Form_for

• Most magical form helper in rails
• form_for is a ruby method into which a ruby object is passed
• form_for yields a form builder object (typically f)
• methods to create form controls are called on f, the form builder element
• when the object is passed as a form_for parameter, it creates corresponding inputs with each of the attributes
  • if i had form_for(@cat), then the form field params would look like cat[name], cat[color], etc
• in keeping with Rails convention regarding RESTful routes, there should be a resource declared for each model object (eg, resources :cats)
