I'm beginning to use Laravel Model relationship. But now I don't know how to used that relationship as below function
class Notification extends Model{
public function getNotification() {
return self::select('*')->join('users','users.id','=','Notification.n_user_id')->get();
}
}
Try this:
class User extends Model
{
/**
* Get the Notifications for the User.
*/
public function notifications()
{
return $this->hasMany('App\Notification');
}
}
But I see in your code that the foreign key field of User ID is named n_user_id you should changed it to user_id to link them
How to use:
$notifications = App\Post::find(1)->notifications;
foreach ($notifications as $notification) {
//
}
here is a useful Link in Laravel 5.2 Docs
Bonus:
You can also get the User of the notification:
class Notification extends Model
{
/**
* Get the User that owns the Notification.
*/
public function user()
{
return $this->belongsTo('App\User');
}
}
I have used the following way and hope it'd be helpful.
public function getNotification() {
$data = DB::table('users')
->join('Notification', 'users.id', '=', 'Notification.n_user_id')
->select('users.*', 'Notification.*')
->where('users.id', '=', 5)
->get();
return $data;
}

Hello I have the following relationship setup:
Product class:
public function attributes()
{
return $this->hasMany(ProductAttribute::class);
}
ProductAttribute class:
public function attribute()
{
return $this->belongsTo(Attribute::class);
}
public function values()
{
return $this->hasMany(ProductAttributeValue::class, 'product_attribute_id');
}
ProductAttributeValue class:
public function attributeValue()
{
return $this->belongsTo(AttributeValue::class, 'attribute_value_id');
}
How to check if Product has values with ids 5 and 15?
I am trying to make a query like this:
Product::whereHas('values', function($q) use ($product_values_ids) {
$q->whereIn('attribute_value_id', $product_values_ids);
})->get();
however it is not working. I cannot access directly $product->values.
Any suggestions on how to access directly the values of attributes from the Product?
Update:
I have just managed to make it work with a many to many trough relationship:
Product class:
public function values()
{
return $this->hasManyThrough(ProductAttributeValue::class, ProductAttribute::class);
}
is there a way to get only the results that have all the ids listed in the $product_values_ids array?
You have to add new relation to Product model:
public function values(): HasManyThrough
{
return $this->hasManyThrough(ProductAttributeValue::class, ProductAttribute::class);
}
and then:
$builder = Product::query();
foreach($product_values_ids as $id) {
$builder->whereHas('values', function($q) use ($id) {
$q->where('id', $id);
});
}
$product = $builder->get();
I am using Laravel 5.2 and I need to get specific values from the database with a leftjoin. The code I am using is as follow:
public function commentList(Request $request)
{
$inputs = $request->all();
$commentList = Comment::select(
'projects_comments.id as comment_id',
'u.name as user_name',
'projects_comments.comment as comment',
'projects_comments.created_at as created_at'
);
$commentList->leftjoin('users AS u', 'projects_comments.user_id', '=', 'u.id');
if (!empty($inputs['project_ids'])) {
$commentList->where(function ($query) use ($inputs) {
foreach ($inputs['project_ids'] as $i) {
$query->orWhere('projects_comments.project_id', $i);
}
});
};
$data = $commentList->get();
return $data;
}
It works fine but I would like to know if there is a better way to do this using eloquent but I can't really understand how to write this for eloquent to work. I need to get all the comments from an array of project ids.
I have the following model for Comment:
class Comment extends Model
{
protected $table = 'projects_comments';
public $timestamps = true;
protected $guarded = ['id'];
public function project()
{
return $this->belongsTo('App\Project', 'project_id');
}
public function user()
{
return $this->belongsTo('App\User', 'user_id');
}
}
I assume what you want is to get Comments (with their users) that belongs to specific Projects provided by the user as an array of IDS
Comment::whereIn('project_id', $inputs['project_ids'])->with('user')->get();
And if you only want the id and name of the user associated with the comment, pass the fields to the with function like so
Comment::whereIn('project_id', $inputs['project_ids'])
->with('user:id,name')->get();
I'm using laravel
I have two models
Product
class Product extends Model
{
public function productcategories(){
return $this->hasOne('App\Product\Productcategorie','CategoryID','ProductCategoryId');
}
}
and Productcategorie
class Productcategorie extends Model
{
protected $primaryKey = 'CategoryID';
public function product(){
return $this->belongsToMany('App\Product\Product','ProductCategoryId','CategoryID');
}
public function scopeCp($query,$id){
return $query->where('categoryparent_id', '=', $id);
}
}
The Product model has a scope Cpscope
and i have ProductController with function
function productCatgoryPaFilter(Request $request){
$categories= Categoryparent::with('categories')->get();
$id=$request->id;
return $product = Product::with('productcategories')->with('productoption.option')->orderBy('created_at','DESC')->get();
}
i want to get all products with categoryparent_id equal to passed parametre in scope
how can i do it?
