Change the name of the "Add" button in Django Admin - django

As we known, there is an "Add" button in each model in django admin site. How can I change the name of it into like "Add Student" to make it customerized.
I have found the add button in the template
{% if has_add_permission %}
{% url cl.opts|admin_urlname:'add' as add_url %}
<el-button size="small" type="primary" icon="el-icon-plus" data-name="add_item"
url="{% add_preserved_filters add_url is_popup to_field %}">
{% trans 'Add' %}
</el-button>
{% endif %}
I change the "{% trans 'Add' %}" and the button's name can be changed, but all the models page Add button are changed. Is there any way to change it just for one model?

Not looking at your code is hard to give an exact answer but you can override any admin template by extending it.
https://docs.djangoproject.com/en/dev/ref/contrib/admin/#overriding-vs-replacing-an-admin-template
Below is an example to extend change_form similarly you can do for any admin form - just find where this add button is and extend it.
{% extends "admin/change_form.html" %}
{% load i18n admin_urls %}
{% block object-tools-items %}
CUSTOM_CODE
{% endblock %}
There might be possibility to do via python code as well but need to see code for it

Django extra button in a model's changelist for Django Admin

So I want to add an extra button in my Fun model's changelist_view which when pressed, performs a function and redirects me to a new page. I don't want to have this function for every app nor do I want for every model, only the Fun model. And I will be using Django Admin to view this changelist, just a side note.
Can anyone suggest anything? Thanks.
Codes in fun/admins.py
from django.contrib import admin
from .models import Fun
#admin.register(Fun)
class FunAdmin(admin.ModelAdmin):
change_list_template = 'fun/admin_changelist.html'
and for the fun/admin_changelist.html template:
{% extends "admin/change_list.html" %}
{% load i18n admin_static admin_list %}
{% block result_list %}
The custom button
{% if action_form and actions_on_top and cl.full_result_count %}{% admin_actions %}{% endif %}
{% result_list cl %}
{% if action_form and actions_on_bottom and cl.full_result_count %}{% admin_actions %}{% endif %}
{% endblock %}
Overriding the admin templates is perfectly fine, but replacing them (completely) is not recommended; So we will just override the part that we need (here I assume your button will be located in the top of the list, so I only override the result_list block)
Then you should have url with name="your-url-name here" that is connected to a view.
Check the docs for more details

Overridding Django Admin's object-tools bar for one Model

I am looking for the solution. I think a lot of different examples have confused me a little. I want to override the object-tools template in the Django admin.
I have one button on my model's tools:
I need one other same type of button "Upload file". This should redirect me to the another view which I want to design myself in the same admin base template (with just one upload file control).
[A]
Move "django.contrib.admin" in your INSTALLED_APPS to end of INSTALLED_APPS.
You can make template file
<your_app>/templates/admin/<your_app>/<your_model>/change_list.html
source code:
{% extends "admin/change_list.html" %}
{% block object-tools-items %}
<li>
<a href="<your-action-url>" class="addlink">
Upload file
</a>
</li>
{{ block.super }}
{% endblock %}
[B]
Add change_list_template into your ModelAdmin.
class MyModelAdmin(admin.ModelAdmin):
change_list_template = '<path-to-my-template>.html'
And write template like [A] source code.
It has become lot easier to accomplish what you're looking for since this question has been asked the first time.
The Django documentation has a section on how to override admin templates. To add a button to the changelist object tools, follow these steps:
Copy Django's version of the change_list_object_tools.html template file into your project's or app's template folder: templates/admin/<app>/<model>/change_list_object_tools.html.
You can obtain the file form your virtual env's site-packages folder:
cp $VIRTUAL_ENV/lib/python3.8/site-packages/django/contrib/admin/templates/admin/change_list_tools.html templates/admin/$APP/$MODEL/
Note that you might need to adjust the path to site-packages for your Python version.
Now open the template file. It will look liek this:
{% load i18n admin_urls %}
{% block object-tools-items %}
{% if has_add_permission %}
<li>
{% url cl.opts|admin_urlname:'add' as add_url %}
<a href="{% add_preserved_filters add_url is_popup to_field %}" class="addlink">
{% blocktrans with cl.opts.verbose_name as name %}Add {{ name }}{% endblocktrans %}
</a>
</li>
{% endif %}
{% endblock %}
Add the link to your custom view:
…
{% if has_add_permission %}
<li><a class="addlink" href="{% url 'upload-file' %}">Upload file</a></li>
<li>
…
That's it! If you didn't know: you can add custom views and URLs to a ModelAdmin using ModelAdmin.get_urls() (docs). To not have to hardcode your custom admin URLs, you can of course reverse them (docs).
You can try to use https://github.com/texastribune/django-object-actions.
This will allow you to add buttons with custom logic. Though, I'm not sure whether you'll be able to a buttom for your list screen, as I did it only for a model-edit page.

