I have two tables as below
pscustom_catalog_product_entity
pscustom_catalog_product_entity_media
I have created collection for table pscustom_catalog_product_entity using resource model and block.
Now I can access this table data using collection.
app/code/MyModule/Productsinfo/Model/Product.php
<?php
namespace MyModule\Productsinfo\Model;
use Magento\Framework\Model\AbstractModel;
use MyModule\Productsinfo\Model\ResourceModel\Product as ResourceModel;
class Product extends AbstractModel
{
protected function _construct()
{
$this->_init(ResourceModel::class);
}
}
app/code/MyModule/Productsinfo/Model/ResourceModel/Product.php
<?php
namespace MyModule\Productsinfo\Model\ResourceModel;
use Magento\Framework\Model\ResourceModel\Db\AbstractDb;
class Product extends AbstractDb
{
protected function _construct()
{
$this->_init('pscustom_catalog_product_entity', 'entity_id');
}
}
app/code/MyModule/Productsinfo/Model/ResourceModel/Product/Collection.php
<?php
namespace MyModule\Productsinfo\Model\ResourceModel\Product;
use Magento\Framework\Model\ResourceModel\Db\Collection\AbstractCollection;
use MyModule\Productsinfo\Model\Product as Model;
use MyModule\Productsinfo\Model\ResourceModel\Product as ResourceModel;
class Collection extends AbstractCollection
{
protected function _construct()
{
$this->_init(Model::class, ResourceModel::class);
}
}
app/code/MyModule/Productsinfo/Block/Product.php
<?php
namespace MyModule\Productsinfo\Block;
use Magento\Framework\View\Element\Template;
use MyModule\Productsinfo\Model\ResourceModel\Product\Collection;
class Product extends Template
{
/**
* #var Collection
*/
private $collection;
/**
* Hello constructor.
* #param Template\Context $context
* #param Collection $collection
* #param array $data
*/
public function __construct(
Template\Context $context,
Collection $collection,
array $data = []
)
{
parent::__construct($context, $data);
$this->collection = $collection;
}
public function getAllProducts() {
return $this->collection;
}
I can get product collection using getAllProducts() method.
Now I want to join table pscustom_catalog_product_entity collection to table pscustom_catalog_product_entity_media. I have tried many solution but its not working.
Any help would be appreciated.
Thanks.
I think you can join tables in following way:
$this->getSelect()->join(
['secondTable'=>$this->getTable('pscustom_catalog_product_entity')],
'main_table.id = secondTable.entity_id','*');
$this->getSelect()->join(
['thirdTable'=>$this->getTable('pscustom_catalog_product_entity_media')],
'main_table.id = thirdTable.entity_id', '*');
}
This is the simplest way of joining two tables in collection

I am trying to learn more about Laravel ORM and ORM in general,
but I have problems I can't solve by myself.
This is my users table:
And here is my Article table:
My User eloquent model:
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class User extends Model
{
/**
* The table associated with the model.
*
* #var string
*/
protected $table = 'users';
public function article()
{
return $this->hasMany('\App\Models\Article', 'autor_id');
}
}
And my Article eloquent model:
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class Article extends Model
{
/**
* The table associated with the model.
*
* #var string
*/
protected $table = 'clanky';
public function autor() {
return $this->belongsTo('\App\Models\User', 'id');
}
}
I am trying to access each article with its author data using this code:
$articles = Models\Article::all();
foreach($articles as $art)
{
echo $art->autor->name . "<br>";
}
The problem is the model is returning only userdata from first article, not the second and so on.
Any thoughts on what could cause this? Thanks in advance.
I think you need to update your code like.
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class Article extends Model
{
/**
* The table associated with the model.
