	resource.show
GET	/resource/{resource}/edit	edit	resource.edit
PUT/PATCH	/resource/{resource}	update	resource.update
DELETE	/resource/{resource}	destroy	resource.destroy

class Athomes extends Eloquent {  
    protected $table = 'athomes';  
}

class AthomesController extends \BaseController {
    public $restful=true;
    protected $athome;
    public function __construct(Athomes $athome)
    {
        $this--->athome = $athome ;
     }
    public function index()
    {
        $maxid=Athomes::all();
        return Response::json($maxid);
    }
    public function create()
    {
        $maxid=Athomes::max('id');
        return View::make('athome.create')->with('maxid',$maxid);
    }
    public function store()
    {
        $rules = array(
            'led1'=>'required',
            'sensors1' => 'required|numeric|Min:-50|Max:80',
            'sensors2' => 'required|numeric|Min:-50|Max:80',
            'temperature' => 'required|numeric|Min:-50|Max:80'
        );
        $validator = Validator::make(Input::all(), $rules);
        if ($validator->fails()) {
            return Redirect::to('athome/create')
                ->withErrors($validator)
                ->withInput(Input::except('password'));
        } else {
            $nerd = new Athomes;
            $nerd->sensors1       = Input::get('sensors1');
            $nerd->sensors2       = Input::get('sensors2');
            $nerd->temperature    = Input::get('temperature');
            $nerd->led1           = Input::get('led1');
            $nerd->save();
            Session::flash('message', 'Successfully created athome!');
            return Redirect::to('athome');
        }
    }
    public function show($id)
    {
        $myid=Athomes::find($id);
        $maxid=Athomes::where('id','=',$id)
                        ->select('id','temperature','sensors1','sensors2','led1')
                        ->get();
        return Response::json($maxid);
    }
    public function edit($id)
    {
        $athome = Athomes::find($id);
        return View::make('athome.edit')
            ->with('athome', $athome);
    }
    public function update($id)
    {
        $rules = array(
            'led1'=>'required|',
            'sensors1' => 'required|numeric|Min:-50|Max:80',
            'sensors2' => 'required|numeric|Min:-50|Max:80',
            'temperature' => 'required|numeric|Min:-50|Max:80'
        );
        $validator = Validator::make(Input::all(), $rules);
        if ($validator->fails()) {
            return Redirect::to('athome/' . $id . '/edit')
                ->withErrors($validator);
        } else {
            $nerd = Athomes::find($id);
            $nerd->sensors1       = Input::get('sensors1');
            $nerd->sensors2       = Input::get('sensors2');
            $nerd->temperature    = Input::get('temperature');
            $nerd->led1           = Input::get('led1');
            $nerd->save();
            Session::flash('message', 'Successfully created athome!');
            return Redirect::to('athome');
        }
    }
    public function destroy($id)
    {
        $athome = Athomes::find($id);
        $athome->delete();
        if(is_null($athome))
        {
             return Response::json('Todo not found', 404);
        }
        Session::flash('message', 'Successfully deleted the nerd!');
        return Redirect::to('athome');
    }
}

下面这部分来自于之前的博客，这里就不多加论述了。这个也就是我们要的模板，

1.3.1 修改Create()

public function create()
{
    $maxid=Athomes::max('id');
    return View::make('athome.create')->with('maxid',$maxid);
}

这里需要在app/views/创建一个athome里面创建一个create.blade.php，至于maxid，暂时还不需要，后面会用到show。如果只需要模板，可以简化为

public function create()
{
    return View::make('athome.create');
}

1.3.2 创建表单

1.3.2.1 创建表单之前

<link rel="stylesheet" type="text/css" href="<?= url('css/bootstrap.min.css') ?>" />
<link rel="stylesheet" type="text/css" href="<?= url('css/bootstrap-select.min.css') ?>" />

<script type="text/javascript" src="<?= url('js/jquery.min.js')?>"></script>
<script type="text/javascript" src="<?= url('js/bootstrap.min.js') ?>"></script>
<script type="text/javascript" src="<?= url('js/bootstrap-select.min.js') ?>"></script>
<script>
$('.selectpicker').selectpicker();
</script>

1.3.2.2 创建表单

这里用到的是之前提到的那个作者写下的，稍微修改了一下。

<div class="row-fluid">
  {{ HTML::ul($errors->all()) }}
  {{ Form::open(array('url' => 'athome')) }}
     <div class="form-group">
          {{ Form::label('led1', '开关1') }}
          {{ Form::select('led1',array('关','开'),$selected=NULL,array('class'=>'selectpicker')) }}
      </div>
      <div class="form-group">
          {{ Form::label('sensors1', 'sensors1') }}
          {{ Form::text('sensors1', Input::old('sensors1'), array('class' => 'form-control')) }}
      </div>
      <div class="form-group">
          {{ Form::label('sensors2', 'sensors2') }}
          {{ Form::text('sensors2', Input::old('sensors2'), array('class' => 'form-control')) }}
      </div>
      <div class="form-group">
          {{ Form::label('temperature', 'temperature') }}
          {{ Form::text('temperature', Input::old('temperature'), array('class' => 'form-control')) }}
      </div>
      {{ Form::submit('Create!', array('class' => 'btn btn-primary')) }}
  {{ Form::close() }}
  </div>

开关一开始打算用 checkbox，加上 bootstrap-switch 实现 ON OFF 弱弱地觉得还是没掌握好的节奏，所以最后用 select 来实现。

return Redirect::to('athome');

也就是添加完后，重定向到首页查看，最后例子给出的 create 如下

public function store()
{
    $rules = array(
        'led1'=>'required',
        'sensors1' => 'required|numeric|Min:-50|Max:80',
        'sensors2' => 'required|numeric|Min:-50|Max:80',
        'temperature' => 'required|numeric|Min:-50|Max:80'
    );
    $validator = Validator::make(Input::all(), $rules);
    if ($validator->fails()) {
        return Redirect::to('athome/create')
            ->withErrors($validator);
    } else {
        // store
        $nerd = new Athomes;
        $nerd->sensors1       = Input::get('sensors1');
        $nerd->sensors2       = Input::get('sensors2');
        $nerd->temperature    = Input::get('temperature');
        $nerd->led1            = Input::get('led1');
        $nerd->save();
        Session::flash('message', 'Successfully created athome!');
        return Redirect::to('athome');
    }
}

1.3.3 编辑模板
