Overview

Please write the overview about this PR.

What's in this PR:

0. Authentication

• Even though authentication, I've configured DoorKeeper to enable sign-in/sign-out at:
  • /oauth/token
  • /oauth/revoke

The authentication will be needed in some actions, like Rating, List Recipes...

• I've also added seed data with 1 web application in oauth_applications and 2 users;
• Parameters to used for signing in: beside email and password, one would also need:
  • client_id, client_secrete, which are uid, secrete in oauth_applications
  • grant_type = 'password'

1. Search recipes: /api/recipes has been updated to have filter/search feature

Note about filter by time range:

• To efficiently query by time range, I assumed the data saved into recipes#time field is in format: hh:mm:ss
• A rough implementation of Recipe#time_string=(st) and Recipe#time_string to set/get string format of time field
• time param can be a little flexible in format, e.g.:
  • 1 hour 30 mins
  • 1hour 30mins
  • 2 hours
  • 45mins
  • ...

2. Weight converter: GET /api/converters/convert

• I'm not sure I understand the requirement correctly, but this converter is implemented as fixed, regardless ingredient.

• It requires 3 parameters:

  • from_unit
  • from_amount
  • to_unit
    e.g /api/converters/convert?from_unit=cup&to_unit=gram&from_amount=5

• In my opinion, converter should be dependent on ingredient. (A cup of water and a cup of sugar will be corresponding to different number of grams

BTW, I also think an ingredient should have a name

3. Rating: APIs for this feature require authentication (Bear)

• APIs are provided to allow a user to
  • rate/update rating (from 1-5) on a recipe
  • view rating list of a particular recipe
