Laravel - collection table - php

Question

There are two tables, a table with streets, and a table with information about the house.
I tried to join the tables using the street_id column in the houses table. The table works, I get the information. But now how can I make it so that when I click on the street / {ID} link, I get a list of houses that are located on it.
As I understand it, it is necessary to add the code
public function getHouse()
{
$houses = Houses::where('street_id', $this->street_id)->get();
dd ($houses);
}
DD get it wait. Where did I go wrong?

Answer 1

You may do like this below.
Street Model:-
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class Street extends Model
{
public function houses()
{
return $this->hasMany('App\Models\House');
}
}
House Model:-
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class House extends Model
{
public function street()
{
return $this->BelongsTo('App\Models\Street','street_id');
}
}
HouseController:-
<?php
namespace App\Http\Controllers;
use App\Models\Street;
use App\Models\House;
class HouseController extends Controller
{
public function getHouse($street_id)
{
//include model
dump($street_id); // first you can get street_id
// You can use with()
$houses = House::with('street')->where('street_id',$street_id)->get();
or
// also you can use whereHas()
$houses = House::whereHas('street', function($q) use($street_id){
$q->where('id',$street_id);
})->get();
or
$houses = Street::with('houses')->where('id',$street_id)->get();
}
}
Hope that helps.

You can achieve this with laravel's Eloquent relationships. You need to declare the relationship in the Street Model file like this...
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class Street extends Model
{
/**
* Get the houses on the street.
*/
public function houses()
{
return $this->hasMany(House::class);
}
}
now in your controller where you return the view for houses on a street, you can do this;
$houses = Street::find(1)->houses();
<?php
namespace App\Http\Controllers;
use App\Models\Street;
use Illuminate\Http\Request;
class StreetsController extends Controller
{
/**
* Display a listing of the resource.
*
* #return \Illuminate\Http\Response
*/
public function index()
{
$street = Street::all();
return view('street.all', compact('street'));
}
/**
* Show the form for creating a new resource.
*
* #return \Illuminate\Http\Response
*/
public function create()
{
//
}
/**
* Store a newly created resource in storage.
*
* #param \Illuminate\Http\Request $request
* #return \Illuminate\Http\Response
*/
public function store(Request $request)
{
//
}
/**
* Display the specified resource.
*
* #param \App\Models\Appartaments $appartaments
* #return \Illuminate\Http\Response
*/
public function show($id)
{
$street = Street::find(1)->houses();
// $house = $street->houses;
dd($street);
return view('street.view', compact('street'));
}
/**
* Show the form for editing the specified resource.
*
* #param \App\Models\Appartaments $appartaments
* #return \Illuminate\Http\Response
*/
public function edit(Appartaments $appartaments)
{
//
}
/**
* Update the specified resource in storage.
*
* #param \Illuminate\Http\Request $request
* #param \App\Models\Appartaments $appartaments
* #return \Illuminate\Http\Response
*/
public function update(Request $request, Appartaments $appartaments)
{
//
}
/**
* Remove the specified resource from storage.
*
* #param \App\Models\Appartaments $appartaments
* #return \Illuminate\Http\Response
*/
public function destroy(Appartaments $appartaments)
{
//
}
}
