Ruby on Rails: How to add parameter to database in existing model

Question

I built a model using rails g model name:string, description:text, price:float, and finished my project, but now want to add more parameters to the model. Instead of starting over, how can I add more parameters? Is there a method to do so within the rails console?

Answer 1

rails generate migration AddColumnToTable column:datatype

so if you wanted to add a name column to a people table it might look like:

rails generate migration AddNameToPeople name:string

then run rake db:migrate
