在 Django 中，我无法检索选择字段的值、文件字段中具有此值的文件字段 ={{i.cv} 以及类似的选择字段

Question

这是我的 edit.html 代码，在从数据库中检索值期间，它只显示像 value={{ i.full_name}} 这样的文本字段，但是当我写 value={{ i.cv}} 时，value= {{ 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。

这是我的edit.html

这是我的观点.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，而文本字段工作正常我得到的值意味着我可以在我的表单中显示全名的值，这个值={{ i.full_name}} 但不是选择和文件字段我不知道哪里出错了。

Answer 1

为您的更新功能

替换：

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

与：

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

你需要对所有字段都这样做，并且更新应该可以工作
