Hello Anthony,
I'll try to do according to the book but unfortunately it won't work.
import os
user_name = request.vars['user_name']
path_ = "/var/www-data/web2py/applications/app_name/uploads/%s" % user_name
db.define_table('media',
Field('user_name', 'string', length=30, required=True),
Field('file_name', 'string', length=30, required =True),
Field('file_', uploadfolder=path))
#uploadfolder=os.path.join(request.user_name, path))), 'upload')
Upload function in the controller
# Create folder(name it as username) upload file to that folder.
def upload_File():
if request.vars['user_name'] is not None:
user_name = request.vars['user_name']
file_name = request.vars['file_name']
row = db(db.driver.user_name==user_name).select().first()
path = "/var/www-data/web2py/applications/app_name/uploads/%s" %
user_name
if row is not None:
if not os.path.exists(path):
os.makedirs(path)
if request.vars['upload'] is not None:
uploadedFile = request.vars['upload']
inserted_id =
db.media.insert(user_name=user_name,file_name=file_name, file_=uploadedFile)
return "Inserted file ID: %s, folder created %s" %
(inserted_id, user_name)
return 'Username "%s" does not exist or file wasn\'t chosen' % user_name
if i user 'upload' file uploaded in the uploads folder (as it should) and I
can download file by clicking "file" link in the "Database db select" as
shown in the pic
But if I use:
import os
user_name = request.vars['user_name']
path_ = "/var/www-data/web2py/applications/app_name/uploads/%s" % user_name
db.define_table('media',
Field('user_name', 'string', length=30, required=True),
Field('file_name', 'string', length=30, required =True),
Field('file_', uploadfolder=path)) # or this ->
uploadfolder=os.path.join(request.user_name, path))),
In "database db select" changes file downloading link "file" as shown in
pic.:
is this therefore download function? if it is how should I modify it or
create new one? if not please redirect to the solution.
Thank you.
