Another meetup! Yay! \o/

In this free learning session, we will continue from the first event ( and discuss about the following:


• Database Migration

• Strong Params

• Flash Messages

• Controller Callbacks (before, around, after)

• Model Callbacks (before, around, after)

• Model Associations (including Polymorphism)

• Model Scopes

• Nested Attributes & Nested Querying

This event hopefully will be again a fun, casual, and efficient learning experience. These lessons meant to only guide you, and not so much as teaching you throughout the topics that will be presented, so that you will hopefully not get lost while already doing your own projects, and so that you will understand more and fast in much lesser time.

• 1 Hour Hands-on Exercise (Solving an example scenario on your own)

• As we understand that we have different motivations and schedules, you are free to leave anytime you like, especially if you are not planning on bringing your laptop to do the last part, which is the exercise :)
