public function blog()
{
$posts = Post::all();
return view('blog')->with( [
'posts' => $posts,
]);
this is my function in the controller
you can do it as below
First method :
$posts = Post::orderBy('created_at', 'DESC')->get();
Second Method :
$posts = Post::latest();
Please view this: https://laravel.com/docs/7.x/eloquent. There are collections methods.
$urvar= Model::orderBy('column_name', 'DESC')->get();

I want to get category with all children subcategories and posts where id = category_id.
Posts should be paginated.
In category model I have 2 relations.
public function children() {
return $this->hasMany(self::class, 'parent_id');
}
public function posts() {
return $this->hasMany(Post::class, 'category_id');
}
In controller I have this function
public function getCategoryWithPaginatedPosts($slug, $perPage = null)
{
$columns = ['id', 'parent_id', 'title', 'slug', 'description', 'image'];
$postsColumns = ['category_id','title','text'];
$result = Category::whereSlug($slug)
->select($columns)
->with('children')
->with(['items' => function ($q) use ($postColumns) {
$q->wherePublished(true)
->select($postColumns)
->orderBy('id', 'ASC')
->paginate();
}])
->first();
}
Pagination doesn't work.
I just see that number of items is equal to $perPage parameter (and I have more items), but I don't see paginator inside dd($result->items)
It works like that, though I believe it is not the best way to do that.
So I can do it in few steps.
In first step I retrieve all data from DB and convert models to array, because I don't need models on webpage and I suppose it works faster like that. I would use ->toBase() if it could take mutators and relations from the model.
Second step I convert array into stdClass, because it is more comfortable in blade to work with object rather than with array.
Third step is to paginate items with mypaginate function (manual paginator in AppService Provider).
public function getCategoryWithPaginatedPosts($slug, $perPage = null)
{
$columns = ['id', 'parent_id', 'title', 'slug', 'description', 'image'];
$postsColumns = ['category_id','title','text'];
$result = Category::whereSlug($slug)
->select($columns)
->with('children')
->with(['items' => function ($q) use ($postColumns) {
$q->wherePublished(true)
->select($postColumns)
->orderBy('id', 'ASC');
}])
->first()
->toArray();
$result = Arr::arrayToObject($result);
$result->items = collect($result->items)->mypaginate($perPage);
return $result;
}
you should not use ->first() after ->paginate(), change something like this,
$result = Category::whereSlug($slug)
->select($columns)
->with('children')
->with(['items' => function ($q) use ($postColumns) {
$q->wherePublished(true)
->select($postColumns)
->orderBy('id', 'ASC')
}])
->paginate(20);
public function show($id)
{
$post = Post::find($id);
$comments = $post->comments()->orderBy('created_at', 'desc')->get()->transform(function ($item, $key) {
$item->registered = $item->created_at->diffForHumans();
return $item;
});
return view('blog_views.post')->with(['post' => $post, 'comments' => $comments]);
}
I want to add paginate(5) on $comments before return it to view and keep this values accessible in the view.
{{ $comment->user->name }} relationship returning the creator name of the comment
{{ $comment->registered }} get the created field in controller
And the new one -> paginate links
{{$comments->links()}}
I would use an accessor for your registered attribute and remove the need for iterating a collection manually to add it:
// Comment model
public function getRegisteredAttribute()
{
return $this->created_at->diffForHumans();
}
// Controller
public function show($id)
{
$post = Post::findOrFail($id);
$comments = $post->comments()
->with('user')
->latest()
->paginate(5);
return view('blog_views.post', [
'post' => $post,
'comments' => $comments,
]);
}
I have an ajax call that returns an array:
$reports = Report::where('submission_id', $submissionID)
->where('status', 'pending')
->get(['description','rule']);
return [
'message' => 'Success.',
'reports' => $reports,
];
From this array, I only want to return the fields 'description' and 'rule'. However I also want to return the owner() relationship from the Report model. How could I do this? Do I have to load the relationship and do some kind of array push, or is there a more elegant solution?
