Django STATIC_URL 为空，图像不显示 [英] Django STATIC_URL is empty, images doesn't show

问题描述

我知道有很多这样的问题，我阅读了所有问题并尝试了所有方法，但没有解决我的问题.

I know that there is plenty of questions like that, I read them all and tried everything, however nothing solved my problem.

我正在用 Django 写博客之类的东西，当然我想向用户展示图片.图片存储在 /static/users//.

I'm writing something like blog in Django and of course I want to show pictures to users. Pictures are stored at /static/users/<username>/<image>.

我的setting.py

    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, 'templates')]

        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [

我在 html 中有什么

What I have in html

 {% load static from staticfiles %}
 <img src="{% static comment.author.picture.url %}"
                                         width="70px" height="70px">

以及我的观点

@login_required
def trip_one(request, pk):
    trip = get_object_or_404(Trip, pk=pk)
    if request.method == 'POST':
        form = CommentForm(request.POST)
        if form.is_valid():
            cd = form.cleaned_data
            user = Person.objects.get_by_natural_key(request.user.get_username())
            comment = Comment(text=cd['text'],
                              author=user,
                              trip=trip)
            comment.trip = trip
            comment.save()
    comments = trip.comment_set.all()
    form = CommentForm()
    return render(request, 'TravelBuddy/travel.html', {'trips': trip,
                                                       'form': form,
                                                       'comments': comments})

我在浏览器中的图片链接是这样的

And my link to images in browser looks like this

http://127.0.0.1:8000/users/default/default.png

当他们必须看起来像这样

When they have to look like this

http://127.0.0.1:8000/static/users/default/default.png

我不能只将 static 添加到 html 中的 url，因为它在其他页面上不起作用.

I cant just add static to url in html because it doesn't work on other pages.

那么，我错过了什么?或者这里有什么问题?

So, what I am missing? Or what is wrong here?

推荐答案

在这种情况下，您似乎需要引用 MEDIA 而不是 STATIC.

It appears that you need to refer to MEDIA instead of STATIC in this case.

查看设置中的 MEDIA_ROOT 和 MEDIA_URL 以确保它们指向正确的位置.

Take a look at your MEDIA_ROOT and MEDIA_URL in settings to ensure they're pointed to the right place.

然后，在您的模板中，您可以通过属性获取对象的 URL:

Then, in your template, you can get the URL for the object via the attribute:

<img src="{{ comment.author.picture.url }}" width="70px" height="70px">

文档中有关 MEDIA 的更多信息:https://docs.djangoproject.com/en/1.9/ref/settings/#std:setting-MEDIA_ROOT
