pppconverter's Issues

Show the year that's used for both countries.

Currently, we're taking the latest year available for each country. Need to show the years that's used to calculate along with the results.

The calculation seems to be wrong

Hi @nigelbabu

I wanted to check what formula are you using to calculate the To_country salary based on the PPP data by world bank and I got this formula from your code

var equivalent_salary = (Number(salary) / from_country_data.ppp) * to_country_data.ppp;

https://github.com/nigelbabu/pppconverter/blob/554f2332c561aab35647a78b7b9cdd67219fe977/static/js/app.js

Based on which if I do the same calculation in excel as shown below

whereas the result by your tool using the same formula show

_Can you please check and tell me if I am doing something wrong ? _

Show a table

Show a table instead of just one country, so all countries can be checked. Most often people are curious rather than looking for specific information.

How to setup up the db?

No guideline on how to set up the DB.
Running the server using manage.py doesn't create the DB with the schema.

Add instructions for setup and updating data

There are no instructions on how to set this up, which means I often forget how to do it.

NaN.N amounts

Using your currency converter at http://salaryconverter.nigelb.me, I tried to convert $100,000 into UKP. The result was:

In United Kingdom, NaN.N GBP will allow you to buy the same things you'd buy with NaN.N USD in United States.

Argentina country is missing and environment setup doesn't work

Missing Argentina is probably related to requiring newer data import. I followed the instructions to set up a local environment and update the CSV data in order to check Argentina. The process seems to have been successful from the commands' output, but it doesn't work. Whenever I go to http://127.0.0.1:5000/ I get an error logged to the terminal:

Updating data doesn't work

The instructions for updating the data no longer works — the ZIP file downloaded from World Bank portal contains three .csv files, all of which create a zero-sized parsed_data.csv.

New PPP Calculator based on latest OCED data

Greetings.

I appreciate this converter, But since this converter is not maintained anymore and that several countries were not included I have built my own PPP Calculator based on latest OCED data.

You're all welcomed to use and contribute towards improving it.
