Laravel 5.1 - compare Carbon dates - laravel

Question

Here I need to check does auction for article in my app is live so I write in Article model:
public function scopeCloseauction($query){
$query->where(Carbon::parse('to')->subDays('auction_end'),'>',Carbon::now());
}
and view I have:
#if ($article->Closeauction())
<td>
auction is live
</td>
#else
<td>
auction is closed
</td>
#endif
but I have a problem becouse I got error:
UPDATE:
I also try:
in model to add function:
public function isLive($to,$auction_end) {
$first = Carbon::create($to).subDays($auction_end);
$second = Carbon::now();
return ($first->lte($second));
}
and in view:
#if ($article->isLive($article->to,$article->auction_end))
<td>
live
</td>
#else
<td>
closed
</td>
#endif
but now give me this error:
ErrorException in Carbon.php line 425: Unexpected data found.
Unexpected data found. Unexpected data found. Trailing data (View:
C:\wamp\www\project\resources\views\articles\index.blade.php)

Answer 1

You can do something add such function into your Article model:
public function isLive()
{
$first = Carbon::parse($this->to)->subDays($this->auction_end);
$second = Carbon::now();
return $first->lte($second);
}
and now in your view you can use:
#if ($article->isLive())
<td>
live
</td>
#else
<td>
closed
</td>
#endif

I think your problem is here : Carbon::parse('to'). What do you want to do here ? the Carbon::parse method try to convert a string date into a Carbon date. See the doc. I dont think that Carbon can parse the string 'to'. If you want to check the diff between dates, you should have a look to the appropriated methods like diffInDays.
