Remove Database settings of django using bash script - django

Question

I am trying to create a bash script to create a boilerplate django project that suits for my company. I need to delete the DATABASES in settings and append new one.
The DATABASES is a python dictionary with structure
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
}
}
For this I tried something like this
sed -i -e "/DATABASES = {/,/}/d" settings.py
But it resulted in a trailing }.
The output is
}
I understood that the pattern it matches is for the first curly braces but not the second. What should be the approach for this.

Answer 1

Why not just append a new DATABASE Configuration at the end of settings? It will automatically override previous DATABASE configuration. I use like this:
DBCONIG="DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': '${dbName}',
'USER': '${dbUName}',
'PASSWORD': '${dbPass}',
'HOST': '127.0.0.1',
'PORT': '3306',
}
}"
echo $DBCONIG >> settings.py
Here I collection dbName, dbUName etc from shell input.
For cleaner implementation approach, I keep a local_settings.py which has user machine specific setups. Inside in local_settings.py, I put the user's DB configurations. and I import this file in settings.py like this:
try:
from .local_settings import *
except:
pass
Also, I usually put local_settings.py file in .gitignore, so that these settings are not pushed to repository.
