Laravel Route not working. Did not get The id - php

Question

I have now working on a project called Hospital & Doctor Information. Here I have different Division in Bangladesh & in each division there are districts in which there are certain types of hospital according to their ownership. But when I get the value of different hospital from it shows me some error.It did not find the specific id.I Have asked the ques before. But it did not solve my problem. So I ask this again. My route file
Route::get('/district/{id}', array('as' =>'district' ,'uses' => 'UserController#district'));
Route::get('/district/hospital/{id}', array('as' =>'hospital' ,'uses' => 'UserController#hospital'));
Route::get('/district/hospital/hospital_info/{id}', array('as' =>'hospital_info' ,'uses' => 'UserController#hospital_info'));
My Hospital Info Blade file is
<?php $active="hospital"; ?>
#extends('layouts.dashboard')
#section('content')
<section id="blog" class="container">
<div class="center">
<h2>Hospital Information</h2>
<h3 class="lead">The government approved a renowned hospital and improved quality of service address , doctor , patient viewing time, bed , pathological tests in various subjects including costs and find the information here .<br> The bed and cabin bookings online , pathological tests , the doctor can be a serial for the meeting from the app .</h3>

}
The District Model Is
<?php
namespace App;

return $this->hasMany('App\District','division_id');
}
}
The error is
I have asked the question a few days earlier but did not find the answer. Plz help me.

Answer 1

Your main problem is you're trying to get a hospital from id but you havn't defined any id in Hospital model so first thing first you should add id column to your Hospital model.
Secondly change your function from this
public function hospital_info($id)
{
$divisions = Division::all();
$division=Division::find($id);
$district=District::find($id);
$categories=Category::all();
$cats=Category::find($id);
$hospitals=Hospital::find($id);
// $districts=District::where('division_id', '=', $divisions->id)->get();
// if (!$district)
// {
// throw new NotFoundHttpException;
// }
return view('users.hospital_info')
->with('divisions', $divisions)
->with('division', $division)
->with('district', $district)
->with('categories',$categories)
->with('cats',$cats)
->with('hospitals',$hospitals);
}
To this
public function hospital_info($id)
{
$hospital=Hospital::find($id);
$divisions = Division::all();
$categories=Category::all();
// $districts=District::where('division_id', '=', $divisions->id)->get();
// if (!$district)
// {
// throw new NotFoundHttpException;
// }
return view('users.hospital_info') , compact('divisions','categories', 'hospital');
}
then you can get your infromation like this
<div class="col-xs-12 col-sm-6 blog-content">
<h2>{{ $hospital->name }}</h2>
</div>
#foreach($divisions as $itemDivision)
#foreach($categories as $itemCategory)
<div class="col-xs-12 col-sm-6 blog-content">
<h2>{{ $itemDivision->name }}</h2>
</div>
#endforeach
#endforeach
To get all the information about a District for example :
You should add the (id) column to all your models for using them later
inside your function do this :
public function district($id)
{
$district=District::findorfail($id);
$hospitals = DB::table('hospitals')
->leftjoin('districts' ,'hospitals.district_id' , '=', 'districts.id')
->where('district.id','=',$id)
->select('hospitals.*')
->get();
return view('users.district'),compact('district','hospitals') ;
}
Of course the hosptials is an array of objects and you should use a loop to get each hospital's informtaion
