Question

我决定将现有的Angular 2应用程序集成到我的Django REST项目中。

使用我的前端的静态文件夹创建Django应用程序：

urls.py：

from django.conf.urls import url
from frontend import views
from django.conf import settings
from django.conf.urls.static import static


urlpatterns = [
    url(r'^$', views.index,  name='index'),
] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)

views.py：

from django.shortcuts import render

def index(request):
    """
    Renders the Angular2 SPA
    """
    return render(request, template_name='index.html')

将我的Angular 2应用移动到前端静态文件夹

在我的设置中添加静态设置：

STATIC_URL = '/static/'
STATICFILES_DIRS = [
    os.path.join(BASE_DIR, 'frontend', 'static'),
]

STATIC_ROOT = os.path.join(BASE_DIR, 'static')

在index.html中进行更改：

<html>
  <head>
    <base href="/">
    <title>PhotoHub</title>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    {% load staticfiles %}


    <link rel="stylesheet" href="{% static "node_modules/bootstrap/dist/css/bootstrap.min.css" %}">
    <link href="{% static "bower_components/font-awesome/css/font-awesome.min.css" %}" rel="stylesheet" />
    <link href="{% static "bower_components/alertify.js/themes/alertify.core.css" %}" rel="stylesheet" />
    <link href="{% static "bower_components/alertify.js/themes/alertify.bootstrap.css" %}" rel="stylesheet" />
    <link rel="stylesheet" href="{% static "styles.css" %}">

    <script src="{% static "bower_components/jquery/dist/jquery.min.js" %}"></script>
    <script src="{% static "node_modules/bootstrap/dist/js/bootstrap.min.js" %}"></script>
    <script src="{% static "bower_components/alertify.js/lib/alertify.min.js" %}"></script>
    <!-- 1. Load libraries -->
     <!-- Polyfill(s) for older browsers -->
    <script src="{% static "node_modules/core-js/client/shim.min.js" %}"></script>
    <script src="{% static "node_modules/zone.js/dist/zone.js" %}"></script>
    <script src="{% static "node_modules/reflect-metadata/Reflect.js" %}"></script>
    <script src="{% static "node_modules/systemjs/dist/system.src.js" %}"></script>
    <!-- 2. Configure SystemJS -->
    <script src="{% static "systemjs.config.js" %}"></script>
    <script>
      System.import('app').catch(function(err){ console.error(err); });
    </script>
  </head>
  <!-- 3. Display the application -->
  <body>
    <photohub></photohub>
  </body>
</html>

在systemjs.config.js中进行更改：

(function (global) {
  System.config({
    //static
    defaultJSExtensions: true,
    paths: {
      // paths serve as alias
      'npm:': 'static/node_modules/'
    },
    // map tells the System loader where to look for things
    map: {
      app: 'static/dist',
      // angular bundles
      '@angular/core': 'npm:@angular/core/bundles/core.umd.js',
      '@angular/common': 'npm:@angular/common/bundles/common.umd.js',
      '@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js',
      '@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js',
      '@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js',
      '@angular/http': 'npm:@angular/http/bundles/http.umd.js',
      '@angular/router': 'npm:@angular/router/bundles/router.umd.js',
      '@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js',
      // other libraries
      'rxjs':                      'npm:rxjs',
      'angular-in-memory-web-api': 'npm:angular-in-memory-web-api',
    },
    // packages tells the System loader how to load when no filename and/or no extension
    packages: {
      app: {
        main: './main.js',
        defaultExtension: 'js'
      },
      rxjs: {
        defaultExtension: 'js'
      },
      'angular-in-memory-web-api': {
        main: './index.js',
        defaultExtension: 'js'
      }
    }
  });
})(this);

TypeScript文件在/dist中编译，模板保留在/app中。当我使用两台不同的服务器时，templateUrl的路径如下所示：

templateUrl: './app/app.component.html'

现在我试图以这种方式声明templateUrl，但它不起作用：

templateUrl: '{{ STATIC_URL }}' + '/app/app.component.html'

现在如何处理模板网址？

响应：

“GET /app/components/login/login.component.html HTTP / 1.1”404 2601
找不到：/app/app.component.html

JavaScript文件加载良好：

“GET /app/components/login/login.component.html HTTP / 1.1”404 2601
找不到：/app/components/register/register.component.html

Answer 1

这解决了问题：

Query query = database.child(user.getUid()).orderByValue();
query.addChildEventListener(...

Answer 2

我不确定您有什么错误，但您可能应该使用static标记在模板中创建静态资产的网址：

{% load static %}

templateUrl: "{% static '/app/app.component.html' %}"
