I am using this django-plugin here: https://github.com/chronossc/django-breadcrumbs
But I can't seem to be able to check in the templates if there is actually an array of breadcrumbs or not… I have tried:
{%if request.breadcrumbs%} {% if request.breadcrumbs|length > 0%}
and so on… but nothing truly tells me if there are some or not.
I want this bar to appear if I passed in breadcrumbs, and not appear in the case that I didn't pass some breadcrumbs in my view:
{% if request.breadcrumbs|length > 0 %}
<div class="navbar navbar-fixed-top" style="top:38px;z-index:1029;" id="breadcrumb-sticky-header">
<div class="container">
<div class="container-fluid">
<div class="row-fluid">
<ul id="breadcrumb-sticky-header-inner" class="breadcrumb">
{% for breadcrumb in request.breadcrumbs %}
{% if not forloop.last %}
<li>{{ breadcrumb.name }} <span class="divider">/</span></li>
{% else %}
<li class="active">{{ breadcrumb.name }}</li>
{% endif %}
{% endfor %}
</ul>
</div>
</div>
</div>
</div>
{% endif %}
Here is the code in my view:
#login_required
def view(request, t_id):
try:
tshoot = Troubleshoot.objects.select_related('category', 'equipment', 'equipment__model').get(pk=t_id)
request.breadcrumbs([
(("%s: %s" % (tshoot.equipment.model.name, tshoot.equipment.serial)),
'/equipment/view/%s/' % (tshoot.equipment.id)),
(("%s" % (tshoot.category.name)),
'/troubleshoot/categories/view/%s/' % (tshoot.category.id)),
((tshoot.title), '')
])
Based on the code in the django-breadcrumbs project (line 191 in breadcrumbs.py: https://github.com/chronossc/django-breadcrumbs/blob/master/breadcrumbs/breadcrumbs.py#L191), It looks like they've implemented a .all() method.
You should be able to use the |length template filter on the results of the .all() method to get the result you want, like so:
{% if request.breadcrumbs and request.breadcrumbs.all|length > 0 %}
I have not tested this; this is what my quick code inspection revealed.
Not sure what request.breadcrumbs|length > 0 does, but I would use the sample template:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN""
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8">
<title>Breadcrumbs test page | {% for b in request.breadcrumbs %}{{ b.name }}{% if not forloop.last %} > {% endif %}{% endfor %}</title>
</head>
<body>
{{ request.breadcrumbs }}
<p>Breadcrumb: {% for b in request.breadcrumbs %}{{ b.name }}{% if not forloop.last %} / {% endif %}{% endfor %}</p>
<p>Links: <a href='/'>Home</a> | <a href='/someview/'>Breadcrumb in view</a> | <a href='/flat01/'>Flatpages</a>
<p>Content: <br>
{% if text %}{{ text }}{% endif %}
{% if flatpage %}{{ flatpage.content }}{% endif %}
</body>
</html>
and view until you are comfortable with how it works:
# Create your views here.
from django.shortcuts import render_to_response
from django.template.context import RequestContext
def home(request):
print request.breadcrumbs
return render_to_response('home.html',
{'text': 'Hello, this is home!'},
context_instance=RequestContext(request))
def someview(request):
request.breadcrumbs('just a view to show some url', request.path)
return render_to_response('home.html',
{'text': 'Hello, this is some second view'},
context_instance=RequestContext(request))

What is the easiest / fastest way to override Django admin form to display grid of elements instead of list? My model includes a field for a 100x100px pic, and it would be easier to see them as a grid of pictures, not a list.
This is not terribly difficult, but it requires you to copy several large chunks of code from the Django library and incorporate them into your own application. Here's the overview:
You'll need to copy and then modify several template tags from django.contrib.admin.templatetags.admin_list:
django.contrib.admin.templatetags.admin_list.items_for_result
django.contrib.admin.templatetags.admin_list.result_list
django.contrib.admin.templatetags.admin_list.results
django.contrib.admin.templatetags.admin_list.result_list_tag
You'll need to copy and then modify a couple of templates:
django/contrib/admin/templates/admin/change_list.html
django/contrib/admin/templates/admin/change_list_results.html
For purposes of illustrating the solution, I have created an app called spam and a model called SpamPhoto, along with a model admin that is customized to display the image tag. I am using Bootstrap 4 for the grid. There are still some issues you might need to track down and figure out, like getting rid of the checkbox that shows up for each item. But this code should get about 90% of the way there.
