Hi Austin,
As Geert said, welcome to the mailing list! He's right about that a lot
of people don't post -- it took me a while to work up to it for some of
the same reasons you list: just feeling dumb or being intimidated. :)
I'll just address how to pull info out of the ContentStore after it has
been entered via CRUD.
First, a note about how CRUD works with RIFE base: All of the
programmatic access for database tables and record access (creation,
reading, updating, deleting) exist in RIFE base. What CRUD provides is
a sort of instant setup tool for creating the database tables to manage
data for the bean and its content related properties, as well a GUI for
Creating, Reading, Updating, and Deletion. It (CRUD) does a little more
than that, but that's the main conceptual gist.
So, while you may use CRUD for record administration or getting some
data into the system for prototyping, you will probably (as you
discovered) want to create some sort of custom display rather than
CRUD's stock List element and template.
Ok, it sounds like you managed to get the CRUD interface set up, and
enter some records. Now, you want to display them via something other
than CRUD's default List element. This is done by using the RIFE base
ContentQueryManager methods:
========
Datasource ds =
Datasources.getRepInstance().getDatasource("datasource");
ContentQueryManager<NewsItem> mgr = new
ContentQueryManager<NewsItem>(ds, NewsItem.class);
// Retrieve all of the NewsItems
List<NewsItem> items = mgr.restore();
// If NewsItems had a boolean 'active' property, you could restrict
your results to only the 'active' NewsItems like so
//List<NewsItem> items =
mgr.restore(mgr.getRestoreQuery().where("active","=",true));
// We'll just log them for now as an exercise so we can see them.
Logger log = Logger.getLogger(this.getClass().getName());
for( NewsItem item : items ) {
log.info("NewsItem id=["+item.getId()+"],
title=["+item.getTitle()+"]");
}
========
Once you have the records, you can populate a template with them, etc.
I recommend for starters just logging them so you can see that you are
retrieving them, then moving on to working with templates.
The "content management framework" cookbook page will be helpful if you
note that CRUD takes care of installing the database tables for the
content query management system as well as the table for the bean. CRUD
also provides a default add element (along with edit, list, and delete),
so the part you'll want to focus on is the ViewNews element.

Feel free to ask for clarification if you get stuck. Since RIFE is a
fairly complete framework on its own, there are a lot of parts to it and
it takes a while to digest. :)
