Create one to many table relationship with text input Laravel - php

Question

I have two tables with a one to many relationship - gratitude_journal_entries and self_gratitudes. Multiple self gratitudes (which are submitted as text entries by the user) can apply to 1 gratitude_journal_entry. The data is passed to these two tables via a form.
I am trying to store the self gratitude text entries in an array and then pass these to the self_gratitude table along with the foreign key from the gratitude_journal_entries table.
The problem I'm having is I'm not sure how to take the input from the array and store this in the self_gratitude column.
Here are the columns for the gratitude_journal_entries table
Here are the columns for the self_gratitudes table
Here are the models and the store method in my controller
class SelfGratitudes extends Model
{
protected $table = 'self_gratitudes';
public $primarykey = 'id';
public function gratitudeJournalEntries() {
return $this->belongsTo(GratitudeJournalEntry::class);
}
}
class GratitudeJournalEntry extends Model
{
protected $table = 'gratitude_journal_entries';
public $primarykey = 'id';
public $timestamps = true;
public function user() {
return $this->belongsTo('App\User');
}
public function selfGratitudes()
{
return $this->hasMany(SelfGratitudes::class);
}
public function store(Request $request)
{
$this->validate($request, [
]);
$gj_entry = new GratitudeJournalEntry;
$gj_entry->user_id = auth()->user()->id;
$gj_entry['entry_date'] = date('Y-m-d H:i');
$self_gratitudes = $request->has('self_gratitudes') ? $request->get('self_gratitudes') : [];
$tj_entry->save();
$gj_entry->selfGratitudes()->sync($self_gratitudes);
return redirect('/dashboard')->with('success', 'You submitted a new journal entry');
}

If you want to keep array in database you can use casting on your columns:
laravel document
class SelfGratitudes extends Model
{
protected $casts = [
'self_graitude' => 'array',
];
protected $table = 'self_gratitudes';
public $primarykey = 'id';
public function gratitudeJournalEntries() {
return $this->belongsTo(GratitudeJournalEntry::class);
}
}
