Nested Sets was created by Yonder Media
Having used Component Creator quite extensively, one of the things I find myself having to make over and over again, are nested set models. For instance, Nested Sets are used in Joomla's native Category component, allowing n-tiered nesting of categories associated with other categories.
In the Table class, this requires changing it from JTable to JTableNested, and including code in the prepareTable function of the model class (an example is shown below:)
Additionally, then, this requires changes to the View classes and markup output, to correctly show entries as being nested within each other. For this, I've borrowed code from Joomla's Category Component to achieve this.
Whilst I can get this all to work, it would be a really cool feature to have this built-in to Component Creator!

protected function prepareTable($table)
{
jimport('joomla.filter.output');
$db = JFactory::getDbo();
// Specify where to insert the new node.
$parent = @$table->parent_id;
if (!empty($parent))
{
$table->setLocation($parent, 'last-child');
}
else
{
$rootId = $table->getRootId();
if ($rootId === false)
{
$db = JFactory::getDbo();
$sql = 'INSERT INTO #__yomo_ussd_article_category'
. ' SET parent_id = 0'
. ', lft = 0'
. ', rgt = 1'
. ', level = 0'
. ', title = '.$db->quote('root')
. ', alias = '.$db->quote('root')
. ', access = 1'
. ', path = '.$db->quote('')
;
$db->setQuery($sql);
$db->query();
$parent = $db->insertid();
$table->setLocation($parent, 'last-child');
}
else
{
$table->setLocation($rootId, 'last-child');
}
}
# Check that the node data is valid.
$table->check();
# Store the node in the database table.
$table->store();
}

Hi there
We like this feature though it wouldn't be easy to implement. I have added it to our roadmap poll, we will finishit soon to see what features are more interesting to all of our users. Then we will create a roadmap we will follow to improve Component Creator.
Best regards,
Andrés.

Please note that this relates only to nested sets of custom tables. You can always use the Joomla Category field and create as many nested categories you would like.
Thanks to Brian Teeman for pointing this out.
