Hi everybody,
I manually uploaded file via SQLFORM.factory too and the file has been
uploaded using the excerpt below :
forma = SQLFORM.factory(
Field("image_1", "upload", uploadfield=True,
uploadfolder=os.path.join(request.folder,'uploads/'), ...), ...,
table_name="imagebiens")
...
if forma.validate():
if forma.vars.image_1:
db.imagebiens.insert(**dict(image=forma.vars.image_1,
bienid=bien.id))
...
It works. I can find the file renamed in the uploads folder.
But now, I want to render the file in a view like this :
<p>
{{for sary in limagebien:}}
<img src="{{=URL("default", "download", args=sary.image)}}" width="96"
height="96">
{{pass}}
</p>
which is rendered in html like this :
<p> <img
src="/maloca/default/download/imagebiens.image_1.a8e26134c9014d3a.6372756e636862616e672e706e67.png

width="96" height="96"> <img
src="/maloca/default/download/imagebiens.image_1.b24410c2dae27017.6372756e636862616e672d666c616d65732d776964652d62792d6f6d6e732e6a7067.jpg

width="96" height="96"> </p>
The problem is that the image doesn't appear. The download action seems not
to be capable to render it. Has anyone an idea where in this code the
problem comes from?
Thanks in advance
