Restful query parser trait for Laravel eloquent model

Add helper traits for restful query.

Installation

composer require wwtg99/restful-helper

Parse query

This trait parse url queries for eloquent model. Suppose you have a resource controller in route /users and connect to User model.

filters

Add filterableFields in your model.

$filterableFields = ['role'];

Then use /users?role=admin to get user with role admin.

Supported operators:

• equal: /users?id=1
• equal or greater than: /users?id>=1
• equal or less than: /users?id<=2
• not equal: /users?id!=1
• like: /users?id*=1

sorts

Use /users?sort=-role,created_at to sort by role desc and created_at asc, comma(,) to separate.

select fields

Use /users?fields=name,role,created_at to show only name, role and created_at. Also can config $selectableFields to restrict selectable fields.

$selectableFields = ['name', 'role'];

Then only name and role can be selected to show.

Use fields=count to count results /users?fields=count.

pagination

Use /users?limit=10&offset=10 to limit 10 and offset 10 records, offset can be omitted, default 0. Also can use page and page_size, /users?page=2&page_size=15, page_size can be omitted, default 15.

Usage

Eloquent model trait

1. Add RestHelper trait in eloquent model.

use RestHelperTrait;

2. Use index method.

$user = User::index()->get();
// Or, use custom inputs array
$user = User::index(request()->all())->get();

3. Also combine with other methods.

$user = User::index()->where('name', 'admin')->get();

Controller trait

1. Add RestfulController trait in resource controller.

use RestfulControllerTrait;

2. Implement getModel method.

protected function getModel()
{
    return User::query();
}

Model should use RestHelperTrait to have index function.

3. Add controller to routes

Route::resource('/path', 'controller');

4. Each resource method (index, show, store, update, destroy) has three parts.
   1. parse requests
   2. handle action
   3. response

Override these template functions to change the default behaviors.

Add $creatableFields = ['field1', 'field2'] to restrict fields to store. Add $updateableFields = ['field1', 'field2'] to restrict fields to update.

Batch Process

Add new route for batch process. Batch process read content body as json object.

• Get resources:

{"GET": [1,2,3]}

Use key GET and id array as value. Return data or error in the same sequence as query.

• Create resources:

{"CREATE": [{"name":"aaa"}, {"name":"bbb"}]}

Use key CREATE and object array as value. Return data or error in the same sequence as query.

• Update resources:

{"UPDATE": {"1": {"name":"ccc"}, "2": {"name": "ddd"}}}

Use key UPDATE, id and data pairs as value. Return data or error in the same sequence as query.

• Delete resources:

{"DELETE": [1,2,3]}

Use key DELETE and id array as value. Return {"code": 204} or error in the same sequence as query.

Batch Usage

1. Add RestfulControllerTrait in your Controller

class TestController extends Controller
{
    use RestfulControllerTrait;

    protected $creatableFields = ['name', 'email', 'password'];

    protected $updateableFields = ['email'];

    protected function getModel()
    {
        return User::query();
    }
}

2. Add route

Route::match(['GET', 'POST'], 'test/batch', 'TestController@batch');

3. Send batch query POST /test/batch {"GET":[1,2],"CREATE":[{"name":"aaa","email":"aa@a.com"}],"UPDATE":{"1":{"name":"bb"},"2":{"email":"b@b.com"}},"DELETE":[5,6]}

Return { "GET": [{"id":1, "name":"a", "email": "a@a.com"}, {"id":1, "name":"a", "email": "a@a.com"}], "CREATE": [{"id": 3, "name":"aaa", "email":"aa@a.com"}], "UPDATE": {"1": ["id":1, "name": "bb", "email": "a@a.com"], "2": ["id":2, "name":"a", "email":"b@b.com"], "DELETE": [{"code":204},{"code":204}] }
