platemate

PlateMate: crowdsourcing nutritional analyses from food photographs

Setup

Install requirements

sudo apt-get install libjpeg-dev
pip install -r requirements.txt

This should install:

• Django 1.2.5
• Pillow (latest)
• Boto (latest)
• httpagentparser (latest)
• oauth latest

Modify Local Settings

In the platemate directory modify local_settings.example.py to your paths and rename to local_settings.py. In the platemate directory, add your Amazon Mechanical Turk keys in amt_keys.example.py and save it as amt_keys.py

Create Database Tables

From the platemate directory, run: python manage.py syncdb --noinput

Add an admin user

python manage.py createsuperuser
//TODO add the user to initial data fixutre (or is there one?)

Run the project

python manage.py runserver 0.0.0.0:8000

or ./run.sh

Create HITs on Amazon MTurk sandbox

python experiment.py BATCH_NAME sandbox

where BATCH_NAME is a subdirectory under static/uploaded. This is hardcoded and specifying any other path will break things.

Issues

Module no found

Cause: Likely an import statement in the module is failing because of a missing library. Fix: Try each import in the module individually.

Database Locked

It seems that when both the runserver and the experiment scripts are running, there is a race condition on the database that would crash one script if the other is accessing the DB.

Accessing the database through adminer on iis-dev:

http://adminer.iis-dev.seas.harvard.edu/adminer/

Deleting all hits from mturk AND resetting the database

python cleanup.py flush
