Question

当我上传文件时，我得到一个＆＃34; POST / submit / HTTP / 1.1＆＃34; 200 604.当我检查上传的文件是否无法找到时。

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)

形式：

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

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

查看：

 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
})

的url：

from django.conf.urls import url

from mysite.uploads  import views

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

模板：我使用的是multipart / form-data，不确定文件上传的原因。

 <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字段上收到错误但未在模板中呈现任何反馈以表明此情况。

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：

请注意，如果请求方法是POST，则request.FILES将仅包含数据，并且发布请求的请求具有属性enctype =＆＃34; multipart / form-data＆＃34;

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，它会显示错误。

Django文件上传不保存到文件系统
