So I come to the part where I do
ruby script/generate model Page
part of the book. I realize that much has changed in 3 years in the Ruby on Rails world. I do what any newb does when they’re stuck, I turn to search. The command is
rails generate model Page
and whah-lah. Output appears on the terminal screen that something has automagically taken place. It can make you giddy. I have to laugh at this stuff, pros will look at this reaction and laugh. I think it’s simply awesome.
I move on and update the project/db/migrate/version_create_pages.rb file so that it has some info to insert as a record into my newly created table.
Page.create(:title => "Find A Gamer Home", :permalink => "welcome-page", :body => "Welcome to Find A Gamer")
in the self.up method. Save.
Shoot over to command line…
Thinks for a second and nothing seems to happen. The command line has let me down. I try again. Same result. Huh. You’d think it would change right? Just typing in the same command nothing happens, same result, strange.
Turn to search. Find some info on version numbers. Check database table, nothing new. I use
rails generate migration
don’t do that. It creates a blank migration.rb type file. Database does nothing. I end up deleting file.
I then try
rake db:migrate VERSION=<insert version number>
from <version number>_create_pages.rb file. and….BAM! some promising output appears on screen saying
The above syntax is not verbatim, but you get the idea. Oh, the create_table part, yeah, I ended up dropping my database table with a command I shouldn’t have used. Good times.
Now, I thought rails db:migrate would do the trick without a version number, but I’ll go this route for now. Go with what works, right?
