https://www.loom.com/share/1fd2774a6e2b4138ad9f453c95379076

Summary

• Add bulk_assign_data_rows() method to the Project class, calling the existing bulkAssignDataRows GraphQL mutation
• Add TaskAssignmentStatus enum (FREE, RESERVED) for filtering which data rows can be assigned
• Export TaskAssignmentStatus from the top-level labelbox package

Usage

from labelbox import Client, TaskAssignmentStatus

client = Client(api_key="<your_api_key>")
project = client.get_project("<project_id>")

# Assign data rows to a labeler (only unassigned rows by default)
project.bulk_assign_data_rows(
    user_id="<user_id>",
    data_row_ids=["<data_row_id_1>", "<data_row_id_2>"],
)

# Optionally allow reassigning already-reserved rows
project.bulk_assign_data_rows(
    user_id="<user_id>",
    data_row_ids=["<data_row_id_1>"],
    allowed_statuses=[TaskAssignmentStatus.FREE, TaskAssignmentStatus.RESERVED],
)

Note

Medium Risk
Adds a new Project.bulk_assign_data_rows GraphQL mutation wrapper and new public enum, plus updates CI to use different staging API key secret names; main risk is API/permission mismatches or CI failures due to secret configuration changes.

Overview
Adds bulk data-row assignment to the Python SDK via Project.bulk_assign_data_rows, calling the bulkAssignDataRows GraphQL mutation with optional allowed_statuses filtering.

Introduces and exports TaskAssignmentStatus (FREE, RESERVED), and adds unit + integration tests covering request serialization, empty-input behavior, and status filtering.

Also refactors ApiKey.create_api_key to run validity/time-unit/role input validation earlier (tests updated accordingly), tightens typing in DataRowItemBase.build, and updates GitHub Actions workflow/action matrices to use new staging API key secret identifiers.