You can use with() to eager load related model
$reports = Report::with('owner')
->where('submission_id', $submissionID)
->where('status', 'pending')
->get(['id','description','rule']);
Note you need to include id in get() from report model to map (owner) related model
you will have probably one to many relationship with Reports and owners table like below
Report Model
public function owner() {
return $this->belongsTo('App\Owner');
}
Owner Model
public function reports() {
return $this->hasMany('App\Report');
}
your controller code
$reports = Report::with('owner')->
where('submission_id', $submissionID)->where('status', 'pending')->get()
return [
'message' => 'Success.',
'reports' => $reports,
];
This is what I ended up going with:
$reports = Report::
with(['owner' => function($q)
{
$q->select('username', 'id');
}])
->where('submission_id', $submissionID)
->where('status', 'pending')
->select('description', 'rule','created_by')
->get();
The other answers were right, I needed to load in the ID of the user. But I had to use a function for it to work.
How do you paginate the following line
$posts = Category::where('name', request('category'))->firstOrFail()->posts;
in the function below
public function index()
{
$categories = category::all();
if (request('category')) {
$posts = Category::where('name', request('category'))->firstOrFail()->posts;
} else {
$posts = post::where('status', 1)->orderBy('created_at', 'DESC')->paginate(5);
}
return view('user.blog', compact('posts', 'categories'));
}
You have to use the actual relationship method to get access to the query builder:
$posts = Category::where('name', request('category'))
->firstOrFail()
->posts()
->paginate(5);
See the Eloquent docs on Relationship Methods Vs. Dynamic Properties for reference.
I want to use map or transform in paginated collection in laravel 5.5 but I am struggling it work
This is what I was trying to do but getCollection is not available in LengthAwarePaginator as what we used to do in previous laravel versions see: How to transform paginated collection
$query = User::filter($request->all()
->with('applications');
$users = $query->paginate(config('app.defaults.pageSize'))
->transform(function ($user, $key) {
$user['picture'] = $user->avatar;
return $user;
});
This is what I receive but there is no pagination details in my result
How can I return transformed collection with pagination details?
For Laraval >= 8.x: if you want to perform the transform() on the collection of the paginated query builder result instead of doing the pagination on the full collection, one can use the method through():
User::filter($request->all()
->with('applications')
->paginate(config('app.defaults.pageSize'))
// through() will call transform() on the $items in the pagination object
->through(function ($user, $key) {
$user['picture'] = $user->avatar;
return $user;
});
I have ended up building custom paginate function in AppServiceProvider
use Illuminate\Support\Collection;
In register of AppServiceProvider
Collection::macro('paginate', function ($perPage, $total = null, $page = null, $pageName = 'page') {
$page = $page ?: \Illuminate\Pagination\LengthAwarePaginator::resolveCurrentPage($pageName);
return new \Illuminate\Pagination\LengthAwarePaginator(
$this->forPage($page, $perPage),
$total ?: $this->count(),
$perPage,
$page,
[
'path' => \Illuminate\Pagination\LengthAwarePaginator::resolveCurrentPath(),
'pageName' => $pageName,
]
);
});
You should paginate before retrieving the collection and transforming as follows:
$query = User::filter($request->all())->with('applications')->paginate(50);
$users = $query->getCollection()->transform(function ($user, $key) {
//your code here
});
dd($users);
It should give you your desired result.
Your problem is that you are printing the $users variable that hold the array of the users in the current page. To get the paginated list try to return/print $query instead.
So your code should be as following:
$query = User::filter($request->all()
->with('applications');
$users = $query->paginate(config('app.defaults.pageSize'))
->transform(function ($user, $key) {
$user['picture'] = $user->avatar;
return $user;
});
return response()->json($query);
Happy Coding!
You can use method setCollection from Paginator class:
https://laravel.com/api/8.x/Illuminate/Pagination/Paginator.html#method_setCollection
$messages = $chat->messages()->paginate(15);
$messages->setCollection($messages->getCollection()->transform(function($item){
$item->created = $item->created_at->formatLocalized('%d %B %Y %H:%M');
return $item;
}));
