python - 在 Django 中，我无法从数据库中的 edit.html 表单中检索 Upload cv、Status、gender 的值，但我可以检索其他字段值

Question

在此处输入图像描述这是我的 edit.html 代码，在从数据库中检索值期间，它仅显示诸如 value={{ i.full_name}} 之类的文本字段，但是当我编写 value={{ i.cv}} 时，值={{ i.status}}, value={{ i.gender}} 它没有显示需要编辑的值我有两个选择字段和一个文件字段，而且当我上传 pdf 文件时它正在获取存储在媒体文件夹中，我在表格中显示该文件，但是如果我上传的文件名在上传后命名为 java.pdf，在原始名称之后更改为一些随机名称，如 java_hjh45.pdf 为什么会发生这种情况我不知道

这是我的edit.html

这是我的意见.py

#delete
def delete(request, id):
    i = ApplyForm.objects.get(id = id)
    i.delete()
    return redirect('account:dboard')

#edit
def edit(request, id):
    i = ApplyForm.objects.get(id = id)
    context = {
        'i' : i
    }
    return render(request, 'account/edit.html', context)
    
#update
def update(request, id):
    i = ApplyForm.objects.get(id = id)
    i.full_name = request.POST['full_name']
    i.email = request.POST['email']
    i.noticeperiod = request.POST['noticeperiod']
    i.preferredlocation = request.POST['preferredlocation']
    i.expectedlocation = request.POST['expectedlocation']
    i.currentctc = request.POST['currentctc']
    i.expectedctc= request.POST['expectedctc']
    i.recruiter_name = request.POST['recruiter_name']
    i.status = request.POST['status']
    i.gender = request.POST['gender']
    i.cv = request.FILES['cv']
    i.save()
    return redirect('account:dboard')

这是我的models.py

class ApplyForm(models.Model):
    full_name = models.CharField(max_length=300)
    email = models.EmailField(max_length=300)
    noticeperiod = models.CharField(max_length = 300)
    preferredlocation = models.CharField(max_length=300)
    expectedlocation = models.CharField(max_length=300)
    currentctc = models.CharField(max_length=300)
    expectedctc = models.CharField(max_length=300)
    recruiter_name = models.CharField(max_length = 300, null=True)
    status = models.CharField(max_length = 300,  null=True, choices= CATEGORY_CHOICES )
    gender = models.CharField(max_length=10, choices=GENDER_CHOICES)
    cv = models.FileField(upload_to='') 

我在这里想要两个解决方案

1.当文本字段为工作正常我得到的值意味着我可以在我的表单中使用这个 value={{ i.full_name}} 显示全名的值，但不能在选择和文件字段中显示

2. 当我通过表单上传文件并提交文件时，文件存储在媒体文件夹文件系统中，但名称会在我上传后立即更改，例如，如果我的原始文件名是 simple2.pdf，它会更改为一些随机名称，例如 sample2_fkuTqar .pdf 我不知道这背后的原因是什么，为此附上了一张图片
