Usage ===== This section provides a comprehensive guide on how to utilize the package's key features, including the functionality of the Django admin panels for managing announcements, announcement categories, audiences, user announcement profile and Manager methods for handling announcements. Admin Site ---------- If you are using a **custom admin site** in your project, you must pass your custom admin site configuration in your Django settings. Otherwise, Django may raise the following error during checks: .. code-block:: shell ERRORS: : (admin.E039) An admin for model "User" has to be registered to be referenced by UserAnnouncementProfileAdmin.autocomplete_fields. To resolve this, In your ``settings.py``, add the following setting to specify the path to your custom admin site class instance .. code-block:: python DJANGO_ANNOUNCEMENT_ADMIN_SITE_CLASS = "path.to.your.custom.site" example of a custom Admin Site: .. code-block:: python from django.contrib.admin import AdminSite class CustomAdminSite(AdminSite): site_header = "Custom Admin" site_title = "Custom Admin Portal" index_title = "Welcome to the Custom Admin Portal" # Instantiate the custom admin site as example example_admin_site = CustomAdminSite(name="custom_admin") and then reference the instance like this: .. code-block:: python DJANGO_ANNOUNCEMENT_ADMIN_SITE_CLASS = "path.to.example_admin_site" This setup allows `dj-announcement-api` to use your custom admin site for it's Admin interface, preventing any errors and ensuring a smooth integration with the custom admin interface. Announcements Admin Panel ------------------------- The ``AnnouncementAdmin`` class provides a comprehensive admin interface for managing announcements in the Django admin panel. The features and functionality are described below: Inline Admin Interfaces ~~~~~~~~~~~~~~~~~~~~~~~ The ``AnnouncementAdmin`` panel includes two inline admin interfaces that allow admins to view and manage related models directly from the announcement page: - ``AudienceInline``: Displays and manages the audiences associated with each announcement. Admins can view or add audience directly within the announcement details page. List Display ~~~~~~~~~~~~ The list view for announcements includes the following fields: - ``ID``: The unique identifier for each announcement. - ``Title``: The announcement title or a summary. - ``Category``: The category of the announcement. - ``Created at``: Creation time of the announcement. - ``Expires at``: Expiration time of the announcement. This view helps admins get a quick overview of the announcements and their current status. Filtering ~~~~~~~~~ Admins can filter the list of announcements based on the following fields: - ``created_at``: Filter by the creation time of the announcement. - ``updated_at``: Filter by the time that the announcement last updated. - ``category``: Filter by announcement category.

Users typically use `Announcement.objects.all()` to retrieve announcements, but other methods are available for querying specific subsets of announcements. Below is an overview of the available methods: Return All Announcements ~~~~~~~~~~~~~~~~~~~~~~~~~ The ``all`` method retrieves all announcements from the database. **Method Signature** .. code-block:: python from django_announcement.models import Announcement Announcement.objects.all() **Returns:** - A ``QuerySet`` of all announcements in the system. **Example Usage:** To retrieve all announcements: .. code-block:: python from django_announcement.models import Announcement all_announcements = Announcement.objects.all() Return Active Announcements ~~~~~~~~~~~~~~~~~~~~~~~~~~~ The ``active`` method retrieves only the announcements that are currently active (published and not expired). **Method Signature** .. code-block:: python from django_announcement.models import Announcement Announcement.objects.active() **Returns:** - A ``QuerySet`` of active announcements. **Example Usage:** To retrieve all active announcements: .. code-block:: python from django_announcement.models import Announcement active_announcements = Announcement.objects.active() Return Upcoming Announcements ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The ``upcoming`` method retrieves announcements that are scheduled to be published in the future. **Method Signature** .. code-block:: python from django_announcement.models import Announcement Announcement.objects.upcoming() **Returns:** - A ``QuerySet`` of announcements scheduled for future publication. **Example Usage:** To retrieve all upcoming announcements: .. code-block:: python from django_announcement.models import Announcement upcoming_announcements = Announcement.objects.upcoming() Return Expired Announcements ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The ``expired`` method retrieves announcements that have already expired. **Method Signature** .. code-block:: python from django_announcement.models import Announcement Announcement.objects.expired() **Returns:** - A ``QuerySet`` of expired announcements. **Example Usage:** To retrieve all expired announcements: .. code-block:: python from django_announcement.models import Announcement expired_announcements = Announcement.objects.expired() Retrieve Announcements by Audience ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The ``get_by_audience`` method retrieves announcements targeted at specific audience(s). **Method Signature** .. code-block:: python from django_announcement.models import Announcement, Audience audiences = Audience.objects.filter(name__icontains="manager") Announcement.objects.get_by_audience(audiences) **Arguments:** - **audiences** (``Audiences``): An audience instance, audience ID, or an iterable of audience instances to filter announcements by. **Returns:** - A ``QuerySet`` of announcements for the given audience(s). **Example Usage:** To retrieve announcements for a specific audience: .. code-block:: python from django_announcement.models import Announcement, Audience specific_audience = Audience.objects.get(id=1) audience_announcements = Announcement.objects.get_by_audience(specific_audience) Retrieve Announcements by Category ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The ``get_by_category`` method retrieves announcements filtered by specific category(s). **Method Signature** .. code-block:: python from django_announcement.models import Announcement, AnnouncementCategory categories = AnnouncementCategory.objects.filter(id__in=[1, 2]) Announcement.objects.get_by_category(categories) **Arguments:** - **categories** (``Categories``): A category instance, category ID, or an iterable of category instances to filter announcements by. **Returns:** - A ``QuerySet`` of announcements for the given category(s). **Example Usage:** To retrieve announcements for a specific category: .. code-block:: python from django_announcement.models import Announcement, AnnouncementCategory specific_category = AnnouncementCategory.objects.get(id=2) category_announcements = Announcement.objects.get_by_category(specific_category) generate_audiences Command -------------------------- The ``generate_audiences`` command dynamically creates audiences based on models related to the ``User``. It allows filtering out specific apps and models through configuration settings, and includes an optional user confirmation step before proceeding. Command Overview ~~~~~~~~~~~~~~~~ This command scans for related models in the ``User`` (excluding those defined in the settings), confirms the list of models with the user, and creates audiences if they don't already exist. It is useful for dynamically creating target audiences for announcements based on your application's data models. Settings ~~~~~~~~ This command is influenced by two key settings: - ``DJANGO_ANNOUNCEMENT_GENERATE_AUDIENCES_EXCLUDE_APPS``: A list of app labels to exclude from the audience generation process. - ``DJANGO_ANNOUNCEMENT_GENERATE_AUDIENCES_EXCLUDE_MODELS``: A list of model names to exclude from the audience generation process. These settings allow for fine-grained control over which models are considered for audience creation. Usage ~~~~~ The command can be run using Django's ``manage.py`` utility: .. code-block:: bash $ python manage.py generate_audiences Optional Arguments ~~~~~~~~~~~~~~~~~~ - ``--skip-confirmation``: Skips the user confirmation prompt and proceeds directly to creating audiences. Example usage: .. code-block:: bash $ python manage.py generate_audiences --skip-confirmation Command Flow ~~~~~~~~~~~~ 1. **Retrieve Related Models**: The command first retrieves all models related to the ``User`` by checking the relationships. It filters out any models and apps specified in the ``DJANGO_ANNOUNCEMENT_GENERATE_AUDIENCES_EXCLUDE_APPS`` and ``DJANGO_ANNOUNCEMENT_GENERATE_AUDIENCES_EXCLUDE_MODELS`` settings. 2. **Prompt for Confirmation**: The command lists the related models found and asks for confirmation from the user to proceed. If the ``--skip-confirmation`` flag is provided, this step is bypassed. 3. **Create Audiences**: For each related model that doesn't already have a corresponding audience, the command creates a new audience and saves it in the database. It checks the existing audiences by their name to avoid duplications. Example Output ~~~~~~~~~~~~~~ When running the command, the following example output might be displayed: .. code-block:: text The following related models were found: 1. User Profile 2. Organization Are these the correct target models? Type 'y' to proceed or 'n' to modify settings: y Created audience: User Profile Created audience: Organization Finished creating audiences! If no new audiences are needed, you would see: .. code-block:: text No new audiences needed to be created. generate_profiles Command ------------------------- The ``generate_profiles`` command assigns users to dynamically created audiences using the ``UserAnnouncementProfile`` model. It ensures that users are correctly associated with audiences based on user-related models in the database. This command should be run after the ``generate_audiences`` command to link users to the relevant audiences. Command Overview ~~~~~~~~~~~~~~~~ This command checks if the audience generation has been completed, then proceeds to create user profiles if they do not already exist. It builds and assigns audience-user relationships dynamically, based on the user-related models detected in the system. Usage ~~~~~ The command can be run using Django's ``manage.py`` utility: .. code-block:: bash $ python manage.py generate_profiles Optional Arguments ~~~~~~~~~~~~~~~~~~ - ``--skip-confirmation``: Skips the user confirmation prompt and proceeds directly to assigning users to audiences. Example usage: .. code-block:: bash $ python manage.py generate_profiles --skip-confirmation Command Flow ~~~~~~~~~~~~ 1. **Check Audience Generation**: The command prompts the user to confirm whether the ``generate_audiences`` command has been run. If this confirmation is not provided (or skipped using the ``--skip-confirmation`` flag), the command exits. 2. **Retrieve Related Users**: The command fetches users related to models detected in the ``User`` by foreign key or related relationships. 3. **Create User Profiles**: If a user does not already have an associated ``UserAnnouncementProfile``, the command creates one. 4. **Assign Audiences**: Audiences are mapped to users based on the related models, and new assignments are created if they do not already exist. This avoids duplicate assignments. Settings Impact ~~~~~~~~~~~~~~~ This command depends on the previous execution of the ``generate_audiences`` command, which creates the necessary audiences. Make sure that step has been completed before running this command. Example Output ~~~~~~~~~~~~~~ When running the command, the following example output might be displayed: .. code-block:: text Ensure you've run the 'generate_audiences' command before proceeding. Have you already run 'generate_audiences'? (yes/no): yes All users have been assigned to existing audiences successfully. If no related users are found or if audiences are missing, you would see: .. code-block:: text No users found related to the provided models. No valid audiences found. Please run 'generate_audiences' first. Exiting... .. note:: Refer to the :doc:`Examples ` section for detailed approaches to automating the assignment of new users to appropriate audiences.
