Customizing Django Admin Login Page Title

You're encountering a common issue with the Django admin login page. The site_header, site_title, and index_title attributes do work correctly after login, but they don't affect the login page itself in the same way.

Why This Happens

The login page is rendered before the user is authenticated, and the context for the login page is handled differently than the authenticated admin pages.

Solutions

You have two main options to customize the login page title:

Option 1: Override the Login Template

1. Create a custom template directory structure in your project:

   templates/
   └── admin/
       └── login.html
   

2. Make sure your template directory is properly configured in settings.py:

   PYTHONCopied
   TEMPLATES = [
       {
           "BACKEND": "django.template.backends.django.DjangoTemplates",
           "DIRS": [BASE_DIR / "templates"],  # Make sure this points to your templates directory
           "APP_DIRS": True,
           # ... other settings ...
       },
   ]

3. Copy the original login.html from Django's source and modify it, or create a custom one that extends the original but changes the title.

Option 2: Create a Custom AdminSite

This is the more comprehensive approach:

PYTHONCopied
from django.contrib.admin import AdminSite

class CustomAdminSite(AdminSite):
    site_header = 'سایت آرتا شبکه صنعت رایان'
    site_title = 'سایت آرتا شبکه صنعت رایان'
    index_title = 'پنل مدیریت'
    login_template = 'admin/custom_login.html'  # Path to your custom login template

custom_admin_site = CustomAdminSite(name='custom_admin')

# Then register your models with this custom admin site
# custom_admin_site.register(YourModel)

# In urls.py
urlpatterns = [
    path('admin/', custom_admin_site.urls),
    # ... other URL patterns ...
]

With this approach, you'll need to create a custom login template and register all your models with the custom admin site.

Option 3: Override base_site.html

Since the login template extends admin/base_site.html, you can also override just that template:

1. Create templates/admin/base_site.html
2. Add your customized content:

   HTMLCopied
   {% extends "admin/base.html" %}
   
   {% block title %}{{ title }} | {{ site_title|default:_('سایت آرتا شبکه صنعت رایان') }}{% endblock %}
   
   {% block branding %}
   <div id="site-name"><a href="{% url 'admin:index' %}">{{ site_header|default:_('سایت آرتا شبکه صنعت رایان') }}</a></div>
   {% if user.is_anonymous %}
   {% include "admin/color_theme_toggle.html" %}
   {% endif %}
   {% endblock %}

This is often the simplest approach as it will affect both the login page and the authenticated admin pages.

Remember that template overrides take precedence over the AdminSite attributes, so this approach should work regardless of what you've set in urls.py.
