I'm new to django and currently trying to find an effective way to load css files in the django templating language depending on the current page. The url pattern is :
path('invoices/', views.list, name='invoice_list'),
path('invoices/new/', views.create, name='create_invoice'),
path('invoices/<int:pk>/', views.edit, name='edit_invoice'),
path('invoices/<int:pk>/lines/new', views.create_line, name='create_line'),
path('invoices/<int:pk>/lines/<int:fk>', views.update_line, name='update_line'),
In the base.html, this is what i'm doing:
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link rel="stylesheet" href="{% static 'invoice/css/common.css' %}">
{% if request.path == '/invoices/'%}
<link rel="stylesheet" href="{% static 'invoice/css/invoice_list.css' %}">
{% endif %}
{% if '/invoices/' in request.path and request.path != '/invoices/' and '/line/' not in request.path %}
<link rel="stylesheet" href="{% static 'invoice/css/edit_invoice.css' %}">
{% endif %}
<title>My invoices </title>
</head>
the {% if '/invoices/' in request.path and request.path != '/invoices/' and '/line/' not in request.path %} is not great at all and would like to know if there's a nicer way to do it regexp style maybe?
Thanks in advance.
You should not put such logic in the template. Instead you should use the block and extends template tag for this purpose. See Template inheritance [Django docs]:
In base.html:
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link rel="stylesheet" href="{% static 'invoice/css/common.css' %}">
{% block extra_css %}
{% endblock extra_css %}
<title>My invoices </title>
</head>
Now in the template which is rendered when if request.path == '/invoices/' is true, you will fill this block as:
{% extends "base.html" %}
...
{% block extra_css %}
<link rel="stylesheet" href="{% static 'invoice/css/invoice_list.css' %}">
{% endblock extra_css %}
Similarly In the template which is rendered when if '/invoices/' in request.path and request.path != '/invoices/' and '/line/' not in request.path is true you you will fill the block as:
{% extends "base.html" %}
...
{% block extra_css %}
<link rel="stylesheet" href="{% static 'invoice/css/edit_invoice.css' %}">
{% endblock extra_css %}

i want to show up my Flash Messages in my template. It works, but i cant tell the template where to show or how to show it. It appears all the time in the same place and the same style.
This is my view:
def exportBefunde(request):
(...)
messages.info(request, "Befund exportiert")
return redirect("reporting")
This is my main.html template
{% load static %}

{% if messages %}
{% for message in messages %}

I want to show my template underneath my content. But i appears above it. Even if i remove this peace of code:
{% if messages %}
{% for message in messages %}
<p id="messages">{{message}}</p>
{% endfor %}
{% endif %}
the message shows up above the code. The styling is always the same. Django ignores my Code in my template. Do anyone has a solution for this issue?
I'm working with Django1.8.
I can't overtwrite the version_tag block in my base.html file. It always appears the default content.
This is a simplified version of my base.html:
{% load staticfiles %}
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link href="{% static 'myApp/img/favicon.png' %}" rel="icon" type="image/png" />
<title>{% block title %}{% endblock %}</title>
<link rel="stylesheet" type="text/css" href="{% static 'myApp/lib/css/bootstrap.min.css' %}" />
<link rel="stylesheet" type="text/css" href="{% static 'myApp/lib/css/themes/bootstrap.min.css' %}" />
<script type="text/javascript" src="{% static 'myApp/lib/js/jquery.min.js' %}"></script>
</script>
</head>
<body>
<div id="main">
{% block menu %}
{% include "myApp/menu.html" %}
{% endblock menu %}
<div id="container" class="container-fluid">
{% block content %}
{% endblock content %}
</div>
</div>
{% block version_tag %}Default Version{% endblock version_tag %}
</body>
</html>
On the same folder I have the version_tag.html file:
{% extends 'myApp/base.html' %}
{% block version_tag %}
V. 1.2.3
{% endblock %}
What am I missing or doing wrong? Why does it always appear Default Version instead of V. 1.2.3?
There are only two possible causes I can think of:
Your view is still trying to render base.html instead of your inherited html template.
Simply change the view to call the correct one (version_tag.html)
The template you're really trying to display is still inheriting from base.html instead of version_tag.html
I am getting an error message while adding a template to base.html with include tag. All other templates are rendered properly with no issues but this got issues while I try to add it. The error is:

Your template extends from base.html which then needs to include the template, which then needs to extend from base.html which then needs to include the template, which then needs to extend from base.html then needs to include the template, which then needs to extend from base.html...
Remove {% extends 'base.html' %} from the template you're trying to include as well as any reference to blocks.

When i visit "http://127.0.0.1:8000/product/product_list/" following error pops up
My directory structure, My base.html is in root directory(templates) and product_list.html is in products folder
I think there could be problem with {% extends 'base.html' %}, But not sure how to sole the problem.......Any help is much appreciated
Here's my first urls...which further redirects to my app url.py
from django.conf.urls import url, include
from django.contrib import admin
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^product/', include('products.urls')),
url(r'^accounts/', include('registration.backends.default.urls')),
]
You need to specify a name to the view url that identify when you want to used in the template
from django.conf.urls import url
import myapplication.views
app_urlpatterns = [
url(r'^article/(\d+)/$',views.article_detail,name='article-view-url'),
]
And this is how I use the url name in my html template
{% for article in articles.object_list %}
<article>
<h3>
{{ article.name }}
</h3>
<p>
{{ article.desc }}
</p>
</article>
{% endfor %}
I've 2 templates. Here is the listing:
1)base.html
<!DOCTYPE html>
<html>
<head>
{% load staticfiles %}
<link type="text/css" rel="stylesheet" href={% static 'resume/stylesheet.css'%}/>
<title>{% block title %}{% endblock %}</title>
</head>
<body>
<div id=header> some info </div>
{% block content %}{% endblock %}
</body>
</html>
2)person.html
{% extends "base.html" %}
{% block title %}Personal info{% endblock %}
{% block content %}
<div>{{person.first_name}}</div>
{% endblock %}
I use template "person.html" in my view
def person_view(request):
person = get_object_or_404(Person, pk=1)
return render(request, "resume/person.html", {'person': person})
urls.py:
url(r'^$', views.person_view, name='person'),
The problem is, when I run the server, and trying to open page with this url, there is only text and information from "person.html" template(meaning of "person.first_name"). Information from "base.html" and css styles don't used.
You forgot double quotes:
<link type="text/css" rel="stylesheet" href={% static 'resume/stylesheet.css'%}/>
should be:
<link type="text/css" rel="stylesheet" href="{% static 'resume/stylesheet.css'%}"/>
Edit
here as well:
<div id=header>
should be:
<div id="header">
