since I am only going to be showing that one item, do I just have (example)
/the_thing/23
or do I still go with the /the_group/1/the_thing/23
I know I need to appropriately nest and have associations for forms and using nested routes for links, but for a show page is my link to it nested or not?
i.e. should I still show it within the context of its master or just on it’s own. In this case the resource cannot be updated without the nesting i.e. on it’s own.
Will a main intent be to show links back to the group?
This question is ONLY about the show page.
This is just a matter of choice, you can even create both routes depending on the context.
You should just ask yourself if it makes more sense for the user to see one url or the other: it’s sheer user experience here.
