    1. COThanks for that article. You kinda have where I am going, I guess I am confused with what goes where and why. But more importantly, I am trying to figure out how the respective HTML elements interact with the Model & Controller. E.g. how does a form interact with the controller, and the model, etc. For instance, in my example - calculating the account balance in the model makes sense. But then how do I get it from the model to the view? Specifically. In the model do I initialize an instance variable and then I call that variable from the view or do I call it from the controller.

    2. COThen once it is in the controller, how do I get to it from the view to display it? If someone could just do that simple example of the bank transaction for me...then that would help me BIG time. Because I can ask specific questions about why certain things were done. I am not being lazy, I am truly trying to learn how this stuff works. I am working on a web app, and feel stuck at a particular mountain. It is difficult for me to ask for help, because it has become complicated. My problems are gaps in the fundamental understand of how it works. So I am trying to abstract that and figure it out.

    3. COOnce you calculate it in the model, you just display the method in the view. eg. <%= account.balance %> The account variable itself is populated depending on the action (eg. index) in the controller (eg. @accounts = Account.find_all) If you go through the example code in that link, it should become clear. Just replace people with accounts and age with account balance. :)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
