Basic Rails question: manually inserting a row into a database table

Question

I'm learning Rails and it's going well so far. My biggest question at the moment is: how do I go about manually inserting a row into my database? I've got the scaffolding in place for creating rows of DataTypeOne, but I want a row for DataTypeTwo to be created when the form for DataTypeOne is submitted (and have it reference the id of DataTypeOne...but I think I can work this out on my own).

Thanks in advance.

Answer 1

You create rows in your database by creating and saving new ActiveRecord Objects (your models).

So in your controller code you could create a new row of DataTypeTwo by doing

new_record = DataTypeTwo.new
new_record.save!
