Rails apps are built on an MVC (Model, View, Controller) architecture. In the last few articles of this miniseries, we've focused exclusively on the model component of MVC, building tables in the database, building corresponding models in Rails, and importing the data through Rails models into the database. Now that we have a bunch of monster taming data in the database, we want to be able to look at that data and browse through it in a simple way. We want a view of that data. In order to get that view, we'll need to request data from the model and make it available to the view for display, and that is done through the controller. The view and controller are tightly coupled, so that we can't have a view without the controller to handle the data. We also need to be able to navigate to the view in a browser, which means we'll need to briefly cover routes as well. Since that's quite a bit of stuff to cover, we'll start with the simpler monster material model as a vehicle for explanation.
