Add updated_since parameter (accepts datetime object or ISO string) - Add updated_in_past_hours parameter (accepts int or timedelta) - Implement _apply_last_update_date_filter() method for client-side filtering - Add mutual exclusion validation for updated_* parameters Part B: Improve time interface DX - Accept datetime/timedelta objects for datetime_from, datetime_to - Accept timedelta objects for past_hours, past_days - Add type conversion helper functions in utils.py - Improve validation error messages with specific examples - Update validate_datetime to accept datetime objects Helper functions added: - convert_to_datetime_string() - Converts datetime objects to ISO strings - extract_timedelta_hours() - Extracts hours from timedelta objects - extract_timedelta_days() - Extracts days from timedelta objects - validate_last_update_filters() - Validates last_update_date parameters All changes are backward compatible - existing string/int parameters still work. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- homeharvest/__init__.py | 51 ++++-- homeharvest/core/scrapers/__init__.py | 8 + homeharvest/core/scrapers/realtor/__init__.py | 50 +++++- homeharvest/utils.py | 149 ++++++++++++++++-- 4 files changed, 237 insertions(+), 21 deletions(-) diff --git a/homeharvest/__init__.py b/homeharvest/__init__.py index b0599be..45721c6 100644 --- a/homeharvest/__init__.py +++ b/homeharvest/__init__.py @@ -1,7 +1,12 @@ import warnings import pandas as pd +from datetime import datetime, timedelta from .core.scrapers import ScraperInput -from .utils import process_result, ordered_properties, validate_input, validate_dates, validate_limit, validate_offset, validate_datetime, validate_filters, validate_sort +from .utils import ( + process_result, ordered_properties, validate_input, validate_dates, validate_limit, + validate_offset, validate_datetime, validate_filters, validate_sort, validate_last_update_filters, + convert_to_datetime_string, extract_timedelta_hours, extract_timedelta_days +) from .core.scrapers.realtor import RealtorScraper from .core.scrapers.models import ListingType, SearchPropertyType, ReturnType, Property from typing import Union, Optional, List @@ -13,7 +18,7 @@ def scrape_property( property_type: Optional[List[str]] = None, radius: float = None, mls_only: bool = False, -

Changes: - Remove datetime_from and datetime_to parameters (confusing to have both) - Update date_from/date_to to accept multiple formats: - Date strings: "2025-01-20" (day precision) - Datetime strings: "2025-01-20T14:30:00" (hour precision) - date objects: date(2025, 1, 20) (day precision) - datetime objects: datetime(2025, 1, 20, 9, 0) (hour precision) - Add detect_precision_and_convert() helper to automatically detect precision - Add date_from_precision and date_to_precision fields to track precision level - Update filtering logic to use precision fields instead of separate parameters - Update README to remove datetime_from/datetime_to examples - Update validation to accept ISO datetime strings Benefits: - Single, intuitive parameter name (date_from/date_to) - Automatic precision detection based on input format - Reduced API surface area and cognitive load - More Pythonic - accept multiple input types All changes are backward compatible for existing date_from/date_to string usage. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- README.md | 23 +++---- homeharvest/__init__.py | 39 +++++++----- homeharvest/core/scrapers/__init__.py | 8 +-- homeharvest/core/scrapers/realtor/__init__.py | 28 +++++---- homeharvest/utils.py | 63 ++++++++++++++++--- 5 files changed, 108 insertions(+), 53 deletions(-) diff --git a/README.md b/README.md index 63d284e..049e9db 100644 --- a/README.md +++ b/README.md @@ -83,8 +83,8 @@ properties = scrape_property( properties = scrape_property( location="Dallas, TX", listing_type="for_sale", - datetime_from="2025-01-20T09:00:00", - datetime_to="2025-01-20T17:00:00" + date_from="2025-01-20T09:00:00", # Hour precision automatically detected + date_to="2025-01-20T17:00:00" ) ``` @@ -230,8 +230,8 @@ properties = scrape_property( properties = scrape_property( location="Phoenix, AZ", listing_type="for_sale", - datetime_from=datetime.now() - timedelta(days=7), - datetime_to=datetime.now(), + date_from=datetime.now() - timedelta(days=7), # datetime object - hour precision + date_to=datetime.now(), limit=100 ) ``` @@ -313,13 +313,14 @@ Optional │ ├── date_from, date_to (string): Start and end dates to filter properties listed or sold, both dates are required. | (use this to get properties in chunks as there's a 10k result limit) -│ Format for both must be "YYYY-MM-DD". -│ Example: "2023-05-01", "2023-05-15" (fetches properties listed/sold between these dates) -│ -├── datetime_from, datetime_to (string): ISO 8601 datetime strings for hour-precise filtering.
