Question

我是django的新手并试图解决这个问题，但是找不到它的错误。表单的所有验证都完美地传递，但图像实际上并未上传到媒体根目录。我试图显示图像，我只获得图像图标而不是图像。

设置根部分：

STATIC_ROOT = os.path.join(BASE_DIR, 'Vote','static')
STATIC_URL = '/static/'

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

模型代码：

class Vote(models.Model):
    name = models.CharField(max_length=50)
    image = models.ImageField(upload_to= "images/vote/")
    rating = models.IntegerField(default=0)
    vote_type = models.ForeignKey(VoteType)

    def __unicode__(self):
        return self.name

views.py创建（查看）代码：

def create(request):
    class RequiredFormSet(BaseFormSet):
        def __init__(self, *args, **kwargs):
            super(RequiredFormSet, self).__init__(*args, **kwargs)
            for form in self.forms:
                form.empty_permitted = False
    VoteFormSet = formset_factory(VoteForm, max_num=10, formset=RequiredFormSet)
    if request.method == 'POST': # If the form has been submitted...
        vote_list_form = VoteTypeForm(request.POST) # A form bound to the POST data
        vote_list_form.pub_date = timezone.now()
        # Create a formset from the submitted data
        vote_item_formset = VoteFormSet(request.POST, request.FILES)
        if vote_list_form.is_valid() and vote_item_formset.is_valid():
            vote_list = vote_list_form.save()
            for form in vote_item_formset.forms:
                vote_item = form.save(commit=False)
                vote_item.vote_type = vote_list
                print vote_item.vote_type
                vote_item.save()
            return HttpResponseRedirect('created/%s' %vote_list.id) # Redirect to a 'success' page
    else:
        vote_list_form = VoteTypeForm()
        vote_item_formset = VoteFormSet()
        vote_list_form.pub_date = timezone.now()

    c = {'vote_form': vote_list_form,
         'vote_item_formset': vote_item_formset,
        }
    c.update(csrf(request))

    return render_to_response('Vote/create.html', c)

还有模板代码（非常庞大，不确定是否需要）：

enter image description here 当我使用创建视图创建文件时，它不会将图像上载到media / images / vote。为什么会这样？

编辑1：添加了一些代码有人还告诉我，我应该将其添加到我的代码

 if settings.DEBUG:
    urlpatterns += patterns('',
        url(r'^media/(?P<path>.*)$', 'django.views.static.serve', {
            'document_root': settings.MEDIA_ROOT,
        }),
    )

现在的问题是，当我尝试获取图像时，程序会在以下位置查找图像：

"GET /Vote/216/voting/images/vote/background_OeAkutY.gif/ HTTP/1.1" 404 3135

我认为他从我的urls.py文件中获取。但我不明白为什么程序在/投票/ ID /投票...而不是MEDIA_ROOT。或者GET并不意味着它正在寻找那个地方吗？

这是我的投票/网址：

urlpatterns = [
    #url(r'^$', views.IndexView.as_view(), name='index'),
    url(r'^$', views.index, name='index'),
    url(r'^(?P<pk>[0-9]+)/results/$', views.results, name='results'),
    url(r'^(?P<pk>[0-9]+)/voting/$', views.voting, name='voting'),
    url(r'^create/$', views.create, name='create'),
    url(r'^create/created/(?P<pk>[0-9]+)/$', views.created, name='created'),
]

Answer 1

根据媒体文件的路径更改MEDIA_ROOT：
例如。 C：\用户\ Vato \ PycharmProjects \项目3 \投票\媒体

使用Django
