I'm quite new to Laravel and now I'm trying to move parts of a former application from a small self written framework into Laravel. The address book is multilingual therefor the table structure is a little more complicated.
db-structure
And this is my source code:
AddressBookController.php
namespace App\Http\Controllers;
use App\AddressBook as AB;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator;
class AddressBookController extends Controller
{
/**
* Display a listing of the resource.
*
* #return \Illuminate\Http\Response
*/
public function index()
{
$entries = AB::all();
return view('addressBook')->with([
'class' => __CLASS__,
'function' => __FUNCTION__,
'line' => __LINE__,
'entries' => $entries,
]);
}
}
Model AddressBook.php
namespace App;
use Illuminate\Database\Eloquent\Model;
class AddressBook extends Model
{
protected $table = 'address';
protected $primaryKey = 'address_id';
protected $keyType = 'int';
public $incrementing = true;
public $timestamps = false;
protected $searchable = [
'columns' => [
'address.address_surname' => 10,
'address.address_company' => 5,
'address.address_vatid' => 2,
],
];
public function country() {
return $this->hasOne('country', 'country_id', 'country_id');
}
public function addresstype() {
return $this->hasOne('addresstype', 'addresstype_id', 'addresstype_id');
}
}
Model Country.php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Country extends Model
{
protected $table = 'country';
protected $primaryKey = 'country_id';
protected $keyType = 'int';
public $incrementing = true;
public $timestamps = false;
public function translation() {
return $this->hasOne('translations', 'translations_id', 'translations_id');
}
public function addressbook() {
return $this->belongsTo('address', 'country_id', 'country_id');
}
}
Model AddressType
namespace App;
use Illuminate\Database\Eloquent\Model;
class AddressType extends Model
{
protected $table = 'addresstype';
protected $primaryKey = 'addresstype_id';
protected $keyType = 'int';
public $incrementing = true;
public $timestamps = false;
public function translation() {
return $this->hasOne('translations', 'translations_id', 'translations_id');
}
public function addressbook() {
return $this->belongsTo('address', 'addresstype_id', 'addresstype_id');
}
}
Model Translation.php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Translation extends Model
{
protected $table = 'translations';
protected $primaryKey = 'translations_id';
protected $keyType = 'int';
public $incrementing = true;
public $timestamps = false;
public function country() {
return $this->belongsTo('country', 'translations_id', 'translations_id');
}
public function addresstype() {
return $this->belongsTo('addresstype', 'translations_id', 'translations_id');
}
}
The request "$entries = AB::all();" works in general but I get the id's and maybe I'm completely wrong here but I thought that data from foreign keys will be replaced with the respective models (if configured correctly). so my question is:
a. did I make a mistake during configuration and if yes, where exactly is the error?
or
b. is my assumption of replacing id's with objects is completly wrong?
Thanks in advance!

Laravel Eloquent models do not replace the foreign keys of the active records with the relational data, it only appends a new property with the same name as the method relating the classes and in that property it puts all the Model instances of the resulted query, this ONLY if you access the property, its called Eager Loading.
It is explained here (Ofiicial Documentation)
$addressBook = App\AddressBook::find(1); //this only will return the active record with the id 1 and nothig more.
$addressBook->country; // The property "country" does not exist in the AddressBook Classs but eloquent models will return a "fake" property with the value of the result of the query by the method with the same name (only if the method returns an Eloquent Relation).
This Eloquent behavior is natural, and is a very clever way to minimize the number of queries, Eloquent will never load a relation if there is no need to.
If you want to load a relation in a set the models at the same time that those models are retriving from the db you need to explicitly especify wich relations you want to load.
$addressBook = App\AddressBook::with(['country', 'addresstype', 'anotherRelation'])->get(); // this will retrive all the addressBook models and in each one will attach the relations specified.
[EDITED]
Also you have to place the entire namespace of the related model class in the relation methods so you need to replaced like:
class Translation extends Model
{
protected $table = 'translations';
protected $primaryKey = 'translations_id';
protected $keyType = 'int';
public $incrementing = true;
public $timestamps = false;
// ****** You need to put the entire namespace of the Model class
public function country() {
return $this->belongsTo('App\Country', 'translations_id', 'translations_id');
}

I'm new to laravel and just started creation of apis to connect to the database. I'm able to send a single entry at a time to the database, now what i want to do is to pass an array of data to be inserted into the database but don't seem to find my way around
Controller
public function newSaveUser(Request $request) {
$newFood = new Food;
$newFood->name = $request->name;
$newFood->save();
}
Model
namespace App;
use Illuminate\Database\Eloquent\Model;
class Food extends Model {
//
public $timestamps = false;
}
Try this here:
namespace App;
use Illuminate\Database\Eloquent\Model;
class Food extends Model
{
//
public $timestamps = false;
protected $fillable = ['name'];
}
and then to insert data:
Food::create([
'name' => $request->get('name')
]);
firstly check the db connection is works or not.
