How to retrieve all data blocks from database at a certain entry in Django?

Question

I am very sorry for this newbie question... I have data stored in the database (mysql) as tuples. These data look like (datetime, frequency, current) ... etc.

How to retrieve all data from database at a certain time? for example, I want to get all the saved data at "2015-9-9 8:23:10"

Answer 1

can you show your model.

You can add created and updated fields to your model and query them to retrieve your data

class Test(models.Model):
    created = models.DateTimeField(
        default=django.utils.timezone.now, blank=True)
    updated = models.DateTimeField(
        default=django.utils.timezone.now, blank=True)

you can query the Test model then using the time you want

Test.objects.all(created=datetime.now())

Answer 2

如果datetime field是创建数据的日期，您可以执行以下操作：

Test.objects.all(datetime__gte=timezone.now)
