yii2-apigql provides methods to work with database on CRUD operations

Usage

API docs

For example we have 3 table/models: Users, Messages, Post.

• Users -> hasMany Post
• Post -> hasMany Messages

We want to access clients with all messages including post:

{
  "username": "",
  "avatarUrl": "",
  "post": {
    "postName":"",
    "messages": {
      "textMessage": "",
      "dateAdded": ""
    }
  }
}

Make request and get all data with the same format you provided.

GET /clients?select={"username": "","avatarUrl": "","post": {"postName": "","messages": {"textMessage": "","dateAdded": ""}}}

// response
{
    "username": "Andyhar",
    "avatarUrl": "http://example.com/andyhar.png",
    "post": [
      {
        "postName": "Post about API",
        "dateAdded": "1500276204",
        "messages": [
          {
            "textMessage": "Hey what a nice post!",
            "dateAdded": "1500276704",
          },
          {
            "textMessage": "Make more posts like this!",
            "dateAdded": "1500279841",
          }
        ]
      },
    ]
  }

• Access main model and nested relations data with one query.
• Sort by nested relations:
  • /clients?select={...}&sort=post.postName - sort by post.postName ASC
  • /clients?select={...}&sort=!post.messages.dateAdded - sort by post.messaged.dateAdded DESC
• Filter data with nested conditions:
  • /clients?select={"username":"=Andyhar"} - where username equals Andyhar
  • /clients?select={"post":{"messages":{"textMessage":"~Rocks"}}} - where post.messages.textMessage like Rocks
  • /clients?select={"post":{"likes":">35"}} - where post.likes > 35

Installation

The preferred way to install this extension is through composer. Either run

composer require andyharis/yii2apigql

Getting started

After installation you should enable this module extension in your config file:

1. Open your frontend/config/main.php
2. Add module gql to bootstrap section

// main.php
return [
  'id' => 'app-frontend',
  'basePath' => dirname(__DIR__),
  'bootstrap' => ['log', 'gql'],
   // your code
];

Then you need to initialize component itself. Just add new component gql to list of your components:

// main.php
'components' => [
   'gql' => [
     'class' => "andyharis\yii2apigql\Bootstrap",
     'relations' => require 'models.php'
    ],
    // your code
]

Creating file models.php

As you can see we require 'models.php' to let component know which models to use.

So you probably want create a separate file to store you models for this case.

// models.php
use andyharis\yii2apigql\components\api\Relations;
// Initializing component relations class which will handle dependencies
$object = new Relations();
// Add all models you need to work with
$object
  ->addModel(String $name, String $className)
  ...
  ...
  ->addModel('clients', \frontend\models\Clients::className())
  ->addModel('job', \frontend\models\Job::className());
// we need to return this object with relations
return $object;

Where:

• clients - indicates name for your model
• \frontend\models\Clients::className() - indicates what model should use to fetch and update data

Almost there

Another important thing is to extend all your models with Yii2ApigqlRecord component.

// frontend/models/Clients.php
namespace frontend\models;

use andyharis\yii2apigql\components\Yii2ApigqlRecord;
// This is important, because Yii2ApigqlRecord has some methods which use your models to make magic. 
// Of course you can extend it with your class but don't forget to extend Yii2ApigqlRecord
class Clients extends Yii2ApigqlRecord

That's it. Now you can work with yii2apigql.
