向多个表添加数据 (laravel 4)

Question

我想同时在三个不同的table中添加插入数据。但是在第一个 table 中插入数据后，我需要获取该 ID 并继续使用它在其他两个 table 中插入数据。这些是申请人table、语言table（每个申请人可能会不止一种语言）和技能table（也是一种或多种）。

下面是我一直在尝试的代码：

型号：

class Apply extends Eloquent {

protected $table = 'application';
protected $fillable = ['user_id', 'gender', 'dob', 'ic', 'marriage_status', 'phone', 'city', 'street', 'course', 'university',
    'academic_degree', 'uni_start_date', 'uni_end_date', 'addinfo', 'working_company', 'position', 'start_date', 'end_date', 'reason'];

public function lang() {
    return $this->hasMany('Lang');
}
}

class Lang extends Eloquent 
{
    protected $table = 'language';

public function apply(){
    return $this->belongsTo('Apply');
}
}

class Skills extends Eloquent 
{
    protected $table = 'skills';

public function apply(){
    return $this->belongsTo('Apply');
}
}

控制器：

public function createcv() {
    $input = Input::all();
    $rules = array('ic' => 'required',
        'phone' => 'required',
        'course' => 'required');
    $v = Validator::make($input, $rules);

    if ($v->passes()) {
        $apply = Apply::create(array('user_id' => Auth::user()->id, 'gender' => $input['gender'],
                    'dob' => $input['dob'], 'ic' => $input['ic'], 'marriage_status' => $input['mstatus'],
                    'phone' => $input['phone'], 'city' => $input['city'], 'street' => $input['street'],
                    'course' => $input['course'], 'university' => $input['institution'],
                    'academic_degree' => $input['adegree'], 'uni_start_date' => $input['uni-startdate'],
                    'uni_end_date' => $input['uni-enddate'], 'addinfo' => $input['addinfo'],
                    'working_company' => $input['jobinstitution'], 'position' => $input['jobposition'],
                    'start_date' => $input['startdate'], 'end_date' => $input['enddate'], 'reason' => $input['reason']));
        $apply->save();

        $app_id = $apply->id;
        $lang = Lang::create(array('app_id' => $app_id, 'lang' => $input['lang1'],
                    'reading' => $input['read1'], 'writing' => $input['write1'],
                    'speaking' => $input['speak1'], 'institution' => $input['inst1']
        ));
        $lang->save();

        $skills = Skills::create(array('app_id' => $app_id, 'prog_name' => $input['prog1'],
                    'level' => $input['level1'], 'institution' => $input['instprog1']));
        $skills->save();

        return Redirect::to('home');
    } else {
        return Redirect::to('create-cv')->withInput()->withErrors($v);
    }
}

Answer 1

如果你需要一个record id来存储其他的，这些不能同时保存，因为你保存数据的时候就是你可以检索id的时候。

当您调用模型的 save 方法时，您可以检索数据库中记录的 id，如果您的数据具有相同的键（$key => $value）您可以使用创建方法的列的名称。

来自 Laravel 页：

You may also use the create method to save a new model in a single line. The inserted model instance will be returned to you from the method. However, before doing so, you will need to specify either a fillable or guarded attribute on the model, as all Eloquent models protect against mass-assignment.

Using The Model Create Method
// Create a new user in the database...
$user = User::create(array('name' => 'John'));

// Retrieve the user by the attributes, or create it if it doesn't exist...
$user = User::firstOrCreate(array('name' => 'John'));

// Retrieve the user by the attributes, or instantiate a new instance...
$user = User::firstOrNew(array('name' => 'John'));

因此您的代码将如下所示：

$apply = new Apply();
...
$apply->save();
$id_of_your_apply = $apply->id;

https://laravel.com/docs/4.2/eloquent#insert-update-delete

public function createcv(){
    $input = Input::all();

    $rules = array('ic' => 'required',
        'phone' => 'required',
        'course' => 'required');
    $v = Validator::make($input, $rules);

    if ($v->passes()) {
        $apply = Apply::create(array('user_id' => Auth::user()->id,'gender' => $input['gender'], 'dob' => $input['dob'], 'ic' => $input['ic'], 'marriage_status' => $input['mstatus'], 'phone' => $input['phone'],'city' => $input['city'],'street'=> $input['street'], 'course' => $input['course'], 'university' => $input['institution'], 'academic_degree' => $input['adegree'],'uni_start_date' => $input['uni-startdate'], 'uni_end_date' => $input['uni-enddate'],'addinfo' => $input['addinfo'], 'working_company' => $input['jobinstitution'],'position' => $input['jobposition'], 'start_date' => $input['startdate'],'end_date' => $input['enddate'], 'reason' => $input['reason']));
        $apply->save();

        **$app_id = $apply->id;**

        $lang = Lang::create(array('app_id' => $app_id,'lang' => $input['lang1'],
           'reading' => $input['read1'], 'writing' => $input['write1'], 
            'speaking' => $input['speak1'],'institution' => $input['inst1']
            ));
        $lang->save();

        $skills = Skills::create(array('app_id' => $app_id,'prog_name' => $input['prog1'], 'level' => $input['level1'], 'institution' => $input['inst1']));
        $skills->save();

        return Redirect::to('home');
}
else {
        return Redirect::to('create-cv')->withInput()->withErrors($v);
    }
}

研究代码后，我发现我使用了 Laravel 关键字 "Lang"，laravel 不允许您使用该关键字。还有许多其他关键字，例如：不能使用的 Lang、Events 等。此代码适用于将数据添加到多个表 (laravel 4)
