Python 在Django中，我无法检索选项字段、文件字段中具有此值={I.cv}的文件字段以及类似的选项字段的值

这是我的edit.html代码，在从数据库检索值的过程中，它只显示像value={{i.full{u name}}这样的文本字段，但是当我编写value={{i.cv}，value={{i.status}，value={{i.gender}时，它不显示需要编辑的值，我有两个选择字段和一个文件字段

这是我的edit.html

这是我的模特

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='') 

我想要一个解决方案

---

1.我无法通过执行value={{I.cv}，value={{I.Status}，value={{I.Gender}来检索Upload cv，Gender，Status的值。当文本字段工作正常时，我得到的值意味着我可以用这个值={I.full_name}显示全名的值在我的表单中，而不是选项和文件字段中，我不知道哪里出错。

用于更新功能

替换：

i.full_name = request.POST['full_name']

与：

您需要对所有字段执行此操作，并且更新应该有效

其他字段与文本字段一样有效只有三个字段无效上载简历、性别、状态两个选择字段和一个我正在上载PDF的领域检查我的html，如果我做了任何错误或没有，您已经发布了相同的帖子..Pl请尝试更具体地解决一个问题，只发布相关的代码部分，否则很难提供帮助。再次澄清：您需要了解HTML标记“radio”是如何使用的，另一方面，Django标记是如何使用的，以及3.如何使用Django文件字段and对象“文件”。

i.full_name = request.POST['full_name']

i.full_name = request.POST.get('full_name')
