django: get() 返回了不止一个自由职业者——它返回了 3

Question

我正在尝试将一名自由职业者分配给特定的演出，但它显示 get() 返回了不止一个自由职业者——它返回了 3 个！。我已经尝试让登录的自由职业者尝试创建这样的 git freelancer = get_object_or_404(Freelancers, user=user) 并且在我保存表格之前我分配了这样的值 new_form.creator = freelancer .

views.py

@login_required
def create_gig(request):
    user = request.user
    freelancer = get_object_or_404(Freelancers, user=user)
    if request.method == "POST":
        form = CreateGig(request.POST, request.FILES)
        if form.is_valid():
            new_form = form.save(commit=False)
            new_form.user = request.user
            new_form.creator = freelancer
            new_form.slug = slugify(new_form.title)
            
            new_form.save()
            messages.success(request, f'Gig Created Successfully, Would be Live Soon')
            return redirect('freelance:listings')
    else:
        form = CreateGig()
    context = {
        'form': form
        }
    return render(request, 'freelance/create.html', context)

models.py

class Gigs(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='gig_user')
    creator = models.ForeignKey(Freelancers, on_delete=models.CASCADE, related_name='gig_creator')
    title = models.CharField(max_length=1000, null=True, blank=True, verbose_name="Enter what you will do", default=" I will ")

在我的代码中，它正在获取一个已登录的用户实例，然后通过将自由职业者分配给创建的表单来创建演出。

@login_required
    def create_gig(request):
        freelancer = Freelancers.objects.get(user = request.user )
        if request.method == "POST":
            form = CreateGig(request.POST, request.FILES)
            if form.is_valid():
                new_form = form.save(commit=False)
                new_form.creator = freelancer
                new_form.slug = slugify(new_form.title)
                
                new_form.save()
                messages.success(request, f'Gig Created Successfully, Would be Live Soon')
                return redirect('freelance:listings')
        else:
            form = CreateGig()
        context = {
            'form': form
            }
        return render(request, 'freelance/create.html', context)

你也不需要在你看来这一行：

new_form.user = request.user

试试这个，如果您还需要任何帮助，请告诉我
