# ModelAdmin
|
|
|
|
## Introduction
|
|
|
|
*Replaces GenericDataAdmin in Silverstripe 2.3*
|
|
|
|
The ModelAdmin provides a simple way to utilize the SilverStripe CMS UI with your own custom data models. The
|
|
ModelAdmin uses the `[api:DataObject]`'s Scaffolding to create the search fields, forms, and displayed data within the
|
|
CMS.
|
|
|
|
In order to customize the ModelAdmin CMS interface you will need to understand how `[api:DataObject]` works.
|
|
|
|
## Requirements
|
|
|
|
*Requires Silverstripe 2.3*
|
|
|
|
## Usage
|
|
|
|
### Step 1
|
|
Extend ModelAdmin with a custom class for your admin area, and edit the `$managed_models` property with the list of
|
|
data objects you want to scaffold an interface for:
|
|
|
|
:::php
|
|
class MyCatalogAdmin extends ModelAdmin {
|
|
|
|
public static $managed_models = array( //since 2.3.2
|
|
'Product',
|
|
'Category'
|
|
);
|
|
|
|
static $url_segment = 'products'; // will be linked as /admin/products
|
|
static $menu_title = 'My Product Admin';
|
|
|
|
}
|
|
|
|
|
|
To add the ModelAdmin to your CMS menu, you simply need to define a couple of statics on your ModelAdmin subclass. See
|
|
`[api:LeftAndMain]` on how to make your menu title translatable.
|
|
|
|
|
|
### Step 2
|
|
Add a `$searchable_fields` (See `[api:ModelAdmin::$searchable_fields]`) property to your data
|
|
models, to define the fields and filters for the search interface:
|
|
|
|
Datamodel `Product`:
|
|
|
|
:::php
|
|
class Product extends DataObject {
|
|
|
|
static $db = array(
|
|
'Name' => 'Varchar',
|
|
'ProductCode' => 'Varchar',
|
|
'Description' => 'Text',
|
|
'Price' => 'Currency'
|
|
);
|
|
|
|
static $has_one = array(
|
|
'Category' => 'Category'
|
|
);
|
|
|
|
static $searchable_fields = array(
|
|
'Name',
|
|
'ProductCode'
|
|
);
|
|
|
|
}
|
|
|
|
|
|
Datamodel `Category`:
|
|
|
|
:::php
|
|
<?php
|
|
class Category extends DataObject {
|
|
static $db = array(
|
|
'Title' => 'Text'
|
|
);
|
|
}
|
|
?>
|
|
|
|
|
|
### Step 3
|
|
You can now log in to the main CMS admin and manage your data objects, with no extra implementation required.
|
|
|
|
|
|
|
|
|
|
|
|
### Note about has_one
|
|
|
|
Scaffolding **has_one** relationships in your ModelAdmin relies on a column in the related model to be named **Title**
|
|
or **Name** of a string type (varchar, char, etc). These will be pulled in to the dropdown when creating a new object.
|
|
|
|
If you are seeing a list of ID#s when creating new objects, ensure you have one of those two in the related model.
|
|
|
|
## Searchable Fields
|
|
|
|
You can customize the fields which are searchable for each managed DataObject class, as well as the ways in which the
|
|
fields are searched (e.g. "partial match", "fulltext", etc.) using `$searchable_fields`.
|
|
|
|
* See `[api:DataObject]`
|
|
|
|
|
|
|
|
## Summary Fields
|
|
|
|
Summary Fields are the columns which are shown in the `[api:TableListField]` when viewing DataObjects. These can be
|
|
customized for each DataObject's search results using `$summary_fields`.
|
|
|
|
* See `[api:DataObject]`
