问题描述

我正在尝试使用Django表单上传文件，并将这些文件保存在数据库本身中.我已经能够将文件的链接保存在数据库中，并将文件本身保存在我在Media_root中指定的目录中.

I am trying to upload files using django forms and save those files in the database itself.I have been able to save the link of the file in database and save the file itself in a directory which i specified in Media_root.Can you please help me and tell me what can i change in my code so that files are saved in the database.

这是我的代码:

from django.db import models


class Document(models.Model):
    docfile = models.FileField(upload_to='documents/%Y/%m/%d')

forms.py

Django导入表单中的

forms.py

from django import forms

class DocumentForm(forms.Form):
    docfile = forms.FileField(
        label='Select a file',
    )

views.py

来自django.shortcuts的

views.py

from django.shortcuts import render_to_response
from django.template import RequestContext
from django.http import HttpResponseRedirect
from django.core.urlresolvers import reverse
from .models import Document
from .forms import DocumentForm

def list(request):
    # Handle file upload
    if request.method == 'POST':
        form = DocumentForm(request.POST, request.FILES)
        if form.is_valid():
            newdoc = Document(docfile = request.FILES['docfile'])
            newdoc.save()

            # Redirect to the document list after POST
            return HttpResponseRedirect(reverse('upload.views.list'))
    else:
        form = DocumentForm() # A empty, unbound form

    # Load documents for the list page
    documents = Document.objects.all()

    # Render list page with the documents and the form
    return render_to_response(
    'list.html',
    {'documents': documents, 'form': form},
    context_instance=RequestContext(request)
    )

def index(request):
    return render_to_response('index.html')

django.conf.urls中的

from django.conf.urls import patterns, include, url
from django.conf import settings
from django.conf.urls.static import static
from django.views.generic import RedirectView
from django.contrib import admin
# admin.autodiscover()

urlpatterns = patterns('',
        (r'^upload/', include('upload.urls')),
        (r'^$', 'upload.views.index'),
        (r'^admin/', include(admin.site.urls)),) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

project \ urls.py

django.conf.urls中的

project\urls.py

from django.conf.urls import patterns, include, url

urlpatterns = patterns('upload.views',
    url(r'^$', 'list', name='list'),
    url(r'^list/$', 'list', name='list'),)
