I'd like to give some advice before start your Django journey and Django project configurations

---------- Before Start Django ----------

1. master Python "class" bacause you might use django class-based view a lot, learn "decorator" and standard library "datetime" and "re"

2. choose "Python version" for your django project, I recommend Python 3.10 or 3.11. You should check current installed Python version

    in your terminal --> py --version

** if you use Unix OS like MacOS or Linux, type "python3" instead of "py"

3. I highly recommend create virtual environment for each django project, install virtualenv with pip

    windows cmd --> py -m pip install virtualenv

        then --> py -m virtualenv app-env

    macos terminal --> python3 -m pip install virtualenv

        then --> python3 -m virtualenv app-env

4. activate virtual environment you just created

    windows cmd --> app-env\Scripts\activate.bat   or   app-env\Scripts\activate

    macos terminal --> source/bin/activate

    to stop virtualenv just type --> deactivate

5. install django latest version via pip (you must activate virtualenv first)

    --> py -m pip install django

---------- Start Django ----------

1. start new django project (don't forget to activate virtualenv first)

    --> django-admin startproject my-app

2. go inside project folder and create "requirements.txt" and type all requirement library for your project

   --- requirements.txt ---

django >= 4.2.0, < 4.3.0

wheel >= 0.4.0

ipython >= 8.11.0                       # python shell for django project

python-decouple >= 3.7.0        # for hiding sensitive data in settings.py before uploading to git

setuptools >= 67.7.0

psycopg >= 3.0.0                       # postgresql database driver. if you use django 4.1 or lower you must install psycopg2 instead of psycopg

 mysqlclient => 2.1.1                # mysql database driver. if you already use postgresql you don't need this

3. install specified dependencies

    --> py -m pip install -r requirements.txt

    for upgrade your dependencies --> py -m pip install --upgrade -r requirements.txt

    by doing this you have more control to your project dependencies

    for example if you specified "django >= 4.2.0, < 4.3.0" it will upgrade django between 4.2.0 to 4.2.* but never 4.3.0

4. in your main project directory it will have 3 files now

    my-app,  manage.py  and  requirements.txt

5. open "settings.py" in "my-app"

    first thing you need to be cautious is SECRET_KEY constant. You must never lose it or expose this to public that's why "python-decouple" library needed

    for more information https://pypi.org/project/python-decouple/

6. in DATABASE section change it to your database

    --- for postgresql ---

DATABASES = {

'default': {

DATABASE_ENGINE='django.db.backends.postgresql'

DATABASE_NAME='mydatabase'

DATABASE_USER='root'

DATABASE_PASSWORD=''

DATABASE_HOST='localhost'

DATABASE_PORT='5432'

}

}

    --- for mysql ---

DATABASES = {

'default': {

ALLOWED_HOSTS='localhost'

DATABASE_ENGINE='django.db.backends.mysql'

DATABASE_NAME='mydatabase'

DATABASE_USER='root'

DATABASE_PASSWORD=''

DATABASE_HOST='localhost'

DATABASE_PORT='3306'

}

add your "user" and "password", both database port above are default port though

7. start your first database migrate

--> py manage.py migrate

Now go for Django Tutorial --> https://docs.djangoproject.com/en/4.2/

I hope this help you avoid some problems in the future.
