Question

我正在使用django 2.0和python 3.6，我已经尝试了几乎所有方法来从request.FILES获取值，但是似乎没有任何效果，我认为我缺少了一些非常简单的东西，但是我找不到它

models.py

class Imagen(models.Model):
imagen = models.FileField(max_length=200, blank=True, upload_to='%Y/%m/%d/')

views.py

def prop_add(request):
  if request.method == 'POST':
    propiedad_instance = Propiedad(tipo = request.POST.get('tipo'), tamano=request.POST.get('tamano'), habitaciones = request.POST.get('habitaciones'), banos = request.POST.get('banos'), descripcion= request.POST.get('descripcion'), direccion= request.POST.GET('descripcion'), precio= request.POST.get('precio'), ubicacion= Ubicacion.objects.get(barrio= request.POST.get('barrio')))  
    propiedad_intance.save()
    for filename in request.FILES.iteritems():
        name = request.FILES[filename].name
        print('name =' + name)  ## <-- not printing anything
        print('file = ' +  file)## <-- not printing anything
        print('filename = ' + filename)## <-- not printing anything
  ubicaciones = Ubicacion.objects.all()
  ctx = {'ubicaciones': ubicaciones}
  return render(request, 'main/add_modal.html', ctx)

HTML模板

<form method='post' action=''  enctype="multipart/form-data">
   <input name='imagen' type="file" multiple/>
   <button type='submit' class="btn waves-effect">Upload</button>
</form>

views.py是我现在拥有的那个，但是到目前为止，我已经尝试了以下所有变体：

**1**
if request.method == 'POST':
  for f in request.FILES.getlist('imagen'):
    filename = f.name
    print(filename) ## <-- not printing anything

**2**
if request.method== 'POST':
  form = FileUploadForm(request.POST, request.FILES) ## form imported from forms.py
  if form.is_valid():
     print('form is valid!') ## <-- not printing anything
  else:
     print('form not valid ') ## <-- not printing anything either!! IDK WHY
**3**
if request.method == 'POST':
  print('request.method = "POST" checked ') # <-- Not priting anything! but the model below is being saved to the database! my brain is about to explode right now haha.
  propiedad_instance = Propiedad(tipo = request.POST.get('tipo'), tamano=request.POST.get('tamano'), habitaciones = request.POST.get('habitaciones'), banos = request.POST.get('banos'), descripcion= request.POST.get('descripcion'), direccion= request.POST.GET('descripcion'), precio= request.POST.get('precio'), ubicacion= Ubicacion.objects.get(barrio= request.POST.get('barrio')))    
  propiedad_intance.save()
  files = request.FILES.getlist('imagen')
    if files:
        for f in files:
            print('something') #<-- not printing anything
            print(f) #<-- not printing anything
            print(f.name) <-- not printing anything
    else:
        print('nothing here') #<--- not printing anything

根据文档上传多个文件的正确方法是。

files = request.FILES.getlist('file_field') #'file_field' --> 'imagen' for you
if form.is_valid():
        for f in files:
            ...  # Do something with each file.

您的html看起来还不错。按照上面的内容替换您的视图代码，并检查视图代码是否符合POST的要求？

Django无法上传多个文件和request.FILES似乎为空
