[TYPO3-mvc] creating/deleting mm-realations between existing entities in front end?

[Uwe Michelfelder]

Hi everyone,

I managed to produce the wished behavior in the blog_example extension.
In the Post-Controller I added:

/**
 * addtag action
 *
 * @param Tx_BlogExample_Domain_Model_Tag $tag
 * @param Tx_BlogExample_Domain_Model_Post $post
 * @return string The rendered view
 */
public function addtagAction(Tx_BlogExample_Domain_Model_Post $post,
Tx_BlogExample_Domain_Model_Tag $tag)
{
    $post->addTag($tag);
    $post->setTags($post->getTags());  // is this needed?
    $this->postRepository->update($post);
    $this->flashMessages->add('Tag was added.');
    $this->redirect('show', NULL, NULL, array('post' => $post));

}

To trigger this I use this URL:
index.php?id=XXX&tx_blogexample_pi1[post]=1&tx_blogexample_pi1[tag]=1&tx_blogexample_pi1[action]=addtag&tx_blogexample_pi1[controller]=Post

This works as expexted now. :-)

In my extension however, after the
"$this->groupRepository->update($group);", nothing happens.

Is there any point in the configuration besides TCA, which tells the
Repository where to write the mm-relation.

This is my TCA config for this relation produced by the kickstarter:

[..]
'members' => array(
	'exclude' => 0,
	'label'   =>
'LLL:EXT:mmtest/Resources/Private/Language/locallang_db.xml:tx_mmtest_domain_model_group.members',
	'config'  => array(
		'type' => 'select',
		'size' => 10,
		'minitems' => 0,
		'maxitems' => 9999,
		'autoSizeMax' => 30,
		'multiple' => 1,
		'foreign_table' => 'tx_mmtest_domain_model_member',
		'MM' => 'tx_mmtest_group_member_mm',
	)
),
[..]

And the add action of my ext:

/**
 * addmember action
 * 		
 * @param Tx_Mmtest_Domain_Model_Group $group The group the member joins
 * @param Tx_Mmtest_Domain_Model_Member $member The member
 * @return string The rendered view
 */
public function addmemberAction(Tx_Mmtest_Domain_Model_Group $group,
Tx_Mmtest_Domain_Model_Member $member)
{	
	$group->addMember($member);
	 $group->setMembers($group->getMembers());				
	$this->groupRepository->update($group);	
echo "member added";
exit;
}

If someone wants to have a closer look into this, I put a zip file of
the ext here:
