处理上传图像django admin python [英] handling uploading image django admin python

问题描述

我正在Windows上使用Python Django开发一个应用程序我试图添加一个图像上传字段到我的一个类，但是我收到错误，我必须提到，我需要给一个相对路径的settings.py所以我可以轻松地将我的代码迁移到另一个平台上。

我应该如何在settings.py中填充以下变量，让他们工作。

  MEDIA_ROOT = #root到我的项目
 
 MEDIA_URL = #url 
  

在models.py中我有

  class ProdcutImage（models.Model ）
 product = models.ForeignKey（Product）
 image = models.ImageField（upload_to =/ products）
  

我需要将图像上传到此文件夹中：

 MY_PROJECT_ADDRESS / static /图像/产品
  

您的帮助将不胜感激

解决方案

我建议您按照这个答案

需要最小的Django文件上传示例

，最好是将您的上传文件转到不同于静态的目录，但如果要将其上传到此目录，请执行以下操作：

  class ProdcutImage（models.Model）：
 product = models.ForeignKey（Product）
 image = models.ImageField（upload_to =static / images / products ）
  

settings.py

  import os 
 PROJECT_ROOT = os.path.realpath（os.path.dirname（__ file__））
 
 MEDIA_ROOT = PROJECT_ROOT +'/ static / images / products / '
 MEDIA_URL ='/ media /'#put无论你想要什么，当url被渲染它将是/media/imagename.jpg 
  

和urls.py

  from django.conf.urls.static import static 
从django.conf导入设置
 
 
 + static（settings.MEDIA_U RL，document_root = settings.MEDIA_ROOT）#at the end 
  

I am developing an application with Python Django on Windows I'm trying to add an image upload field to one of my class but I get errors, I have to mention that I need to give a relative path to the settings.py so I can easily migrate my code to another platform

how should I fill the following variables in settings.py to get them work

MEDIA_ROOT = #root to my project

MEDIA_URL = #url 

And in the models.py I have

class ProdcutImage(models.Model):
    product = models.ForeignKey(Product)
   image = models.ImageField(upload_to = "/products" )

I need the images to be uploaded in this folder :

"MY_PROJECT_ADDRESS/static/images/products"

Your helps will be appreciated

解决方案

I suggest you to follow this answer

Need a minimal Django file upload example

and it is better that your upload file go to a different directory than static but if you want to upload it to this directory:

class ProdcutImage(models.Model):
    product = models.ForeignKey(Product)
   image = models.ImageField(upload_to = "static/images/products" )

settings.py

import os
PROJECT_ROOT = os.path.realpath(os.path.dirname(__file__))

MEDIA_ROOT = PROJECT_ROOT + '/static/images/products/'
MEDIA_URL = '/media/'  #put whatever you want that when url is rendered it will be /media/imagename.jpg

and in urls.py

from django.conf.urls.static import static
from django.conf import settings


+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)  #at the end
