Question

我的网站具有以下文件结构：

MyProject
 +--- media
       +--- user_1
             +--- my_image
 +--- profiles
       +--- templates
             +--- profiles
                   +--- create.html
                   +--- login.html
                   +--- profile.html
       +--- urls.py
       +--- models.py
       +--- views.py
 +--- MyProject
       +--- settings.py

在settings.py中，我设置了MEDIA_ROOT = os.path.join(BASE_DIR, 'media')和MEDIA_URL = '/'，我将'django.template.context_processors.media'添加到context_processors。在我的urls.py中，我有以下内容：

urlpatterns = [
    url(r'^profile/(?P<profile_id>[0-9]+)/$', views.Details, name = "account"),
    url(r'^update/', views.Update_Profile, name = "update"),
] + static(settings.STATIC_URL, document_root = settings.STATIC_ROOT) +\
    static(settings.MEDIA_URL, document_root = settings.MEDIA_ROOT)

模板profile.html如下所示：

{% extends "base.html" %}
{% load profiles_extras %}

{% block content %}
{% load staticfiles %}
<div class="container-fluid">
  <div class="row">
    <div class="col-lg-8 col-lg-offset-2">

      <!-- Store Information -->
      <div class="col-lg-6">
        <div class="panel panel-default">
          <div class="panel-heading">
            <h2>Store Information</h2>
          </div>
          <div class="center-block">

            <!-- Change picture form -->
            <form method="post" action="{% url 'update' %}" class="hidden form-inline" id="picture-change-form" enctype="multipart/form-data">
              {% csrf_token %}
              <div class="form-group">
                <input type="file" class="form-control" name="picture" accept="image/*">
              </div>
              <button type="submit" class="btn btn-default">Submit</button>
            </form>

            {% if profile.logo %}
              <img src="{{ profile.logo.url }}" class="img-responsive" id="logo" alt="Store Logo">
            {% else %}
              <img src="{% static 'no-image.png' %}" class="img-responsive" id="logo" alt="Store Logo">
            {% endif %}
          </div>
        </div>
      </div>
    </div>
  </div>
</div>
{% endblock %}

上传个人资料图片时，会调用profiles.views.py中的此功能。

@login_required
def Update_Profile(request):
    update_profile = Profile.objects.get(user = request.user)
    has_updated = False
    if ('picture' in request.FILES):
        update_profile.update_logo( request.FILES['picture'] )
    return redirect('profiles.views.Details', profile_id = update_profile.id)

此功能依次调用update_logo中的profiles.models.py：

def update_logo(self, value):
    self.logo = value
    self.save()

但是，当我上传照片时，my_image.png会显示为user_1/my_image.png，服务器会返回404，因为找不到该文件。我在这里做错了什么？

Answer 1

Django定义了/profile/，/update/，/static/和/的网址。

未定义网址/user_1/。

尝试将MEDIA_URL更改为/media/。

django无法找到图片
