I have a Client model that hasMany Appointment models. And an Appointment belongs to a Client. I am trying to return results that show me the client's name as well as their list of appointments on an index blade. Here is my code so far:
Client Model
public function appointment()
{
return $this->hasMany(Appointment::class);
}
Appointment Model
public function client()
{
return $this->belongsTo(Client::class);
}
Controlller
$clients = Client::with('appointment')->get();
//dd($clients);
return view('scheduler')->withclients($clients);
Blade
#foreach($clients as $client
{{ $client->name }}
{{ $client->appointment->id }}
#endforeach
How can I print $client name and their list of appointments? I have tried other help regarding this issue but I am not clear where I am going wrong.
So you relationship is a One-To-Many relationship. You have a lot of appointments then.
You can iterate over the clients list first and in the inner loop over the appointments:
#foreach($clients as $client)
{{ $client->name }}
#foreach($clients->appointment as $appointment)
{{ $appointment->id }}
{{ $appointment->name }}
#endforeach
#endforeach
Anyway, it might be easier to go over the appointment model, because it's in relation to exactly one client:
#foreach(Appointment::all() as $appointment)
{{ $appointment->name }}
{{ $appointment->client->name }}
#endforeach

I am displaying a list on my blade view which contains data from the display table: name, school and IP.
The school is saved as a school id in this table.
The Schools table contains the list of ids and related schools.
I want to use the school names from the schools table and display them on my blade view.
I can get this data separately.
This gets all the data from the display table
$records = DB::table('display')->paginate(10);
This gets all the school name from the schools table.
$schools = DB::table('schools')
->join('display', 'schools.id', '=', 'display.school')
->select('schools.name')
->get();
To display the data from the display table I'm using a foreach loop.
#foreach ($records as $record)
{{ $record->name }}
{{ $record->school }}
{{ $record->ip }}
#endforeach
I don't know how to insert the school name into the space where currently $record->school appears. $record->school displays the school ID, but I want to display the school name which is saved in the school table.
Display model
public function school()
{
return $this->belongsTo('App\School');
}
School model
public function display()
{
return $this->hasMany('App\Display');
}
If you have models and Eloquent relations, you can simply use it:
Controller
$records = Display::with('school')->paginate(10);
Blade view
#foreach ($records as $record)
{{ $record->name }}
{{ $record->school->name }} <!-- school name via relation -->
{{ $record->ip }}
#endforeach
Display Model
class Display extends Model
{
public function school()
{
return $this->hasOne('App\School');
}
}
You really should be using Eloquent as it makes life so much easier. However, using DB, you need code similar to below, where you are joining schools as a relationship to display.
$records = DB::table('display')
->join('schools', 'schools.id', '=', 'display.school')
->paginate(10);
#foreach ($records as $record)
{{ $record->name }}
{{ $record->schools->name }}
{{ $record->ip }}
#endforeach
Goods Model
class goods extends Model
{
protected $table = "goods";
public function sales(){
return $this->belongsToMany('App\sales', 'sales_details', 'goods', 'sales');
}
}
Sales Model
class sales extends Model
{
protected $table = "sales";
public function goods(){
return $this->belongsToMany('App\goods','sales_details','sales','goods');
}
}
i also make this model but i don't know if i ever need it or not
class salesDetail extends Model
{
protected $table = "sales_details";
}
my controller
public function test()
{
$goods = goods::all();
return view('test',compact('goods'));
}
my test.blade.php
#foreach($goods as $data)
<li><strong>{{ $data->name }}</strong> - {{ $data->company->kind }} {{ $data->company->name }}</li>
<p>{{ $goods->sales }}</p>
#endforeach
i connect goods table with sales table with many to many without following laravel naming.
This is my table contents
goods
-id
-name
sales
-id
-date
sales_details
-goods
-sales
-qty
-price
and i couldn't make it work. i just wanted to show the result like this
sales -id
sales - date
goods - name
sales_details - qty
sales_details - price
this should be the result
In your #foreach loop you're trying to access sales on the collection of goods rather than the instance in the loop. Also, because the sales() relationship is a belongsToMany (many-to-many) you're going to get a collection and not a single instance so you're going to need to loop through them as well e.g.
#foreach($goods as $data)
<li>
<strong>{{ $data->name }}</strong> - {{ $data->company->kind }} {{ $data->company->name }}
#foreach($data->sales as $sale)
<p>{{ $sale->date }} - {{ $sale->pivot->qty }}</p>
#endforeach
</li>
#endforeach
To access data from your pivot table you will first need to tell Laravel to include that information in the relationship:
public function sales()
{
return $this->belongsToMany('App\sales', 'sales_details', 'goods', 'sales')
->withPivot('qty', 'price');
}
You should also add the withPivot method to the good() relationship in the sales class as well.
