I made in my base.html (which will be inherited from all other templates) this:
<a href="/./">
{% placeholder "Logo-Image" or %}
There is no Logo image yet.
{% endplaceholder %}
</a>
I was in Startpage and uploaded a Logo image, worked well. but once I navigated to another pages, the uploaded logo isnot there, instead i see: There is no Logo image yet.
How can I make this placeholder also inheritable?
I tried in another page this:
{% show_placeholder "Logo-Image" inherit %}
but not a single sign of success
I solved the issue. Django CMS has since version 3.0 a new tag called:
static_placeholder
to make it work:
just do in your base.html
{% static_placeholder "logo" or %}
There is no Logo image yet.
{% endstatic_placeholder %}``
and all other pages inherit this.

I'm probably missing something very obvious but can't see anything in the documentation. I have a carousel with a and each will hold an image. However I've added 6 but I want to add an if statement so if an Image has not been added you don't see a blank space, where there is no content inside the .
Here is what i've tried so far:
{% if "Carousel 1" %}
<li>
{% placeholder "Carousel 1" %}
</li>
{% endif %}
Attempt 2:
{% placeholder "Carousel 1" as cara1 %}
{% if cara1 %}
<li>
{{ cara1 }}
</li>
{% endif %}
Not sure if there is something differnt i need to be doing for the django-cms template tags?
Any help would be much appreciated. Docs here - http://docs.django-cms.org/en/latest/advanced/templatetags.html#placeholder
Not to be rude, but your approach is way, way off :)
Placeholders hold Content Plugins. Content Plugins are responsible for how they render their contents.
My advice would be to create or find a carousel content type plugin. This plugin will hold multiple images or "CarouselImage" model instances that you can iterate over, and also specify a template with which to render itself.
In this template resides the conditional statement you're wanting to check for. Placeholders are just that - places held for content plugins.
I have created a DJANGO blog-engine which takes my post and the template parses it for html tags. links etc.. are working but it does not load image file and instead shows the 'alternative' . I have tried the tag in separate html files and it is otherwise. Just not displaying image from inside a django blog post.
Relevant portions of the template file :
{% include 'blog/header.html' %}
</aside>
<section id ="content">
<article>
{%for post in posts %}
<h2>{{ post.title }}</h2>
<h3>{{ post.created}}</h3>
<p>
{{ post.body|safe }}<br>
</p>
<h3>By {{ post.author }}</h3>
I am copy-pasting the post in question
<---- text here ------------------>
GDCM::Directory
<img src="/home/usman/www/deejay/blog/static/images/dicomdir.png" />
This is it
Interestingly, the 'a' tag works fine but the 'img' tag is not working. I have tried many variations but i want some inline code to display simple html tag, alternatively of course i will resort to it programmatically by passing some variable to the template from inside the post to let it know where to position the image.
Your problem is here: {{ post_get_absolute_url }}. You should use {{ post.get_absolute_url }}.
The better way is to call the URL of the image directly; that way you maintain your URLs in urls.py and not in your model code. It makes your app more portable.
Take your image field name value from your model, and then {{ post.image.url }}. For example, if your model is:
class Post(models.Model):
img = models.ImageField(upload_to='images')
Then you would use {{ post.img.url }}
Problem solved when I replaced the full address with
<img src="/static/images/dicomdir.png"/>
On development server as well as on production. What helped was that I looked at the Dev-server responses on my terminal and was able to figure out the url.
Is there any functionality in admin site that allow to implement for every add/change form cancel button, that redirects me to list of that form objects. I mean some general solution for any form.
Add admin/submit_line.html in your project's templates directory. Use the code from the default submit_line.html, and add your cancel button. You can link it to just "../" to make it always just go up one level. Then do any necessary CSS styling to make it look right.
Create a file: yourapp/templates/admin/submit_line.html
I use Bootstrap, but you can change this easily
{% extends "admin/submit_line.html" %}
{% block submit-row %}
{{ block.super }}
Cancel
{% endblock %}
Be sure that your application is above "admin" in INSTALLED_APPS.
