I want to response JSON with Laravel that I have CategoryModel belongTo SongModel.
This is my CategoryModel
class CategoryModel extends Model
{
protected $table = 'categories';
protected $fillable = [
'id',
'name',
];
public function song()
{
return $this->hasMany(SongModel::class);
}
}
And this is my SongModel
class SongModel extends Model
{
protected $table = 'songs';
protected $fillable = [
'id',
'name',
'url',
'categories_id',
'singers_id',
'types_id',
];
public function category()
{
return $this->belongsTo(CategoryModel::class);
}
}
I want to response JSON with the relationship. I wrote:
class SongController extends Controller
{
public function index(SongModel $songModel)
{
$song = $songModel->category()->get();
return response()->json(["DATA" => $song], 201);
}
}
To do this you will just need to load the relationship before you return the response:
public function index(SongModel $songModel)
{
$songModel->load('category');
return response()->json(["DATA" => $songModel], 201);
}
https://laravel.com/docs/5.4/eloquent-relationships#lazy-eager-loading
Hope this helps!
Try this. return response()->json(["DATA" => $songModel->load('category')->toArray()], 201);
OR, you can use with('song')
lass SongController extends Controller
{
public function index(SongModel $songModel)
{
$song = $songModel::with('song')->get();
return response()->json(["DATA" => $song], 201);
}
}

I have four tables:
Agroindustria
Pessoa
PessoaJuridica
Endereco
. Here are their Models:
Agroindustria
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
class Agroindustria extends Model
{
use SoftDeletes;
protected $table = "agroindustria";
protected $primaryKey = "CodAgroindustria";
public $incrementing = false;
protected $keyType = 'string';
public $fillable = ['CodAgroindustria, Porte'];
public $hidden = ['created_at', 'updated_at', 'deleted_at'];
public function pessoa () {
return $this->setConnection('diana')->hasOne(Pessoa::class, 'CodPessoa', 'CodAgroindustria');
}
public function pessoajuridica()
{
return $this->setConnection('diana')->hasOne(PessoaJuridica::class, 'CodPessoa', 'CodEndereco');
}
public function endereco()
{
return $this->setConnection('diana')->hasOne(PessoaJuridica::class, 'CodEndereco', 'CodEndereco');
}
public function estado(){
return $this->setConnection('diana')->hasOne(Estado::class, 'CodEstado', 'estado');
}
public function cidade(){
return $this->setConnection('diana')->hasOne(Cidade::class, 'CodCidade', 'cidade');
}
}
Pessoa:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
class Pessoa extends Model
{
// use SoftDeletes;
protected $table = "pessoa";
protected $primaryKey = "CodPessoa";
public $incrementing = false;
protected $keyType = 'string';
protected $connection = "diana";
public $hidden = ['created_at', 'updated_at', 'EXCLUIDO', 'LastSend'];
public $fillable = ['email', 'TelRes', 'TelCel'];
public function endereco()
{
return $this->hasOne('App\Endereco', 'CodEndereco', 'CodEndereco');
}
public function pessoafisica()
{
return $this->hasOne('App\PessoaFisica', 'CodPessoaFisica', 'CodPessoa');
}
public function pessoajuridica()
{
return $this->hasOne('App\PessoaJuridica', 'CodPessoaJuridica', 'CodPessoa');
}
}
The PessoaJuridica and Endereco Models are pretty much the same as the Pessoa Model.
When I soft delete my Agroindustria, the deleted_at column updates successfully, but I'm struggling with updating the EXCLUIDO column values from 0 to 1 in my other models.
Here's the delete function I created in my AgroindustriaController:
public function deletar (Request $request)
{
try {
$Agroindustria = Agroindustria::where('CodAgroindustria', $request['CodAgroindustria']);
$Agroindustria->delete();
$Pessoa = Pessoa::findOrFail($request['CodPessoa']);
if ($Agroindustria->delete()) {
DB::table('Pessoa')->where('CodPessoa', $Pessoa->CodPessoa)
->update(array('EXCLUIDO' => 1));
}
return response()->json([
'error' => false,
'data' => [
'message' => 'Dados deletados com sucesso',
]
]);
} catch (Exception $e) {
return response()->json([
'error' => true,
'message' => [$e->getMessage()]
]);
}
}
second line in try
$Agroindustria->delete();
write this line like this
$dlt = $Agroindustria->delete();
after that in your if condition put this variable $dlt like this
if ($dlt) {
DB::table('Pessoa')->where('CodPessoa', $Pessoa->CodPessoa)
->update(array('EXCLUIDO' => 1));
}
Solved it by doing:
$Agroindustria = Agroindustria::where('CodAgroindustria', $request['CodAgroindustria']);
$dlt = $Agroindustria->delete();
if ($dlt) {
Pessoa::where('CodPessoa', $request['CodPessoa'])
->update(array('EXCLUIDO' => 1));
PessoaJuridica::where('CodPessoaJuridica', $request['CodPessoaJuridica'])
->update(array('EXCLUIDO' => 1));
Endereco::where('CodEndereco', $request['CodEndereco'])
->update(array('EXCLUIDO' => 1));
}
Thank you all!
I'm getting the following error whenever i go on to a users page, its supposed to show if the authenticated user is already following the user that the profile is on.
Could this be a problem with the relationship setup, it hasMany

