python - 如何将请求/用户传递给 Django 模型

Question

这是我的模型:

class Exam(BaseModel):
    ...
    STATE_CHOICES = (
        (PASS, PASS),
        (FAILED, FAILED),
        (GREAT, GREAT),
    state = models.CharField(max_length=15, choices=STATE_CHOICES, default=PASS)
    ...

        def save(self, *args, **kwargs):
            request = kwargs.get('request', None)
            print(f'user {request.user} saved the model')
            super().save(*args, **kwargs)

    ...

这是我的管理模型，我覆盖了 save_model 方法以将请求传递给我的模型:

@admin.register(Exam)
class ExamModelAdmin(admin.ModelAdmin):
    ...
    fields = ('state',)
    list_display = ('state',)
    form = ExamForm
    ...

    def save_model(self, request, obj, form, change):
        obj.save(request=request)

但是我得到一个错误:

save() got an unexpected keyword argument 'request'

Django = 3.2

Answer 1

这将需要覆盖/修改模型的 save() 方法，例如:

class Exam(models.Model):
    ...
    def save(self, *args, **kwargs):
        request = kwargs.pop('request', None)
        # print(f'user {request.user} saved the model')
        ...
        super().save(*args, **kwargs)
