Представлено с ошибкой TemplateDoesNotExist

Question

Я сделал два файла

market.py crypto.html

Код в маркере py извлекает данные из двух адресов API и должен показывать их в crypto.html, когда язапустите сервер и попробуйте открыть crypto.html, который мне представлен с TemplateDoesNotExist в / crypto /

, как объяснили другие посты на софе. Я пытался повозиться с INSTALLED_APPS = [однако я не могу заставить страницу функционировать.

market.py

import requests, time
from django.shortcuts import render


class CryptoData:
   def __init__(self):
    self.usd_url = "https://api.coingecko.com/api/v3/coins/markets?" \
               "vs_currency=usd&order=market_cap_desc&per_page=250&page=1" 
\
               "&sparkline=false&price_change_percentage=24h"
self.gbp_url = "https://api.coingecko.com/api/v3/coins/markets?" \
               "vs_currency=gbp&order=market_cap_desc&per_page=250&page=1" 
\
               "&sparkline=false&price_change_percentage=24h"

self.previous_request = None
self.results1 = None
self.results2 = None

def get_crypto_data_dict(self, seconds_to_wait=60):
crypto_dict = dict()
if not self.previous_request or self.previous_request + seconds_to_wait < 
time.time():
    print("requested", self.previous_request, time.time())
    self.previous_request = time.time()
    crypto_dict = dict()
    requests1 = requests.get(self.usd_url)
    self.results1 = requests1.json()

    requests2 = requests.get(self.gbp_url)
    self.results2 = requests2.json()

for i in range(0, 250):
    crypto_dict[self.results1[i]['id']] = {
        'coin_name': self.results1[i]['name'],
        'changes': self.results1[i]['price_change_percentage_24h'],
        'usd': self.results1[i]['current_price'],
        'gbp': self.results2[i]['current_price']
    }

return crypto_dict


crypto_data = CryptoData()


def crypt_view(request):
context = {
    'crypto_data': crypto_data.get_crypto_data_dict()
}

return render(request, 'crypto.html', context=context)

crypto.html

{% extends "blog/base.html" %}
{% block content %}
    <ul>
         {% for crypto_datum, crypto_value in crypto_data.items %}
            <li>{{ crypto_datum }}
                <ul>

                    {% for info, value in crypto_value.items %}
                        <li>{{ info }}: {{ value }}</li>
                    {% endfor %}


                </ul>

views.py

from django.shortcuts import render
from django.http import HttpResponse
from django.views.generic import ListView, DetailView, CreateView

from coinGecko import market
from .models import Post


def home(request):
context = {
    'posts': Post.objects.all()
}
return render(request, 'blog/home.html', context)


class PostListView(ListView):
model = Post
template_name = 'blog/home.html'
context_object_name = 'posts'
ordering = ['-date_posted']


class PostDetailView(DetailView):
model = Post


class PostCreateView(CreateView):
model = Post
fields = ['title', 'content']

def form_valid(self, form):
    form.instance.author = self.request.user
    return super().form_valid(form)


def about(request):
return render(request, 'blog/about.html', {'title': 'About'})

def crypt_view(request):
cryto_data = market.CryptoData

context = {
    'crypto_data': market.crypto_data.get_crypto_data_dict()
}

return render(request, 'coinGecko/crypto.html', context=context)

Я проверил market.py ион отображал правильные данные, когда я установил их для печати каждой строки.Мне удалось просмотреть его в выводе cmd.

Я знаю, что код работает, но я думаю, что сейчас проблема в том, что market.py выводит данные в crypto.html

Текущий вывод при шифровании.html открывается:
