When to use render vs redirect_to when handling error validations

Answer 1

First, these are not compiler error - its run-time errors.
Second, you should either check your data in the controller to make sure its being served properly for rendering OR do some conditional blocks in the view in order to cope with this different data structures.

Lastly, redirect_to is just a technique of moving the user around, it could be used here but you still need to handle those errors, even in the redirected-to page...
