如何将当前活动用户作为外键添加到django 3的任务模型中？

from django.db import models
from django.contrib.auth.models import User

class Task(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    # 其他任务字段...

from django.shortcuts import render, redirect
from django.contrib.auth.decorators import login_required
from .models import Task

@login_required
def create_task(request):
    if request.method == 'POST':
        task = Task()
        task.user = request.user  # 当前活动用户
        # 设置其他任务字段...
        task.save()
        return redirect('task-list')
    else:
        return render(request, 'create_task.html')
