Introduction
The main plan was to develop a COVID-19 tracker in Django that shows local data in the Philippines - until the Department of Health hid and disabled page where the stats can be scraped.
I did some crowdsourcing on Facebook and everyone shared a photo of the daily stats per city - which wasn't what I expected - but it was my fault, my question wasn't clear.
Coding
I already have experience in playing with API's so I thought it would be easier now since I could just use my code as a reference.
I found Chris Michael's from google and found it easy to use. The API returned:
{
"report":
{
"country":"philippines",
"flag":"https://www.worldometers.info/img/flags/small/tn_rp-flag.gif",
"cases":7579,
"deaths":501,
"recovered":862,
"active_cases":[],
"closed_cases":[]
}
}
The data isn't complete but that was fine. So in calling and using the API, I ended up with:
api.py
import requests
def get_data():
url = "https://covid19-server.chrismichael.now.sh/api/v1/ReportsByCountries/philippines"
headers = {'Accept': 'application/json'}
r = requests.get(url, headers=headers)
stat = r.json()
stat_data = {
'stat': stat['report']
}
return stat_data
Which was pretty much the same as my first API experience:
{% link https://dev.to/highcenburg/a-python-program-which-tweets-from-the-icanhazdadjokecom-api-3197 %}
Although this was not my first time using an API in Python, this was, however, my first time integrating an API with Django. I ended up with:
views.py
...
from django.views.generic import ListView
from covid_virus_tracker.users import api
...
class HomeView(ListView):
def get(self, request):
stat_data = api.get_data()
return render(request, 'pages/home.html', stat_data)
However, the api.py was registering as a python module and I honestly had a hard time figuring out why. Until I peeked into the source code and figured out that when importing in cookiecutter-django, you've to start from the project, down to the app, then to the file, if coming from another app.
Ex: from project_name.users.models import view
Then on the pages/home.html, all I had to do was:
{{ stat.recovered}} {{ stat.cases }} {{ stat.deaths }}
However, I felt like the site needed something more. I felt like I had to let the users know what's happening all over the world, so I integrated an API that scrapes blogs with a COVID-19 keyword. I found RapidAPI, which I had an account already, and found the contextualsearch API. The API returned:

Integrating was easier now since I've done it on the api.py. I ended up with:
import requests
import environ
env = environ.Env()
def get_data():
url = "https://contextualwebsearch-websearch-v1.p.rapidapi.com/api/Search/NewsSearchAPI"
querystring = {"autoCorrect": "false", "pageNumber": "1", "pageSize": "10", "q": "covid", "safeSearch": "true"}
headers = {
'x-rapidapi-host': "contextualwebsearch-websearch-v1.p.rapidapi.com",
'x-rapidapi-key': env("x-rapidapi-key"),
}
r = requests.get(url, headers=headers, params=querystring)
data = r.json()
article_data = {
'data': data['value']
}
return article_data
Notice that one difference is having to import environ and creating an env = environ.ENV() variable. I need this to hide my API keys and this is how cookiecutter-django hides it. All I had to do was place the keys in the .envs/local/.django & .envs/production/.django and I was good to go.
The views.py is:
...
from django.views.generic import ListView
from covid_virus_tracker.users import services
...
class IndexData(ListView):
def get(self, request):
article_data = services.get_data()
return render(request, 'pages/news.html', article_data)
On the pages/news.html, all I needed to do was loop through the data to show it. Like this:
{% for item in data %}
{{ item.title }}
{{ item.datePublished|slice:":10" }}
{{ item.description }}
{{ item.provider.name }}
The site is live and can be seen at https://covid19ph-unofficial.icvn.tech/.
