Question

When to choose a partial or helper or a loop in view.
Specifically, when we need a repeated structure only in a single page.
I would like to know which one is a best practice from DRY point of view and Performance point of view.

Thanks.

Answer 1

If only in a single page, as described, I would consider using a loop or partial.
– If the output is one or two lines I might just use a loop.
– If more than that a partial

If used in multiple pages I would use a helper.

Overall I prefer helpers as they feel like a more object oriented, ruby approach and they are easy and great to have tests for!
