Question

我正在尝试从内置的User模型内置的django中保存当前登录用户的用户名。

model.py

class Notes(models.Model):
    username = models.ForeignKey(User, on_delete=models.CASCADE)
    note = models.CharField(max_length = 100000000)

    def __str__(self):
        return self.note

views.py

@login_required
def saveNote(request):
    if request.method == 'POST':
        note = request.POST['note']
        print(request.user.username)
        note = Notes(username=request.user.username ,note = request.POST["note"])
        note.save()
    return redirect('/')

但这显示了一个错误。我想将当前用户与注释一起保存在Notes表中。我应该怎么做？

您的代码中几乎没有错误。

首先

username = models.ForeignKey(User, on_delete=models.CASCADE)

应该是

user = models.ForeignKey(User, on_delete=models.CASCADE)

和

note = models.CharField(max_length = 100000000) charfield can hold 255 char

所以你需要

note = models.TextField()



  @login_required
    def saveNote(request):
        if request.method == 'POST':
            note = request.POST['note']
            print(request.user.username)
            note = Notes(username=request.user #user=request.user if you change your model field name
 ,note = note)
                note.save()
            return redirect('/')

使用Django中内置的用户模型
