Django-TypeError-save()得到了意外的关键字参数'force_insert'
问题描述:
我是Django的新手,我无法弄清楚这个错误。请帮助。它提供了TypeError-save()得到了意外的关键字参数 force_insert。我测试了下面的代码,他们能够保存新的用户注册,但现在将不再保存...
Im new in Django and I can't figure out this error. Help please. It gave TypeError - save() got an unexpected keyword argument 'force_insert'. I tested the code below and they were able to save the new user registration but now it won't save anymore...
这是views.py的一部分我认为出现了一些问题:
Here is part of the views.py that i think got some problem:
from django.shortcuts import render, redirect
from django.contrib.auth.forms import UserCreationForm
from django.contrib import messages
from django.contrib.auth.decorators import login_required
from . forms import UserRegisterForm, UserUpdateForm, ProfileUpdateForm
def register(request):
if request.method == 'POST':
form = UserRegisterForm(request.POST)
if form.is_valid():
username = form.cleaned_data.get('username')
form.save(force_insert=False)
messages.success(request, f'Thank you {username}! Your account has been created!')
return redirect('login')
else:
form = UserRegisterForm()
return render(request, 'users/register.html', {'form':form})
和模型。 py
from django.db import models
from django.contrib.auth.models import User
from PIL import Image
class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
image = models.ImageField(default='profile_pics/default.jpg', upload_to='profile_pics')
def __str__(self):
return (self.user)
def save(self):
super().save()
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)'
答
在Django中覆盖模型的save方法时,还应该传递 * args
和 ** kwargs
覆盖方法。这段代码可能工作正常:
When you are overriding model's save method in Django, you should also pass *args
and **kwargs
to overridden method. this code may work fine:
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)'
