Laravel Relationship Issues : Laravel 5.4 - laravel

Question

I have 2 tables in my application... Users Conventioners
I have users id in the conventioners table and i want to access their genders from the Users table....
I have like 10 user ids in the conventioners table and 20 users in the users table...
Please how do I access all their genders in the users table...
$conventioners->users()->gender
Conventioners is an instance of the Conventioner Model which contains a relationship **belongsToMany
Thanks alot guys
Here is my Conventioner Model
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Conventioner extends Model
{
/**
* #var string
*/
protected $table = 'conventioners';
/**
* #var array
*/
protected $fillable = [
'user_id','year','church_id','convention_id'
];
/**
* #return \Illuminate\Database\Eloquent\Relations\BelongsTo
*/
public function user()
{
return $this->belongsTo('App\User');
}
/**
* #return \Illuminate\Database\Eloquent\Relations\HasMany
*/
public function users()
{
return $this->hasMany('App\User');
}
/**
* #return \Illuminate\Database\Eloquent\Relations\BelongsTo
*/
public function convention()
{
return $this->belongsTo('App\Convention');
}
}
Here is my ConventionController method called Convention...
It retrieves the details for the current convention
public function convention($slug)
{
if(!$this->admin()) return redirect()->back();
$convention = Convention::where('slug', $slug)->first();
$participants = Conventioner::where('convention_id', $convention->id)->get();
$conventioner = [];
foreach($participants as $participant)
{
$thisUser = [];
$thisUser['data'] = User::withTrashed()->where('id', $participant->user_id)->first();
$thisUser['convention'] = $participant;
array_push($conventioner, $thisUser);
}
var_dump($participants->users()->pluck('gender')->all());
return view('dashboard/conventions/convention', [
'convention' => $convention,
'user' => Auth::user(),
'conventioners' => $convention->conventioners(),
'participants' => $conventioner
]);
}

Answer 1

The problem is that users is a collection not an individual that you can call gender on. If you want a list of all the genders you can use the following:
Conventioner::where('convention_id', $convention->id)->with('users')->get()
$conventioners->pluck('users')->pluck('gender')->all();
This will return an array of the genders. You can read more about pluck here.
The pluck method retrieves all of the values for a given key
