…[MUSIC]…Here's my solution to the challenge assignment.…This code is included in the exercise files.…The first objective was to generate three models.…So I did that, rails, generate model subject,…rails generate model page, and rails generate model section.…Notice that I used camel case, and I made them singular.…That's what we want to use for our models.…And it created a model here, at model subject, one…for page, and one for section, and three corresponding migrations.…
Next, we needed to write the migrations themselves.…For create subjects, it gave me the template for create subject,…and I just needed to fill it in with my definitions.…So, I've got name, which is a string, position,…which is an integer, and visible, which is a Boolean.…I also went ahead and added a default option for Boolean.…This is a good idea, especially if a Boolean is going to be true or…false, go ahead and pick one of them to be the default in the database.…Would you rather it default to true?…Or would you rather it default to false?…
