relation "itouch_photo" does not exist [duplicate]

Question

i have an app hosted in heroku while i did not set debug = false, when i visit the website it's throws me an error like this:

relation "itouch_photo" does not exist
LINE 1: ...ch_photo"."price", "itouch_photo"."location" FROM "itouch_ph...

and also it highlight my template:

{% for photo in photos reversed %}

I did not use command prompt i developed an app through heroku dashboard.

how can i slove that:

the models:

class Photo(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    category = models.CharField(max_length=30,null=True, blank=False)
    image = CloudinaryField('image')
    description = models.TextField(null=True)
    date_added = models.DateTimeField(auto_now_add=True)
    phone = models.CharField(max_length=12, null=False, blank=False)
    price = models.CharField(max_length=30,blank=False)
    location = models.CharField(max_length=20, blank=False)

    def __str__(self):
        return str(self.category)

the views:

def dashboard(request):
    photos = Photo.objects.all()
    context = {'photos': photos}
    return render(request, 'dashboard.html', {'photos': photos} )    


def home(request):
    photos = Photo.objects.all()
    context = {'photos': photos}
    return render(request, 'home.html', {'photos': photos} )  

i think the problem is coming from this model up here
