I created a profile page that uses DetailView, but the profile page just doesn't work on newly created users and is giving me this error message:
Internal Server Error: /user/Ryan/

ValueError: invalid literal for int() with base 10: 'Ryan'
The above exception was the direct cause of the following exception:

I am not sure if it is something related to the User creation/registration, so I also included the registration function
def register(request):
if request.method == 'POST':
f = UserRegisterForm(request.POST)
if f.is_valid():
p = f.save()
p.refresh_from_db()
p.profile.rank = f.cleaned_data.get('rank')
p.save()
username = f.cleaned_data.get('username')
messages.success(request, f'Account created for {username}')
return redirect('login')
else:
f = UserRegisterForm()
return render(request, 'users/register.html', {'form':f})
the signals
from django.contrib.auth.models import User
from django.db.models.signals import post_save
from django.dispatch import receiver
from .models import Profile
@receiver(post_save, sender=User)
def create_profile(sender, instance, created, **kwargs):
if created:
Profile.objects.create(user=instance)
@receiver(post_save, sender=User)
def save_profile(sender, instance, **kwargs):
instance.profile.save()
and the Profile model
class Profile(models.Model):
RANKS = [(f'{i}K', f'{i}K') for i in range(1,19)]
for i in range(1, 10):
RANKS.append((f'{i}D', f'{i}D'))
user = models.OneToOneField(User, on_delete=models.CASCADE)
image = models.ImageField(default='default.jpg', upload_to='profile_pics')
bio = models.CharField(max_length=225, blank=True, default='')
rank = models.CharField(max_length=3, default='18K', choices=RANKS)
teacher_status = models.BooleanField(default=False)
def __str__(self) -> str:
return f"{self.user.username}'s Profile"
def save(self, *args, **kwargs):
super(Profile, self).save(*args, **kwargs)
img = Image.open(self.image.path)
if img.height > 300 or img.width > 300:
img.thumbnail((300,300))
img.save(self.image.path)
I am new to django, I know I've probably provided a lot of useless information, thank you for your help:)
CodePudding user response：
You are using the username to get the Request
context['requests'] = Request.objects.filter(teacher=user.username, completed=False).order_by('-request_time')
I'm guessing that teacher is a Profile in your model, in any case, you are filtering by the username and teacher is a ForeginKey that is specting an id to filter. So, what you need to do is remove the username and filter only teacher=user. Please note that if teacher is not a ForeignKey to user you may need to use teacher__user=user as a filter.
CodePudding user response：
In Teacher == user.username you are trying to compare an int and a str.
I'm guessing that you have both models related with a Foreign key in user to a teacher. Try use the id on that relation to match with teacher.
Edit: You may wonder why your "teacher" is int when you (probably) declared a str name for the model, and the answer is that django provides by default autoincremental integer ids to all models and uses that id to create Foreign keys. You could also match the user.id with the teacher Foreign key to the user model, if that's how you structured you relationship.