As Jonas Staudenmeir stated, followedByMe isn't a relationship, it's a regular function and what it does is returning a boolean. I'm confused at why you've got a follow on your user model and trying to get information from the follow's follower? Just simplify, I see too much unneeded eager loading here.
Searching by indexed elements (id) > searching by name, any day of the week
Edit:
UserController
public function getProfile(Request $request, $id)
{
//$request->user() will get you the authenticated user
$user = User::with(['posts.likes','followers','follows','followers.follows'])
->findOrFail($request->user()->id);
//This returns the authenticated user's information posts, likes, followers, follows and who follows the followers
//If you wish to get someone else's information, you just switch
//the $request->user()->id to the $id if you're working with id's, if you're
//working with names, you need to replace findOrFail($id) with ->where('name',$name')->get() and this will give you
//a collection, not a single user as the findOrFail. You will need to add a ->first() to get the first user it finds in the collection it results of
//If you're planning on getting an attribute (is_following = true) to know if
//the authenticated user is following, you can use an accessor in the User model and write this after you've fetched the instance of the User
//$user->append('is_following');
return view ('profile')->with('user', $user);
}
User Model
//Accessor
//People who this user follows
public function getIsFollowingAttribute()
{
return MyFollow::where('followable_id',$this->attributes['id'])->where('user_id',Auth()->user()->id)->count() > 0 ? true : false;
}
//Relationships
//People who this user follows
public function follow()
{
return $this->hasMany('App\MyFollow','user_id','id');
}
//People who follows this user
public function followers()
{
return $this->hasMany('App\MyFollow','followable_id','id');
}
//Posts of this user
public function posts()
{
return $this->hasMany('App\Post','user_id','id');
}
//Likes of this user, not sure about this one tho, we're not using this for now but it could come in handy for you in the future
public function likes()
{
return $this->hasManyThrough('App\Likes','App\Post','user_id','user_id','id');
}

//Who like this post
public function likes()

}
//Relationships

With the help of #abr i found a simple fix, simple solution.
MyFollow.php(model)
public function followers()
{
return $this->hasMany('App\MyFollow','followable_id','user_id');
}
//Relationships
//People who this user follows
public function follow()
{
return $this->hasMany('App\MyFollow','user_id','followable_id');
}
User.php(model)
public function getIsFollowingAttribute()
{
return MyFollow::where('followable_id',$this->attributes['id'])->where('user_id',Auth()->user()->id)->count() > 0 ? true : false;
}
public function follow()
{
return $this->hasMany('App\MyFollow');
}
UserController.php
public function getProfile($user)
{
$users = User::with(['posts.likes' => function($query) {
$query->whereNull('deleted_at');
$query->where('user_id', auth()->user()->id);
}, 'followers','follow.followers'])
->with(['followers' => function($query) {
}])->where('name','=', $user)->get();
$user = $users->map(function(User $myuser){
$myuser['followedByMe'] = $myuser->getIsFollowingAttribute();
return $myuser;
});
if(!$user){
return redirect('404');

