Remove Database settings of django using bash script

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.

#django #linux #bash

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.

**Read More : **How to make Chatbot in Python.

Read More : Django Admin Full Customization step by step

let’s just get into this diagram that I made so in here:

django queries aboutDescribe each parameter in Django querset

we’re making a simple query for the myModel table so we want to pull out all the information in the database so we have this variable which is gonna hold a return value and we have our myModel models so this is simply the myModel model name so whatever you named your model just make sure you specify that and we’re gonna access the objects attribute once we get that object’s attribute we can simply use the all method and this will return all the information in the database so we’re gonna start with all and then we will go into getting single items filtering that data and go to our command prompt.

Here and we’ll actually start making our queries from here to do this let’s just go ahead and run** Python manage.py shell** and I am in my project file so make sure you’re in there when you start and what this does is it gives us an interactive shell to actually start working with our data so this is a lot like the Python shell but because we did manage.py it allows us to do things a Django way and actually query our database now open up the command prompt and let’s go ahead and start making our first queries.

How to Run bash scripts Using Python?

If you are using Linux, then you would definitely love the shell commands.

And if you are working with Python, then you may have tried to automate things. That’s a way to save time. You may also have some bash scripts to automate things.

Python is handy to write scripts than bash. And managing Python scripts are easy compared to bash scripts. You will find it difficult to maintain the bash scripts once it’s growing.

But what if you already have bash scripts that you want to run using Python?

Is there any way to execute the bash commands and scripts in Python?

Yeah, Python has a built-in module called subprocess which is used to execute the commands and scripts inside Python scripts. Let’s see how to execute bash commands and scripts in Python scripts in detail.
