dedupe-variable-datetime

2.0.0 verified Fri May 01 auth: no python

DateTime variable type extension for the dedupe library, used for fuzzy matching datetime fields. Current version 2.0.0. Updated irregularly; last release 2023.

pip install dedupe-variable-datetime

Common errors

error ModuleNotFoundError: No module named 'dedupe.variables.datetime' ↓

cause Attempting to import from wrong path or package not installed with matching version.

fix

Install dedupe-variable-datetime: pip install dedupe-variable-datetime, then import using from dedupe.variables.datetime import DateTimeType.

error TypeError: __init__() got an unexpected keyword argument 'field' ↓

cause Using incorrect constructor signature; DateTimeType may not accept field as a direct argument.

fix

Define fields in the Datamodel dictionary with 'type': 'DateTime', not by instantiating DateTimeType directly.

Warnings

gotcha DateTimeType expects date strings in ISO 8601 format (YYYY-MM-DD) or similar parseable formats; inconsistent formats may cause errors. ↓

fix Preprocess datetime fields to a consistent format before passing to dedupe.

deprecated The package may rely on old-style dedupe API; check compatibility with dedupe >=2.0. ↓

fix Use dedupe v2.x and ensure dedupe-variable-datetime is updated to 2.0.0.

gotcha Time zones are not handled; naive datetimes assumed. Potential mismatch when comparing across time zones. ↓

fix Convert all datetimes to UTC or naive before comparison.

Imports

DateTimeType
```
from dedupe.variables.datetime import DateTimeType
```
Direct import from the package's submodule

Quickstart

Minimal example to verify installation and import of DateTimeType.

from dedupe import Datamodel
from dedupe.variables.datetime import DateTimeType

# Define fields including a datetime field
fields = [
    {'field': 'date', 'type': 'DateTime'},
    {'field': 'name', 'type': 'String'}
]

datamodel = Datamodel(fields)
print('Datetime variable loaded successfully')
