Installation

Run the following command from you terminal:

composer require "omnicode/lara-repo: 2.0.*"

or add this to require section in your composer.json file:

"omnicode/lara-repo": "2.0.*"

then run composer update

Usage

First, create your RepositoryInterface interface that should extend LaraRepo\Contracts\RepositoryInterface

e.g.

<?php

namespace App\Repositories\Contracts;

use LaraRepo\Contracts\RepositoryInterface;

interface AccountRepositoryInterface extends RepositoryInterface
{
    
}

Next, create your repository class. Note that your repository class should extend LaraRepo\Eloquent\AbstractRepository and have modelClass() method

e.g.

<?php

namespace App\Repositories\Eloquent;

use LaraRepo\Eloquent\AbstractRepository;
use App\Repositories\Contracts\AccountRepositoryInterface;
use App\Models\Account;

class AccountRepository extends AbstractRepository  implements AccountRepositoryInterface
{
    public function modelClass()
    {
        return Account::class;
    }
}

modelClass() method is used to identify the model class

It is suggested to use LaraModel repository to utilize all the functionality

"omnicode/lara-model": "2.0.*"

and use

And you can create App\Models\Account model

<?php

namespace App\Models;

use LaraModel\Models\LaraModel;

class Account extends LaraModel
{
    
}

Next Bind it in ServiceProvider.

<?php

namespace App\Providers;

use App\Repositories\Contracts\AccountUserRepositoryInterface;
use App\Repositories\Eloquent\AccountRepository;
use Illuminate\Support\ServiceProvider;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Register any application services.
     *
     * @return void
     */
    public function register()
    {
        $this->app->bind(AccountUserRepositoryInterface::class, AccountRepository::class);
    }
}

And finally, use the repository in your controller or service layer

<?php

namespace App\Http\Controllers;

use App\Repositories\Contracts\AccountRepositoryInterface as AccountRepository;

class AccountsController extends Controller
{

    /**
     * @var AccountRepository
     */
    protected $accountRepository;

    /**
     * AccountsController constructor.
     * @param AccountRepository $accountRepository
     */
    public function __construct(AccountRepository $accountRepository)
    {
        $this->accountRepository = $accountRepository;
    }

    /**
     * @return \Illuminate\Contracts\View\Factory|\Illuminate\View\View
     */
    public function index()
    {
        $items = $this->accountRepository->all(); 
        return view('accounts.index', compact('items'));
    }
}

Example usage

Create a new account repository:

e.g.

    
    $this->accountRepository->create($request->all());
    
    $this->accountRepository->createWith($request->all(), 'name', $name);
    
    it is equivalent 
    
    $data = array_merge($request->all(), ['name' => $name])
    $this->accountRepository->create($data);
    
    //if your model extends LaraModel/Models/LaraModel you can use saveAssociated Method for saving new account
    //or update existing model with relations
    $this->accountRepository->saveAssociated($data, $relations);
    
    //for updating with relations
    $this->accountRepository->saveAssociated($data, $relations, $account);

Update existing account:

    // update based on id
    $this->accountRepository->update($request->all(), $accountId);

    // update based on attribute
    $this->accountRepository->update($request->all(), $attribute, 'attribute');
    
    // for increment attribute with value
    $this->accountRepository->increment($attribute, $value);
    
    //for decrement attribute with value
    $this->accountRepository->decrement($attribute, $value);

Delete account:

    // delete by id
    $this->accountRepository->destroy($accountId);

Find account(s) and specify columns with you want to fetch

    // find by accountId
    $this->accountRepository->find($accountId, $columns);
    
    // find by attribute (first occurence)
    $this->accountRepository->findBy($attribute, $value, $columns);
    
    // find by attribute (all occurence)
    $this->accountRepository->findAllBy($attribute, $value, $columns);
    
    // to find and return exact attribute 
    $this->accountRepository->findAttribute($accountId, $attribute);
    
    // to find account by accountId with fillable columns
    $this->accountRepository->findFillable($accountId);
    
    // to find account by attribute with fillable columns
    $this->accountRepository->findFillableWhere($id, $attribute, $value, $cmp = '=')

    // to find all accounts by attribute with fillable columns use
    $this->accountRepository->findAllFillable($attribute, $value);

    // to find account with relations
    $this->accountRepository->findFillableWith($id, $related = [])
    

    // to find all accounts
    $this->accountRepository->all($columns)
    
    // to find first account
    $this->accountRepository->first($columns = null)
    
    //for find last account
    $this->accountRepository->last($columns = null)
    
    // if your model extends LaraModel\Models\LaraModel
    // and $showable property is specified you can use
    $this->accountRepository->findForShow($id, $columns = null)
    
    // if your model extends LaraModel\Models\LaraModel
    // and specifed $listable property you can use
    // for find accounts list 
    //[
    //      1 => 'account1',
    //      2 => 'account2'
    //]
    //
    $this->accountRepository->findList($active = true, $listable = null)
    
    // or you can use to find by attribute
    $this->accountRepository->findListBy($attribute, $value, $active = true, $listable = null)
    
    
    // to check if account exists with id
    $this->accountRepository->exists($id);
    
    // to find count of rows matching the given critera
    $this->accountRepository->findCount($attribute, $value, $cmp);
    
    // to check if item exists with given attribute and value
    $this->accountRepository->existsWhere($attribute, $value);
    
    // for pagination
    $this->accountRepository->paginate();
    
