如何更新Laravel中的“一对多”关系？ （在文档中找不到）

Question

<?php
class User extends Eloquent {

    public function tickets()
    {
        return $this->hasMany('Tickets')

    }
}

class Tickets extends Eloquent {

    public function User()
    {
        return $this->belongTo('User')

    }
}


//and how to update a Ticket that belongs To User?


// and this dosen't work...Who can tell me the reason ,thanks !
$ticket = User::find(1)->tickets()->where('type','sometype')->get();
$ticket.update(array('status'   =>    0));

Answer 1

The update() query is documented quite plainly in the official docs:

User::find(1)->tickets()->where('type','sometype')->update(array('status' => 0));

I suspect the issue you're having is that the get()` query is returning multiple records. In order for your query to work, you'll need to treat the returned value as a collection if records, then iterate and operate on each record individually.

$tickets = User::find(1)->tickets()->where('type','sometype')->get();
foreach ($tickets as $ticket) {
    $ticket->update(array('status' => 0));
}

Note that the correct syntax for invoking an Eloquent method requires a preceding arrow -> – not a dot (.).

$record.update(array('foo' => 'bar'));   # Incorrect
$record->update(array('foo' => 'bar')); # CORRECT!

UPDATE:

Model names should always be singular, not plural. Therefore, the Ticket model should be defined as follows:

class Ticket extends Eloquent { // `Ticket`, not `Tickets`
    public function User()
    {
        return $this->belongTo('User')

    }
}
