Assembly Line Weaver: Suffolk LIT Lab Document Assembly Line

The Assembly Line Project is a collection of volunteers, students, and institutions who joined together during the COVID-19 pandemic to help increase access to the court system. Our vision is mobile-friendly, easy to use guided online forms that help empower litigants to access the court remotely.

Our signature project is CourtFormsOnline.org.

We designed a step-by-step, assembly line style process for automating court forms on top of Docassemble and built several tools along the way that you can use in your home jurisdiction.

This package contains an automation and rapid prototyping tool to support authoring robust, consistent, and attractive Docassemble interviews that help complete court forms. Upload a labeled PDF or DOCX file, and the Assembly Line Weaver will produce a runnable, clean code, draft of a Docassemble interview that you can continue to edit and refine.

ALWeaver API

When installed on a docassemble server, ALWeaver exposes a custom Flask API:

• POST /al/api/v1/weaver (primary)
• GET /al/api/v1/weaver/jobs/{job_id} (async job polling)
• DELETE /al/api/v1/weaver/jobs/{job_id} (async job cleanup)
• GET /al/api/v1/weaver/openapi.json (OpenAPI spec)
• GET /al/api/v1/weaver/docs (human-readable docs)

The API uses docassemble's API key authentication via api_verify(). The POST endpoint defaults to synchronous behavior, and supports optional asynchronous execution with mode=async (or async=true).

Celery worker configuration

Uploaded-document project generation in the graphical editor and asynchronous API requests require ALWeaver's task module to be registered with Docassemble's global Celery configuration. Add the module to the existing celery modules list in the Docassemble configuration; preserve any modules already listed:

celery modules:
  - docassemble.ALWeaver.api_weaver_worker

After changing the configuration, restart or redeploy both the Docassemble web service and every Celery worker so that they load the same task registry. Blank project creation, ordinary graphical/source editing, and synchronous API calls do not require this module.

ALWeaver checks this setting when its editor module starts and whenever the editor page loads. If it is missing, the server logs a warning and the editor shows a persistent setup notice before a developer selects a file to generate. An attempted background request fails with HTTP 503, a structured async_not_configured API error (or editor_async_not_configured from the graphical editor), and a link back to these instructions. Weaver does not enqueue an unregistered task or fall back to an in-process thread.

The revisioned graphical source-patch API is an opt-in beta. Set WEAVER_ENABLE_PATCH_MODEL: true in the Docassemble configuration (or the same environment variable) to enable it. The default production path remains off until graphical editing paths have migrated to exact source-range commands.

The server-side runtime inspector is also opt-in. Set WEAVER_ENABLE_RUNTIME_INSPECTOR: true to enable owner-scoped target sessions, current-question and variable inspection, scenario seeding, back navigation, and the fixed read-only al_weaver.inspect_* action allowlist. Docassemble remains the only interview runtime.
