$unique = $supporter->supporters->unique();
#endphp
#foreach($unique->values()->all() as $user)
...

...
#endforeach
#endforeach
Do not try to do unique on the collection, try to get your data already filtered from your database. You could group by any of your relationships attributes, just pass in a closure to handle the query for the eager-loaded content, something like:
$allTickets = Ticket::with(['user','replies'])->with([
'supporters' => function($query) {
$query->groupBy('id');
}
])->whereUserId(auth()->user()->id)->get();
Or you can query like this:
$allTickets = collect(Ticket::with(['user','replies','supporters'])->whereUserId(auth()->user()->id)->get());
$allUniqueTickets = $allTickets->unique();
$tickets = $allUniqueTickets->values()->all();
That's how you can easily get all the unique values from your controller. I hope this answers your question.
For more information, you can check https://laravel.com/docs/7.x/collections#method-unique

Function to get all the required data:
$auditResults = Audit::where('audit_id', $id)
->with('questionDetail')
->with('questionDetail.auditQuestion')
->get();
Which returns (streamlined):
Audit {#427 ▼
#relations: array:1 [▼
"questionDetail" => AuditQuestionDetail {#449 ▼
#relations: array:1 [▼
"auditQuestion" => AuditQuestion {#471 ▼
#original: array:5 [▶]
}
]
}
]
}
How can I loop within the view, to reach the auditQuestion relationship, for each Audit?
I have tried:
#foreach($auditResults->questionDetail->auditQuestion as $answer)
But I get:
Undefined property:
Illuminate\Database\Eloquent\Collection::$questionDetail
Many thanks.
** Issue with first relationship: **
Collection {#470 ▼
#items: array:18 [▼
0 => Audit {#427 ▼
#fillable: array:4 [▶]
#attributes: array:7 [▶]
#original: array:7 [▶]
#relations: array:1 [▼
"questionDetail" => AuditQuestionDetail {#449 ▼
#table: "audit_questions_details"
#fillable: array:3 [▶]
#attributes: array:7 [▶]
#original: array:7 [▼
"id" => 2
"audit_question_id" => 2

"updated_at" => "2017-03-26 13:40:18"
]
In Laravel 5.4, you can use higher order messages to do this cleanly:
#foreach($auditResults->map->questionDetail->map->auditQuestion as $answer)
Use nested loops:
#foreach ($auditResults as $result)
#foreach ($result->questionDetail as $detail)
#foreach ($detail->auditQuestion as $question)
{{ $question->id }}
#endforeach
#endforeach
#endforeach
In my Laravel project I have the following problem. (I have reduced the output a little for easier readability)
I fetch all the posts from a table named Newsposts. I store this as a collection called $all_posts, which looks like this:
Collection {#216 ▼
#items: array:7 [▼
0 => NewsPost {#227 ▶}
1 => NewsPost {#228 ▶}
2 => NewsPost {#229 ▼
#attributes: array:6 [▼
"id" => 6
"title" => "Sample title"
"body" => "<p>Some html</p>"
"user_id" => 15
]
#original: array:6 [▶]
#casts: []
.
.
#guarded: array:1 [▶]
}
3 => NewsPost {#230 ▶}
4 => NewsPost {#231 ▶}
]
}
I then fetch all entries from another table called user_read witch contains all the posts the current user have read. This table contains a reference to the user with a 'user_id'-column, and a reference to the newsposts with a 'post_id'-column. I also store this in a collection, which looks like this:
Collection {#219 ▼
#items: array:2 [▼
0 => UserRead {#210 ▼
#attributes: array:4 [▼
"user_id" => 15
"post_id" => 6
]
#original: array:4 [▶]
#casts: []
.
.
#guarded: array:1 [▶]
}
1 => UserRead {#217 ▶}
]
}
So what I want to do now is take the $all_posts-collection and remove all the posts from $read_posts-collection, and store it in a new collection. Lets call it $unread_posts. How can i achieve this?
get all readed post id first, then use filter function to filter unread posts
$readedPosts = $user_read->pluck('post_id');
$unread_posts = $all_posts->filter(function($value) use ($readedPosts) {
return !in_array($value->id, $readedPosts);
})
Entity {#848 ▼
#attributes: array:3 [▼
0 => array:4 [▶]
1 => array:4 [▶]
2 => array:4 [▶]
]
}
is_array($dump) // False
is_array($dump[0]) // True
Why the first result is false?
How can i handle this as an array?
