I have 4 tables:
conversations
- id (pk)
- userId1 (fk)
- userId2 (fk)
users
- id (pk)
- name
- surname
.
.
.
- roleId (fk)
- userStatusId (fk)
roles
- id (pk)
- type (fk)
user_status
- id (pk)
- description (fk)
this are my models:
class Conversation extends Eloquent {
public function user1(){
return $this->hasOne('User', 'id', 'userId1');
}
public function user2(){
return $this->hasOne('User', 'id', 'userId2');
}
}
class User extends Eloquent {
public function role(){
return $this->hasOne('Role', 'id', 'roleId');
}
public function userStatus(){
return $this->hasOne('UserStatus', 'id', 'userStatusId');
}
// public function conversation1(){
// return $this->belongsToMany('Conversation', 'id', 'userId1');
// }
// public function conversation2(){
// return $this->belongsToMany('Conversation', 'id', 'userId2');
// }
}
class UserStatus extends Eloquent {
public $timestamps = false;
protected $table = 'user_status';
public function user(){
return $this->belongsToMany('User', 'id', 'userStatusId');
}
}
class Role extends Eloquent {
public $timestamps = false;
public function user(){
return $this->belongsToMany('User', 'id', 'roleId');
}
}
Now what I want to do is, for example, take all the conversations where the "userId1" (on conversations) is of a "user" who have the status "description" equal to "registered".
That's what I do:
Route::get('/', function(){
$conversation = Conversation::with(array('user1.userStatus' => function ($query){
$query->where('description', '=', 'registered');
}))->get();
foreach ($conversation as $conv) {
echo '<br \>';
echo $conv;
}
});
I expect to receive all the conversations record where the status of the userId1 is "registered" and nothing else... Instead what I receive are all the conversations records and, for each one, the user records and the records of the userStatus table (of this last I receive just the one who match the where clause and the ones who are not have a null value).
I know my english is terrible but I hope someone could understand and help me. Thanks!
All your relations are wrong. You need to read http://laravel.com/docs/eloquent#relationships and in your case it's:
class Conversation extends Eloquent {
public function user1(){
return $this->belongsTo('User', 'userId1');
}
public function user2(){
return $this->belongsTo('User', 'userId2');
}
}
class User extends Eloquent {
public function role(){
return $this->belongsTo('Role', 'roleId');
}
public function userStatus(){
return $this->belongsTo('UserStatus', 'userStatusId');
}
}
class UserStatus extends Eloquent {
public $timestamps = false;
protected $table = 'user_status';
public function user(){
return $this->hasMany('User', 'userStatusId');
}
}
class Role extends Eloquent {
public $timestamps = false;
public function user(){
return $this->hasMany('User', 'roleId');
}
}
Now, to retrieve only those conversations you want this:
Conversation::whereHas('user1', function ($q) {
$q->whereHas('userStatus', function ($q) {
$q->where('description', 'registered');
});
})->get();
or using this PR https://github.com/laravel/framework/pull/4954
Conversation::whereHas('user1.userStatus', function ($q) {
$q->where('description', 'registered');
})->get();
Also, to make it more verbose, you can wrap that code in a scope:
// User model
public function scopeRegistered($query)
{
$q->whereHas('userStatus', function ($q) {
$q->where('description', 'registered');
});
}
then:
Conversation::whereHas('user1', function ($q) {
$q->registered();
})->get();
You may try this:
$conversations = Conversation::whereHas('user1.userStatus', function ($query){
$query->where('description', '=', 'registered');
})->get();
This will return only the Conversation models whose related user1.userStatus is registered.

I am working on a survey system and I have a problem accessing one relationship through another.
I have these models and these relationships

I need to do a query with eadger loading to bring me all the posts with survey, surveyOptions, withCount comments y options_values of each surveyOptions. Something like this:
$post->survey->surveyOptions->options_values_count
I have managed to create this query that works for me everything except fetching the option_values count from each SurveyOption. How can I do it?
