How can I add pagination to model relation in my controller? Here's my case :
public function show($movie) {
$movie = Movie::find($movie);
$episodes = $movie->episodes;
$genre = $movie->genre;
return view('layout.detailMovie', compact('movie', 'episodes', 'genre'));
}
I want to add pagination for the $episodes. Where do I have to put the "->paginate()" code?
public function show($movie) {
$movies = Movie::with('episodes', 'genre')->where('movie', $movie)->paginate(3);
return view('layout.detailMovie', compact('movies'));
}
In Blade
{{ $products->links() }} OR {{ $products->render() }}
You can fetch data in blade like
foreach($movies as $movie) {}
//your code
}
foreach($movies->episodes as $episodes) {}
//your code
}
foreach($movies->genre as $genre) {}
//your code
}
try this :
Movie::find($movie)->with('episodes')->paginate(3);
or:
$reports = User::find($user->id)
->reports()
->orderBy('created_at', 'DESC')
->paginate($paginate);
return $reports;
if that doesnt work look at this :
How to paginate a "has many" relationship that is ordered?

Comparing to tables in Laravel. I have this code in my class (model):
public function table1() {
return $this->hasOne(table1Class::class, 'type', 'bms_id');
}
public function table2() {
return $this->belongsTo(table2Class::class, 'bms_id', 'type');
}
The controller, has something like this:
$type =
DB::table('table2')
->join('table1', 'table1.col_id','table1.col_name')
->select('table2.*', 'table1.*')
->get();
$dataMerge = $dataMerge->merge($type);
In the view, I have:
#foreach($data as $item)
{{$item->type==120}} //this works, no problem
{{$item->col_name}} //this produces nothing!
#endforeach
As you can see, the code stops working when referencing the col_name, any suggestions?
Thanks in advance!
I have set up a many to many relationship in Laravel and have the database table populated with data. The relationship setup looks like this...
users.php
---------
public function houses()
{
return $this->belongsToMany('App\House')
->withTimestamps();
}
house.php
---------
public function users()
{
return $this->belongsToMany('App\User')
->withTimestamps();
}
In my /house/show.blade.php I am trying to display the saved connections like this...
$houses = House::with('App\User')->all();
foreach ($houses as $house) {
echo 'Found House';
}
It is giving me an error saying that $houses can not be found. Where am I going wrong?
You should indicate the relationship in the with method like this :
$houses = House::with('users')->get();
And one more thing it's better to get houses in the controller and pass them to the view :
$houses = House::with('users')->get();
return view('someView')->withHouses($houses);
And in the view do it like this :
#foreach ($houses as $house)
{{ $house->addres }}
#endforeach
To get only the houses taht has the users try this :
$houses = House::has('users')->get();
And to add some conditions on the users you can do it like this :
$houses = House::whereHas('users', function ($query) {
$query->where('name', 'some user name'); // to add some conditions on the user :)
})->get();
You should try this:
$houses = House::with('users')->get();
foreach ($houses as $house) {
echo 'Found House';
}
OR
In controller:
use House;
$houses = House::with('users')->get();
return view('someView',compact('houses'));
In Blade file:
#foreach ($houses as $house)
{{ $house->name }}
#endforeach
So I have defined relationship between OrderProduct.php and 'Product.php' models like this:
OrderProduct.php:
public function product()
{
return $this->belongsTo('App\Product');
}
Product.php
public function order()
{
return $this->belongsTo('App\OrderProduct');
}
OrderController function
public function orderShow($id)
{
//$order = Order::where('id', $id)->first();
$products = OrderProduct::where('id', 32)->first();
return view('admin.orders.show', compact('order', 'products'));
}
When I do this foreach:
#foreach($products as $product)
<?php dd($product) ?>
#endforeach
I get Invalid argument supplied for foreach() How to fix this ?
You've got only first record from set.
