Setup

To install dependencies:

$ cd iot_app
$ virtualenv --python python3 env
$ source env/bin/activate

Export env variables

Make sure your token is an all access token.

export INFLUX_FLASK_TOKEN=<my-token>
export INFLUX_FLASK_ORGID=<my-org-id>
export INFLUX_BUCKET=<my-bucket>

Create the sqlite database

python 
from project import db, create_app
db.create_all(app=create_app())

Run the App

To run the app:

cd iot_app
export FLASK_APP=project
export FLASK_DEBUG=1
flask run

Use the sqlite database:

Step One: Create the database if it doesn't already exist.

python 
from project import db, create_app
db.create_all(app=create_app())

Step Two: Use the database

cd project
sqlite3 db.sqlite
# To list the databases 
.databases
# To view the schema 
.schema
# To query the user table
.mode list 
select * from user;
