* Create a  python virtual environment (have a virtual environment enabled)
windows - `python -m venv myenv`

* install Dependencies: pip install django, pip install pyscopg2(to interact with Postgress DB),
* after intstallation of this packages, create a new django project using `django-admin startproject financialData`

* cd finacialData, go to settings.py and change the database setting to suit postgresql pattern.
* Create postgres DB on `AWS RDS` (that's what we are going to use to connect our django project to our postgres database)
*Create yoir models in the models.py file. That's define database model for the stock data

* After models definiation runmigrations to integrate changes . `python manage.py  makemigrations stocs`
`python manage.py migrate`

* Go to Apha Vantage API documentation and get a free API `https://www.alphavantage.co/support/#api-key.`
* store API key in a 	`dotenv` file

* Create `services.py` file in the stock app. this is where the business logic for interacting with Alpha Vantage API will be written.

* Use the API key provided  and the url to fetch stock data in the `fetch_stock_data` function in stocks app.

*Now in our `views.py` we are going to create a Django view which would allow for fetching 
of  stock data.  The  `fetch_stock_data()`  in `services.py` would be triggered from this view.
 
* in `urls.py` under  stocks folder. The url path for the view we created wll be define. 
This would allow endpoint access and trigger data fetching. By calling the `as_view()` method
Django converts the CBV(class base view) into function-based view that can handle requests.

* Update the main project urls.py to ass App's url

* Add API key to `settings.py`, install  `python-dotenv` to load dotenv variables to settings


* Create a django superuser using `python manage.py createsuperuser` and then after that you can run the server using the 
command  `python manage.py runserver`













<------HARD LESSONS LEARNT----->
* Econter unable to resove AWS postgresql host name, due to different version of the psycopg2 package installed in my virtual environment.
Solution: Uninstall both packages `pip uninstall psycopg2`  and then intsall the desired version for it to work