If you want to filter data in relational model, use whereHas(). Though i have not tested, give it a try
Product::whereHas('productcategories', function ($query) use($id) {
$query->cp($id);
})
->orderBy('created_at','DESC')->get()
I have this two queries to display information in 3 tables Users, Comments, and Posts. so I made this function:
public function show($id)
{
$posts = Post::with(['comments'])->findOrFail($id);
$user = User::find($posts->user_id);
echo "<h1>".$posts->title.'</h1>';
echo "<h2>".$user->name.'</h2>';
foreach ($posts->comments as $comment) {
echo $comment->body.'<br>';
}
}
on this function I using two variable $posts and $user, can I merge this two variable using eloquests command like Post::with(['user','comments'])'? so I can use just $posts variable and use it like $posts->users->name to access user name.
i was trying using this way:
$posts = Post::with(['comments','users'])->findOrFail($id);
but when i echo the post it showing that the user was null:
{"id":1,"user_id":1,"title":"Oleh id 1","body":"ini adalah content","created_at":"2017-10-18 03:25:54","updated_at":"2017-10-18 03:25:54","comments":[{"id":1,"post_id":1,"body":"Keren banget deh artikelnya, TOP","created_at":"2017-10-18 03:43:50","updated_at":"2017-10-18 03:43:50"},{"id":2,"post_id":1,"body":"Keren banget deh artikelnya, TOP","created_at":"2017-10-18 03:43:53","updated_at":"2017-10-18 03:43:53"},{"id":3,"post_id":1,"body":"Keren banget deh artikelnya, TOP","created_at":"2017-10-18 03:43:54","updated_at":"2017-10-18 03:43:54"}],"users":null}
Here's my model if you need it. My post model:
class Post extends Model
{
/**
* Get the comments for the blog post.
*/
public function comments()
{
return $this->hasMany('App\Comment');
}
public function users(){
return $this->belongsTo('App\User');
}
}
my Comment model
class Comment extends Model
{
/**
* Get the post that owns the comment.
*/
public function post()
{
return $this->belongsTo('App\Post');
}
}
You’ll have an easier time sticking to Laravel’s conventions for naming relationships.
A Post has many Comments, which belong to a User. Given this set up:
class Post extends Model
{
public function comments()
{
return $this->hasMany(Comment::class);
}
}
class Comment extends Model
{
public function post()
{
return $this->belongsTo(Post::class);
}
public function user()
{
return $this->belongsTo(User::class);
}
}
You can then query a post’s comments and users like this:
$comments = $post->comments()->with('user')->get();
You could also eager-load the user relation on comments if you always wanted the user returned with a comment:
class Comment extends Model
{
protected $with = ['user'];
public function user()
{
return $this->belongsTo(User::class);
}
}
Then your query would be simplified:
$comments = $post->comments;
Hope this helps you!!
What I am guessing is you want the list of all posts with the users. If relation is defined, try with the join
$posts = DB::table('posts')
->join('users', 'users.id', '=', 'posts.user_id')
->select('posts.*', 'users.name as user_name')
->where('posts.comments', '<>', NULL)
->get();
#NOTE: If you are using soft deletes you might wanna add where('posts.deleted_at', null)
After couple of days searching finally i got the answer, i can get merge the query like this:
$posts = Post::with(['comments','users'])->findOrFail($id);
but in the Post Model the function not "Users" but "User".
My data model is this:
Users > Offices > Organization
This is my model
class Organization extends Model {
protected $table = 'organizations';
public function offices()
{
return $this->hasMany('App\Models\Office');
}
public function users()
{
return $this->offices()->users();
}
....
So.. I want to get all users from an organization (of all the offices).
But I don't know how to do something like
$this->offices()->users();
(Avoiding user a manual collection or map to do that)
Thanks!
So, you have organization ID. You can load all users by using whereHas():
$users = User::whereHas('office', function ($q) use ($organizationId) {
$q->where('organization_id', $organizationId);
})
->get();
Make sure office() relationship is defined correctly in User model:
public function office()
{
return $this->belongsTo('App\Office');
}
Alternatively, you could define hasManyThrough() relationship:
public function users()
{
return $this->hasManyThrough('App\Office', 'App\User');
}
And use it:
$organization->users()
