Managing Hierarchical Data

Hello,

I am in the process of trying to date hierarchical data in a MySQL
database and convert it into a treeview view JS scripting. As a beginner
to ROR there are still many unknown things to me, and handling this sort
of data is one of them. My question is this: Is there any built in
functionality for handling hierarchical data (via a MySQL DB) in
Rails/Ruby? If there is can someone please explain it or link to
documentation on it? That would be of great help, thanks.

Do any of those help? You could also simply setup your models
appropriately
and use some type of parent_id as a foreign key.

Somewhat, though not really. Essentially what I am trying to build is a
hierarchical subject list, like how you might navigate a site. For
instance you select “Toys” and it drops down to list the sub-groups
“electronic” and “mobile”. I was simply wondering if there were any
tools to help organize this data so that creating such a list would be
much more simpler as I lack the skills to hard code my own version into
the model.
