From 1608020b696c9d8350324877606c06e18831c0ee Mon Sep 17 00:00:00 2001 From: Zachary Hampton Date: Wed, 5 Nov 2025 10:09:58 -0800 Subject: [PATCH] Add last_status_change_date field for hour-level precision in date filtering MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Enhances pending_date and last_sold_date with hour-level precision by introducing the last_status_change_date field. This allows for more accurate filtering of PENDING and SOLD properties when using past_hours parameter. Includes comprehensive tests and version bump to 0.7.1. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- README.md | 1 + homeharvest/core/scrapers/models.py | 1 + homeharvest/core/scrapers/realtor/__init__.py | 17 +- .../core/scrapers/realtor/processors.py | 20 ++ homeharvest/core/scrapers/realtor/queries.py | 1 + homeharvest/utils.py | 3 +- poetry.lock | 6 +- pyproject.toml | 2 +- tests/test_realtor.py | 209 +++++++++++++++++- 9 files changed, 253 insertions(+), 7 deletions(-) diff --git a/README.md b/README.md index dac3583..ae4c3f8 100644 --- a/README.md +++ b/README.md @@ -324,6 +324,7 @@ Property │ ├── pending_date # datetime (full timestamp: YYYY-MM-DD HH:MM:SS) │ ├── sold_price │ ├── last_sold_date # datetime (full timestamp: YYYY-MM-DD HH:MM:SS) +│ ├── last_status_change_date # datetime (full timestamp: YYYY-MM-DD HH:MM:SS) │ ├── last_sold_price │ ├── price_per_sqft │ ├── new_construction diff --git a/homeharvest/core/scrapers/models.py b/homeharvest/core/scrapers/models.py index 5db299d..833e99d 100644 --- a/homeharvest/core/scrapers/models.py +++ b/homeharvest/core/scrapers/models.py @@ -192,6 +192,7 @@ class Property(BaseModel): list_date: datetime | None = Field(None, description="The time this Home entered Move system") pending_date: datetime | None = Field(None, description="The date listing went into pending state") last_sold_date: datetime | None = Field(None, description="Last time the Home was sold") + last_status_change_date: datetime | None = Field(None, description="Last time the status of the listing changed") prc_sqft: int | None = None new_construction: bool | None = Field(None, description="Search for new construction homes") hoa_fee: int | None = Field(None, description="Search for homes where HOA fee is known and falls within specified range") diff --git a/homeharvest/core/scrapers/realtor/__init__.py b/homeharvest/core/scrapers/realtor/__init__.py index 19f2040..02f3958 100644 --- a/homeharvest/core/scrapers/realtor/__init__.py +++ b/homeharvest/core/scrapers/realtor/__init__.py @@ -574,7 +574,11 @@ class RealtorScraper(Scraper): return 'list_date' def _extract_date_from_home(self, home, date_field_name): -
