为什么我无法通过admin /？将jpg文件上传到我的Django应用程序？ [英] Why can't I upload jpg files to my Django app via admin/?

问题描述

我正在尝试在我的Django应用程序中添加图像到我的模型。

models.py

  class ImageMain（models.Model）：
 product = models.ForeignKey（Product）
 photo = models.ImageField（upload_to ='products'）
  

在开发模式下，每次我尝试通过Django管理员上传图像时，我一直在：

上传有效的图片。您上传的文件不是图像或
a损坏的图像。

我通过fink安装了libjpeg，然后安装了PIL 1.1 .6 on ox X 10.5.7

 从PIL导入图像
 file = open（'/ Users / Bryan / work / review_app / media / lcdtvs / samsung_UN46B6000_front.jpg'，'r'）
 trial_image = Image.open（file）
 trial_image.verify（）
  / pre> 
 
 
似乎jpg基于该会话有效。但是，它不加载。 
我尝试过其他jpg，他们也不工作。
 
 
 
可能会出错？
 
 
 
我能够成功上传一个png文件。
解决方案
在PIL已经编译/安装之后，是否安装了libjpeg系统？也许它找不到解码器？
 
 
 
这里有一组我在使用libjpeg和pIL在MacOS上播放的指令（看到最后，看起来像你可能需要明确设置解码器的目录）：

I'm trying to add images to my models in my Django app.

models.py
class ImageMain(models.Model):
  product = models.ForeignKey(Product)
  photo = models.ImageField(upload_to='products')
In development mode, every time I try to upload the image via Django admin, I keep getting:

  
Upload a valid image. The file you uploaded was either not an image or
  a corrupted image.
I installed libjpeg via fink and then installed PIL 1.1.6 on ox X 10.5.7
from PIL import Image
file = open('/Users/Bryan/work/review_app/media/lcdtvs/samsung_UN46B6000_front.jpg', 'r')
trial_image = Image.open(file)
trial_image.verify()
It seems that the jpg is valid based on that session. However, it does not load.
I have tried other jpgs, they don't work either.

What could be going wrong?

I was able to successfully upload a png file.
解决方案
Did you install libjpeg after PIL was already compiled/installed on the system? Maybe it can't find the decoder properly?

Here's one set of instructions I found on getting libjpeg and PIL playing nicely on MacOS (see towards the end; looks like you may need to explicitly set the dir of the decoder):
