Django can't get access to sqlite3 database

Nginx Ubuntu Security Django One-Click Install Apps Let's Encrypt

I am currently running a server instance of the one-click install option for Django Ubuntu 14.04.

This server is running a Django app using NGINX, sqlite3, and gunicorn.

I set up letsencrypt properly and it is used to serve my website with ssl.

I deleted all of the files in /home/django/dango_project/ and replaced them with my own.

When I load my website, everything works fine, except for my admin site.

I am able to log in to the admin site when I run the django_project locally, but it isn’t working when the project is in production at my website.

You can verify that my db.sqlite3 file exists and contains posts by going to kensch.com/blog.

With debug disabled, my website gives a Server Error (500) after I log in to my admin site.

With debug enabled, my website gives OperationalError at /admin/
attempt to write a readonly database after logging into the admin site.

I have been trying to get into my admin site for nearly 5 hours now, no google searches are helping.

I appreciate any help in advance!

open puTTy
once you link the ip address and login
cd into file location ie
cd /home/django/django_project/
then enter

chown django:django db.sqlite3

Hello,
Here my solution:

root@fiq:/home/django/django_project# chmod 777 db.sqlite3

root@fiq:/home/django/django_project# cd ..

root@fiq:/home/django# chmod 777 *

Go to <your_website/admin> put username and password.. That’s it.

      Try this.

      nano /etc/init/gunicorn.conf,

      change to :

      ’# If the process quits unexpectadly trigger a respawn
      respawn’

      *change to

      www-data django
      www-data django

      Hope this can help.

        Hi btlychee,
        Thanks for the follow up.
        I have the gunicorn.conf file open, and I see

        # If the process quits unexpectadly trigger a respawn
respawn

        But I don’t see 

        www-data django
www-data django

        In the file. You told me to “change to” two things, I’m not sure I understand what to change. Could you please be more specific as to what I should change?

        Again, I appreciate the help

The solution I found is very simple: you just need to add writing permission to the users of the database. Go to the folder of you db.sqlite3 and run chmod a+w db.sqlite3 to add writing permission for all users. Then run service gunicorn restart if the changes do not take effect. Worked for me.

I had the same problem which gave me a lot of headache but this small line of code ‘chmod a+w db.sqlite3’ performed the magic and it worked perfectly. Thank you santopolsky
