我想知道如何根据在先前表单字段（公司）中选择的值填充选择字段（联系人和其他联系人）。例如我的表格：

class AddTicketForm(ModelForm):
    class Meta:
        model = Ticket
        fields = (
            'issue_type',
            'company',
            'contact',
            'additional_contacts',
            'priority',
            'subject',
            'description',
        )

从模型：

class Ticket(models.Model):

    issue_type = models.ForeignKey(SubIssueType)

    contact = models.ForeignKey(
        User,
        related_name='ticket_contact',
    )

    assigned_to = models.ForeignKey(
        User,
        related_name='ticket_assigned_to',
    )

    company = models.ForeignKey(
        Company,
    )

    additional_contacts = models.ManyToManyField(
        User,
        null=True,
        blank=True,
    )

    priority = models.CharField(
        'Priority',
        max_length=50,
        choices = ticket_priority_choices,
    )

    subject = models.CharField(
        'Subject',
        max_length=255,
    )

    description = models.TextField(
        'Description',
    )

    ...

class UserProfile(models.Model):

    user = models.ForeignKey(User, unique=True)

    company = models.ForeignKey(
        Company,
    )

    phone_number = models.CharField(
        'Phone Number',
        max_length=12,
    )

    relationship = models.CharField(
        'Relationship',
        max_length=30,
        choices=(
            ('customer', 'Customer'),
            ('support', 'Support'),
        )
    )
    ...

因此，根据为公司选择的内容，我只想填充作为该公司成员的用户的联系人和附加联系人。这可能与 Django 纯粹有关，还是我需要考虑 JavaScript 来提供帮助？将不胜感激任何指导。