*
* #var string
*/
protected $table = 'Article';
public function autor() {
return $this->belongsTo('\App\Models\User', 'autor_id', 'id');
}
}
$articles = Models\Article::with('autor')->get();
foreach($articles as $art)
{
echo $art->autor->name . "<br>";
}
I am looking for solutions, but can't really understand. I'm new in Laravel and I want a simple instruction on how to use one model for multiple tables like CodeIgniter as follows:
Controller myController:
public function shipBuilding()
{
$data = $this->input->post();
$response = $this->MyModel->shipbuildingSave($data);
}
public function contact()
{
$data = $this->input->post();
$response = $this->MyModel->contactSave($data);
}
Model MyModel:
public function shipbuildingSave($data){
$this->db->insert('tbl_shipbuilding', $data);
return $this->db->insert_id();
}
public function contactSave($data){
$this->db->insert('tbl_contact', $data);
return $this->db->insert_id();
}
This is not how models work in Laravel. each model should be a representation of one single table.
You could, however, change the table name on booting the model up:
class Flight extends Model
{
/**
* The table associated with the model.
*
* #var string
*/
protected $table = 'example';
/**
* The "booting" method of the model.
*
* #return void
*/
protected static function boot()
{
parent::boot();
static::addGlobalScope(new AgeScope);
// Set the $this->table depending on some logic.
}
}
But again, this is probably not recommended for your case.
I have two models as Project and Collaborator this is My tables
Project column
id
project_name
project_note
user_id
Collaborator Model
id
project_id
collaborator_id
I need join this models to get project_name instead project_id of Collaborator Model.
how can I do this. I read www.laravel.com documents but difficult to understand. help me in code...
project Model
<?php
namespace App;
use Auth;
use Illuminate\Database\Eloquent\Model;
class Project extends Model
{
/*
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = ['project_name', 'project_notes', 'project_status', 'due_date'];
public function scopePersonal($query)
{
return $query->where('user_id', Auth::user()->id);
}
//
}
collaborator Model
<?php
namespace App;
use Auth;
use Illuminate\Database\Eloquent\Model;
class Collaboration extends Model
{
protected $table = 'project_collaborator';
/*
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = ['project_id', 'collaborator_id'];
/*
* Get the user that is a collaborator on another project
* #return collection
*/
public function user()
{
return $this->belongsTo(User::class, 'collaborator_id');
}
/*
* Query scope to return information about the current project
* #param $query
* #param int $id
* #return query
*/
public function scopeProject($query, $id)
{
return $query->where('project_id', $id);
}
public function scopeColabo($query)
{
return $query->where('collaborator_id',Auth::user()->id);
}
}
Based on your comment, you need to add a relationship hasOne to your collaboration model:
class Collaboration extends Model
{
.....
public function project()
{
return $this->hasOne('App\Project');
}
.....
}
The method project() will define your relationship with your project model. And then you'll be able to get the collaboration project name like this:
$collaborations = Collaboration::with('project')->get();
foreach ( $collaborations as $collaboration ) {
echo $collaboration->project->project_name;
}
You can read more in the documentation.
In your Collaboration class add the followoing relation:
public function project()
{
return $this->belongsTo('App\Project');
}
And in your User class define a relation as:
public function collaborations()
{
return $this->hasMany('App\Collaboration', 'collaborator_id');
}
Then you can get all the collaborations of logged in user by:
$collaborations = auth()->user()->collaborations()->with('project')->get()
or
To get all collaborations you can so as:
$collaborations = Collaboration::with('project')->get();
In your view file:
#foreach ($collaborations as $collaboration)
{{ $collaboration->project->project_name }}
#endforeach
I'm new to Laravel 5 and I have some difficulties with pivot tables, controllers and repositories.
I have the tables 'users', 'sites', 'site_user', and here is what I have now :
App\Models\User
class User extends Model implements AuthenticatableContract, CanResetPasswordContract {
protected $table = 'users';
public function sites()
{
return $this->belongsToMany('App\Models\Site')
->withPivot('site_id', 'user_id', 'relation');
}
}
App\Models\Site
class Site extends Model {
protected $table = 'sites';
public function user()
{
return $this->belongsToMany('App\Models\User')
->withPivot('site_id', 'user_id', 'relation');
}
}
App\Repositories\SiteRepository
<?php namespace App\Repositories;
use App\Models\Site, App\Models\User;
class SiteRepository extends BaseRepository
{
/**
* The User instance.
*
* #var App\Models\User
*/
protected $user;
/**
* Create a new SiteRepository instance.
*
* #param App\Models\Site $site
* #return void
*/
public function __construct (Site $sites, User $user)
{
$this->model = $sites;
$this->user = $user;
}
/**
* Get sites collection paginate.
