Laravel Collection paginate does not exist
(2 answers)
Closed last year.
This is my controller file's index function
public function index()
{
$projects = Projects::All()->paginate( 5 );
return view('projects.index')->with('projects', $projects);
}
And, This is my blade file's pagination code
#foreach ($projects as $project)
{{ $project->links('pagination::tailwind') }}
#endforeach
But, Still, there's an error, that is saying
BadMethodCallException
Method Illuminate\Database\Eloquent\Collection::paginate does not exist.
You have a typo. This is not correct:
{{ $project->links('pagination::tailwind') }}
Error 1: You are missing a 's':
{{ $projects->links() }}
Error 2: You do not have to put your links in the loop but outside the loop. normaly after the loop.
#foreach($records as $record)
{{ $record->field }}
#endforeach
{{ $records->links() }}
Suggestion: I prefer to tell laravel which paginator I am using in this file:
App/Providers/AppServiceProvider.php
public function boot()
{
Paginator::useBootstrap(); //bootstrap in this case
}
For tailwind, there is no need to specify anything, since it is the default.

I'm using Laravel 5.6 and I have created two Models Question and User Model and these are linked to each other using one to many relation as:
Question Model
public function user() {
return $this->belongsTo('App\User');
}
User Model
public function questions() {
return $this->hasMany('App\Question');
}
And my controller code is:
public function index()
{
$user = User::all();
return view('home', compact('user'));
}
So, i'm trying to get question title and I have written this code in blade:
#foreach($user as $user)
{{ dd($user->questions->questions_title) }}
#endforeach
But getting error undefined index questions_title, but if only write this {{ dd($user->questions) }} it gave me all questions, so how to fix it.
I have also tried {{ dd($user->questions['questions_title']) }} but not fixed.
You'll want to loop over your questions relationship to see your question:
#foreach($user as $u)
#foreach($u->questions as $question)
{{ dd($question->questions_title) }}
#endforeach
#endforeach
Note: I changed $user to $u
In your controller, you are not eager loading your questions relationships. Change your code to the following:
public function index()
{
$user = User::with('questions')->get();
return view('home', compact('user'));
}
Using the with() method will load all specified relationship with the eloquent query. After this, you will need to loop through the questions collection using the ->each() collection method.
#foreach($users as $user)
#foreach($user->question as $question)
{{ $question->question_title }}
#endforeach
#endforeach
No need for two foreach loops we can simply use one like below:
#foreach ($user->questions as $question)
{{ dd($question->questions_title) }}
#endforeach
Was wondering if someone could check this out and let me know what I'm doing wrong. I'm trying to use paginate on a database query and render it in my view.
Is my DB query incorrect? I was following the docs to create it. Also read that I needed to remove ->get() when using paginate.
This is what is giving the error on my view: {{$item->paginate(4)}}, same happens if I use {{$item->links(4)}}
Everything renders fine if I remove paginate from the query in the controller..?
Here is what I'm working with.
Controller:
public function index()
{
// $news = DB::table('news')->orderBy('id', 'DESC')->paginate(4);
$news = DB::table('news')->select('id','title','description','listing_image','created_at','updated_at')->orderBy('id', 'DESC')->paginate(4);
return view('news.index',compact('news'));
}
View: (Getting error: Call to undefined method stdClass::paginate())
#if ($news->count())
#foreach($news as $item)
...html
#if ($item->listing_image)
...more html
#else
#endif
... more html
#endforeach
{{$item->paginate(4)}}
#endif
change {{$item->paginate(4)}} to {{ $news->links() }}
I have Post model which has user function returning User model - creator of the post.
class Post extends Model
{
/**
* Get the user that owns the post.
*/
public function user()
{
return $this->belongsTo(User::class);
}
}
In blade view I achieved how to print author name
{{ $post->user->name or 'Anonymous' }}
Above code works, but it is very hmm sensitive?
For example, I tried change this code to:
{{ $post->user->name, 'Anonymous' }}
<?php $post->user->name or 'Anonymous' ?>
Results? Trying to get property of non-object error on line with this code.
Maybe I am skipping something simple but important. How to print URL or default value in blade view. Pseudo code what I mean:
{{ '' or 'Anonymous' }}
Try
{{ isset($post->user->name) ? '' : 'Anonymous' }}
If this doesn't work (I haven't check it) try something like this:
#if (isset($post->user->name))
#else
Anonymous
#endif
Actually the error is not because the code is sensitive, it is because you are actually trying to access non objects values.
To achieve what you are looking for:
{{ isset($post->user)?'' : 'Anonymous' }}
I need to find out unique value. So I tried bellow code. It is through undefined variable error.
Controller:
$employee = Employee::all();
Return view ('page', compact('employee'));
Page view:
$uniqueEmpLoc = $employee->unique('location')->values()->list('location')->toArray();
#Foreach($uniqueEmpLoc as $empLoc)
{{ $empLoc }}
//this is select box used for search
#endforeach
//Display Entire data
#foreach($employee as #employee)
//Display all value
#endforeach
But I got an uniqueEmpLoc is undefined error. I'm using LARAVEL 5.1. Please help me to solve this problem.
There are some errors in your code:
I don't think compact(employee) would work. Shouldn't that suppose to be compact('employee') ?
In Blade, there is no need of putting curly braces at all. Remove them.
Try out the following:
$employees = Employee::unique('locations')->values()->list('location')->toArray();
return view('page', compact('employees'));
And then in your view:
#foreach($employees as $employee)
{{ $employee }}
#endforeach
Use this query in controller
$employees = Employee::distinct()->list('location')->toArray();
return view('page', compact('employees'));
In view
#foreach($employees as $employee)
{{ $employee }}
#endforeach
I agree with the other answers here, this code should be in the controller. You shouldn't be doing logic in the views.
In the controller do:
$uniqueEmpLoc = $employee->unique('location')->values()->list('location')->toArray();
$employee = Employee::all();
Return view ('page', compact('employee', 'uniqueEmpLoc'));
The reason your code isn't working is the line that defines $uniqueEmpLoc is interpreted by blade as text, not code.
If you really want to do that in the view, you need to wrap it in #php tags.
#php
$uniqueEmpLoc = $employee->unique('location')->values()->list('location')->toArray();
#endphp
#Foreach($uniqueEmpLoc as $empLoc)
{{ $empLoc }}
//this is select box used for search
#endforeach

How to pass data to view in Laravel?
(15 answers)
Closed 2 years ago.
I have made a list query that populates my drop down box. I have tried var_dump on the controllers part and it all went well, but whenever I tried to call my function on my blade template, it would return me an error: Undefined variable: categories (View: C:\wamp\www\airlines\app\views\content\onewayflight.blade.php)
What seems to be the problem here?
OnewayflightController.php
public function onewayflight()
{
$categories = DB::table('oneways')->lists('destination-from');
return View::make('content.onewayflight')->with('destination-from', $categories);
}
onewayflight.blade.php
{{ Form::select('destination-from', $categories) }}
routes.php
Route::get('flight/onewayflight','OnewayflightController#onewayflight');
You should use in Blade:
{{ Form::select('destination-from', $destination-from) }}
because in your method you used:
with('destination-from', $categories)
so you told that in Blade $categories have to be named $destination-from
However you cannot use - in variable name, so you should probably change it into:
with('destinationFrom', $categories)
and in Blade:
{{ Form::select('destination-from', $destinationFrom) }}
