Using APIs within Django and how to display the data

问题

I am trying to test how to display API information within a view on my Django project. I know you may have to add some installed APIs into the settings INSTALLED APPS block.

This api is a simple geo one.

I am new to Django and new to using APIs within it. I have managed to get my app the way I need it using Youtube videos. But now I am on my own. I have many different view classes to display differents of my app.

The view below is the view Id like to place the data on.

is this how I would potentially do it? Then call {{ base }} within the HTHL to display it?

class PostDetailView(DetailView):
    model = Post
    template_name = 'clients/post_detail.html'

    def api_test(request):
        #  This is where the APIs are going to go.
        requests.get('https://api.coindesk.com/v1/bpi/currentprice.json')
        data = response.json()
        return render(request, 'clients/post_detail.html', {
            'base': data['disclaimer']
        })

I am currently getting no errors within my app, but the country element isnt displaying.

I have tested the following in just a simple python file

import requests
import json

response = requests.get('https://api.coindesk.com/v1/bpi/currentprice.json')
data = response.json()

print(data['disclaimer'])

which gets the desired result. So I guess now my issue is...how do i get this into the HTML? So i can display the results from the API

回答1:

You can write like this:

class PostDetailView(DetailView):
    model = Post
    template_name = 'clients/post_detail.html'

    def call_geo_api(self):
        #  This is where the APIs are going to go.
        response = requests.get('https://api.coindesk.com/v1/bpi/currentprice.json')
        data = response.json()
        return data['disclaimer']

    def get_context_data(self, *args, **kwargs):
        context = super(PostDetailView, self).get_context_data(*args, **kwargs)
        context['base'] = self.call_geo_api()
        return context

Here, I have overridden get_context_data() method, which is responsible for sending context data from view to template.

Here I have changed your api method, so that it will return data['disclaimer'] from the API, and inside get_context_data method, I have injected it inside context. That should do the trick, so that you will be able to see data in template with {{ base }}.
