在Django中使用API​​以及如何显示数据 [英] Using APIs within Django and how to display the data

问题描述

我正在尝试测试如何在Django项目的视图中显示API信息。我知道您可能必须将一些已安装的API添加到INSTALLED APPS设置块中。

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.

此api是一个简单的地理区域应用程序。

This api is a simple geo one.

我是Django的新手，也是第一次使用api。我已经通过YouTube视频成功地按照自己的方式获取了我的应用。但是现在我自己一个人。我有许多不同的视图类来显示我的应用程序的不同之处。

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.

下面的视图是要放置数据的视图。

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

这是我可能会这样做的方式吗？然后在HTHL中调用{{base}}来显示它？

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']
        })

我目前在我的应用程序中没有收到任何错误，但是没有显示country元素。

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

我已经在一个简单的python文件中测试了以下内容

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'])

这将获得所需的结果。所以我想现在我的问题是...如何将其导入HTML？这样我就可以显示API的结果

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

推荐答案

您可以这样写：

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

这里，我有覆盖 get_context_data（） 方法，该方法负责将上下文数据从视图发送到模板。

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

在这里，我更改了您的api方法，以便它将从API返回 data ['disclaimer'] ，并在 get_context_data 方法内部，已将其注入上下文中。这样就可以解决问题，以便您可以使用 {{base}} 看到模板中的数据。

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 }}.
