Django 文件上传不保存到文件系统

Question

当我上传文件时，我收到 "POST /submit/ HTTP/1.1" 200 604。当我检查是否已上传文件时，我找不到它。

设置文件包括：

 BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
 MEDIA_URL = '/media/'
 MEDIA_ROOT = os.path.join(BASE_DIR, 'media')

型号：

 from django.db import models 

 class Document(models.Model):
    description = models.CharField(max_length=255, blank=True)
    document = models.FileField(upload_to='documents/')
    uploaded_at = models.DateTimeField(auto_now_add=True)

表格：

from django import forms
from mysite.uploads.models import Document

class DocumentForm(forms.ModelForm):
    class Meta:
        model = Document
        fields = ['description', 'document']

 from django.shortcuts import render
 from django.http import HttpResponseRedirect
 from django.core.urlresolvers import reverse

 from mysite.uploads.models import Document
 from mysite.uploads.forms import DocumentForm

def model_upload(request):
    if request.method == 'POST':
        form = DocumentForm(request.POST, request.FILES)
        if form.is_valid():
            form.save(commit=True)
            return HttpResponseRedirect(reverse('uploadindex'))
   else:
       form = DocumentForm()
   return render(request, 'uploads/index.html', {
    'form': form
})

网址：

from django.conf.urls import url

from mysite.uploads  import views

urlpatterns = [
    url(r'^$', views.model_upload, name='uploadindex'),
]

模板：我正在使用 multipart/form-data，不确定为什么文件无法上传。

 <html>
    <body>
    <form action="{% url "uploadindex" %}" 
       method="post"encytpe="multipart/form-data">
       {% csrf_token %}
       {{ form.as_p }}
       <button type="submit">Upload</button>
    </form>
    </body>
 </html>

Answer 1

我的猜测是您的 DocumentForm 无效，并且您在 document 字段中收到错误但未在模板中呈现任何反馈来指示这一点。

检查您是否在表单标记上设置了适当的编码。这是通过 Django 表单处理文件上传的最常见问题：

Note that request.FILES will only contain data if the request method was POST and the that posted the request has the attribute enctype="multipart/form-data"

https://docs.djangoproject.com/en/1.11/topics/http/file-uploads/#basic-file-uploads

Answer 2

...
if form.is_valid():
        form.save(commit=True)
        return HttpResponseRedirect(reverse('uploadindex'))
else:
    print form.errors
...

如果您的 document 字段有任何错误，它将向您显示错误。
