关于表格的问题，我如何在表单字段中获得即时用户pyhton django

Question

我已经构建了一些用户到用户消息功能。我有发件人，接收器和文本请参见下面。现在，用户必须选择他的电子邮件，然后选择该邮件应向的电子邮件。 但是我想要的是，用户不需要自己选择自己，我需要一个立即查询的表单函数。但是我不知道如何以形式实施。并且用户未显示在接收器列表中。我的英语不好，希望你能理解我。

views.py

def mailEMployee(request):
    mail = Mailsysthem.objects.filter(ontvanger=request.user)
    receiver = Mailsysthem.objects.filter(ontvanger=request.user)
    sender = Mailsysthem.objects.filter(zender=request.user)
    user = CustomUser.objects.filter(email=request.user)
    form = Mailsythemform()
    if request.method == 'POST':
       form = Mailsythemform(request.POST, request.FILES)
    if form.is_valid():
       form.save()
       return redirect('mail')
   context={
   'form':form,
   'receiver':receiver,
   'sender':sender.all,
   'mail':mail,
   'user':user
    }
   return render(request,'emp/mail.html', context)

forms.py

class Mailsythemform(forms.ModelForm):

class Meta:
    model= Mailsysthem
    fields= ['zender','ontvanger','subject','text']

models.py

class Mailsysthem(models.Model):
zender = models.ForeignKey(to=CustomUser, null=True, on_delete=models.SET_NULL,related_name='Zender')
ontvanger = models.ForeignKey(to=CustomUser, null=True, on_delete=models.SET_NULL,related_name='Ontvanger')
subject = models.CharField(null=True, max_length=200)
text = models.TextField(max_length=300, null=True, blank=True, verbose_name='Bericht')
date = models.DateTimeField(auto_now_add=True, blank=True)
solftdelete = models.BooleanField(default=False)
mail_opened = models.BooleanField(default=False)

url.py

   path('mailemployee/', views.mailEMployee, name='mail'),

您需要为modelform提供初始值=“ nofollow noreferrer”> docs ）如下：

form = JournalForm(initial={'sender': user.id})
