Question

你好，当用户(schooluser(注册时，我试图创建一个学校配置文件，该配置文件已创建，但在/register/user处出现错误RelatedObjectDoesNotExist时，没有学校配置文件。奇怪的是，在管理员中，当您试图编辑创建的学校配置文件的任何字段时，模型字段都是空的。帮助

型号.py

class SchoolProfile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE,related_name='schoolprofile')

def __str__(self):
return f'{self.user.username} Profile'
def save(self, *args, **kwargs):
super().save(*args, **kwargs)

forms.py

from django import forms

s_profile_form = SchoolProfileForm(request.POST)
if form.is_valid() and s_profile_form.is_valid():
form.save()
request.user.refresh_from_db()  
s_profile_form = SchoolProfileForm(request.POST, instance=request.user.schoolprofile)
s_profile_form.full_clean()

Answer 1

您使用request.user.schoolprofile，但您的用户(现在(本身没有相关的SchoolProfile对象，因此出现错误。此外，创建用户不会(自动(登录该用户。您可以更改封装在s_profile_form:中的实例中的.user字段

def register(request):
if request.method == 'POST':
form = SchoolRegisterForm(request.POST)
s_profile_form = SchoolProfileForm(request.POST)
if form.is_valid() and s_profile_form.is_valid():
user =form.save()
s_profile_form.instance.user = user
s_profile_form.save()
messages.success(request, f'Your account has been created! You are now able to log in!')
return redirect('dashboard')
else:
form = SchoolRegisterForm()
s_profile_form = SchoolProfileForm()
return render(request, 'accounts/register.html', {'form': form,'s_profile_form':s_profile_form})

注意：通常使用settings.AUTH_USER_MODEL[Django-doc]来引用用户模型比直接使用User模型[Django-dc]更好。有关更多信息，请参阅文档中引用User模型的部分。
