在 crontab 上尝试了数据库查询集，但它不起作用

Question

Crontab works fine on simple task. eg

def test():
    test.objects.create.(name='Dino')

#It also works on this
def test_task()
    if Users_Machine.objects.filter().exists():
        test.objects.create(name='Dino')

but when i tried to query my db with foreignkey it does nothing.

Have tried this two methods:

#request method
def test_task(request):
    if Users_Machine.objects.filter(user=request.user).exists():
        test.objects.create(name='Dino', user=request.user)

#direct methods
def test_task()
    if Users_Machine.objects.filter().exists():
        name=Users_Machine.objects.get()
        test.objects.create(name='Dino', user=name.username)

The Users_Machine.object returns True

Here is my models

#users_machine model
class Users_Machine(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    Name = models.CharField(max_length=20)

#test model
class test(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    name  = models.CharField(max_length=100)

Please how can i make this work?

Answer 1

It would be better if I get to look at User model but for now I am going to assume in the request, you are passing Name field which is present in the UserMachine model and you can create new object in test model as follows:

def test_task(request):
    Current_user = User_Machine.objects.get(Name = request.name)  
    if Current_user:
        test.objects.create(name='Dino', user=Current_user)

Can you please add User model as well, that will allow me fine tune the answer (or correct it if this one is wrong)?
