## Installation

## Usage

### Simple
````
// creating postModel on-the-fly, just pass a table name
$postModel = \Arifrh\DynaModel\DB::table('posts');

// then you can use it, to get all posts
$postModel->findAll();
````

### Many-to-One Relationship
````
// assume that posts always belongs to one author using author_id
$postModel->belongsTo('authors);

// then you can grab author info along with posts
$postModel->with('authors')->findAll();

/**
* by default, primary key of authors will be omit in the column result
* because its value already exist in the foregin key of relationship
*
* if authors has same column name with posts, then it will be aliased with prefix "author_"
* for example, both posts and authors has "rating" column, then it will become author_rating
*/

// you can call only spesific column if you need, pass it on the second parameters in array
$postModel->with('authors', ['name', 'rating'])->findAll();
// will display all posts column, plus author name and author rating

// you can filter posts based on author criteria
$postModel->with('authors')->whereRelation('authors', ['status' => 'active'])->findAll();
// will display all posts only from active authors
````

### One-to-Many Relationship
````
$postModel->hasMany('comments');

// this will return posts with all related comments
$postModel->with('comments')->findAll();

// you can also filter posts based on comments criteria
$postModel->with('comments')->whereRelation('comments', ['status' => 'approved'])->findAll();
// will display all posts with approved comments only
