Energy usage web app

Rails
1

Hi all, need some advise.

I’m still new on RoR, I’m about to create a Web app that monitors energy
consumption such as, electricity, water and waste.

User can input the datas manually and later on they can view the usages
in a day, week, year and by selecting particular dates.

Where should I start and what part should I start. I’m still stuck on
designing the database. But I already play around with chartkick a
little bit.

Thx

I usually start by working out what are the key data objects that need
to be represented in the database, and the associations between them
(has_many, belongs_to etc). Possibly User, MeterReading for example,
then build the system up from there. Make sure you write your tests
as you go so that when you refactor things (as you surely will) the
tests allow confidence that the refactoring is ok.

This document (getting started RoR) has many answers to your possible
questions. It is best to start
with Testing Rails Applications — Ruby on Rails Guides and railscasts.com - a
little outdated but has many great examples there.
Start with those, rest will follow :wink:
