Question

我正在尝试制作一个编辑用户个人资料表单，我的问题是，如果我不从表单中排除用户，它会要求它，但如果我排除它我会得到：

错误：

IntegrityError at /apps/edit-profile
null value in column "user_id" violates not-null constraint
DETAIL:  Failing row contains (21, 85.75, Alexe, Bogdan, null, Romania, null, null, null, null).

models.py

    class UserProfile(models.Model):
        user = models.OneToOneField(settings.AUTH_USER_MODEL)
        balance = models.DecimalField(max_digits=6, decimal_places=2, default=0.00, blank=True, null=True)
        first_name = models.CharField(max_length=200, blank=True, null=True, default=None)
        last_name = models.CharField(max_length=200, blank=True, null=True, default=None)

forms.py

class UserProfileForm(ModelForm):

    class Meta:
        model = UserProfile
        fields = '__all__'
        exclude = ('user', )

    def __init__(self, *args, **kwargs):
        super(UserProfileForm, self).__init__(*args, **kwargs)
        for field in self.fields:
            self.fields[field].widget.attrs.update({'class': 'form-control'})

views.py

@login_required
def user_profile(request):
    data = dict()
    if request.method == 'POST':
        profile = get_object_or_404(UserProfile, user=request.user)
        form = UserProfileForm(request.POST, profile)
        if form.is_valid():
            profile = form.save(commit=False)
            profile.balance = Income.objects.filter(assigned_to__username=request.user).aggregate(sum=Sum('value'))['sum']
            profile.save()
            return redirect('/apps/home')
    else:
        form = UserProfileForm()
    data['form'] = form
    return render(request, 'core/profile.html', data)

profile.html

<form class="js-validation-bootstrap" action="" method="post">
    {% csrf_token %}
    {{ form.errors }}
    <div class="form-group row">
        <label class="col-lg-4 col-form-label" for="val-username">First Name </label>
        <div class="col-lg-8">
            <input type="Text" class="form-control" id="val-username" name="first_name" placeholder="">
        </div>
    </div>
    <div class="form-group row">
        <label class="col-lg-4 col-form-label" for="val-username">Last Name </label>
        <div class="col-lg-8">
            <input type="Text" class="form-control" id="val-username" name="last_name" placeholder="">
        </div>
    </div>
    <div class="col-lg-8 ml-auto">
        <button type="Submit" class="btn btn-alt-primary">Submit</button>
    </div>
</div>
</form>

我不明白为什么它会给我这个错误。

您可以在视图中添加当前用户，即使此字段已排除在外：

profile = form.save(commit=False)
profile.user = request.user
profile.save()

Django无法编辑用户个人资料