Factorizing a header menu in Django template

I'm building a website using django with a header on top of every page, which basically is a menu with a few links, constant throughout the pages.
However, depending on the page you're on I'd like to highlight the corresponding link on the menu by adding the class "active". To do so, I am currently doing as follow: each page has a full menu block that integrates within a general layout, which does NOT contain the menu. For exemple, page2 would look like this:
{% extends "layout.html" %}
{% block menu %}
<li>Home</li>
<li>page1</li>
<li class="active">page2</li>
<li>page3</li>
{% endblock %}
The problem is that, beside from that solution being not so pretty, every time I want to add a link to the header menu I have to modify each and every page I have. Since this is far from optimal, I was wondering if any of you would know about a better way of doing so.
Thanks in advance!
You can create a custom templatetag:
from django import template
from django.core.urlresolvers import reverse, NoReverseMatch, resolve
register = template.Library()
#register.simple_tag
def active(request, view_name):
url = resolve(request.path)
if url.view_name == view_name:
return 'active'
try:
uri = reverse(view_name)
except NoReverseMatch:
uri = view_name
if request.path.startswith(uri):
return 'active'
return ''
And use it in the template to recognize which page is loaded by URL
<li class="{% active request 'car_edit' %}">Edit</li>
If you have a "page" object at every view, you could compare a navigation item's slug to the object's slug
navigation.html
<ul>
{% for page in navigation %}
<li{% ifequal object.slug page.slug %} class="active"{% endifequal %}>
{{ page.title }}
</li>
{% endfor %}
</ul>
base.html
<html>
<head />
<body>
{% include "navigation.html" %}
{% block content %}
Welcome Earthling.
{% endblock %}
</body>
</html>
page.html
{% extends "base.html" %}
{% block content %}
{{ object }}
{% endblock %}
Where navigation is perhaps a context_processor variable holding all the pages, and object is the current PageDetailView object variable
Disclaimer
There are many solutions for your problem as noted by Paulo. Of course this solution assumes that every view holds a page object, a concept usually implemented by a CMS. If you have views that do not derive from the Page app you would have to inject page pretenders within the navigation (atleast holding a get_absolute_url and title attribute).
This might be a very nice learning experience, but you'll probably save loads time installing feinCMS or django-cms which both define an ApplicationContent principle also.
You may use the include tag and pass it a value which is the current page.
For example, this may be a separate file for declaring the menu template only:
menu.html
{% if active = "a" %}
<li>Home</li>
{% if active = "b" %}
<li>page1</li>
{% if active = "c" %}
<li class="active">page2</li>
{% if active = "d" %}
<li>page3</li>
And call this from within your template like this:
{% include 'path/to/menu.html' with active="b"%} # or a or c or d.
Hope it helps!

Django-CMS show_placeholder not working as expected

I'm working on a site where the footer content is shared across all pages. What is the best way to do in Django-CMS?
I tried using show_placeholder tag, but it somehow didn't work. A little more details on what I did:
First, I have a {% placeholder footer_info %} in base.html. Then I add a page called "Home" (template homepage.html) in django admin and put some text under footer_info as a Text plugin. As the accepted answer in this question suggested (http://stackoverflow.com/questions/3616745/how-to-render-django-cms-plugin-in-every-page),
I add
{% placeholder footer_info or %}
{% show_placeholder footer_info "Home" %}
{% endplaceholder %}
In a template called services.html which I used as the template for page Services.
However, the content in home page is not showing up in services page. I also tried adding an id home_cms_page to home page in the Advanced option area, so that I can reference it in services.html like this:
{% placeholder footer_info or %}
{% show_placeholder footer_info "home_cms_page" %}
{% endplaceholder %}
But the content is still not showing up.
Could anyone tell me what I am doing wrong? And is this the best way of getting some content from a page across all other pages (and I have to add show_placeholder in every other page)?
Thank you
EDIT:
It is not a multilingual site. I commented out 'cms.middleware.multilingual.MultilingualURLMiddleware', because the only language I use on the site is English.
I have this in my base.html:
{% load cms_tags sekizai_tags %}
<!-- all the rest of the HTML markups -->
<div class="span4">
{% placeholder footer_info %}
</div>
Then I added a page in the admin called "Home" with a Text plugin and an id of "home_cms_page".
The following is in my services.html:
{% extends "base.html" %}
{% load cms_tags %}
{% block base_content %}
{% placeholder services_info %}
{% endblock base_content %}
{% block page_content %}
Home page
{% endblock page_content %}
{% placeholder "footer_info" or %}
{% show_placeholder "footer_info" "home_cms_page" %}
{% endplaceholder %}
Read the documentation:
If you know the exact page you are referring to, it is a good idea to
use a reverse_id (a string used to uniquely name a page) rather than a
hard-coded numeric ID in your template. For example, you might have a
help page that you want to link to or display parts of on all pages.
To do this, you would first open the help page in the admin interface
and enter an ID (such as help) under the ‘Advanced’ tab of the form.
Then you could use that reverse_id with the appropriate templatetags:
{% show_placeholder "right-column" "help" %}
I added "index" in the advanced options of the index page, and added {% show_placeholder "banner" "index" %} in the base template. It all works.

Django change the admin page label 'Auth' to 'Authentication'

How can i change the display label Auth in the Django admin dashboard to Authentication?
There is currently no easy/elegant way to do this. Customisable app-labelling has been a sore point for some time. You can override admin/index.html and inject some javascript code to change the labelling. Note that you could also change admin.site.index_template to something like "admin/my_index.html", which can then use {% extends "admin/index.html" %} to keep things DRYer.
Of course there are other areas in the admin that "Auth" will appear also, such in "admin/app_index.html", the breadcrumbs, etc...
I imagine if your overwriting admin/index.html you could hard code the logic in the template instead of any javascript:
<caption><a href="{{ app.app_url }}" class="section">
{% ifequal app.name "Auth" %}
{% trans 'Authentication' %}
{% else %}
{% blocktrans with app.name as name %}{{ name }}{% endblocktrans %}
{% endifequal %}
</a></caption>
