Laravel: Property [Name] Does Not Exist on This Collection Instance

Property [title] does not exist on this collection instance

When you're using get() you get a collection. In this case you need to iterate over it to get properties:

@foreach ($collection as $object)
    {{ $object->title }}
@endforeach

Or you could just get one of objects by it's index:

{{ $collection[0]->title }}

Or get first object from collection:

{{ $collection->first() }}

When you're using find() or first() you get an object, so you can get properties with simple:

{{ $object->title }}

Property [image] does not exist on this collection instance. / Laravel - with() Method

the problem is that the variable $employee (which contains model Post btw)
has relation 1:N to People I assume

meaning you have to loop the people collection returned by the relation

e.g.

@foreach($employees as $employee)
   @foreach($employee->people as $person)
      {{ $person->image }}
   @endforeach
@endforeach

Property [id] does not exist on this collection instance?

Try this solution:

You have a error in this query

$products = Product::where('user_id', $user_id)->get();

because $user_id is an object of the User, not a single value.

Your Code:

public function show($id)
{
    //
    $user_id = User::find($id);
    if (is_null($user_id)) {
        return response()->json([
            'message' => 'User Not Found',
            'status' => 404
        ], 404);
    }
    $products = Product::where('user_id', $user_id)->get();
    return response()->json([
        'data' => new UserProductResource($products),
        'status' => 200
    ], 200);
}

New Code:

public function show($id)
{
    //
    $user = User::find($id);
    if (is_null($user)) {
        return response()->json([
            'message' => 'User Not Found',
            'status' => 404
        ], 404);
    }
    $products = Product::where('user_id', $user->id)->get();
    return response()->json([
        'data' => new UserProductResource($products),
        'status' => 200
    ], 200);
}

Laravel: Property [name] does not exist on this collection instance while trying to populate field in a Edit view

Thank you everyone for your time

All of your answers where very helpful, but it turns out i just made a typo.

In the edit route
Route::get('/product/{article}/edit', [ProductController::class, 'edit']);
I wrote {article} instead of {product} (Both the model and controller where named Product) as stated by @ByWaleed. After making that correction everything works correctly.

As a recomendation for future users, if posible use Route::resource() instead of writing each route individually it makes it less likely to make a mistake as te one i did.

Again thank you everyone.

Property [name] does not exist on this collection instance

Because the areas is a collection so you should loop over it like this :

@foreach($users as $u)
    <tr role="row" class="odd">
        <td class="sorting_1">{{$u->name}}</td>
        <td></td>
        <td>
        @foreach($u->areas as $area)
            {{$area->name}}, 
        @endforeach
        </td>
        <td>{{route('show_user', ['id' => $u->id])}}</td>
    </tr></tbody>
@endforeach

And if you want to separate them whith comma for example you can do it like that without looping :

    @foreach($users as $u)
    <tr role="row" class="odd">
        <td class="sorting_1">{{$u->name}}</td>
        <td></td>
        <td>
            {{ $u->areas->pluck('name')->implode(', ') }}
        </td>
        <td>{{route('show_user', ['id' => $u->id])}}</td>
    </tr></tbody>
@endforeach

Property [users] does not exist on this collection instance

You had missed the exact foreign key between your users table and usertypes table.

First, you defined the that the foreign key of your user table is 'ut_id' base of what you had in your belongsTo relationship. On this one

/**
 * Get the user type that user has.
 */
public function users(){
    return $this->belongsTo('App\Models\UserType', 'ut_id', 'id');
}

Second is that, in your user type model, you used a foreign key to user table named 'user_type_id', which is at first you named it as 'ut_id' in your users table. On this one

/**
 * The primary key associated with the table.
 *
 * @var string
 */
protected $primaryKey = 'ut_id';

/**
 * Get the user associated with the user type.
 */
public function users(){
    return $this->hasOne('App\Models\Users', 'user_type_id', $primaryKey);
}

You have to match this foreign keys you used to solve your problem.

Now, to fetch your all user with their types, your query should look like this.

$users = Users::with('users')->get();

assuming that your user table has this relationship

public function users(){
    return $this->belongsTo('App\Models\UserType', 'ut_id', 'id');
}

and your user types model has this relationshio

public function users(){
    return $this->hasOne('App\Models\Users', 'ut_id', $this->primaryKey);
}

in laravel Property [password] does not exist on this collection instance

using get() returns a collection and you need to loop through it to get a property. use first() that will return an object to which the property exist.

$admin = User::with('usermetas')->where('username',$username)->
    orWhere('email',$username)->where('admin','0')->first();

Property [group] does not exist on this collection instance

$product->groupproducts is a collection(array) of products.
You can do:

dd($product->groupproducts->first()->group->name);

This will get first element from collection which is instance of Group class.
