GET list of child categories by selected Category by ID

[lobsam]

Introduction

The OpenPecha backend has a Categories API at /v2/categories/ that manages hierarchical categories for organizing texts. Categories support multi-language localization and belong to specific applications.

Requirement Request from Webuddhist

For Webuddhist to get all child categories of a selected category, you would need:

• GET /v2/categories/{category_id} endpoint that returns:

  • The category's full details (id, title, description, parent_id)
  • The category's children list (already included in the children field)

• This would allow Webuddhist to:

  • Fetch a specific category by ID
  • Get its children IDs from the children field
  • Optionally fetch those children's details if needed

Tasks

• Create new endpoint to get list of child categories of selected category by ID
• write a test case for api endpoint
