Implement Blog Post App with Full Functionality

We need to add a new app named blog to our Django project that will manage blog posts, including their creation, update, and deletion. This app should handle various aspects such as permissions, serialization of data, and efficient handling of related models and media files. Detailed requirements for each component are outlined below:

Models

Implement the following models with the specified fields:

• Tags: For categorizing posts. Fields: name.
• Images: To store image files related to blog posts. Fields: image_file, uploaded_at, blog_post (ForeignKey to Blogs).
• Blogs: Main model for blog posts. Fields: title, content, created_at, updated_at, author (ForeignKey to Authors), categories (ManyToMany with Categories), tags (ManyToMany with Tags).
• Categories: For broader categorization of posts. Fields: name.
• Authors: To credit the author of the post. Fields: name, bio.

Permissions

Set up permissions to ensure that only authorized users can create, update, or delete blog posts. Consider using Django's built-in permissions and custom group-based permissions.

Serializers

Create serializers for each model to facilitate the creation, serialization, and deserialization of JSON data for API responses and requests. Ensure that the serializers handle relations appropriately, especially for the ManyToMany and ForeignKey fields.

Views

Develop the views to handle API requests for blog posts, including:

• Listing all blog posts
• Retrieving a single blog post details
• Creating new blog posts
• Updating existing blog posts
• Deleting blog posts

Consider using Django REST Framework's generic views for simplicity and efficiency.

Pre-delete Signals for Images

Implement pre-delete signals for the Images model to ensure that image files are properly deleted from the storage when the corresponding image object is deleted from the database.

Queue for Image/Media Upload

Set up a queue with celery for handling image/media uploads asynchronously to improve performance and user experience. This is especially important for high-traffic sites or when processing large files.

Additionally:

• Ensure all models are registered in the Django admin for easy management.
• Write unit tests for models, views, and serializers to ensure reliability.
• Documentation for API endpoints should be provided for frontend developers.
