Authorization and Architecture

For this short assignment, you will simple use a memcache server to cache requests

A. Memcache

Please refer to work you did for "Authorization and Architecture" assignment, part B

Create cache on Memcachier for your credit card service
- Make a development cache
- Make another production cache
Store Memcachier credentials (server, username, password) in config_env.rb

Modify the index route for your API
- (From previous assignment) Recall from an earlier assignment that you made a GET '/api/v1/credit_card?user_id=#' route
- Make sure this route checks the user_id is the same as the one in the JWT authentication token it receives
- This time, make sure this route only returns the last 4 digits of credit cards (not full credit card)
Memcache on index route of API service
- Whenver the API's index route is called, store the results on Memcachier
- Use user_id as the memcache key
- Store JSON of user's credit cards (last 4 digits only) on Memcachier
- Return index from API as normal
Memcache on creation of new credit card
- Whenever the API's create new card route is called, store new index for user on Memcachier
- Try to reuse a method to create and store user's index

Move your Web App's index view to the home page
- (From previous assignment) Make sure you have a view to show all credit cards for a user
- Move the contents of this view to the home page
- Logged in users should see all their credit cards on main home page
Check Memcache for index view
- Before calling the API for user's index of credit cards, check Memcachier service for results with user_id key
Does your home page (index) seem to load a bit faster now?
