    }
}

so i see the created thadb.db in my project folder,

i have the error:

Exception Value:    
unable to open database file

so I have $sudo chmod 777 thadb.db

but still get the same error,

is this because of the permission? should i set the folder to 777?

EDIT>>

As per suggested solution, i tried chmod root for the db and the root folder

-rwxrwxrwx 1 root     ubuntu   44032 2012-04-09 09:49 thadb.db
drwxrwxrwx 3 root   ubuntu 4096 2012-04-09 12:44 micopiloto

Still not working! ;(

i get this error:

Exception Value:    
unable to open database file

So how to make the admin show??

how will the security be affected?

thanks!

works for me. Try to let www-data write in database directory to let sqlite create the journal file.

ok, after much grappling got it to worked, so if another noob haves this problem this is part of the solution[ with making the db file n folder for the db with the right permissions]

the problem was the path for my db on the settings.py

i gave the whole path and then it worked ;)
