Django-项目中的第二个应用程序，找不到页面

Question

我无法弄清楚在我的项目名为 'weather' 的第二个应用程序中我做错了什么。第一部分 'home' 工作正常。我这样做是为了让一个空的 url '' 和一个带有 '/home/' 的 url 都映射到主页。即使是我在主页导航栏中创建的 link 也能正常工作，但天气 link 就不行了。我最终收到 'Page not found 404' 错误。

这里是概述： Project structure

我在设置安装的应用程序中包含了应用程序 'weather'。

主项目文件夹中的urls.py文件：

from django.contrib import admin
from django.urls import path, include
from weather import views


urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('blog.urls')),
    path('', include('weather.urls')),
    ]

我的天气应用的 urls.py 文件：

from weather import views
from django.urls import path

urlpatterns = [
    path('', views.GetWeather.as_view(), name='weather'),

]

天气应用 views.py：

from django.views import generic
import requests
from django.shortcuts import render
from .models import City
from .forms import CityForm


class GetWeather(generic.ListView):

    queryset = City.objects.order_by('-requested')

    template_name = 'weather.html'

def index(request):
    url = 'http://api.openweathermap.org/data/2.5/weather?q={}&units=imperial&appid=c5a079de62bccff63d64ac8989f87e37'

    form = CityForm()

    cities = City.objects.all()

    weather_data = []

    for city in cities:

        r = requests.get(url.format(city)).json()

        city_weather = {
            'city' : city.name,
            'temperature' : r['main']['temp'],
            'description' : r['weather'][0]['description'],
            'icon' : r['weather'][0]['icon'],
        }

        weather_data.append(city_weather)

    context = {'weather_data' : weather_data, 'form' : form}
    return render(request, 'templates/weather.html', context)

天气应用 models.py：

from django.db import models
from django.contrib.auth.models import User

class City(models.Model):
    name = models.CharField(max_length=30)

    requested = models.DateTimeField(auto_now_add = True)

    class Meta:
        ordering = ['-requested']

    def __str__(self):
        return self.name

    class Meta:
        verbose_name_plural = 'cities'

weather.html 模板：

<!DOCTYPE html>
{% extends "base.html" %}
{% block content %}

<html>
<style>
    body {
        font-family: "Roboto", sans-serif;
        font-size: 18px;
        background-color: rgba(0, 0, 0, .75);
        }

    .head_text{
        color: white;
        }
    .card{
        box-shadow: 0 16px 48px #E3E7EB;
        }
</style>

        <div class="container">
            <div class="row">
                <div class="col-md-8 mt-3 left">
                    {% for city_weather in weather_data %}
                    <div class="card mb-4">
                        <div class="card-body">
                            <h2 class="media-left">
                                <figure class="image is-50x50">
                                    <img src="http://openweathermap.org/img/w/{{ city_weather.icon }}.png" alt="Image">
                                </figure>
                            </h2>
                            <div class="media-content">
                                <div class="content">
                                    <p>
                                        <span class="title">{{ city_weather.city }}</span>
                                        <br>
                                        <span class="subtitle">{{ city_weather.temperature }}° F</span>
                                        <br> {{ city_weather.description }}
                                    </p>
                                </div>
                            </div>
                        </div>
                    </div>
                    {% endfor %}
                </div>
            </div>
        </div>
</html>
{% endblock content %}

这是blog.urls:

from . import views
from django.urls import path

urlpatterns = [
    path('', views.PostList.as_view(), name='home'),
    path('<slug:slug>/', views.PostDetail.as_view(), name='post_detail'),
]

我非常感谢任何花时间阅读本文并帮助我的人。

您必须首先更改 blogs/urls.py 或 weather/urls.py 匹配项 URL。这取决于您想在基地上看到什么 URL.

# weather/urls.py

from weather import views
from django.urls import path

urlpatterns = [
    path('weather/', views.GetWeather.as_view(), name='weather'),

]

# blog/urls.py

from . import views
from django.urls import path

urlpatterns = [
    path('', views.PostList.as_view(), name='home'),
    path('blog/<slug:slug>/', views.PostDetail.as_view(), name='post_detail'),
]

这应该可以解决，假设您希望在第一页显示天气详细信息。
