## Overview
This class gives your application a RESTful API. All you have to do is set the `api_access` configuration option to `true`
on the appropriate DataObjects. You will need to ensure that all of your data manipulation and security is defined in
2012-06-04 10:14:02 +02:00
your model layer (ie, the DataObject classes) and not in your Controllers. This is the recommended design for SilverStripe
applications.
## Requirements
* SilverStripe 4.0 or higher
2012-06-04 10:14:02 +02:00
For a SilverStripe 3.x compatible version of this module, please see the [1.0 branch, or 1.x release line](https://github.com/silverstripe/silverstripe-restfulserver/tree/1.0#readme).

## Configuration
2012-06-04 10:14:02 +02:00
Example DataObject with simple API access, giving full access to all object properties and relations,
2012-06-04 10:14:02 +02:00
unless explicitly controlled through model permissions.
```php
namespace Vendor\Project;
use SilverStripe\ORM\DataObject;
class Article extends DataObject {
private static $db = [
'Title'=>'Text',
'Published'=>'Boolean'
];
private static $api_access = true;
}
```
Example DataObject with advanced API access, limiting viewing and editing to Title attribute only:
```php
namespace Vendor\Project;
use SilverStripe\ORM\DataObject;
class Article extends DataObject {
2012-06-04 10:14:02 +02:00
private static $db = [
'Title'=>'Text',
'Published'=>'Boolean'
];
2012-06-04 10:14:02 +02:00
private static $api_access = [
'view' => ['Title'],
'edit' => ['Title']
];
}
```

## Supported operations
- `GET /api/v1/(ClassName)/(ID)` - gets a database record
- `GET /api/v1/(ClassName)/(ID)/(Relation)` - get all of the records linked to this database record by the given reatlion
- `GET /api/v1/(ClassName)?(Field)=(Val)&(Field)=(Val)` - searches for matching database records
- `POST /api/v1/(ClassName)` - create a new database record
- `PUT /api/v1/(ClassName)/(ID)` - updates a database record
- `PUT /api/v1/(ClassName)/(ID)/(Relation)` - updates a relation, replacing the existing record(s) (NOT IMPLEMENTED YET)
- `POST /api/v1/(ClassName)/(ID)/(Relation)` - updates a relation, appending to the existing record(s) (NOT IMPLEMENTED YET)
- DELETE /api/v1/(ClassName)/(ID) - deletes a database record (NOT IMPLEMENTED YET)
- DELETE /api/v1/(ClassName)/(ID)/(Relation)/(ForeignID) - remove the relationship between two database records, but don't actually delete the foreign object (NOT IMPLEMENTED YET)
- POST /api/v1/(ClassName)/(ID)/(MethodName) - executes a method on the given object (e.g, publish)
## Search
You can trigger searches based on the fields specified on `DataObject::searchable_fields` and passed
through `DataObject::getDefaultSearchContext()`. Just add a key-value pair with the search-term
to the url, e.g. /api/v1/(ClassName)/?Title=mytitle.
## Other url-modifiers
- `&limit=<numeric>`: Limit the result set
- `&relationdepth=<numeric>`: Displays links to existing has-one and has-many relationships to a certain depth (Default: 1)
- `&fields=<string>`: Comma-separated list of fields on the output object (defaults to all database-columns).
Handy to limit output for bandwidth and performance reasons.
- `&sort=<myfield>&dir=<asc|desc>`
- `&add_fields=<string>`: Comma-separated list of additional fields, for example dynamic getters.
## Access control
Access control is implemented through the usual Member system with BasicAuth authentication only.
2012-06-04 10:14:02 +02:00
By default, you have to bear the ADMIN permission to retrieve or send any data.
You should override the following built-in methods to customize permission control on a
class- and object-level:
- `DataObject::canView()`
- `DataObject::canEdit()`
- `DataObject::canDelete()`
- `DataObject::canCreate()`
See `SilverStripe\ORM\DataObject` documentation for further details.
2012-06-04 10:14:02 +02:00
You can specify the character-encoding for any input on the HTTP Content-Type.
At the moment, only UTF-8 is supported. All output is made in UTF-8 regardless of Accept headers.
