Django：20个html文件：需要20个TemplateViews和20个URL模式吗？

Question

我有20个Django简单的“ foo.html”模板文件。

我在url_patterns中需要20个TemplateViews和20个条目吗？还是有一个更简单的解决方案？

Answer 1

使用Django 2.1和基于类的视图，您的urls.py应该像这样：

from django.urls import path

from your_app import views

app_name = 'your_app'

urlpatterns = [
    path('foo/<str:name>/', views.Foo.as_view(), name='foo'),
]

您的views.py如下：

from django.views import generic


class Foo(generic.TemplateView):

    def get_template_names(self)
        name = self.kwargs.get('name')
        # compute the template you want, for the example, I just take the name
        template_name = f'your_app/{name}.html'
        return [template_name]

仅此而已；）

Answer 2

您可以使用path('pages/<str:page>, views.pages)

这样的路径

然后在视图中执行类似的操作：

from django.template.loader import get_template
from django.template import TemplateDoesNotExist

def pages(request, page):
    template_name = f'your-app/{page}.html'
    try:
        get_template(template_name)
        return render(request, template_name)
    except TemplateDoesNotExist:
        # returns 404

Answer 3

使用django 2.x的简单解决方案。

由于您听起来对django较新，因此此解决方案应该容易得多。没有理由在简单的事情上使用f字符串和try / except块。而且我知道当我开始时，基于类的视图没有任何意义，因为没有控制流。

urls.py

from django.urls import path
from . import views

app_name = 'article_app'

urlpatterns = [
    path('', views.article_list, name='article_list'),
    path('new/', views.article_new, name='article_new'),
    path('<int:art_pk>/', views.article_detail, name='article_detail'),
    path('<int:art_pk>/update/', views.article_update, name='article_update'),
    path('<int:art_pk>/delete/', views.article_delete, name='article_delete'),
    # and so on....
]

views.py

from django.shortcuts import render
from .models import Article

def article_detail(request, art_pk):
    article = Article.objects.get(pk=art_pk)
    return render(request, 'articles_app/article_detail.html', {'article': article})

article_detail.html的模板

{% block maincontent %}

   <div class="article">
     <h2><u>{{ article.title }}</u></h2>
     <h3>By: {{ article.author }} --- Posted / Updated on: {{ article.date }}</h3>
     <p>{{ article.body }}</p>
     <p><a href="{% url 'article_app:article_update' article.pk %}">Update</a> | <a href="{% url 'article_app:article_delete' article.pk %}">Delete</a></p>
     <p><a href="{% url 'article_app:article_list' %}">Back to all articles</a></p>
   </div>

{% endblock maincontent %}

如果您遇到更复杂的事情：

让我们说这是需要一些if / else语句来描述Food模型的事情。示例：

models.py

class Food(models.Model):
    FLAVOR_CHOICES = (
        ('tasty', 'Very yummy'),
        ('disgusting', 'Nasty AF bro!'),
        ('super_sweet', 'For little kids'),
        ('bitter', 'Sure to grow hair on you balls!'),
    )
    food_choice = models.CharField(max_length=30, choices=FLAVOR_CHOICES, default='super_sweet')
    # and any other attribute for a Food

urls.py

app_name = 'food_app'

urlpatterns = [
    # ....
    path('<int:food_id>/', views.show_food, name='show_food'),
]

views.py

def show_food(request, food_id):
    food = Food.objects.get(id=food_id)
    if food.food_choice == 'tasty':
        return render(request, 'food_app/food_stats.html', {'tasty': 'Everyone likes tasty things'})
    elif food.food_choice == 'bitter':
        return render(request, 'food_app/food_stats.html', {'bitter': 'Girls do not want to have balls. Sure way to end the gene pool.'})
    # .... and so on with other choices
    else:
        return render(request, 'food_app/food_stats.html')

然后您的food_stats.html模板看起来像这样

请注意，应该使用而不是为'bitter.html'，'tasty.html'，'super_sweet.html'等创建单独的页面。

{% block maincontent %}

  <h1>Your choice of food:</h1>

  {% if tasty %}
      <p>{{ tasty.food_choice }}</p>  {# this attribute would show the 2nd value for 'tasty' in the tuple of FLAVOR_CHOICES - 'Very yummy' #}
      <p>{{ tasty }}</p>   {# The value that shows here is the key I set in the view #}

  {% elif disgusting %}
      <p>{{ disgusting.food_choice }}</p>
      <p>{{ disgusting }}</p>

  {% elif super_sweet %}
      <p>{{ super_sweet.food_choice }}</p>
      <p>{{ super_sweet }}</p>

  {% elif bitter %}
      <p>{{ bitter.food_choice }}</p>
      <p>{{ bitter }}</p>

  {% else %}
      <p>No foods bro. You're lame.</p>

  {% endif %}

{% endblock maincontent %}

从django.conf.urls

导入URL 从.import视图中获取

urlpatterns = [     ＃url（r'^ / $'，views.function_name，name =“ Page”）

url(r'^$', views.home, name="Home Page"),

]

使用此模式匹配来显示您的.html页面