namespace App;
use Illuminate\Database\Eloquent\Model;
class Food extends Model
{
//
public $timestamps = false;
protected $table = "write_table_name_here";
protected $guarded = [];
}
extend model in controller;
$newFood = new Food;
$newFood->name = $request->name;
$newFood->save();
I have a model for custom fields,I want to bind the configuration detail for all model extended by Base model!
my CoctomFormBulder Model
class CustomFormBuilder extends \Eloquent
{
protected $fillable = [];
protected $table = 'custom_fields_configure';
}
Here is My base model and what I have try up to now.
class BaseModel extends \Eloquent {
protected $guarded = array('q');
protected $table = 'custom_fields_configure';
protected $appends = ['configure'];
public function getConfigerAttribute() {
if (isset($this->attributes['configure'])) {
//return URL::asset($this->attributes['image']);
return $this->attributes['configure'];
}
return '';
}
public function setConfigerAttribute($configure) {
$this->attributes['configure'] = $configure;
}
}
How can Bind Data from CustomFormBuilder to all of my models in the app
Just let the models that need that logic extends the 'CustomFormBuilder' class
I have the models
class User extends Model
{
protected $connection = 'mysql';
public function areas()
{
return $this->belongsToMany(Area::class, 'user_areas');
}
}
class Area extends Model
{
protected $connection = 'oracle';
}
the user_areas table is searched on oracle, but this are on mysql.
How I can indicate the connection for the pivot table?
I found this partial solution and it has worked
class User extends Model
{
protected $connection = 'mysql'
public function areas()
{
$instance = new Area;
$instance->setConnection('mysql');
return new BelongsToMany($instance->newQuery(), $this, 'user_areas', 'user_id', 'area_id', 'areas');
}
}
How do I go about using multiple Eloquent With()'s?
PortalPlaylistElement Model
class PortalPlaylistElement extends Model
{
public $primaryKey = 'code';
public $incrementing = false;
public $timestamps = false;
public function AirtimePlaylists()
{
return $this->hasOne('App\AirtimePlaylist','id','playlist_id');
}
}
AirtimePlaylistContent Model
class AirtimePlaylistContent extends Model
{
protected $table = 'cc_playlistcontents';
}
AirtimePlaylistModel
class AirtimePlaylist extends Model
{
protected $table = 'cc_playlist';
public function PortalPlaylistElements()
{
return $this->belongsTo('App\PortalPlaylistElement','playlist_id');
}
public function AirtimePlaylistContents()
{
return $this->hasMany('App\AirtimePlaylistContent','playlist_id');
}
}
I have no problems with:
AirtimePlaylist::with('AirtimePlaylistContents')->get());
or
PortalPlaylistElement::with('AirtimePlaylists')->get();
But I'd like to get all AirtimePlaylistContents, in an AirtimePlaylist that belongs to a PortalPlaylistElement.
In essence, (Pseudo code)
PortalPlaylistElement::with('AirtimePlaylists')::with('AirtimePlaylistContents')->get();
You need Nested Eager Looading
PortalPlaylistElement::with('AirtimePlaylists.AirtimePlaylistContents')->get();
nested relations
with('relation1.relation2.relation3')->get(); // relation1 has relation2 relation2 has relation 3
not nested relations
with('relation1','relation2','relation3')->get(); // you model has all relations
I would like to add this if someone needed it
with(['relation1.relation2-1','relation1.relation2-2'])->get(); // relation1 has relation2-1 and relation1 also has relation2-2
I'm attempting to seek a table to see if a column named "name" exists if so return the value and if not create that row with a null value i saw firstOrCreate but i cannot figure out how to use it for the life of me.
This is what i currently have, can someone lend a hand?
class Settings extends Eloquent
{
protected $table = 'settings';
protected $primaryKey = 'name';
public static function get($settingName)
{
return self::firstOrCreate(array('name' => $settingName));
// return self::select(array('value'))->where('name', '=', $settingName)->first()->value;
}
}
The create() method does mass assignment and this is a big security issue, so Laravel has a protection against it. Internally it has guarded = ['*'], so all your columns will be protected against mass assignment. You have some options:
Set the fillable columns of your model:
class User extends Eloquent {
protected $fillable = array('first_name', 'last_name', 'email');
}
Or set only the ones you want to keep guarded:
class User extends Eloquent {
protected $guarded = array('password');
}
You may, at your own risk also do:
class User extends Eloquent {
protected $guarded = array();
}
And everything will be unguarded.
Take a look a the docs: http://laravel.com/docs/eloquent#mass-assignment
You also could use your Facade to call it:
class Settings extends Eloquent
{
protected $table = 'settings';
protected $primaryKey = 'name';
public static function get($settingName)
{
return Settings::firstOrCreate(array('name' => $settingName));
}
}
