Useful utils for laravel/lumen

Install

composer require cao-jiayuan/laravel-api[:dev-master]

Providers

• Laravel CaoJiayuan\LaravelApi\LaravelApiServiceProvider
• Lumen CaoJiayuan\LaravelApi\LumenApiServiceProvider

Usage

1.Exception render

• Trait : CaoJiayuan/LaravelApi/Foundation/Exceptions/Traits/ExceptionRenderer.php
• Usage :

<?php

namespace App\Exceptions;
//......
use CaoJiayuan\LaravelApi\Foundation\Exceptions\Traits\ExceptionRenderer;
use Exception;
use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler;
//......

class Handler extends ExceptionHandler
{
    use ExceptionRenderer;
    //......
    public function render($request, Exception $exception)
    {
        return $this->renderException($request, $exception);
    }
}

2.Eloquent pipeline query

• Trait CaoJiayuan\LaravelApi\Database\Eloquent\Helpers\Pipelineable

• Usage

<?php
namespace App;

use CaoJiayuan\LaravelApi\Database\Eloquent\Helpers\Pipelineable;
use Illuminate\Database\Eloquent\Model;

class Foo extends Model {
    
    use Pipelineable;
    
    public function relate() {
        return $this->belongsTo(App\Bar::class);
    }
}

\App\Foo::pipeline('with:relate|select:id,name');//equals \App\Foo::with('relate')->select(['id','name'])->get();
\App\Foo::join('baz', 'foo_id', '=', 'baz_id')
          ->pipeline('with:relate|select:id,name,baz.title as baz|get|pluck:name|random');

3.Dummy data generator

Generate test data with giving template (inspired by Mock.js), working with fzaninotto/Faker

Usage:

template = [
    'key|rule1[:params][|rule2[:params]]' [=> 'value']
]
dummy(template) array|mixed
dummy_pager(total, template [,page=1] [,perPage=25]) LengthAwarePaginator

example:

<?php

dummy([
   'id' => 1,
   'name|name',
   'address|address',
   'data|list:2' => [
        'id|1+1',   
        'name|name',   
    ]
]);

results:

{
    "id":1,
    "name":"Mrs. Bulah Hilll MD",
    "address":"445 Hudson Isle\nJunehaven, NM 74631",
    "data":[
        {"id":1,"name":"Sophie Kris"},
        {"id":2,"name":"Cooper Thompson"}
    ]
}

rules:

• list[:size=20] generate array of data with giving template as value, alias l:size

• increase[:step=1,base=1] generate number auto-increase step from base in list template, alias base+step

• date[:format=Y-m-d H:i:s,now=time()] generate datetime string with format

• randDate[:start,end='now',format='Y-m-d H:i:s'] generate random datetime string between start and end

• rand[:min,max,value=null] generate random value, eg:

   <?php
    dummy('rand|1,100');// return random number between 1 and 100
    dummy('rand|true,false');
    dummy([
      'data|list:10|rand:1,5' => [// working with pipeline, generate 10 items, randomly take 1-5 item[s]
           'id|1+1',   
          'name|name',
       ]
    ]);
  

• pick[:num=1] pick num of item from value, if num = 1, return single item

• from return data from giving value

• db[:table,limit=null] get result from database with giving value as callback

   <?php
    dummy([
      'data1|db:users' => function(\Illuminate\Database\Query\Builder $builder) {
            /// database query
          $builder->select(['id', 'name']);
          /// ......
       },
       'data2|db:articles,2', /// randomly take 2 rows from table articles 
       'data3|db:connection1.articles,2', /// specified connection
       'data4|db:articles,10|pick:2' /// working with pipeline
    ]);
  

4.Helpers

RequestHelper

• Trait CaoJiayuan\LaravelApi\Http\Request\RequestHelper
• Method getValidatedData(array $rules, array $messages = [], array $customAttributes = [])

<?php
namespace App\Http\Controllers;

use CaoJiayuan\LaravelApi\Http\Request\RequestHelper;

class FooController extends Controller
{
    use RequestHelper;
    //
    
    public function post(){
        $data = $this->getValidatedData([
            'name' => 'required', // Key => Rule,
            'foo', //Only key [default null]
            'bar' => ['required'/* or null*/, 1], // // Key => [Rule, default],
            'baz' => ['required'/* or null*/, function($value){
                return $value + 1;
            }] // Key => [Rule, resolver],
        ], ['name.required' => '......'], ['foo' => '-_-!!!']);
