Using my Django app, I'm able to read from the database just fine. When the application didn't have django sqlite3 attempt to write a readonly database to access the file, it gave me django sqlite3 attempt to write a readonly database error:. Which made sense. So I edited the permissions on the file, so that the Apache process had write permissions. However, instead of it being able to write, I get this cryptic error:.

Aha, just stumbled across an article explaining this, django sqlite3 attempt to write a readonly database.

Also Django have info on their NewbieMistakes page. The solution is to make sure the directory containing the database file also has write access allowed to the process. My solution to this was more like so. I didn't really want to change the ownership of this dir. mostly because i use the pi user to do things like git.

Instead of changing of permissions to www-data, i found that I only needed to change the permissions like this:. Note: if you have logging, you will need to do this for the django logfile as well or apache won't like it much. From the Django says "Unable to Open Database File" when using SQLite3 section of the Newbie mistakes Django wiki page django sqlite3 attempt to write a readonly database. Adding an operational user to the www-data group is working well on my test environment.

Additionally I've put the sqlite3. db file into a separate subfolderto be more secure. For Windows 7, 8. follow the Bonobo installation directions :.

The development server needs to be run as the same user who has write perms on the database folder, so if you originally created the database as root, you will need to be root when you run:.

should actually be chown www-data, django sqlite3 attempt to write a readonly database. otherwise there is some wizardy of chown command that I don't know about please enlighten me. I believe the extra dot is to set the group to the owner's default group. Otherwise it doesn't change the group. This is just from memory though, I highly recommend you try that out yourself. Summarized here in case of future link rot or tl;dr: SQLite3 wants write access to the DB file's directory so that it can create a journal file there when a transaction is opened.

Great for Linux users. Bupkiss for Windows. Show 3 more comments. db or whatever db you are using where pi is the user that i created all the files in. db sudo usermod -a -G pi www-data This gives group write access to the necessary files and adds the www-data user to the pi group.

setfacl sounds like a potentially good option. It would be good to have this listed as an instructional answer. One issue i face is that I need to delete the. db file often in testing. When it gets recreated, it needs to be chowned again. See my answer for this question, serverfault.

Is there something more I should add to that which would help? py is a full path make sure there are no special characters in the path on Windows, make sure the db directory path is written with double backslashes. edited Sep 18 '20 at fmalina 4 4 bronze badges. answered Jan 14 '10 at ssc ssc 1, 3 3 gold badges 15 15 silver badges 28 28 bronze badges.

py runserver. answered Dec 19 '11 at Kilizo Kilizo 1 1 bronze badge. While technically correct, running the server as root is a terrible idea -- It would be better to chown the database to the regular unprivileged user that normally runs the server db change owner for the subdirectory to www-data in debain or apache in centOS chown -R www-data db-folder and grab a cold beer coz your are done.
