forms.py from django import forms from models import UserProfile django的forms.py从模型导入表单
class UserProfileForm(forms.ModelForm):
class Meta:
model = UserProfile
fields = ('imie', 'godzina')
views.py views.py
from django.shortcuts import render
from django.http import HttpResponseRedirect
from django.core.context_processors import csrf
from forms import UserProfileForm
from django.contrib.auth.decorators import login_required
from django.conf import settings
@login_required
def user_profile(request):
if request.method == 'POST':
form = UserProfileForm(request.POST, instance=request.user.profile)
if form.is_valid():
form.save()
return HttpResponseRedirect('/accounts/loggedin')
else:
user = request.user
profile = user.profile
form = UserProfileForm(instance=profile)
args = {}
args.update(csrf(request))
args['form'] = form
return render(request, 'user_profile.html', args)
models.py: models.py:
from django.db import models
from django.contrib.auth.models import User
from godzina.models import Godzina
class UserProfile(models.Model):
user = models.OneToOneField(User)
imie = models.CharField(max_length=150)
godzina = models.ForeignKey('godzina.Godzina')
User.profile = property(lambda u:UserProfile.objects.get_or_create(user=u)[0])
您可以将null=True
添加到您的godzina
属性:
godzina = models.ForeignKey('godzina.Godzina', null=True)
