Django -模型:保存文件
Django -模型:保存文件
提问于 2015-01-22 19:05:56
我正在尝试制作一个django-ajax上传器来创建一个模型。我已经创建了一个示例，但我无法理解是否需要使用import_uploader或创建一个简单的类来保存带有文件的模型。如果我这样做，我不知道AJAX操作是否会被禁用。
urls.py
from django.conf.urls import patterns, include, url
# Uncomment the next two lines to enable the admin:
# from django.contrib import admin
# admin.autodiscover()
urlpatterns = patterns('',
# Examples:
# url(r'^$', 'bft.views.home', name='home'),
# url(r'^bft/', include('bft.foo.urls')),
# Uncomment the admin/doc line below to enable admin documentation:
# url(r'^admin/doc/', include('django.contrib.admindocs.urls')),
# Uncomment the next line to enable the admin:
# url(r'^admin/', include(admin.site.urls)),
url(r'start$', 'bbb.views.start', name="start"),
url(r'ajax-upload$', 'bbb.views.import_uploader', name="my_ajax_upload"),
)views.py
from django.middleware.csrf import get_token
from django.shortcuts import render_to_response
from django.template import RequestContext
from ajaxuploader.views import AjaxFileUploader
def start(request):
csrf_token = get_token(request)
return render_to_response('import.html',
{'csrf_token': csrf_token}, context_instance = RequestContext(request))
import_uploader = AjaxFileUploader()
# Create your views here.import.html
<!doctype html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js" ></script>
<script src="{{ STATIC_URL }}ajaxuploader/js/fileuploader.js" ></script>
<link href="{{ STATIC_URL }}ajaxuploader/css/fileuploader.css" media="screen" rel="stylesheet" type="text/c$
<script>
$(function(){
var uploader = new qq.FileUploader({
action: "/ajax-upload",
element: $('#file-uploader')[0],
multiple: true,
onComplete: function(id, fileName, responseJSON) {
if(responseJSON.success) {
alert("success!");
} else {
alert("upload failed!");
}
},
onAllComplete: function(uploads) {
// uploads is an array of maps
// the maps look like this: {file: FileObject, response: JSONServerResponse}
alert("All complete!");
},
params: {
'csrf_token': '{{ csrf_token }}',
'csrf_name': 'csrfmiddlewaretoken',
'csrf_xname': 'X-CSRFToken',
},
});
});
</script>

首先，我建议您使用模型FILEFIELD创建一个模型来存储文件的信息和url：
设置您的媒体文件，文件将在何时存储Setting.py
MEDIA_ROOT = os.path.join(BASE_DIR,'media')
MEDIA_URL = '/media/'models.py
from django.core.files.storage import default_storage
...
class UploadFile(models.Model):
file = models.FileField(upload_to='docs/')Forms.py：
class UploadForm(forms.ModelForm):
documento = forms.FileField(label='Seleccione un archivo',
help_text='Max Size 2mb'
)
class Meta:
model = UploadFileviews.py：
def UploadView(request):
if request.method == 'POST':
form = UploadForm(request.POST,request.FILES)
if form.is_valid():
form.save()
return HttpResponseRedirect('/index/')
else:
form = DocuForm()
return render_to_response("yourtemplate.html",
{'form':form},
context_instance=RequestContext(request))我在一个表中显示文档列表，其中可以单击文件的名称并下载它。如果要启用文件的下载，请以这种方式更改您的urls.py：
urlpatterns = patterns('',
# Examples:
# url(r'^$', 'kp.views.home', name='home'),
# url(r'^blog/', include('blog.urls')),
url(r'^upload/$', 'kms.views.UploadView', name='upload'),
)+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
