Tanzania Locations Repo

Quick Introduction

Tanzania locations, All Regions from Tanzania, with their respective Districts wards & streets.

Very useful for easily implementing Tanzania locations in any application.

How to use

What you need before running the code.

1. Install & Start Postgresql Db Service

2. Copy files from location-files to a top level directory /posts/... this is necessary for postgresql Copy command to function as expected refer to this question.

3. Give user postgres full permissions to /posts directory with

sudo chmod -R postgres:postgres /posts

4. Create your locations database owned by postgres user

createdb --encoding utf8 --password --owner postgres DATABASE_NAME

Option --password will prompt you to enter password for the Db.

5. Use psql DATABASE_NAME to enter into the database.

6. Extract everything

• Create Tables \i tables_creation.sql

• Copy regions information to general table with \i general.sql (Don't judge the repetition)

• Extract countries \i countries.sql

• Extract all Tanzania locations \i extract.sql

7. Done!

Room for improvements

1. Locations (Region, District & Wards) need to use a different auto-incrementing ID field and not it's area code.

The area code should stay as is (in it's field), but there should be a different ID field this will help reduce mixing the IDs once we get broader than just one country.

2. This whole process can easily be automated.

3. At least we should start with general.sql as I'm really not proud of it.

4. API for this will be awesome!
