Laravel 4创建用于添加关系记录的表格

Question

I have created very basic Model. I have persons table and emails table. Also I have create a link in the persons/show.blade.php ("Add mail"). My models are

class Person extends Eloquent {

    protected $table = 'persons';

    public function email()
    {
        return $this->HasMany('Email');
    }

}

and

class Email extends Eloquent {

    protected $table = 'emails';

    public static $rules = array(
        'email'=>'required|unique:emails'       
    );

    public function person()
    {
        return $this->belongsTo('Person');
    }
}

How can I pass the $person->id to the new Controller?

In my show.blade.php for Person I added

{{ HTML::linkRoute('email.adduseremail','Προσθήκη Email',array($person->id))}}

and I added to my EmailController

public function adduseremail($id)
{
    return View::make('email.createforuser',['id'=>$id]);
}

public function storeforuser($pid)
{
    $validator = Validator::make(Input::all(),Email::$rules);

    if ($validator->fails()) {
        $messages = $validator->messages();
        foreach ($messages->all('<li>:message</li>') as $message)
        return Redirect::back()->withInput()->WithErrors($messages);
    }
    $person = Person::FindorFail($pid);

    $email = new Email;
    $email->email = Input::get('email');
    $email->person()->associate($person);
    $email->save();

    return Redirect::route('person.index');
}

and my createforuser view is

<p>
{{Form::open(['route'=>'email.storeforuser'])}}
<div>
    {{Form::label('email', 'Email:')}}  
    {{Form::input('text', 'email')}}
    {{$errors->first('email')}}
</div>
</br>
<div>
{{Form::submit('Submit')}}
</div>
{{Form::close()}}
<p>

I keep getting Trying to get property of non-object (View: /var/www/laravel/app/views/email/show.blade.php )

Is there any example using Form and Models for inserting new objects to the database for 'belongsTo' Relationship? I couldn't find anything complete , just partial examples.

Answer 1

I generally use laravel sessions or laravel cache to tempererally save an id that i need to use later like: Session::set('personId',$person->id); Session::get('personId');

The same is for cache except cache will only last for the current request session is persistent for the session Hope that helps

I am no sure if I 'm supposed to answer my own question but finally I found a solution. I set two new routes

Route::post('email/adduseremail/{pid}', array('uses'=>'EmailController@adduseremail','as' => 'email.adduseremail'));
Route::post('email/storeforuser/{pid}', array('uses' =>'EmailController@storeforuser','as' => 'email.storeforuser'));

and created the corresponding methods in my Controller

public function adduseremail($id)
{
$pname = Person::Find($id)->name;
$psurname = Person::Find($id)->surname;

return View::make('email.createforuser',array('id'=>$id,'name'=>$pname, 'surname'=>$psurname));
}

and

public function storeforuser($pid)
{
$validator = Validator::make(Input::all(),Email::$rules);
if ($validator->fails())
    {
    $messages = $validator->messages();
    foreach ($messages->all('<li>:message</li>') as $message)
    return Redirect::back()->withInput()->WithErrors($messages);
    }
    $person = Person::FindorFail($pid);
    $email = new Email;
    $email->email = Input::get('email');
    $email->person()->associate($person);
    $email->save();

    return Redirect::route('person.show',array($person->id));

}

then on my view blade pages I can pass the parameters from View to Form and so on

person.show.blade.php


{{Form::Open(array('route' => array('email.adduseremail', $person->id),'method' => 'POST','style'=>'display:inline;'))}}
{{Form::submit('Add Email')}}
{{Form::close()}}

and

email.createforuser.blade.php

{{Form::open(array('route'=>array('email.storeforuser',$id),'method' => 'POST','style'=>'display:inline;'))}}
{{Form::label('email', 'Email:')}}  
    {{Form::input('text', 'email')}}
    {{Form::submit('Submit')}}

Hope it helps others also
