I have two table email (email_id, email) and users (user_id) with a pivot table user_email (id, user_id, email_id) and i would like to check the existence of my email "toto#toto.com" for my user_id "2".
$emailID = Email::where('email', 'toto#toto.com')->pluck('id');
$exists = User::find('2')->emails->contains($emailID);
The result is ok, but i would like to know if it's possible to combine this into one query using Eloquent.
If have these models :
class Email extends Model {
public function users() {
return $this->belongsToMany('App\User', 'user_email');
}
}
class User extends Model {
public function emails() {
return $this->belongsToMany('App\Email', 'user_email');
}
}
You can make query with relationships too:
$email_address = 'toto#toto.com';
$user_id = 2;
$email = Email::whereHas('users', function($q) use ($user_id) {
$q->where('users.id', $user_id);
})->where('email', $email_address)->first();
if($email->exists) {
//... it exists
}
Yes, you can do it like this.
public function getUserById($id) {
$user = User::with('emails')->where('id', 2)->first();
return view('your-view')->with('user', $user);
}
Then on your blade template.
#foreach ($user->emails as $email)
{{ $email->email }}<br/>
#endforeach

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 = $builder->get();
How to List all rows from a table (agendas) in my DB where records are saved by the connected user.I'm using default Auth from Laravel.
public function index ($id = null)
{
$agendas = Agenda::where('id', Auth::user()->id)->get();
$users = User::all();
return view('admin.agendas.index', compact('agendas','users','id'));
}
My controller here.
Need help
Assuming
agendas table (containing records for Agenda model) has a column user_id which references the id column on users table
User hasMany Agenda
Agenda belongTo User
class User extends Model
{
public function agendas()
{
return $this->hasMany(Agenda::class);
}
//... rest of class code
}
class Agenda extends Model
{
public function user()
{
return $this->belongsTo(User::class);
}
//... rest of class code
}
public function index($id = null)
{
$user = User::with('agendas')->findOrFail(auth()->id());
return view('admin.agendas.index', [
'user' => $user,
'agendas' => $user->agendas,
'id' => $id
]);
}
Your User model should have a relationship:
public function agendas()
{
return $this->hasMany(Agenda::class);
}
In your controller, you could then simplify the use as such:
public function index (Request $request, $id = null)
{
$agendas = $request->user()->agendas;
$users = User::all();
return view('admin.agendas.index', compact('agendas','users','id'));
}
if you wanna get data related to another data , you have to join those tables together by a field. in this case i guess you have a column in Agenda table named 'user_id'.
you have two way :
join tables in your Model.
search in Agenda table in your controller
if you want to use joining your tables from model :
// in App\User.php
...
class User ...{
...
public function Agenda(){
return $this->hasMany(Agenda::class);
}
...
}
...
then you can access to all of "Agenda" from everywhere like this :
Auth()->user()->agenda
if you want to search in table from your controller you can do :
Agenda::where('id', Auth::user()->id)

Hi I am trying to create a record base from ID of an order transaction.
I have here the ORDERS, CAMPANIES and CURRENCIES models.
Now I want the ORDER to get the ID from a URL Parameter, and then the companies should grab the company_id from Orders same with currency, I want to grab the currency_id from orders.
Here's what I came up so far:
public function create($order_id)
{
$order = Orders::find($order_id)->where('id', '=', $order_id)->get();
$company = Companies::where('id', '=', $order['company_id'])->get();
$currency = Currencies::where('id', '=', $order['company_id'])->get();
$banks = Banks::all('name','acronym','id')->get();
return view('orderPayments.create', compact('order'))
->with('company', $company)
->with('currency', $currency)
->with('banks', $banks);
}
currencies model
public function orderPayments()
{
return $this->hasMany('App\Orderpayments', 'id','currency_id');
}
Companies Model
public function orderPayments()
{
return $this->hasMany('App\Orderpayments', 'id','company_id');
}
Order Payments Model
public function company()
{
return $this->hasOne('App\Companies', 'id','company_id');
}
public function currency()
{
return $this->hasOne('App\Currencies', 'id', 'currency_id');
}
public function bank()
{
return $this->hasOne('App\Bank', 'id', 'currency_id');
}
How can I achieve it? thank you so much in advance!
UPDATE
I just applied #sandy's answer. I checked if the $order has a content so I echod the $order by doing this, {{ $order }} The return value is ok.
but when I calling the other attributes like $order->grandtotal, or $order->companies->comp_name the error is
If your relationship between your models is a One To Many relationship you should use belongsTo in your relations like this:
OrderPayment Model
public function company()
{
return $this->belongsTo('App\Companies','company_id');
}
public function currency()
{
return $this->belongsTo('App\Currencies','currency_id');
}
public function bank()
{
return $this->belongsTo('App\Bank', 'currency_id');
}
Also, the second parameter on the function should be your foreign key.
Answering your question:
If you want to access the relations of a given Order you could do this:
$order = Order::find($order_id);
$order->company; // this will return the company
$order->currency; // this will return the currency
If you want to display in your view:
{{$order->company->anyCompanyAttribute}}
Note:
You should name your models in SINGULAR like Currency, Company. Not in plural.
try like this
$order = Orders::with(['company','currency'])->where('id', '=', $order_id)->get();
I have this two queries to display information in 3 tables Users, Comments, and Posts. so I made this function:
public function show($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".
Let's say I have User Model. Each User has Pet model.
both have relationship setup correctly.
When I get the user data along with his pets, I do this:
return $this->with('pets');
but what if I want to return the pet name only with the user data?
I've been trying that:
return $this->with('pets.name');
Didn't work for me.
Model
Class User extends Model ()
{
...
public function pets()
{
return $this->hasOne('App\Model\Pet');
}
}
Controller or Repository or any other object
function getUserDetails (Request $request)
{
$userId = $request->get('id');
$findUserById = User::find($userId);
$fullName = $findUserById->pets->fullname;
}
You can do this way :
$users_with_pet_name = DB::table('users')
->join('pets', 'users.id', '=', 'pets.user_id')
->select('users.*', 'pets.name')
->get();
