Django: After updating a template, the changes are not reflected upon refreshing the page in the bro-CodePudding

I am testing a class based view in my Django application. I am currently in development, so I want to see changes in the browser as soon as I make any change in a template.

The urls.py of the main app is below:

urlpatterns = [
    path('myapp/', include('myapp.urls')),
]

urls.py of myapp:

from django.urls import path, include
from . import views

urlpatterns = [
    path('all/', views.AllView.as_view(), name="myapp-all"),
]

The views.py file in myapp looks like below:

from django.views import View
from django.template import loader
from django.http import HttpResponse

# Create your views here.
class AllView(View):
    template = loader.get_template('myapp/all.html')
    
    def get(self, request, *args, **kwargs):
        return HttpResponse(self.template.render(request=request))

The all.html template looks like below:

{% extends 'base.html' %}
{% block title %} Example Table {% endblock %}

{% block content %}
<div >
    <div >
        <table >
            <thead>
              <tr>
                <th scope="col">#</th>
                <th scope="col">First</th>
                <th scope="col">Last</th>
                <th scope="col">Handle</th>
              </tr>
            </thead>
            <tbody>
              <tr>
                <th scope="row">1</th>
                <td>Mark</td>
                <td>Otto</td>
                <td>@mdo</td>
              </tr>
              <tr>
                <th scope="row">2</th>
                <td>Jacob</td>
                <td>Thornton</td>
                <td>@fat</td>
              </tr>
              <tr>
                <th scope="row">3</th>
                <td colspan="2">Larry the Bird</td>
                <td>@twitter</td>
              </tr>
            </tbody>
          </table>
    </div>
</div>
{% endblock %}

The above template is stored in the below directory: base_directory -> myapp -> templates -> myapp -> all.html

The settings.py file has the following configuration:

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': ['core/templates'],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

DEBUG = True

As you can see the APP_DIRS is set to true. If I change anything in the template and refresh the page (created by that url) in the browser, the changes are not reflected, and I need to restart my server to see the changes. What am I doing wrong here?

CodePudding user response：

I guess your template is only loaded during initialization:

loader.get_template('myapp/all.html')

You can try the following, which is also suggested by the django documentation:

class AllView(View):
   template_name = 'myapp/all.html'

    def get(self, request, *args, **kwargs):
        return render(request, self.template_name)

Of if you only need to render a template, you can use the TemplateView:

from django.views.generic import TemplateView

class AboutView(TemplateView):
    template_name = 'myapp/all.html'

CodePudding user response：

Template directories must be associated with BASE_DIR to work perfectly.

Try this:

'DIRS': [BASE_DIR , 'templates'],

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [BASE_DIR , 'templates'],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]
