I am just starting my first ruby project. I followed tutorial and built a blog. I thought next i would add a commenting system to extend the project, I just added has_many :comments to my post model. In the tutorial after we built the model we raked the database. Im not entirely sure what it does, but it seems fairly important. Is this something at I will need to do again and any time i update a model? I am using the gem ‘sqlite3’
thanks
Every time you create a new model (database table) you got to run the migration, which creates the table in the database. Whenever you make any change to the db, you got to run migrations so as to make sure your db is in sync with your latest changes.
