Why is MM_opposite_field working with inline?
0%
Description
Hi,
I have this situation:
A bidirectional MM relation
events <-> projects
In event I use select:
'projects' => array(
...
'config' => array(
'type' => 'select',
'foreign_table' => 'tx_extendeventmgmt_domain_model_projects',
...
In project is use inline:
'events' => array(
'exclude' => 1,
'label' => 'LLL:EXT:eventmgmt/Resources/Private/Language/locallang_db.xlf:tx_eventmgmt_domain_model_event.events',
'config' => array(
'type' => 'inline',
'foreign_table' => 'tx_eventmgmt_domain_model_event',
'MM' => 'tx_extendeventmgmt_event_projects_mm',
'MM_opposite_field' => 'projects',
'appearance' => array(
'collapseAll' => 0,
'levelLinksPosition' => 'top',
'collapseAll' => TRUE,
'showPossibleLocalizationRecords' => 1,
),
'behaviour' => array(
'localizationMode' => 'select',
'localizeChildrenAtParentLocalization' => TRUE,
),
'size' => 10,
'autoSizeMax' => 30,
'maxitems' => 9999,
'multiple' => 1,
),
),
When I select a project on the event side the event should also be shown on the project side.
When I add 'MM_opposite_field' => 'projects' it works, if I don't it doesn't.
As far as I know MM_opposite_field is just for "select", not for "inline" and the documentation (http://docs.typo3.org/typo3cms/TCAReference/Reference/Columns/Inline/Index.html) says nothing about MM_opposite_field.

I didn't test myself, so please bear with me.
From reading your report, I consider this a documentation issue, right?
So mm_opposite needs to be set in order for the feature to work.
Did I get this right so far?
Updated by Eike Starkmann over 9 years ago
Yeah this is right.
If this feature is meant to work together with inline then yes it is a documentation issue.
But I'm not sure if it is really meant to work with inline.
Is there a way of building bidirectional MM relation without mm_opposite_field?

As far as I can see from the examples we have in the styleguide extension, there are more valid fields for inline MM relations than documented. Example from styleguide:
'parents' => [
'exclude' => 1,
'label' => 'parents',
'config' => [
'type' => 'inline',
'foreign_table' => 'tx_styleguide_inline_mm_child',
'MM' => 'tx_styleguide_inline_mm_child_childchild_rel',
'MM_hasUidField' => true,
'MM_opposite_field' => 'inline_2',
'maxitems' => 10,
'appearance' => [
'showSynchronizationLink' => 1,
'showAllLocalizationLink' => 1,
'showPossibleLocalizationRecords' => 1,
'showRemovedLocalizationRecords' => 1,
],
],
],
Docs should be adjusted.
