Attempt to write a readonly SQLite database in Django - django

Question

I have implemented my simple Django applications on server, but my forms for users can not save anything.
My database settings looks like this:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
}
}
My error which template receives looks like this:
nvironment:

The above exception (attempt to write a readonly database) was the direct cause of the following exception:

Exception Value: attempt to write a readonly database
How can I add changes to get rid of an error? I found similar answers on Stack Overflow, but I did not find information on how to allow everyone to write changes to SQLite (to make the error disappear).

Answer 1

The first place that I would look for is whether or not the user who is running the Django app has write permissions on db.sqlite file.
