Error 'undefined relationship'

[robman70]

Hi,
I found this wonderful package that (theoratically) resolves a big problem but I get an error:

Illuminate\Database\Eloquent\RelationNotFoundException: Call to undefined relationship [ordersPackages] on model [App\Models\Order]

Can someone help me?

Here are my involved models and their relationships:

Order

	/**
	 * @return \Illuminate\Database\Eloquent\Relations\HasMany
	 */
	public function ordersRows()
	{
		return $this->hasMany('App\Models\OrdersRow');
	}

	public function ordersPackages()
	{
		return $this->hasManyDeep(OrdersPackage::class, [OrdersRow::class, OrdersRowPackage::class]);
	}

The problem, obviously, is in ordersPackages()

OrdersRow

	/**
	 * @return \Illuminate\Database\Eloquent\Relations\HasMany
	 */
	public function ordersRowsPackages()
	{
		return $this->hasMany('App\Models\OrdersRowsPackage', 'order_row_id');
	}

OrdersRowsPackage

	/**
	 * @return \Illuminate\Database\Eloquent\Relations\BelongsTo
	 */
	public function ordersRow()
	{
		return $this->belongsTo('App\Models\OrdersRow', 'order_row_id');
	}
	
	/**
	 * @return \Illuminate\Database\Eloquent\Relations\BelongsTo
	 */
	public function ordersPackage()
	{
		return $this->belongsTo('App\Models\OrdersPackage', 'order_package_id');
	}

OrdersPackage

	/**
	 * @return \Illuminate\Database\Eloquent\Relations\HasMany
	 */
	public function ordersRowsPackages()
	{
		return $this->hasMany('App\Models\OrdersRowsPackage', 'order_package_id');
	}

Hi @robman70,
What code/query are you executing when you get this error?

[robman70]

Here is an excerpt:

			Order::select(
				<some_fields>
			)
				->with([
					'ordersRows' => function ($query) {
						$query
							->where('deleted', 0);
					},
					'ordersPackages' => function ($query) {
						$query
							->where('deleted', 0);
					},
				])

ordersRows works, ordersPackages not

[staudenmeir]

Can you share the whole stacktrace of the exception?

I'm using Laravel 9

[staudenmeir]

Can you share the whole Order model? What columns does the orders table have?

Does Order::find($id)->ordersPackageswork?

[robman70]

ops ... I noticed now that your library declaration is unused.

I declared it under the namespace, outside the class (with and without leading backslash).
If I declare it within the class, it doesn't find it (I have noticed now).
But the package seems ok, it's in my composer.json and I see the folder inside 'vendor'.

What's the error message?

But the package seems ok, it's in my composer.json and I see the folder inside 'vendor'.

Does the package show up in composer show?

use \Staudenmeir\EloquentHasManyDeep\HasRelationships;
With or without the leading backslash, same error.
And if I move this row after the namespace declaration, the resource is not used

[staudenmeir]

Undefined type Staudenmeir\EloquentHasManyDeep\HasRelationships

Please the full stacktrace of this error.

[robman70]

There is no stacktrace for this particular error: I see this error in VS Code, in design mode, not in runnig mode.

If I try to run a request to (for example) Order::find($id)->ordersPackages, I see this stacktrace:

There is no stacktrace for this particular error: I see this error in VS Code, in design mode, not in runnig mode.

That's actually a huge difference, the error in VS Code is meaningless here.

Error: Class "App\Models\OrdersRowPackage" not found

You are mixing OrdersRowPackage and OrdersRowsPackage (with an "s") in your code.

oh, no ...! What an ugly and stupid mistake!
I apologize and thank you very much, your help was really precious, thank you very much!
Now I have to fix something because it still doesn't work but the biggest problem I think was what you found

[robman70]

Now it works, thanks again!