return view ('profile')->with('user', $user);

it works now. :)
i have relation between Service and Services_Gallery one to many, and i want to use id of Service when i insert new image to Services_Gallery, and this is my Controller:
public function save(Request $request)
{
$this->validate($request,[
'image' => 'required|image|mimes:jpeg,jpg,png,svg|max:1024'
]);
$services_Gallery = new Services_Gallery();
$services_Gallery->image = $request->image->move('Uploads', str_random('6') . time() . $request->image->getClientOriginalName());
$services_Gallery->Service::all(id) = $request->service_id; //The problem here
$services_Gallery->save();
return back();
}
this is my Models:
class Service extends Model
{
protected $table = 'services';
protected $fillable = [
'en_main_title',
'ar_main_title',
'en_sub_title',
'ar_sub_title',
'en_content_title',
'ar_content_title',
'en_content',
'ar_content',
'priority',
];
public function gallery()
{
return $this->hasMany('App\Services_Gallery','service_id');
}
}
class Services_Gallery extends Model
{
protected $table = 'services_galleries';
protected $fillable = [
'image',
'service_id',
];
public function gallery(){
return $this->belongsTo('App\Service','service_id');
}
}
Exapmle:
$modelOfService = Service::where('param_x', $request->service_id)->first();
$id = $modelOfService->id;
Is that you need?
I have in model Report following
public function reportedItem()
{
return $this->belongsTo('App\Item', 'item_id', 'id');
}
In Item model
public function report()
{
return $this->hasMany('App\Report', 'item_id','id');
}
In controller
public function details( $item_id )
{
$flags = Item::find($item_id)->report->unique('user_id');
return view('flags.details', compact('flags'));
}
Why when I do {{ dd(collect($flags)) }} in my view.blade I don't see anything from items table even when I query it Item::find($item_id)?
dd output
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Report extends Model
{
protected $table = 'reports';
protected $primaryKey = 'report_id';
protected $fillable = [
'item_id', 'report_body', 'user_id', 'report_reason'
];
public function reportedItem()
{
return $this->belongsTo('App\Item', 'item_id', 'id');
}
public function user()
{
return $this->hasOne('App\User', 'id', 'user_id');
}
}
One way is to use something like this in your controller
public function details( $item_id )
{
$flags = Report::with('reportedItem')->where('item_id', '$item_id')->get();
try this
$flags = Item::find($item_id)->with('report')->get()
The below should work
$flags = Item::with('reportedItem')->find($item_id);
Then when you dd($flags) this look for the "relations" tab and inside that you'll see the info.
I have these models with their related db tables,at the moment I can retrieve all the requirement
Requirement::all()
but I just have a list of foreigns key (destination_id,applier_id,doc_id). How can i retrieve directly the row connected to that foreigns key?
class Requirement extends Model
{
protected $fillable = [
'required',
'destination_id',
'applier_id',
'doc_id'
];
public function destination()
{
return $this->belongsTo(Destination::class);
}
public function applier()
{
return $this->belongsTo(Applier::class);
}
public function doc()
{
return $this->belongsTo(Doc::class);
}
}
class Doc extends Model
{
protected $fillable = [
'type',
'description',
'note'
];
public function requirements()
{
return $this->hasMany(Requirement::class);
}
}
class Destination extends Model
{
protected $fillable = [
'country',
'passying_country',
'transfer_conditions',
'passing_conditions'
];
public function requirements()
{
return $this->hasMany(Requirement::class);
}
}
You can call with() function instead of all(). So if you try this following :
$requirements = Requirement::with('destination', 'applier', 'doc')->get();
Make it dd($requirements) and look the output.
Hope it will work.
