I am new to the whole mod_wsgi and serving files through apache. I am really comfortable with flask but this is something i can't get my head around. I did the hello-world program and successfully displayed hello world! Now i wanted to display a image file. So I updated my hello-world.py to:
from flask import *
yourflaskapp = Flask(__name__)
@yourflaskapp.route("/")
def hello():
file="203.jpg"
return render_template("hello.html",file=file)
# return"HEY"
if __name__ == "__main__":
yourflaskapp.run()
my directory structure is something like:/var/www/hello-world
/hello-world
test.py
yourflaskapp.wsgi
/static
-203.jpg
/templates
-hello.html
My template is simple:
<!DOCTYPE html>
<html><head><title>hi</title></head>
<body>
<img src="{{url_for('static',filename=file)}}"/>
</body></html>
and my apache conf file is:
<VirtualHost *:80>
WSGIDaemonProcess yourflaskapp
WSGIScriptAlias / /var/www/hello-world/yourflaskapp.wsgi
Alias /static/ /var/www/hello-world/static
Alias /templates/ /var/www/hello-world/templates
<Directory /var/www/hello-world>
WSGIProcessGroup yourflaskapp
WSGIApplicationGroup %{GLOBAL}
Order deny,allow
Allow from all
</Directory>
<Directory /var/www/hello-world/static>
Order allow,deny
Allow from all
</Directory>
<Directory /var/www/hello-world/templates>
Order allow,deny
Allow from all
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
LogLevel warn
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
Though when i open the browser and head to my ip, it doesn't show the image file. What am i doing wrong? Is there any other approach i should follow? and if anyone could recommend any good links from where i can understand working with flask+mod_wsgi+apache2

It is generally always a good idea to have trailing slash balanced when mounting static files at a sub URL. So instead of:
Alias /static/ /var/www/hello-world/static
use:
Alias /static /var/www/hello-world/static
