From c7b2c59ef61a7ea8f1df4a488a39534090b3c9fa Mon Sep 17 00:00:00 2001 From: Michael Chihlas Date: Sat, 7 Feb 2026 23:06:13 -0500 Subject: [PATCH] feat: implement tree sharing, draft trees, and session-to-tree conversion (Issues #16, #25, #17) Backend features: - Tree sharing via secure tokens with expiration (Issue #16) - Draft tree status with conditional validation (Issue #25) - Save session as custom tree with fork tracking (Issue #17) - Tree validation system for publish requirements - Session-to-tree conversion preserving custom steps Database migrations: - 024: Tree sharing (tree_shares table, visibility field) - 025: Tree status field (draft/published) - 25b: Merge migration for indexes New endpoints: - POST /api/v1/trees/{id}/share - Generate share token - GET /api/v1/shared/{token} - Public tree access - POST /api/v1/trees/{id}/can-publish - Validate tree - POST /api/v1/sessions/{id}/save-as-tree - Convert session Test coverage: - 20 tests for draft trees functionality - 14 tests for session-to-tree conversion - 15 tests for tree sharing Co-Authored-By: Claude Sonnet 4.5 --- .../alembic/versions/024_add_tree_sharing.py | 74 ++++ .../versions/025_add_tree_status_field.py | 47 +++ ..._merge_tree_sharing_and_session_indexes.py | 26 ++ backend/app/api/endpoints/sessions.py | 129 +++++- backend/app/api/endpoints/shared.py | 70 ++++ backend/app/api/endpoints/trees.py | 276 ++++++++++++- backend/app/api/router.py | 3 +- backend/app/core/session_to_tree.py | 206 ++++++++++ backend/app/core/tree_validation.py | 151 +++++++ backend/app/models/tree.py | 32 +- backend/app/models/tree_share.py | 60 +++ backend/app/schemas/session.py | 14 + backend/app/schemas/tree.py | 63 ++- backend/tests/test_draft_trees.py | 349 ++++++++++++++++ backend/tests/test_save_session_as_tree.py | 380 ++++++++++++++++++ backend/tests/test_tree_sharing.py | 268 ++++++++++++ 16 files changed, 2141 insertions(+), 7 deletions(-) create mode 100644 backend/alembic/versions/024_add_tree_sharing.py create mode 100644 backend/alembic/versions/025_add_tree_status_field.py create mode 100644 backend/alembic/versions/25b001abd0f7_merge_tree_sharing_and_session_indexes.py create mode 100644 backend/app/api/endpoints/shared.py create mode 100644 backend/app/core/session_to_tree.py create mode 100644 backend/app/core/tree_validation.py create mode 100644 backend/app/models/tree_share.py create mode 100644 backend/tests/test_draft_trees.py create mode 100644 backend/tests/test_save_session_as_tree.py create mode 100644 backend/tests/test_tree_sharing.py diff --git a/backend/alembic/versions/024_add_tree_sharing.py b/backend/alembic/versions/024_add_tree_sharing.py new file mode 100644 index 00000000..ac895ade --- /dev/null +++ b/backend/alembic/versions/024_add_tree_sharing.py @@ -0,0 +1,74 @@ +"""add tree sharing tables + +Revision ID: 024 +Revises: 023 +Create Date: 2026-02-07 + +Adds tree sharing infrastructure: +- visibility field on trees table (private/team/link/public) +- tree_shares: Share tokens for link-based sharing with forking control + +Key features: +- Default existing trees to 'team' visibility +- Share tokens are URL-safe (secrets.token_urlsafe) +- Optional expiration for time-limited shares +- allow_forking flag controls whether recipients can fork shared trees +""" +from typing import Sequence, Union + +from alembic import op +import sqlalchemy as sa +from sqlalchemy.dialects.postgresql import UUID + + +# revision identifiers, used by Alembic. +revision: str = '024' +down_revision: Union[str, None] = '023' +branch_labels: Union[str, Sequence[str], None] = None +depends_on: Union[str, Sequence[str], None] = None + + +def upgrade() -> None: + #
