fpt-api 0.3.1

A thread-safe wrapper around Flow Production Tracking (formerly ShotGrid) with query field support

fpt-api

A thread-safe wrapper around Flow Production Tracking (formerly ShotGrid) that extends shotgun_api3 to support query field retrieval and parallel processing.

It also supports the retrieval of all Entities of a given Page, applying the Page filters.

Features

• 🔍 Retrieves query fields (not supported in base shotgun_api3)
• 📄 Retrieves all Entities of a given Page, applying the Page filters
• 🧵 Thread-safe operations (not supported in base shotgun_api3)
• ⚡ Parallel processing for improved performance
• 🔄 Streaming results for processing large datasets
• 🔌 Drop-in replacement for basic shotgun_api3 operations
• • Supports dotted query fields, e.g. entity.Shot.sg_assets_count

Installation

From PyPI:

pip install fpt-api
pip install git+https://github.com/shotgunsoftware/python-api.git

From source:

pip install git+https://github.com/ksallee/fpt-api.git
pip install git+https://github.com/shotgunsoftware/python-api.git

Why This Wrapper?

The standard shotgun_api3 library has two main limitations:

1. No support for query field retrieval, which is essential for reporting and analytics
2. Not thread-safe, which can cause issues in multi-threaded applications

This wrapper addresses both issues by:

• Implementing query field retrieval
• Adding thread safety
• Parallelizing query field retrieval for better performance
• Supporting streaming for large result sets

Usage

Basic Usage

from fpt_api import FPT

# Initialize the client
fpt = FPT(
    "https://yourshotgunurl.com",
    script_name="your_script_name",
    api_key="your_script_key"
)

# Find a single shot
shot = fpt.find_one(
    "Shot",
    [["id", "is", 1234]],
    ["code", "sg_status_list", "sg_query_field"]
)

# Find multiple shots (returns all results at once)
shots = fpt.find(
    "Shot",
    [["id", "in", [1234, 12345]]],
    ["code", "sg_status_list", "sg_query_field"]
)

# Stream results one by one
for shot in fpt.yield_find(
    "Shot",
    [["id", "in", [1234, 12345]]],
    ["code", "sg_status_list", "sg_query_field"]
):
    process_shot(shot)  # Process each shot as it becomes ready

# Get the value of a dotted query field
version = fpt.find_one(
    "Version",
    [["id", "is", 1234]],
    ["entity.Shot.sg_assets_count"]
)

# Get all Entities of a given Page, applying the Page filters
for shot in fpt.yield_page_entities(5105):
    print(shot)

API Reference

Check out the Official Shotgun API Reference for more information on the base shotgun_api3 library. FPT does not change the base API, but rather extends it with additional functionality.

Yield all Entities of a given Page, applying the Page filters:

def yield_page_entities(
    self,
    page_id: int,
    additional_filters: Optional[List] = None,
    fields: Optional[List[str]] = None,
) -> Iterator[Entity]:
    """
    Yield entities from a Page, applying the Page filters.

    :param page_id: ID of the Page to process
    :param additional_filters: Additional filters to apply
    :param fields: Fields to retrieve
    :yields: Entities found
    """

Performance Notes

• Query fields are retrieved in parallel using threads
• For standard find(), results are returned after all query fields are retrieved
• yield_find() streams results as they become available
• Connection pooling reduces overhead for multiple requests
