[PYTHON] Get news from three major mobile companies using Django and the News API
Introduction
I am new to programming, so I hope you will read this article with warm eyes.
environment
Windows10 Python 3.7.6 newsapi-python 0.2.6 Django 3.0.6 DateTime 4.3
The name of the directory at the time of creation is as follows.
sample_news
├─news
├─sample_news
├─static
└─manage.py
Introducing News API
Go to News API Site and enter your email address to get the API key, and make a note of the API key. Then use pip to install the NewsAPI library.
pip install newsapi-python
Add the following code to setting.py in sample_news to use the News API. For api_key, enter the key you wrote down.
setting.py
from newsapi import NewsApiClient
newsapi=NewsApiClient(api_key='xxxxxxxxxxxxxxxxxxxxxx')
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'news.apps.NewsConfig',
'newsapi',
]
You can now use the News API.
Creating a news app
Routing settings
Add the following code to urls.py in sample_news to configure the routing.
sample_news/urls.py
from django.contrib import admin
from django.urls import path,include
urlpatterns = [
path('admin/', admin.site.urls),
path('',include('news.urls')),
]
Next, I created urls.py in news and entered the following code.
news/urls.py
from django.urls import path
from.import views
app_name = 'news'
urlpatterns = [
path('', views.IndexView.as_view(), name="index"),
path('docomo/',views.DocomoView.as_view(),name="docomo"),
path('au/',views.AuView.as_view(),name="au"),
path('softbank/',views.SoftbankView.as_view(),name="softbank")
]
Get news with News API
There are two ways to get the top news in the News API and to get the news for a certain period in the past.
When I got the top news, nothing was displayed if there was no news, so I adopted the method of getting the news for a certain period of time. The News API allows you to get news up to 30 days in advance if you don't charge.
This time, I specified the keyword, period, display order, and number of news. There are also title keywords, sources, domains, languages (Japanese is not allowed), etc.
news/views.py
from django.views import generic
from newsapi import NewsApiClient
from datetime import datetime, date, timedelta
class IndexView(generic.TemplateView):
template_name = "index.html"
class DocomoView(generic.TemplateView):
template_name = "docomo.html"
def get_context_data(self, **kwargs):
context=super().get_context_data(**kwargs)
today = date.today()
monthago = today-timedelta(days=30)
newsapi = NewsApiClient(api_key='e56b4ed3346745e3800bc521d085e04b')
context['all_article']=newsapi.get_everything(q='DoCoMo',
from_param=monthago,
to=today,
sort_by='publishedAt',
page_size=40)
return context
class AuView(generic.TemplateView):
template_name = "au.html"
def get_context_data(self, **kwargs):
context=super().get_context_data(**kwargs)
today = date.today()
monthago = today-timedelta(days=30)
newsapi = NewsApiClient(api_key='e56b4ed3346745e3800bc521d085e04b')
context['all_article']=newsapi.get_everything(q='KDDI',
from_param=monthago,
to=today,
sort_by='publishedAt',
page_size=40)
return context
class SoftbankView(generic.TemplateView):
template_name = "softbank.html"
def get_context_data(self, **kwargs):
context=super().get_context_data(**kwargs)
today = date.today()
monthago = today-timedelta(days=30)
newsapi = NewsApiClient(api_key='e56b4ed3346745e3800bc521d085e04b')
context['all_article']=newsapi.get_everything(q='Softbank',
from_param=monthago,
to=today,
sort_by='publishedAt',
page_size=40)
return context
Now that the program to get the news is complete, all you have to do is coat it.
Display the acquired news
This time, 4 of the top page (index.html), the page that displays docomo news (docomo.html), the page that displays au news (au.html), and the page that displays Softbank news (softbank.html). I created one page and five html files of the part common to each page (base.html).
templates
├─au.html
├─base.html
├─docomo.html
├─index.html
└─softbank.html
The pages that display doCoMo news are as follows.
This time, the title, url, and news image are acquired and displayed.
docomo.html
{% extends 'base.html' %}
{% block title %}Sample_News | SOFTBANK{% endblock %}
{% block contents %}
<div class="grid">
{% for context in all_article.articles %}
<div class="news">
<div class="news-wrapper">
<img class="news-img" src="{{ context.urlToImage }}" alt="">
<a class="news-title" href="{{ context.url }}">{{ context.title }}</a>
</div>
</div>
{% endfor %}
</div>
{% endblock %}
Like this, I also write au and Softbank html files.
Finally, coding with CSS is completed.

DoCoMo news page
Summary
This is the first web app I made after studying django, so I made it using a lot of reference books. After studying, I felt that I could deepen my understanding by making my own web application for revenge.
I did the search words for docomo for docomo, au for au, and Softbank for softbank, but docomo output only docomo news, but au outputs overseas news and Softbank outputs baseball news. Since it was done, I would like to improve it.
Also, since this is my first time writing an article, I would appreciate it if you could let me know if there is something you cannot reach.
