📝 Issue: Bulk Update Support for Repository Layer

[CoderMungan]

🚀 Feature Request: Implement Bulk Update in BaseRepository

Description

Currently, BaseRepository supports individual updates via the update(obj_id, data) method. However, bulk updates are not supported, which can be inefficient for updating multiple records at once.

Proposed Solution

Add a method bulk_update(self, updates: List[dict], key_field: str = "id") to allow updating multiple objects in a single query.

Expected Behavior
• Accepts a list of dictionaries, where each dictionary contains the primary key (id or key_field) and the fields to update.
• Uses Django’s bulk_update() to update records efficiently.

Alternatives Considered
• Using multiple .update() calls inside a loop (inefficient).
• Using raw SQL queries (not Django ORM friendly).

Impact

✅ Reduces database queries significantly for batch updates.
✅ Improves performance in high-load applications.
✅ Keeps repository logic clean and efficient.

Looking forward to feedback and suggestions! 🚀
