Subtopics

Motivation: Subtopics are a key feature of Helix applications. They allow users to organize and categorize their content in a meaningful way. This leads to a more structured and navigable experience for users, making it easier to find the information they need.

How it Works:

• Hierarchical Structure: Subtopics are organized in a hierarchical structure, allowing for deep nesting of content.
• Customizable Names and Descriptions: Users can customize the names and descriptions of subtopics to suit their specific needs.
• Content Organization: Users can assign content to specific subtopics, creating logical groups of related information.
• Search and Navigation: Subtopics are integrated into the Helix search and navigation features, making it easy for users to find the content they need.

Options:

• Creating Subtopics: Users can create new subtopics through the Helix web interface.
• Editing Subtopics: Users can edit the names, descriptions, and content assignments of existing subtopics.
• Deleting Subtopics: Users can delete subtopics, but this will also delete all associated content.

Example:

# Example of a Helix application with subtopics
          ## Main Topic: Python Programming
          ### Subtopic 1: Data Structures
          #### Subtopic 2: Lists
          #### Subtopic 3: Dictionaries
          ### Subtopic 4: Functions
          #### Subtopic 5: Recursion
          

Implementation Details:

• The Subtopic class in the helix package provides the core functionality for managing subtopics.
• Subtopic data is stored in the Helix database.
• Subtopics are integrated with the Helix search and navigation features through the SearchEngine class.

Code Examples:

# Create a new subtopic
          subtopic = Subtopic(name="Data Structures", description="A collection of related data items", parent_topic=main_topic)
          subtopic.save()
          
          # Assign content to a subtopic
          content.subtopic = subtopic
          content.save()
          
          # Retrieve subtopics for a given topic
          subtopics = Topic.objects.get(pk=1).subtopics.all()
          
          # Search for content within a specific subtopic
          results = SearchEngine.search(query="list", subtopic=subtopic)