Here's an overview of the files that I created/modified, and which you'll find below:
spam/models.py: contains the SpamPhoto model
spam/admin.py: contains the SpamPhotoAdmin
spam/templatetags/spamphoto_admin_list.py: contains the template tag / functions that will render the customized change list
spam/templates/admin/spam/spamphoto/change_list.html: this is the main changelist template, and only has a few small changes: it loads our custom template tags, it includes Bootstrap CSS, and it calls a customized template tag (defined below)
spam/templates/admin/spam/spamphoto/change_list_results.html: heavy modifications here, getting rid of the table elements and replacing with divs.
So again, this is a LOT of code, and most of it is lifted directly without very many changes. Here we go:
# spam/models.py
from django.db import models
class SpamPhoto(models.Model):
name = models.CharField(max_length=100)
image = models.ImageField()
# spam/admin.py
from django.contrib import admin
from django.utils.html import mark_safe
class SpamPhotoAdmin(admin.ModelAdmin):
list_display = ('name', 'image_tag')
list_display_links = ('name', 'image_tag')

I am following the book 'Django 2 By Example' and at this point I believe I have directly copy and pasted the code from here (https://github.com/PacktPublishing/Django-2-by-Example/tree/master/Chapter04) to try and fix this error, but I am still getting. I should note that I am using Django 3.2.6 and am not sure if this is causing it. Thanks for any help with this.

I have read their documentation but I haven't found anything related to some custom template integration. Could anyone please lead me in the right direction ?
EDIT1:
I have added in CMS_TEMPLATES:
CMS_TEMPLATES = (
## Customize this
('page.html', 'Page'),
('feature.html', 'Page with Feature'),
('index.html', 'oriel.io') # this is what I added
)
but nothing happened.
Add your templates to CMS_TEMPLATES in your settings file.
I recently met the same problem! So let me try to explain
1) You should extend PageAdmin in admin.py
In admin side, when you want to choose template for page ('advanced settings') it will call AdvancedSettingsForm by default. but we must to extend too to give your templates.
class ExtendedPageAdmin(PageAdmin):
def get_form_class(self, request, obj=None, **kwargs):
if 'advanced' in request.path_info:
return ExtendedAdvancedSettingsForm
elif 'permission' in request.path_info:
return PagePermissionForm
elif 'dates' in request.path_info:
return PublicationDatesForm
return self.form
and DO NOT forget unregister and register
admin.site.unregister(Page)
admin.site.register(Page, ExtendedPageAdmin)
2) OK) You have choosen ('advanced settings') and there must be choice among your custom templates.
class ExtendedAdvancedSettingsForm(AdvancedSettingsForm):
def __init__(self, *args, **kwargs):
super(ExtendedAdvancedSettingsForm, self).__init__(*args, **kwargs)
template_choices = [(x, _(y)) for x, y in get_cms_setting('TEMPLATES')]
self.fields['template'] = forms.ChoiceField(choices=template_choices)
3) Ok, wee see custom templates for page, but there will be error if you want to save it. It's because of Page model. It looks like this:
#python_2_unicode_compatible
class Page(six.with_metaclass(PageMetaClass, MP_Node)):
"""
A simple hierarchical page model
"""
...
template_choices = [(x, _(y)) for x, y in get_cms_setting('TEMPLATES')]
...
template = models.CharField(_("template"), max_length=100,
choices=template_choices, default=TEMPLATE_DEFAULT
help_text=_('The template used to render the content.'))