$posts = Post::with([
'survey' => function ($query) {
$query->withCount('totalSurveys');
},
'survey.surveyOptions',
'image',
'categories'
])
->withCount('comments')
->get();
i have a user(ADMIN) and a student i want them to be in one table that is on the dashboard controller i cant find and exact answer in the searching please help me
Student model
public function user()
{
return $this->belongsTo("App\User", 'User_id', 'id');
}
User model
public function student()
{
return $this->hasMany("App\Student");
}
DashboardController
$users = User::with('user_id');
return view('superadminpage.admin_table')->with('users', $users);
Edit Student model code like this:
public function user(){
return $this->belongsTo("App\User");
}
Also edit User model:
public function students(){
return $this->hasMany("App\Student");
}
then use in DashboardController
$users = User::query()->with("students")->all();
return view('superadminpage.admin_table')->with('users', $users );
then you can do this:
foreach($users as $user){
$students = $user->students;
// use
}
first change the User_id to user_id at student model
public function user()
{
return $this->belongsTo("App\User", 'user_id');
}
second change at DashboardController
$users = User::with('user_id'); to $users = User::with('student')->all();
first change the User_id to user_id at student model
public function user()
{
return $this->belongsTo("App\User", 'user_id' , 'id');
}
second change at DashboardController
$users = User::with('user_id'); to $users = User::with('student')->all();
it's also good to change at user model public function student() to public function students() and call at DashboardController $users = User::with('students')->all();
public function users()
{
return $this->hasMany('App\User');
}
public function role()
{
return $this->belongsTo('App\Role');
}
I have the following models using Laravel 5.3:
Provider:
// Provider model
$primaryKey = 'id'
public function activities()
{
return $this->hasMany(Activity::class);
}
Activity:
// Activity model
$primaryKey = 'id'
public function provider()
{
return $this-belongsTo(Provider::class);
}
public function semesters()
{
return $this->hasMany(Semester::class);
}
public function semesterPurchases()
{
return $this->hasManyThrough(Purchase::class, Semester::class, 'activity_id', 'purchasable_id')
->where('purchasable_type', Semester::class);
}
Semester:
// Semester model
$primaryKey = 'id'
public function activity()
{
return $this->belongsTo(\App\Models\Activity::class, 'activity_id', 'id');
}
Purchase:
// Purchase model
$primaryKey = 'id'
public function purchasable()
{
return $this->morphTo();
}
In my case Semester::class is the purchasable_type. Is there a way to establish a relationship between Provider::class and Purchase::class? In order to make it possible to do something like this:
$providers = Provider::select('id', 'name', 'address')
->with('purchases')
->where('providers.id', 1)
->get();
I would prefer not to go through activities like so:
$providers = Provider::select('id', 'name', 'address')
->with('activities.purchases')
->where('providers.id', 1)
->get();
which I know I can do using hasManyThrough on the Activity::class
Laravel has no native support for a direct relationship.
I've created a package for cases like this: https://github.com/staudenmeir/eloquent-has-many-deep
class Provider extends Model
{
use \Staudenmeir\EloquentHasManyDeep\HasRelationships;
public function purchases()
{
return $this->hasManyDeep(
Purchase::class,
[Activity::class, Semester::class],
[null, null, ['purchasable_type', 'purchasable_id']]
);
}
}
Provider::find($id)->purchases;
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
use Laravel\Scout\Searchable;
class Event extends Model
{
protected $table = 'events';
public $timestamps = true;
use Searchable;
use SoftDeletes;
protected $dates = ['deleted_at'];
public function entities()
{
return $this->belongsTo('App\Entity', 'entity_id');
}
public function users()
{
return $this->belongsTo('App\User', 'id');
}
public function events()
{
return $this->belongsTo('App\DirtyEvent', 'id');
}
public function toSearchableArray()
{
$data = $this->toArray();
$data['entities'] = $this->entities->toArray();
return $data;
}
}
This is my model for Event, as you can see I am using toSearchableArray which is Laravel scout function to import 'relations' to algolia. However the problem is that sometimes it is empty. So for example
event id 1 has entity_id 1
but in another example
event id 2 has entity_id = null
How can I modify this function to check if the entities() relation is not empty before putting it into array?
if i understand u correctly this should help. if the relationship does not exist return an empty array and scout won't update the index
public function toSearchableArray()
{
if(is_null($this->entities)){
return [];
}
$this->entities
return $this->toArray();
}
please update foreign_key in relation as this
user_id as foreign_key instead of id
event_id as foreign_key instead of id
public function users()
{
return $this->belongsTo('App\User', 'user_id');
}
public function events()
{
return $this->belongsTo('App\DirtyEvent', 'event_id');
}
I think if load the relation before the toArray().
public function toSearchableArray()
{
$this->entities;
return $this->toArray();
}
I'm using Laravel 4. I have the following models:
class User extends Eloquent {
protected $table = 'users';
public function questions()
{
return $this->hasMany('UserQuestion', 'user_id', 'user_id');
}
}
class UserQuestion extends Eloquent {
protected $table = 'user_questions';
public function user()
{
return $this->belongsTo('User', 'user_id', 'user_id');
}
public function subquestions()
{
return $this->hasMany('UserSubquestion', 'question_id', 'id');
}
}
class UserSubquestion extends Eloquent {
protected $table = 'user_subquestions';
public function question()
{
return $this->belongsTo('UserQuestion', 'question_id');
}
public function answers()
{
return $this->hasMany('UserAnswer', 'subquestion_id', 'id');
}
}
class UserAnswer extends Eloquent {
protected $table = 'user_answers';
public function subquestion()
{
return $this->belongsTo('UserSubquestion', 'subquestion_id');
}
}
I have the following query:
$results = User::with(['questions' => function($query) {
$query->where('status', '1');
$query->where('category', 'medicine');
}])
->with('questions.subquestions', 'questions.subquestions.answers')
->get();
However, the where conditions I'm applying to the questions relationship aren't being applied to the joined tables (subquestions and answers).
How can I make the conditions apply to them as well?
Note: The values of status and category in the conditions are dynamic (i.e. won't always be 1 or medicine).
Try doing your call like this instead:
$results = User::with(['questions' => function($query) {
$query->where('status', '1');
$query->where('category', 'medicine');
},
'questions.subquestions',
'questions.subquestions.answers'
])->get();
Note, this time the method with is only called once.
