Material Admin

Material Admin is based on Google’s Material Design and supports the latest Django versions.

Installation:

1. Install Material Admin:

   pip install django-material-admin

2. Add material to INSTALLED_APPS in settings.py before django.contrib.admin:

   INSTALLED_APPS = [
       'material',
       'django.contrib.admin',
       # other apps
   ]

3. Start the development server and check the admin interface.

TemplateSyntaxError at /admin/toggle_app/toggleitem/6/change/
Invalid filter: 'length_is'

1. Create Your Custom Filter

1. Define the Filter Create a templatetags folder (if it doesn’t already exist) in your app, and include an __init__.py file inside it. Add a custom_filters.py file.

   Folder structure:

   toggle_app/
   ├── templatetags/
   │   ├── __init__.py
   │   ├── custom_filters.py
   

   In custom_filters.py, define the length_is filter:

   from django import template
   
   register = template.Library()
   
   @register.filter
   def length_is(value, length):
       """Check if the length of the value is equal to the given length."""
       try:
           return len(value) == int(length)
       except (ValueError, TypeError):
           return False

---

2. Add to builtins in settings.py

To make the custom filter globally available without needing to {% load custom_filters %} in each template, register it as a built-in template tag library.

1. In your settings.py, add:

   TEMPLATES = [
       {
           'BACKEND': 'django.template.backends.django.DjangoTemplates',
           'DIRS': [],
           'APP_DIRS': True,
           'OPTIONS': {
               'context_processors': [
                   'django.template.context_processors.debug',
                   'django.template.context_processors.request',
                   'django.contrib.auth.context_processors.auth',
                   'django.contrib.messages.context_processors.messages',
               ],
               "builtins": ["toggle_app.templatetags.custom_filters"],  # Add your custom filters here
           },
       },
   ]
