/**

|
|
* ComplexTableField with a radio button column, designed to edit a has_one join.
|
2010-10-15 05:55:22 +02:00
|
|
|
*
|
|
|
|
|
* This [RelationTable](RelationTable) allows you to show a **1-to-1** or **1-to-many** relation with a group of DataObjects as a (readonly) tabular list (similiar to [ComplexTableField](ComplexTableField)). Its most useful when you want to manage the relationship itself thanks the **radio buttons** present on each line of the table.
|
|
|
|
|
*
|
|
|
|
|
* Moreover, you have the possibility to uncheck a radio button in order to make the relation as null.
|
|
|
|
|
*
|
|
|
|
|
* <b>Usage</b>
|
|
|
|
|
*
|
|
|
|
|
* <code>
|
|
|
|
|
* $tablefield = new HasOneComplexTableField(
|
|
|
|
|
* $this,
|
|
|
|
|
* 'MyOnlyFruit',
|
|
|
|
|
* 'Fruit',
|
|
|
|
|
* array(
|
|
|
|
|
* 'Name' => 'Name',
|
|
|
|
|
* 'Color' => 'Color'
|
|
|
|
|
* ),
|
|
|
|
|
* 'getCMSFields_forPopup'
|
|
|
|
|
* );
|
|
|
|
|
* </code>
|
|
|
|
|
*
|
|
|
|
|
* **Notice** : You still have different ways to customize the popup window as in the parent-class [ComplexTableField](ComplexTableField).
|
|
|
|
|
*
|
|
|
|
|
* This field is made to manage a **has_one** relation. In the SilverStripe relation between DataObjects, you can use this relation for **1-to-1** and **1-to-many** relations.
|
|
|
|
|
* By default, a HasOneComplexTableField manages a **1-to-many** relation. If you want to specify that the relation that you manage is a **1-to-1** relation, add this code :
|
|
|
|
|
*
|
|
|
|
|
* <code>
|
|
|
|
|
* $tablefield->setOneToOne();
|
|
|
|
|
* </code>
|
