Example building rest services in python and interacting with DynamoDB

Pip & sqlite

sudo apt-get install pip    
sudo apt-get install sqlite3 libsqlite3-dev

Install Python Packages

flask, boto, dynamodb-mapper, urllib, httplib, json

Run these scripts to see the example code work

Create a mock dynamo db; NOTE: you'll have to ctrl-z to break this script due to create_table bug

python src/main/db_create.py

Start rests services (in separate terminal)

python src/main/rest_test.py

Post data through rest service to mock dynamo db

python src/main/post_rest_test.py 1 'hello world'

Read back the data from mock dynamo db through rest service

python src/main/get_rest_test.py 1

Clean up the mock dynamodb

rm /tmp/pyrest.sqlite
