/**
|
|
* Special ComplexTableField for editing a many_many relation.
|
|
*
|
|
* This field allows you to show a **many-to-many** relation with a group of
|
|
* DataObjects as a (readonly) tabular list (similiar to {@link ComplexTableField}).
|
|
* Its most useful when you want to manage the relationship itself
|
|
* thanks to the check boxes present on each line of the table.
|
|
*
|
|
* See {@link ComplexTableField} for more documentation on the base-class.
|
|
* See {@link HasManyComplexTableField} for more documentation on the relation table base-class.
|
|
*
|
|
* Note: This class relies on the fact that both sides of the relation have database tables.
|
|
* If you are only creating a class as a logical extension (that is, it doesn't have any database fields),
|
|
* then you will need to create a dummy static $db array because SilverStripe won't create a database
|
|
* table unless needed.
|
|
*
|
|
* <b>Usage</b>
|
|
*
|
|
* <code>
|
|
* $tablefield = new ManyManyComplexTableField(
|
|
* $this,
|
|
* 'MyFruits',
|
|
* 'Fruit',
|
|
* array(
|
|
* 'Name' => 'Name',
|
|
* 'Color' => 'Color'
|
|
* ),
|
|
* 'getCMSFields_forPopup'
|
|
* );
|
|
* </code>
