Ruby/Rails - Models Named with Two Words (Naming Convention Issues)

Question

This is really a question about naming conventions.

I have a model called PromotedEvents

The file is called promoted_events.rb

I created the table wi

Answer 1

If it helps, I always think of it like this:

The model name is singular because it represents a single, specific thing. So, PromotedEvent is a specific promoted event that has a name, date, etc.

The table name on the other hand is plural. This is because the table stores a collection of these singular items. So, promoted_events.

In rails, filenames are mostly a matter of convention since ruby has pretty lax rules in this regard, but generally it's class_name.rb. This page might help you get a better overview of what conventions are used where and what is specific to Ruby versus Rails.

Answer 2

Your class should be singlular.

Name it PromotedEvent in the file promoted_event.rb

a = PromotedEvent.new

Answer 3

If you are an extreme rails n00b like me, then you will want to remember to create a class definition for your newly created table and place it in app/models.

It would go like

class LargeCat < ActiveRecord::Base
    belongs_to :zoo
end

Answer 4

Model names are singular and camel case like so pe = PromotedEvent.new()

the file should be promoted_event.rb

Controllers are plural

PromotedEventsController

constants are ALL_CAPS

locals are separated_by_underscores_and_lowercase

table names are plural 'SELECT * FROM promoted_events`