4) So you should change template_choice during init the Page object. Let's use signals
def after_page_init(sender, instance, **kwargs):
instance._meta.get_field_by_name('template')[0]._choices = []
def patch_cms_page():
from cms.models import Page
from django.db.models.signals import post_init
post_init.connect(after_page_init, sender=Page)
and finally call patch_cms_page() in urls.py )
I was really confused why I was receiving Http404 error. To be more clear heres my code:
My app named books
views.py
from django.shortcuts import render_to_response
from django.http import Http404
from django.template import RequestContext
from books.models import *
def index(request):
title = 'Book Gallery'
books = Book.objects.all().order_by('-id')
lang_list = Lang.objects.all().order_by('-lang')
template = 'books/index.djhtml'
context = {'books': books, 'title': title, 'lang_list': lang_list}
return render_to_response( template, context, context_instance=RequestContext(request) )
def by_book_slug(request, bookslug):
slug = bookslug
try:
book = Book.objects.get(slug=slug)
except:
raise Http404
title = book.name
template = 'books/singlebook.djhtml'
context = {'book': book, 'title': title}
return render_to_response( template, context, context_instance=RequestContext(request) )
def by_lang_slug(request, langslug):
filter = langslug
try:
language = Lang.objects.get(slug=filter)
except:
raise Http404
lang_list = Lang.objects.all().order_by('-lang')
books = Book.objects.filter(lang=language).order_by('-id')
title = language
template = 'books/by_language.djhtml'
context = {'books': books, 'title': title, 'filter': filter, 'lang_list': lang_list}
return render_to_response( template, context, context_instance=RequestContext(request) )
urls.py inside my book app folder
from django.conf.urls import patterns, include, url
from books import views
urlpatterns = patterns('',
url(r'(?P<langslug>.*)/$', views.by_lang_slug, name='by_lang'),
url(r'(?P<bookslug>.*)/$', views.by_book_slug, name='by_book'),
url(r'^$', views.index, name='book_gallery'),
)
link that pertains to langslug url conf works but those links for bookslug url conf does not work. When I try to switch them down and up, one of them work and the other one is not.
I really don't know what is happening here. Any help will be a great help. Thanks.

I have included a raise Http404 method when specified slug does not match to any query in the database. The thing I was confused about is, when I try to switch langslug and bookslug urlconf, links that are associated to one of these url works and the other is not.
Based on your url, if I put value on it even though they have different view, the result would be:
urlpatterns = patterns('',
# http://localhost:8000/English/
url(r'(?P<langslug>.*)/$', views.by_lang_slug, name='by_lang'),
# http://localhost:8000/YourBook/
url(r'(?P<bookslug>.*)/$', views.by_book_slug, name='by_book'),
# http://localhost:8000/
url(r'^$', views.index, name='book_gallery'),
)
Have you notice it, they have the same pattern so the first view execute is the by_lang_slug. So if you change the order the other one will be executed first. The best thing to do about it is to have a unique url name.
urlpatterns = patterns('',
# http://localhost:8000/lang/English/
url(r'lang/(?P<langslug>.*)/$', views.by_lang_slug, name='by_lang'),
# http://localhost:8000/book/YourBook/
url(r'book/(?P<bookslug>.*)/$', views.by_book_slug, name='by_book'),
# http://localhost:8000/
url(r'^$', views.index, name='book_gallery'),
)
Now they are different....
I'd like to deliver special versions of my django site for different (mobile-)browser.
What are possible solutions to do this?
In your view, do smthg like this
def map(request, options=None, longitude=None, latitude = None):
if 'iPhone' in request.META["HTTP_USER_AGENT"]:
user_agent = 'iPhone'
elif 'MSIE' in request.META["HTTP_USER_AGENT"]:
user_agent ='MSIE'
else: user_agent=''
print user_agent
return render_to_response('map/map.html',
{
'user_agent': user_agent
})
and in your template
{% ifnotequal user_agent "iPhone" %}
{% ifequal user_agent "MSIE" %}
{% include 'map/map_ie.html' %}
{% else %}
{% include 'map/map_default.html' %}
{% endifequal %}
{% else %}
{% include 'map/map_iphone.html' %}
{% endifnotequal %}
best practice: use minidetector to add the extra info to the request, then use django's built in request context to pass it to your templates like so.
from django.shortcuts import render_to_response
from django.template import RequestContext
def my_view_on_mobile_and_desktop(request)
.....
render_to_response('regular_template.html',
{'my vars to template':vars},
context_instance=RequestContext(request))
then in your template you are able to introduce stuff like:
<html>
<head>
{% block head %}
<title>blah</title>
{% if request.mobile %}
<link rel="stylesheet" href="{{ MEDIA_URL }}/styles/base-mobile.css">
{% else %}
<link rel="stylesheet" href="{{ MEDIA_URL }}/styles/base-desktop.css">
{% endif %}
</head>
<body>
<div id="navigation">
{% include "_navigation.html" %}
</div>
{% if not request.mobile %}
<div id="sidebar">
<p> sidebar content not fit for mobile </p>
</div>
{% endif %>
<div id="content">
<article>
{% if not request.mobile %}
<aside>
<p> aside content </p>
</aside>
{% endif %}
<p> article content </p>
</aricle>
</div>
</body>
</html>
