Django 中的类型错误：save() 得到了意外的关键字参数“force_insert”

Question

这是关于课程中的一个博客项目，它似乎适用于许多其他学生，但不适用于我。所以我想看看我的代码出了什么问题。错误信息是：TypeError at /register/save() got an unexpected keyword argument 'force_insert'与问题文件相关的内容如下：users/ views.py：（在register函数的第四个原始中是失败的save()方法）from django.shortcuts import render, redirectfrom django.contrib import messagesfrom django.contrib.auth.decorators import login_requiredfrom .forms import UserRegisterForm, UserUpdateForm, ProfileUpdateFormdef register(request):    if request.method == 'POST':        form = UserRegisterForm(request.POST)        if form.is_valid():            form.save()            username = form.cleaned_data.get('username')            messages.success(request, f"Your account has been created! You are now able to log in")            return redirect('login')    else:        form = UserRegisterForm()    return render(request, 'blog/register.html', {'form': form})@login_requireddef profile(request):    if request.method == 'POST':        u_form = UserUpdateForm(request.POST, instance=request.user)        p_form = ProfileUpdateForm(request.POST, request.FILES, instance=request.user.profile)        if u_form.is_valid() and p_form.is_valid():            u_form.save()            p_form.save()            messages.success(request, f"Your account has been updated!")            return redirect('profile')    else:        u_form = UserUpdateForm(instance=request.user)        p_form = ProfileUpdateForm(instance=request.user.profile)    context = {        'u_form': u_form,        'p_form': p_form    }    return render(request, 'blog/profile.html', context)用户/模型.py：from django.db import modelsfrom django.contrib.auth.models import Userfrom PIL import Imageclass Profile(models.Model):    user = models.OneToOneField(User, on_delete=models.CASCADE)    image = models.ImageField(default='default.jpg', upload_to='profile_pics')    def __str__(self):        return f"{self.user.username} Profile"

当重写saveDjango 中的方法时，也应该保留签名。

更改为def save(self, *args, **kwargs)：

    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:

            output_size = (300, 300)

            img.thumbnail(output_size)

            img.save(self.image.path)
