You can also install a specific branch: pip install -e package is now installed in your project and you can find the code.Django is an implementation of the web frameworks concept. You can install the package in the "editable" mode like this: pip uninstall django-solo # just in case. SOLO_CACHE_PREFIX = 'solo' Getting the codeĬheck out the latest development version anonymously with: $ git clone git:///lazybird/django-solo.git SOLO_CACHE_TIMEOUT = 60 * 5 # 5 mins Cache prefix The singleton object can be retrieved from template by giving the Django modelĭotted path: SOLO_CACHE = 'local'Ĭaching will be disabled if set to None. If you wish to disable the skipping of the object list page, and have the defaultīreadcrumbs, you should set SOLO_ADMIN_SKIP_OBJECT_LIST_PAGE to False in your settings. From the edit page, we cannot delete the object (4) nor can we add a new one (5).The edit page has a modified breadcrumb (3) to avoid linking to the.Need for an intermediary object list page, since there's only one object. The link to the configuration page (2) directly goes to the form page - no.The configuration object can only be changed, there's no link for "add" (1).In the admin home page where all applications are listed, we have a configĪpplication that holds a singleton model for site configuration.The standard Django admin does not fit well when working with singleton,įor instance, if you need some global site settings to be edited in the admin.ĭjango Solo provides a modified admin for that. manage.py test solo -settings=Īnd from within tox: python -m pip install tox Add solo or to your INSTALLED_APPS setting.Install the package using pip install django-solo.This application requires Django 2.2, 3.2, or 4.0. This can be done by setting singleton_instance_id property on the model: class SiteConfiguration ( SingletonModel ): singleton_instance_id = 24 # (.) Installation If you're changing an existing model (which already has some objects stored in the database) to a singleton model, you can explicitly provide the id of the row in the database for django-solo to use. That's because Django Solo uses the verbose_name instead. In your model, note how you did not have to provide a verbose_name_plural field. get () # get_solo will create the item if it does not already exist config = SiteConfiguration. models import SiteConfiguration config = SiteConfiguration. register ( SiteConfiguration, SingletonModelAdmin ) # There is only one item in the table, you can get it this way: from. BooleanField ( default = False ) def _str_ ( self ): return "Site Configuration" class Meta : verbose_name = "Site Configuration" # admin.py from ntrib import admin from solo.admin import SingletonModelAdmin from config.models import SiteConfiguration admin. CharField ( max_length = 255, default = 'Site Name' ) maintenance_mode = models. Usage Example # models.py from django.db import models from solo.models import SingletonModel class SiteConfiguration ( SingletonModel ): site_name = models. There are many cases where it makes sense for the parent in a one to many relationship to be limited to a single instance. Like the use case below where you have a 'Home Slider" that has many "Slides". By enabling caching, the database is not queried intensively.ĭjango Solo is also great for use with singleton objects that have a one to many relationship.You can retrieve the object from templates.You get an admin interface that's aware you only have one object.django-solo gives helper parent class for your model and the admin classes.You define the model that will hold your singleton object.Solo helps you enforce instantiating only one instance of a model in django. | / | instead of having them in Django settings.py. | \/ | settings that you want to edit from the admin | >=)'> | Singletons are useful for things like global