Looks like this in German locale:
<input type="button" name="Cancel" value="Cancel">
You can this line anywhere inside admin/submit_line.html
I want to make a very small change to the Django admin logout page.
I know how to use templates to override the Django admin templates, so I have tried to do the same thing with the logout file.
I have set up a new template at templates/registration/logged_out.html. The content of this file is as follows:
{% extends "registration/logged_out.html" %}
{% block content %}
<p>Thanks for using the site.</p>
<p>Log in again</p>
<p>Return to the home page</p>
{% endblock %}
However, something is definitely wrong, because when I try to log out of admin, the site stops running.
I've found the Django docs page recommending the use of AdminSite for changes to the base template and logout pages, but is this really necessary for such a tiny change?
If so, does anyone have an example of how I might set up the logout template? I'm rather intimidated by the instructions for AdminSite.
Thanks.
The reason of manage.py runserver termination is an inheritance loop.
Django loads "registration/logged_out.html" and that it tries to load it's parent: "registration/logged_out.html". Unfortunately parent is the same template and so we end up on the template inheritance loop.
Manage.py will terminate with some variant of stack overflow error...
You can easily escape the issue by extending the parent of original "registration/logged_out.html" -> "admin/base_site.html". I.e:
{% extends "admin/base_site.html" %}
{% load i18n %}
{% block breadcrumbs %}<div class="breadcrumbs">{% trans 'Home' %}</div>{% endblock %}
{% block content %}
<p>Thanks for using the site.</p>
<p>Log in again</p>
<p>Return to the home page</p>
{% endblock %}
You're getting a template import loop. The template loader won't load the base template form wherever you've got Django installed, because it sees that you have that template in your project's template folder.
I think you'll need to copy the log out template from where you have Django installed to your project's template folder. Unfortunately that's the only way that seems to work. This method also means that if updates are made to the Django admin templates, you'll have to manually apply them to your modified templates.
On my django site, I decided to just use the admin templates for the UI, but I made a few tweaks like the site name, color, etc. even my custom views just extend admin/base_site.html I did this by creating templates/admin/base_site.html with the following code:
{% extends "admin/base.html" %}
{% load i18n %}
{% block title %}{{ title }} | {% trans 'Company Name' %}{% endblock %}
{% block extrastyle %}
<style>
#header{ background-color: #a67d3d; border-bottom: solid 3px #f5deb3; }
#branding h1{ color: #fff; }
</style>
{% endblock %}
{% block branding %}
<h1 id="site-name">{% trans 'My company' %}</h1>
{% endblock %}
{% block breadcrumbs %}
{% include "breadcrumb.html" %}
{% endblock %}
The entire admin site has my new title and colors. However, you can see I tried replacing the breadcrumbs bar with my own breadcrumb.html (which contains a custom nav bar). This only works on custom views that extend admin/base_site.html. the normal admin views don't replace the breadcrumbs (but they do have the new colors, company title, etc.). I can't figure out why this one piece isn't working? Moreover, I have a few custom change_form.html files. These also have the style changes, but no custom nav bar. But, if I put in the breadcrumbs block in these pages, it shows up just fine on those pages.
I worked around this by copying the original base.html file into my project's '/templates/admin/' folder, deleted the breadcrumbs block, added a "mynav" block, put my navbar there. This way my nav bar shows up on all pages, and when the lower pages try to put in a breadcrumb there's no block for them and it doesn't show up.
I don't like doing it this way but i can't think of another way. The way suggested by lazerscience would work, but I'd have to do an include in every single template (change_form, change_list, etc.). For others, i should mention, there is a "nav-global" block, but my navbar uses lists/css/jscript to display slideout menus and these menus weren't showing up if i put it in that block, not sure exactly why.
The other admin templates, eg. change_form.html override the breadcrumbs block themselves, so you need to override it also in these templates (=override them and define your block in there).
