/**
|
|
* Provides a tabuar list in your form with view, edit and add links to edit records
|
|
* with a "has-one"-relationship. Detail-views are shown in a greybox-iframe.
|
|
* Features pagination in the overview as well as the detail-views.
|
|
*
|
|
* CAUTION: You need to make sure that the original form-call to the main controller (e.g. EditForm())
|
|
* returns a form which includes this field even if no data is loaded,
|
|
* to provide a "starting point" for action_callfieldmethod and ReferencedField.
|
|
*
|
|
* All URL data sent to and from ComplexTableField is encapsulated in $_REQUEST['ctf']
|
|
* to avoid side-effects with the main controller.
|
|
*
|
|
* Example-URL for a "DetailForm"-call explained:
|
|
* "/admin/family/?executeForm=EditForm&action_callfieldmethod&fieldName=Individual&childID=7&methodName=edit"
|
|
* - executeForm Name of the form on the main rendering page (e.g. "FamilyAdmin")
|
|
* - action_callfieldmethod Trigger to call a method of a single field in "EditForm" instead of rendering the whole thing
|
|
* - fieldName Name of the targeted formField
|
|
* - methodName Method on the formfield (e.g. "ComplexTableField")
|
|
* - childID Identifier of the database-record (the targeted table is determined by the $sourceClass parameter)
|
|
*
|
|
* TODO Find a less fragile solution for accessing this field through the main controller and ReferencedField, e.g.
|
|
* build a seperate CTF-instance (doesn't necessarly have to be connected to the original by ReferencedField)
|
|
* TODO Control width/height of popup by constructor (hardcoded at the moment)
|
|
* TODO Integrate search from MemberTableField.php
|
|
* TODO Less performance-hungry implementation of detail-view paging (don't return all items on a single view)
|
|
* TODO Use automatic has-many and many-many functions to return a ComponentSet rather than building the join manually
