How do I display uploaded images from uploads folder

[Maurice Waka]

I'm trying to retrieve an uploaded image from the uploads folder using this example.

I keep on being redirected back to the index page.

I also tried this option with the same result.

This is the controller code:

def showarticle():
    id = request.args(0) or redirect(URL('default', 'index'))
    article = Article[id]
    try:    
        import os
        from PIL import Image
    except:
        return
    stream=Image.open(request.folder + 'uploads/' + id)
    return response.stream(stream, attachment=False, article=article)

How can I get this right?

Regards

Hi, looks like your request.args(0) is empty.

How are you generating the URL for showarticle()?

Also, I think you can just do an ordinary file open(), rather than having to import PIL and doing an Image.open()

BTW, I handle images as <IMG> tags, where src=showimg(id), and showimg() reads the file.  I also have an example, maybe previously posted, where I use download() instead of a custom showimg(),so the controller does a select on the upload table, and then

return dict(img=row.fdata)

and the view has

{{=IMG(_src=(URL"download", img), _alt="test image")}}

Good luck!

Also note that a file uploaded to an upload field is not stored with the name the user passed to the upload form; instead, it is stored with a mangled, er, obfuscated name, and to find the file you should expect to do a db query.  See Chapter 6 under Field Types.
