This is the above error I am getting when I am trying to write an xml
file in
TESTIMONIAL_DIR /home/erp/webapps/erp_dev/erp/xml/testimonial'

It something related to permission stuff. I did chmod 777 on both
xml and testimonial folder which I created. Still getting the same
issue. Can you please help me there.

Scenerio is I need to generate xml file from the form field and put
it in to that TESTIMONIAL folder.

my code in views.py

filename = fname + "_" + lname + ".xml"
filepath = settings.TESTIMONIAL_DIR + "/" + filename;
logging.debug('filepath = %s' % filepath)

FILE = open(filename,"w") ----- This is the line its giving the
error.
doc.writexml(FILE)
FILE.close()

Thank you
Bhaskar
