I'm trying to send an image to the client, so i have this function in
my controller:
def Photo_Test(self):
from PIL import Image
from StringIO import StringIO
f=open("test.jpg","rb")
data=f.read(1000000)
response.headers["content-type"]="image/jpeg"
response.write(data)
return response
The test.jpg file is just a tiny test jpeg. When I run "paster serve --
reload development.ini" and go to the page that would execute this
function paster just quits, and the browser is left with an empty
page.
Running "paster shell" and then the command "app.get("/main/
Photo_Test")" results in the following traceback:
>>> app.get("/main/Photo_Test")
Traceback (most recent call last):
