Question

这些是我的Django模型：

class Videos(models.Model):

    Title = models.CharField(max_length=100, unique=False, help_text='video title')
    Description = models.TextField(null=True, unique=False, blank=True)
    Tags = models.CharField(max_length=250, unique=False, blank=True)
    Category = models.CharField("Category", max_length=32, default='28', choices=CATEGORIES, null=False, blank=False)
    Language = models.CharField("Language", max_length=32, default='EN', choices=LANGUAGES, null=False, blank=False)
    file = models.FileField(upload_to='videos/', null=True, blank=False, validators=[FileExtensionValidator(allowed_extensions=['mp4'])] )
    Playlist = models.CharField(max_length=100, unique=False)

    title_gen = models.BooleanField(default=False)



class TitleVideo(models.Model):
    video = models.ForeignKey(Videos, related_name='video_id', null=False, blank=False, on_delete=models.CASCADE)
    converted = models.BooleanField(
        default=False, help_text='video has ben converted (True | False)')

    publicato = models.BooleanField(
        default=False, help_text='video has ben published (True | False)')

我需要获取所有具有TitleVideo.converted = false和Videos.title_gen = True的视频，我该怎么做？

Answer 1

也许尝试：

from django.db.models import Q

将导致

Video.objects.filter(Q(title_gen=True) & Q(video_id__converted=False))

Django过滤来自不同模型的对象
