我使用的是inlineformset,以便用户可以一次上传多张图片。图像被保存和功能是如预期,除了在前端侧。当我依次通过我的表单集用类似的方法{{形式。图像}},我可以清楚地看到我的形象被保存,当我点击链接,我重定向到上传的文件。这个问题似乎是在absoulte网址不被存储时,我尝试把图像的URL作为图像元素的SRC。
尝试登录MEDIA_URL和MEDIA_ROOT在<p>
标签产生任何结果。

同样,当我尝试:
<img src="{{ MEDIA_URL }}{{ gallery_form.image.url }}">
我得到的“未知”作为源的价值,但我可以点击链接“{{gallery_form.image}}”生成并查看已上传的图像。试图登录这两个“MEDIA_URL”和“MEDIA_ROOT”产生任何结果。不太清楚其中的问题所在。
无需图像的地址之前添加{{MEDIA_URL}}
。因为默认情况下它会你的图片的URL路径前添加/media
。
此外,一定要所有的路径开始media
添加到您的网址。
from django.conf import settings
if settings.DEBUG:
urlpatterns += patterns('',
(r'^media/(?P<path>.*)$', 'django.views.static.serve', {
'document_root': settings.MEDIA_ROOT}))
还尝试打印在Django模板图像URL时,处理该图像不存在这样的情况:
<img src="{% if gallery_form.image %}{{ gallery_form.image.url }}{%else%} <default-image-path-here> {%endif%}"
使用<img src="{{ gallery_form.image.url }}">
并确保image
不None
在urls.py
加入这一行
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
虽然我不明白,为什么我不能使用的.url()方法Django的预定义了,我也不过,最终使用在我的前面的问题向我提出另一种解决方案用户。基本上,用户已经上传的图片,我们让他们存储在一个数据库后,我们做一个变量存储这些图像的URL属性,并从模板访问该变量。它看起来是这样的:
views.朋友
selectedUserGallery = Gallery.objects.filter(user=user) # Get gallery objects where user is request.user
userGallery_initial = [{'image': selection.image, 'image_url':selection.image.url} for selection in selectedUserGallery if selection.image]
if request.method == "GET":
print("--------GET REQUEST: PRESENTING PRE-EXISTING GALLERY IMAGES.-------")
profile_form = ProfileEditForm(request.user)
gallery_inlineformset = galleryInlineFormSet(initial=userGallery_initial)
template.html
<form id="post_form" method="POST" action='' enctype='multipart/form-data'>
{% csrf_token %}
{{ gallery_inlineformset.management_form }}
{% for gallery_form in gallery_inlineformset %}
<div class="link-formset">
{{ gallery_form.image }} <!-- Show the image upload field, this is not he image var from views.py -->
{% if gallery_form.image is not None %}
<p>The image should be below:</p>
<img src="{{ gallery_form.initial.image_url }}">
{% endif %}
</div>
{% endfor %}
<input type="submit" name="gallery-submit" value="Submit" />
</form>
另外,我最终取代了大部分的代码从原来的岗位作为我不再使用bulk_create()。
