Problem with laravel eloquent relationship - can't access relationship

Question

I am facing a problem with an Eloquent relationship. I am new and trying to learn.

I have 3 models:

1. village model - contain village names
2. Patient model - containing patient info
3. Serial model - containing patient serials

Relationships

• village model has many patients and patient belongs to the village model

• Patient model has many Serial models and the serial model belongs to the patient model

The serial model has date fields. I am making queries to get Serials whose dates match today and try to get the related model data.

Model codes

village has many Patient

public function patient()
{
    return $this->hasMany(Patient::class);
}

Patient model belongs to village

public function village()
{
    return $this->belongsTo(Village::class);
}

Patient has many serials

public function serials()
{
    return $this->hasMany(Serial::class);
}

Serial belongs to patient

public function patient()
{
    return $this->belongsTo(Patient::class);
}

I am getting Patient using Serial::where('date', '2022-05-11')->with(['patient'])->get();.

But I want to get the nested model like Serial::where('date', '2022-05-11')->with(['patient.village'])->get();

I am getting village undefined! How can I get the village through Serial, please?

Answer 1

I find the error. I have problem with foreignId constrained I wrote relationship for patient like -

$table->integer('village')->nullable()

But it should be -

$table->foreignId('village_id')->constrained()->nullable()
