Django error ValueError: Field 'id' expected a number but got ''

I create django model for keep api_key as char like this.

class DeviceKey(models.Model):
    
    api_key=models.CharField(max_length=100,unique=True)
    limit_device=models.IntegerField()
    created=models.DateTimeField(auto_now_add=True)
    updated=models.DateTimeField(auto_now=True)

    
    def __str__(self):
        return self.api_key
    

    class Meta:
        ordering=('api_key',)
        verbose_name='DEVICE KEY'
        verbose_name_plural='DEVICE KEY'
        
class Device(models.Model):
    api_key=models.ForeignKey(DeviceKey,on_delete=models.CASCADE)
    name = models.CharField(max_length=100)
    status=models.BooleanField()
    switch=models.BooleanField(default=False)
    timer=models.BooleanField(default=False)
    category=models.ForeignKey(Category,on_delete=models.CASCADE)
    created=models.DateTimeField(auto_now_add=True)
    updated=models.DateTimeField(auto_now=True)

    def __str__(self):
        return self.name

    class Meta:
        ordering=('api_key',)

I create function device() in views.py for get data by using api_key like this.

def device(request):

    key = request.GET.getlist('key')
    data=Device.objects.filter(api_key__in=key).values_list('name','status')
    
    return JsonResponse(list(data), safe=False)
   

In admin page I create sample api_key as 2eaWe. when I run and send api_key to function device() it show error like this traceback.

    ValueError: Field 'id' expected a number but got '2eaWe'.

How to fix error ValueError: Field ‘id’ expected a number ?

>Solution :

data=Device.objects.filter(api_key__in=key).values_list('name','status')

that mean you will search in api_key model using id

if you want to search by api_key the query should be

data=Device.objects.filter(api_key__api_key__in=key).values_list('name','status')