Try
public function orderShow($id)
{
//$order = Order::where('id', $id)->get();
$products = OrderProduct::where('id', 32)->get();
return view('admin.orders.show', compact('order', 'products'));
}
EDIT
If you need to retrieve particular record by id, use find() or even findOrFail() method (difference you can find in docs);
public function orderShow($id)
{
// this will retrieve record with id=32 from db if it exists,
// and throw Illuminate\Database\Eloquent\ModelNotFoundExceptio otherw
$product = OrderProduct::findOrFail(32);
return view( 'admin.orders.show', compact('product') );
}
then in your blade template you can access your $product info as an object, like so
{{ $product->name }}
{{ $product->otherProductProperty }}
You are giving
$products = OrderProduct::where('id', 32)->first();
which will fetch you only one record the result will not be a collection so you cannot do foreach for this
You can change it as
$products = OrderProduct::where('id', 32)->get();
to make it work
You need to even check the Relationship used. One will be belongs to and the other will be hasmany
you should try like this..
public function orderShow($id)
{
//$order = Order::where('id', $id)->get();
$products = OrderProduct::where('id', 32)->with('product')->get();
return view('admin.orders.show', compact('order', 'products'));
}
Okay so I just started learning Laravel and its fantastic. I just got stuck trying to retrive all the post from a user. Here is my code
models/User.php
public function posts()
{
$this->hasMany('Post');
}
models/Post.php
public function user()
{
$this->belongsTo('User');
}
controller/UserController.php
public function getUserProfile($username)
{
$user = User::where('username', '=', $username)->first();
$this->layout->content = View::make('user.index', array('user'=>$user));
}
views/user/index.blade.php
<div class="show-post">
<ul>
<li>{{ $user->posts }}</lo>
</ul>
</div>
I also tried:
#foreach($user->posts as $post)
<li>{{$post->post}}</li>
#endforeach
So im having trouble displaying the post for each specific user. Thank you.
So with the help of #WereWolf- The Alpha I was able to solve it and make my code better, If you notice I forgot to return my relationship functions. example:
Notice I hadn't returned it before
models/Post.php
public function users()
{
return $this->belongsTo('users');
}
But also the way I was querying my database was inefficient so Alpha showed me Eager Loading
http://laravel.com/docs/eloquent#eager-loading
example of controller
public function getUserProfile($username)
{
$user = User::with('posts')->where('username', '=', $username)->first();
$this->layout->content = View::make('user.index', array('user'=>$user));
}
and finally the view:
div class="show-post">
#foreach($user->posts as $post)
{{ $post->post }}
#endforeach
</div>
Actually $user->posts returns a collection of Post model so when you try this
{{ $user->posts }}
Laravel tries to echo that collection object which is not possible. You may try foreach loop instead:
#foreach($user->posts as $post)
{{ $post->somepropertyname }}
#endforeach
It's also possible to do something like this:
// Get first post->somepropertyname
{{ $user->posts->first()->somepropertyname }}
// Get last post->somepropertyname
{{ $user->posts->last()->somepropertyname }}
// Get first post->somepropertyname (same as first)
{{ $user->posts->get(0)->somepropertyname }}
// Get second post->somepropertyname from collection
{{ $user->posts->get(1)->somepropertyname }}
// Get the post->somepropertyname by id (post id) 2
{{ $user->posts->find(2)->somepropertyname }}
Also you may use eager loading like this (better):
$user = User::with('posts')->where('username', '=', $username)->first();
You may like this article about Cocllection.
Update: Also use return in model methods, like:
public function posts()
{
return $this->hasMany('Post');
}
I'm trying to get the username by a item with belongsTo.
I have this in my Item model:
public function user()
{
return $this->belongsTo('User', 'user_id', 'id');
}
And this in my controller:
$user = $item->user->username;
But I get:
Trying to get property of non-object
And when I do:
return $item->user->username;
In my controller it works.
What can be wrong?
Controller/Model: http://pastebin.com/qpAh8eFd
You have following function in your controller:
public function index($type)
{
$items = $this->item->where('type', '=', $type)->get();
foreach($items as $item):
$user = $item->user->username;
endforeach;
return View::make('items.index', ['items' => $items, 'user' => $user]);
}
You don't need to do a foreach look in the controller and whatever you are doing you are doing it wrong, instead make your index function like this:
public function index($type)
{
$items = $this->item->where('type', '=', $type)->get();
return View::make('items.index', ['items' => $items]);
}
Pass only $items to your items/index.blade.php view. You may do a foreach loop in your view if needed and within each iteration you may access the user related to the item using something like this:
#foreach($items as $item)
{{ $item->user->uername }}
#endforeach
You may get Trying to get property of non-object error message because each $item may don't have a related user. So, make sure each $item has a related user. You can also, use following to get items with user:
$items = $this->item->with('user')->where('type', '=', $type)->get();
return View::make('items.index', ['items' => $items]);
In your view you may check if the item has a related user:
#foreach($items as $item)
#if($item->user)
{{ $item->user->uername }}
#endif
#endforeach
