django覆盖模型save()方法

Question

我想request在save()方法中作为参数获取.

models.py

class Profile(models.Model):
    uuid = UUIDField(auto=True)
    user = models.ForeignKey(User)
    name = models.CharField(max_length=128)
    dob = models.DateField()

    class Meta:
        db_table = 'profile'

    def save(self,*args,**kwargs):
        if not self.pk:
            self.user_id = 2  #here i need request.user instead of 2
        super(Profile,self).save(*args,**kwargs)

forms.py

class ProfileForm(forms.ModelForm):

    class Meta:
        model = Profile
        exclude = ['uuid','user']

views.py

def add(request):
    profile_form = ProfileForm(request.POST)
    profile_form.save()

而不是2我想传递的价值request.user.我该怎么做.如果问题不正确,有人请更正问题.

Answer 1

不要在模型中这样做.在视图中执行.

profile_form = ProfileForm(request.POST)
if profile_form.is_valid():
    profile = profile_form.save(commit=False)
    profile.user = request.user
    profile.save()

Answer 2

一种方法是使用crequest,如下所示:

# model
from crequest.middleware import CrequestMiddleware

class Profile(models.Model):
    # Some fields
    def save(self, *args, **kwargs):
        crequest = CrequestMiddleware.get_request() #its the current request
        if crequest.user.pk is 1:
            # Do stuff
           pass
    super(Profile,self).save(*args,**kwargs)
