Relationships

Once you add a relationship, Rails will figure out routes and lets you access the related models

For example:

1. add a belongs_to relationship in the answer model. Now you can use the relations

   question.answers.create ...
   

2. Once you set up the relationships, Rails will also figure out the route

   redirect_to question
