##Redis Client

redis-cli

List keys:

> keys *

Query user's API key information

> get user_<SID>

Manually remove user's API authentication token (will require the user to sign in with username and password again)

> del user_<SID>

#API Update Instructions

##Command Line

Add SID to User table. From project root directory:

bundle
bundle exec rake db:migrate

##Rails Console

Generate SID for each user record. The SID is generated (if necessary) when the User object is initialized.

> User.all.map(&:save)

##nginx To check nginx.conf

sudo /usr/sbin/nginx -t -c /etc/nginx/nginx.conf

To reload config file sudo /usr/sbin/nginx -s reload

To configure for Cross Origin Requests (CORS): /etc/nginx/nginx.conf

Below code goes in /etc/nginx/sites-available/dispatch which is then linked to /etc/nginx/sites-enabled/dispatch and is then included in /etc/nginx/nginx.conf

# From http://enable-cors.org/server_nginx.html
# Wide-open CORS config for nginx