    // for pagination based by condition
    $this->accountRepository->paginateWhere($attribute, $value);

model related methods


    // to get the binded model    
    $this->account->getModel();

    // get current model query
    $this->account->getModelQuery();

    // to reset model query    
    $this->account->resetModelQuery();

    // to get model's table name
    $this->account->getTable();

    // to get model table's primary key
    $this->account->getKeyName();

    // to get model's fillable columns
    $this->account->getFillableColumns();

if your model extends LaraModel\Models\LaraModel you can also use this methods

    // returns columns including table name
    $this->accountRepository->fixColumns($columns, $table = null, $prefix = null);

    // returns indexable columns
    $this->account->getIndexableColumns($full = false, $hidden = true, $group = self::GROUP);

    // returns columns based on $showable property
    $this->accountRepository->getShowableColumns($full = false, $hidden = true, $group = self::GROUP);

    // returns serchable columns
    $this->accountRepository->getSearchableColumns();

    // returns listable columns
    $this->accountRepository->getListableColumns();

    // returns sortable columns
    $this->accountRepository->getSortableColumns($column = null, $group = self::GROUP);

    // returns status column
    $this->accountRepository->getStatusColumn();

    // add sorting options in columns
    $this->accountRepository->setSortingOptions($column = null, $order = 'asc', $group = self::GROUP);

    // returns model relations
    $this->accountRepository->getRelations();

Transaction methods


    $this->accountRepository->startTransaction();
    
    $this->accountRepository->commitTransaction();
    
    $this->accountRepository->rollbackTransaction();
LaraRepo\Contracts\Criteria\Criteria
    public abstract function apply($modelQuery, RepositoryInterface $repository);

Criteria

Criteria is a simple way to apply specific condition, or set of conditions to the query

Available Criteria

The following criteria are available:

    LaraRepo\Criteria\Distinct\DistinctCriteria
    LaraRepo\Criteria\Group\GroupByCriteria             __construct($columns)
    LaraRepo\Criteria\Has\HasCriteria                   __construct($columns, $value, $cmp = '=')
    LaraRepo\Criteria\Join\InnerJoinCriteria            __construct($relation, $column = '', $values = [])
    LaraRepo\Criteria\Join\InnerJoinRelationCriteria    __construct($relation, $otherKeys = [])
    LaraRepo\Criteria\Join\LeftJoinCriteria             __construct($relation, $column = '', $values = [])
    LaraRepo\Criteria\Limit\LimitCriteria               __construct($limit)
    LaraRepo\Criteria\Offset\OffsetCriteria             __construct($offset)
    LaraRepo\Criteria\Order\SortCriteria                __construct($column, $order = 'asc', $fixColumns = true)
    LaraRepo\Criteria\Search\SearchCriteria             __construct($value, $columns = null, $table = null)
    LaraRepo\Criteria\Select\SelectCriteria             __construct($columns = [], $table = null)
    LaraRepo\Criteria\Select\SelectFillableCriteria     __construct($include = [], $exclude = [])             
    LaraRepo\Criteria\Select\SelectCriteria             __construct($relation, $columns, $prefix = true)
    LaraRepo\Criteria\Where\ActiveCriteria
    LaraRepo\Criteria\Where\BetweenCriteria             __construct($column, $from, $to)
    LaraRepo\Criteria\Where\OrWhereCriteria             __construct($attribute, $value, $cmp = '=') 
    LaraRepo\Criteria\Where\WhereCriteria               __construct($attribute, $value, $cmp = '=')
    LaraRepo\Criteria\Where\WhereHasRelationCriteria    __construct($relation, $where = [])
    LaraRepo\Criteria\Where\WhereInCriteria             __construct($attribute, $values = [])
    LaraRepo\Criteria\Where\WhereRelationCriteria       __construct($relation, $attribute, $value, $cmp = '=')
    LaraRepo\Criteria\With\RelationCriteria             __construct($relations = [])
    LaraRepo\Criteria\With\WithCountCriteria             __construct($relations)

You can make your own Criteria. Your criteria class MUST extend the abstract LaraRepo\Criteria\Criteria class.

For exapmle:

<?php
namespace YourNamespace;

use LaraRepo\Contracts\RepositoryInterface;
use LaraRepo\Criteria\Criteria;

class NewCriteria extends Criteria
{
    
    public function __construct()
    {
        //your code
    }

    /***
     * @param $modelQuery
     * @param RepositoryInterface $repository
     * @return mixed
     */
    public function apply($modelQuery, RepositoryInterface $repository)
    {
        //your code here
        return $modelQuery;
    }

}

Now, inside you controller class you call pushCriteria method:

<?php

namespace App\Http\Controllers;

use LaraRepo\Criteria\Where\WhereCriteria;
use App\Repositories\Contracts\AccountRepositoryInterface as AccountRepository;

class AccountsController extends Controller
{

    /**
     * @var AccountRepository
     */
    protected $repository;

    /**
     * AccountsController constructor.
     * @param AccountRepository $accountRepository
     */
    public function __construct(AccountRepository $accountRepository)
    {
        $this->repository = $accountRepository;
    }

    /**
     * @return \Illuminate\Contracts\View\Factory|\Illuminate\View\View
     */
    public function index()
    {
        $this->repository->pushCriteria(new WhereCriteria('id', '15', '>'));
        $items = $this->repository->all(); 
        return view('accounts.index', compact('items'));
    }
}