*
* #param int $n
* #return Illuminate\Support\Collection
*/
public function index($n)
{
return $this->model
->latest()
->paginate($n);
}
App\Http\Controllers\SiteController
<?php namespace App\Http\Controllers;
use App\Repositories\SiteRepository;
use App\Repositories\UserRepository;
use App\Http\Requests\SiteCreateRequest;
use App\Http\Requests\SiteUpdateRequest;
use App\Models\Site;
use App\Models\User;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
class SiteController extends Controller {
/**
* The SiteRepository instance.
*
* #var App\Repositories\SiteRepository
*/
protected $site_gestion;
/**
* The UserRepository instance.
*
* #var App\Repositories\UserRepository
*/
protected $user_gestion;
/**
* Create a new SiteController instance.
*
* #param App\Repositories\SiteRepository $site_gestion
* #param App\Repositories\UserRepository $user_gestion
* #return void
*/
public function __construct (SiteRepository $site_gestion, UserRepository $user_gestion)
{
$this->site_gestion = $site_gestion;
$this->user_gestion = $user_gestion;
$this->middleware('admin');
}
/**
* Display a listing of the resource.
*
* #return Response
*/
public function index(SiteRepository $site_gestion)
{
//$counts = $this->site_gestion->counts();
$sites = $site_gestion->index(25);
$links = $sites->render();
return view('back.sites.index', compact('sites'));
}
views\back\sites\table.blade.php
#foreach ($sites as $site)
[...some code...]
#endforeach
What I want to do is to get all the sites of the logged in user. I've tried many things, but none of them are working. And I'm still not sure where to put the code, repository or controller...
I've read tutorials about pivot in Laravel, and I've tried with some things like this in the repo, but it doesn't work...
$user = $this->user->find(auth()->user()->id); //This line is working
foreach ($user->sites as $site) {
return $site
->latest()
->paginate($n);
}
If you want all sites of a logged user simply do it like this:
$sites = Auth::user()->sites;
That's all you need to do to get to these sites. If you want to use query and pagination try like this:
$sites = Auth::user()->sites()->latest()->paginate($n);
So what you've done seems pretty close.
So you pretty much have it, when iterating over the sites they should be instances of the site model.
$user = auth()->user(); // This is a way of saying your first line without a db query for the user
foreach ($user->sites as $site) {
// each site in here is a site model
$site->pivot->relation;
}
The only other thing that looks slightly strange is how you've defined the pivots. Generally when calling withPivot you wouldn't define the joining ids, if you wish to vary from the defaults you can pass it as an argument to the belongsToMany like so.
return $this->belongsToMany('App\Models\User', 'site_user', 'user_id', 'site_id')
->withPivot('relation');
I am working on a project with Laravel 4.2 and I created some models and controllers and called model function from controller, the problem is after composer update command it displays this error: Call to undefined method Department::getAllParent() but before composer update it works fine. You think what is the problem with this issue? thanks in advance
Model code:
class Department extends Eloquent{
/**
* The database table used by the model.
*
* #var string
*/
protected $table = 'department';
public static function getAll()
{
$table = DB::table('department');
$object = $table->get();
return $object;
}
public static function getAllParent()
{
$table = DB::table('department');
$table->where('parent',0);
$object = $table->get();
return $object;
}
}
And Controller code:
class DepartmentController extends BaseController
{
/*
Getting all records from department
#param: none
#Accessiblity: public
#return: Object
*/
public function getAllDepartment()
{
//get data from model
$deps = Department::getAllParent();
$depAll = Department::getAll();
//load view for users list
return View::make("department.dep_list")->with('deps',$deps)->with('all',$depAll);
}
}
Don't think this is related to your issues but this might be a better way to handle these queries. you are using Eloquent and setting the table parameter. why not use Eloquent's build in power?
class Department extends Eloquent{
/**
* The database table used by the model.
*
* #var string
*/
protected $table = 'department';
public static function getAll()
{
return Department::get();
}
public static function getAllParent()
{
return Department::where('parent', 0)->get();
}
}
I think you might also be able to use $this->get(); but I can't test right now.
