|
|
* Model Structure Data Property |
30
|
|
|
* |
31
|
|
|
* Allows for multiple complex entries to a property, which are stored |
32
|
|
|
* as a JSON string in the model's storage source. Typical use cases would be |
33
|
|
|
* {@see \Charcoal\Cms\Property\TemplateOptionsProperty template options}, |
34
|
|
|
* {@see \Charcoal\Property\MapStructureProperty geolocation coordinates}, |
35
|
|
|
* details for a log, or a list of addresses or people. |
36
|
|
|
* |
37
|
|
|
* The property's "structured_metadata" attribute allows one to build a virtual |
38
|
|
|
* model using much of the same specifications used for defining object models. |
39
|
|
|
* This allows you to constrain the kind of structure you need to store. |
40
|
|
|
* For any values that can't be bound to a model-like structure, consider using |
41
|
|
|
* {@see StructureProperty}. |
42
|
|
|
* |
43
|
|
|
* ## Examples |
44
|
|
|
* |
45
|
|
|
* **Example #1 — Address** |
46
|
|
|
* |
47
|
|
|
* With the use of the {@see \Charcoal\Admin\Widget\FormGroup\StructureFormGroup Structure Form Group}, |
48
|
|
|
* a form UI can be embedded in the object form widget. |
