Join Kevin Skoglund for an in-depth discussion in this video Generating a model, part of Ruby on Rails 4 Essential Training.
…In this movie, we'll look at how you generate a model.…I realize we already generated several models…in the last chapter while working with migrations.…But at the time, we were focused on migrations.…Now we need to take a closer look at…the models because there's some important points to understand.…To review, when we generate a model, we go to…the command line and from the root of the Rails application.…You type rails, generate, model.…And then the name of the model that you…want to create as a singular name written in camel case.…So for example, rails generate model Subject.…
That would then generate a file in db/migrate that…would be our migration, and it would call it create_subjects.…Plural, there would be a class name of that migration called create subjects.…Again, also plural.…And it would inherit from ActiveRecord migration.…It would populate it with code for creating…the table subjects and dropping the table subjects.…Or if it gave us that change method, it might only have the create table subjects.…
