抢答环节 - constructor method in ruby: def initialize - model inherit from applicationRecord - eigenclass: object first look here for methods, then go up the object inheritance chain - regex question 会考 让我们interpret 不让我们写，lab5 - %w - self = current object - api 会考 - concept + technical都考。。。。 - always order by - HTTP verbs - regex shortcut \w = any letter or digit - process logic -- controller - controller会考 - SQL clause for patch: update - setup -- test --prior to each test - size of a network increases, network's value increases exponentially. - public api - types of api - what are partials? concepts+code .... - getter and setter method created by (attr_accessor) method - authenticate -- provided by has_secure_password - local variables in ruby begin with lower-case letter. - superclass for Float: numeric - add modules to eigenclass of the object and is often used to add class method to a give class -- extend method - include: add instance method - extends: add class method - search tool: forgiving, fast, accurate - end of a line or string - $ or \z - get http verb: show index new edit - authenticate_or_request_with_http_basic - allow user to authenticate with a base64 encoded string of username:password - Lab / PATS / code already written / phase 3 / class exercise

• basic, document api -- swagger doc (why?), customize api (why? to prevent users from a lot of load, no mega call to a lot things)
• why serializers? to decrease number of calls, nice to get all information in one call
• why filters in api?
