#Rebuild this site

learnhowtoprogram.com is powered by a fairly simple Rails app. Rebuild it yourself.

First, work on CRUD/L functionality for lessons. A lesson has a name and some text content. Don’t worry about videos and cheat sheets. Now, we need to get the order of the lessons in. Each lesson has a number. When you click Next lesson at the bottom of the page, it goes to the lesson with the next-highest number. Here’s the spec I wrote for this method: lesson_spec.rb describe Lesson do

context '#next' do
  it 'returns the lesson with the next-highest number than the current lesson' do
    current_lesson = Lesson.create({:name => 'lesson1', :number => 1})
    next_lesson = Lesson.create({:name => 'lesson2', :number => 2})
    current_lesson.next.should eq next_lesson
  end
end

end Also, take care of the Previous lesson link.

Then, add sections: a section has many lessons. List out sections in the table of contents, along with the lessons inside them. Make the table of contents completely expanded - don’t worry about the JavaScript that lets you expand and collapse sections. When you create a lesson, provide a drop-down list of all the sections, so that the user can choose which section it’s in. (If you didn’t get to drop-downs before, do a web search for html drop-down mdn to learn how to make them in HTML.) Next, add chapters: a chapter has many sections. Make sure that the table of contents displays the lessons in the order of their number attribute. Use a default scope and the Active Record order method. Don’t know what that means? I bet you can figure it out!