Then you'll be able access the information from the pivot property. This is happening in the example above with {{ $sale->pivot->qty }}.

I have two tables ..
User and UserMeta
I made relationship between them with hasOne().
Model
public function user_meta() {
return $this->hasOne('App\UserMeta');
}
Controller
public function index() {
$users = User::orderBy('id', 'desc')->paginate(10);
return view('users.index')->with('users', $users);
}
View
#forelse ($users as $user)
{{ $user->user_meta->country }}
#empty
#endforelse
This return error
Trying to get property 'country' of non-object
But here if I use dd() like this.
#forelse ($users as $user)
{{ dd($user->user_meta->country) }}
#empty
#endforelse
I can see the value return correctly. United State
dd stop loop execution for first element. If you uses dump helper, you will see this error again after several iterations. You need check for null:
#forelse ($users as $user)
#if(!is_null($user->user_meta))
{{ $user->user_meta->country }}
#endif
#empty
#endforelse
I'm trying to figure out how to get all the posts for a category using Laravel Eloquent 5.3.
I have three tables..
**Posts**
id | title | text
**Term_relationships**
term_id | post_id
**Terms**
id | name
Eloquent Models
class Term extends Model
{
public function posts()
{
return $this->belongsToMany('App\Post', 'term_relationship');
}
}
class Post extends Model
{
public function terms()
{
return $this->belongsToMany('App\Term', 'term_relationship');
}
}
class Term_relationship extends Model
{
}
I've tried with for example
Term::where('name', $category)->posts->get();
Easy,
if you want Posts with Terms do this
$data = App\Post::with('terms')->get();
in your view :
#foreach($data as $post) // will loop over posts and show title
<div>{{$post->title }} </div>
#foreach($post->terms as $term)
<div> {{ $term->title }} </div> // will loop and echo all terms for current post
#endforeach
#endforeach
if you want Terms with posts do this
$data = App\Term::with('posts')->where('name', $category)->get();
in your view
#foreach($data as $term) // will loop over terms and show title
<div>{{$term->title }} </div>
#foreach($term->posts as $post)
<div> {{ $post->title }} </div> // will loop and show all posts in each term
#endforeach
#endforeach
i think the seconds way suits your needs better since int he first example u will need to use wherehas and a closure
I'm trying to access a relations table from a collection of data passed in from the controller. I am able to iterate the collection in my view but I am unable to access the relationship data.
There are 2 tables:
stocks (default model)
stock_datas (has a foreign key stock_id which is already setup)
Controller:
public function getstock() {
return view('vehicles.getstock', ['stock' => \App\Stock::all()]);
}
Model (App\Stock) and then (App\StockData)
// From stock model:
public function stockdata() {
return $this->hasOne('App\StockData');
}
// Stock Data model:
public function stock() {
return $this->belongsTo('App\Stock');
}
View (loop):
#foreach ($stock as $k => $v)
{{ print_r($v->stockdata()->get())->year }}
#endforeach
When I try the query below, I get a
Undefined property: Illuminate\Database\Eloquent\Collection::$year (View: F:\websites\tempsite\resources\views\vehicles\getstock.blade.php)
However, year is a column in the stock_datas table.
I am also able to print_r data from the \App\StockData() table so the reference to the table is correct as doing print_r(\App\StockData::all()) from the controller does return all the rows as expected.
What am I doing wrong?
Since it's one to one relation, you should do it like this:
#foreach ($stock as $v)
{{ $v->stockdata->year }}
#endforeach
First one You have to change {{ print_r($v->stockdata()->get())->year }} this line, remove print_r. Next one in foreach loop you can do something like this
#foreach($stock as $one)
{{ $one->stockadata()->first()->year }}
#endforeach
For better solution you should check if isset $one->stockadata()->first()
and after that call ->year. Finally code should be like this
#foreach($stock as $one)
{{ isset($one->stockadata()->first()) : $one->stockadata()->first()->year : 'Default' }}
#endforeach
When calling get() method on any relationship You will always receive collection, no matter what relationship You have.
There are at least two (2) ways to solve Your problem:
1. $v->stockdata->year
2. $v->stockdata()->first()->year
I would suggest You to use first one, because Your stockdata has 1:1 relationship.
Good luck!
For example:
Stock.php model
class Stock extends Model
{
protected $primaryKey = 'id';
function stockdata() {
return $this->hasOne('App\StockDatas', 'id', 'stock_id');
}
public function getStock(){
return Stock::with('stockdata')->get();
}
}
In contriller
public function getstock(Stock $stock) {
return view('vehicles.getstock', ['stock' => $stock->getStock]);
}
view
#foreach ($stock as $k => $v)
{{ $v->stockdata->year }}
#endforeach
