App to display Twin Cities Landlord Information |
|
|
This is a minimal Django app, without a database, that is deployed to https://tc-landlords.azurewebsites.net/
Everything interesting is in the licenses module.
The file licenses-raw.csv is a direct export of the licence data from this shape file https://opendata.minneapolismn.gov/datasets/active-rental-licenses
Then transform.py was used locally to clean the data, create columns for the owners phone, email, name and address in a standard format. These columns are called xPhone, xEmail, xName and xAddress. Once this was done, the Union-Find algorithm was used to efficiently group records that matched on any of these fields. The reuslting data are written back to
clean_grouped_rental_licenses.csv, which is deployed as part of the Django app.
To generate a fresh version of clean_grouped_rental_licenses.csv, run
python clean_rental_licenses
The is a very simple Django app that allows you to find all properties that are owned by the same landlord as a given property.
