在单个查询中搜索两个Django表一次

对于Django连接，我真的很困惑。我想用一个查询在两个表中搜索关键字。有人能帮我吗

应用程序模型结构如下所示

class Events(models.Model):
    event_type = models.CharField(_("Event Type"), max_length=5, choices=event_type_choices)
    webinar_title = models.CharField(_("Webinar Title"), max_length=50, blank=True, null=True)
    event_name = models.CharField(_("Event Name"), max_length=50, blank=True, null=True)
    banner_title = models.CharField(_("Banner Title"), max_length=50, blank=True, null=True)
    added_by = models.ForeignKey(User, null=True, blank=True, on_delete=models.SET_NULL)
    status = models.BooleanField(_("Event Status"), default=True)


    class Meta:
        verbose_name = _('Event')
        db_table = 'events'
        app_label = 'events'


class WebinarSpeakers(models.Model):
    event = models.ForeignKey(Events, on_delete=models.CASCADE, null=True)
    speaker = models.CharField(_("Speaker Name"), max_length=100, null=True, blank=True)
    job_title = models.CharField(_("Job Title"), max_length=255)
    place_of_work = models.CharField(_("Place of Work"), max_length=100)
    credentials = models.TextField(_("Credentials"), null=True, blank=True)
    image = models.ImageField(_("Speaker Image"), upload_to=speaker_file_name, null=True, blank=True)

    class Meta:
        verbose_name = _('Event Webinar Speakers')
        db_table = 'webinar_speakers'
        app_label = 'events'

---

现在我想在

webinar\u title

，

evetn\u name

，

banner\u title

，

speaker

，“job\u title”中搜索一个关键字，只需一个查询。如何在Django联接中执行此操作。我阅读了与select_相关的文档。这让我很困惑。

请解释一下你的答案，

WebinarSpeakers.objects.filter(event__webinar_title="something", event__event_name="something", event__banner_title="somethng", speaker="something",job_title="something")
