Question

Let’s say that you have a resource that is created and displayed entirely within the view of another resource (eg. comments or tags). Should you still make it it’s own resource, or would it be a better idea to make it a nested resource? Also, should you make use of virtual attributes?

I know this question is general, but I’m not looking for a specific answer, just a general explanation of when each technique is preferred.

Answer 1

Some general thoughts:

• Nesting and independent resources are not necessarily mutually exclusive.
• “created and displayed entirely within the view of another resource” is a strong statement that can end up not being true. For example, tags: do you ever want a list of all articles with a certain tag. that would not make sense nested.
• Nesting below the second or third level will begin to be more trouble then its worth. Some will say that even the first nesting is more trouble then its worth.
• For an app that has a single dominate resource the cost of adding other independent resources is proportionally higher. Small apps can get away with complexities that large apps cannot.
• If you don’t have a good feel yet write a few resources each way. Answers will at best be justifies opinions it is probably best to develop you own through experience.
