Django ImageField upload_to path
提问by user3025403
I'm having trouble understanding and using Django's ImageField.
我在理解和使用 Django 的 ImageField 时遇到问题。
I have a model:
我有一个模型：
class BlogContent(models.Model):
title = models.CharField(max_length=300)
image = models.ImageField(upload_to='static/static_dirs/images/')
description = models.TextField()
My file system is currently:
我的文件系统目前是：
src
|---main_project
|---app_that_contains_blog_content_model
|---static
|---static_dirs
|---images
When I run the server and go to the Admin page, I can add BlogContent objects. After choosing an image for the image field, the image has a temporary name. However, after I save this object I can't find the image in the folder specified by the upload_to path.
当我运行服务器并转到管理页面时，我可以添加 BlogContent 对象。为图像字段选择图像后，图像具有临时名称。但是，保存此对象后，在upload_to 路径指定的文件夹中找不到该图像。
What is the correct way to do this?
这样做的正确方法是什么？

Your image would be uploaded to mediafolder, so it's better change path in model like images/, and they will be upload to media/images
您的图像将被上传到media文件夹，因此最好在模型中更改路径，例如images/，它们将被上传到media/images
In settings.pyadd this
在settings.py添加这个
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
In url.py
在 url.py
from django.conf.urls.static import static
from django.conf import settings
urlpatterns = [....
]+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
And then, if you want to display all this image, use something like this
in view.pyBlogContent.objects.all()
然后，如果您想显示所有这些图像，请在 view.pyBlogContent.objects.all()
And render it like this:
并像这样渲染它：
{% for img in your_object %}
<img src="{{ img.image.url }}" >
{% endfor %}

staticin upload_todoesnot make sense, since user-uploaded images go into media/folder.. you need these:
static在upload_to没有意义，因为用户上传的图像进入media/文件夹..你需要这些：
image = models.ImageField(upload_to='blog/%Y/%m/%d')
and all images land in:
并且所有图像都位于：
media/blog/2016/01/02/img_name.jpg
you access it in template like this:
您可以像这样在模板中访问它：
<img src="{{ blog.image.url }}">
in settings:
在设置中：
import os
BASE_DIR = os.path.dirname(os.path.dirname(__file__))
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
