I'm trying to get if user following or not the page. I'm trying like this:
public function get_following()
{
return $this->belongsTo(Followers::class, 'user_id')->where('type', '=', 1)->where('follower_id', '=', auth()->user()->id);
}
But this return null and I follow this page (got the item on table)...
dd($page)
Page {#305 ▼
#relations: array:3 [▼
"ptag" => Tag {#309 ▶}
"get_following" => null
"links" => Collection {#318 ▶}
]
DB:
followers.user_id = (pages.id), follower_id = (auth user), type = (1)

I'm using an API to get a list of countries in Laravel. I have been able to isolate the countries list only but the countries now have an inner array with details of the country. I only need the name. I've tried using foreach but it didn't work.
This below is the result from the api
#items: array:2 [▼
"countries" => array:198 [▼
0 => array:4 [▼
"code" => "BT"
"name" => "Bhutan"
"geonameid" => 1252634
"depends_on" => null
]
1 => array:4 [▶]
This below is the code fetching it
$response = Http::withHeaders([
'x-rapidapi-host' => 'world-geo-data.p.rapidapi.com',
'x-rapidapi-key' => '1fa601995fmshcc1d2fcc97ee24cp1ac29djsn9b9b11cc10ec',
//'x-rapidapi-key' => config('app.rapid_api_key'),
])->get('https://world-geo-data.p.rapidapi.com/countries');
//dd($response->collect());
return $response->collect()->pluck('name')
->all();
I'm trying to get only the name value. the return is returning null
I think this is what you want:
return collect($response->collect()["countries"])->pluck('name');
The result will be like:
I have datatable with a categories table.
I have two categories, Category A and Category B.
I also have a post table with post assigned to a category.
Now I can get all post and category
$posts = PostGroup::whereIn('name', ['A', 'B'])
PostGroup file has
public function posts() {
return $this->hasMany('App\Dict');
}
Ok now when I call code above and I get the following:
Collection {#301 ▼
#items: array:2 [▼
0 => PostGroup {#289 ▶}
1 => PostGroup {#302 ▶}
]
}
I can do foreach() or I can get posts
$posts = PostGroup::whereIn('name', ['A', 'B'])
$posts[0]->posts->where('group_id', 'A');
How can I avoid foreach and search the $posts collection to find group A something like:
$posts->where('group_id', 'A')->posts;
I do an ajax call and I have this code in the controller:
$menu = view('partials.nav_reserved_area', $data)->render();
return response()->json(['reserved_menu' => $menu]);
If I print $data variable before the render, this is what I get:
array:12 [▼
"request_url" => "https://www.example.com"
"theatre_events" => Collection {#515 ▼
#items: []
}
"music_events" => Collection {#498 ▼
#items: []
}
"others_events" => []
]
As You can see "theatre_events" and "music_events" are empty collection.
I do not why, but in the view, "theatre_events" and "music_events" have some items, as if it gets data from another ajax call or from another part of code.
How is it possible?
UPDATED
This should be the code incriminated (the other part of the code where maybe view gets data):
Model::whereHas('event', function ($query) {
$query
->where('end', '>=', \Carbon\Carbon::today())
->where('user_id', Auth::id())
->where('event_type', 'theatre');
})->paginate(20);
I'm trying to get the comments of the links with laravel relationship, the comments of links return normally, but I don't know how to get it in view or dd(), how can I do it?
Controller:
$page = Page::where('friendly_url', $id)
->select('id', 'photo', 'friendly_url', 'name', 'description', 'followers', 'links', 'tag_id', 'links_clicks')
->with('ptag', 'links', 'links.comments', 'links.tag')
->with(['links.comments.user' => function($query) {
$query->select('id', 'name', 'lastname');
}])->with(['links.comments.userProfile' => function($query) {
$query->select('id', 'photo');
}])->first();
dd($page->getRelation('links')
Collection {#301 ▼
#items: array:2 [▼
0 => Link {#307 ▼
#relations: array:2 [▼
"comments" => Collection {#316 ▼
#items: array:1 [▶]
"tag" => Tag {#322 ▶}
]
dd($page->getRelation('links')->getRelation('comments'))
BadMethodCallException
Method getRelation does not exist.
dd($page->getRelation('links')->comments)
Exception
Property [comments] does not exist on this collection instance.
EDIT:
I want to show the attributes of comment and comment.user, how I can do it?
foreach($page->getRelation('links')->pluck('comments') as $comment) {
dd($comment);
}
Collection {#327 ▼
#items: array:1 [▼
0 => Comment {#325 ▼
#attributes: array:5 [▼
"id" => 3
"content" => "teste"
"link_id" => 1
"user_id" => 1
"created_at" => "2018-01-11 00:47:32"
]
#relations: array:2 [▼
"user" => User {#330 ▼
#attributes: array:3 [▼
"id" => 1
"name" => "Halysson"
"lastname" => "Teves dos Santos"
]
}
"userProfile" => UserProfile {#326 ▶}
]
Try this-
foreach($page->links as $link){
$comments = $link->comments;
}
You should define relations first on relevent models and then using 'with' function can load models with relations OR a relation can be called directly by single model see documentation for further details
eg: you have defined a relation for user to phone, as user has a phone, one to one relation. in user model define a relation like
public function phone()
{
return $this->hasOne('App\Phone');
}
now to call this relation on user model instance.
$user = User::find(1);
dd($user->phone);
Because you're using the select() method, you also need to include all the foreign keys in it to allow Eloquent to be able to load these relationships.
But since you just start using Laravel, I'd recommend you to just remove select() method from this complex query.
If you want the links of a page :
$page->links
if you want all the comments of a page :
$page->links->pluck('comments')
that's it :)
I need to use switch cases to add constraints to the query I need to run. I need it to work with pagination, I tried this:
$albums = Album::with(array(
'images' => function ($query) {
$query->orderBy('order', 'asc');
}
))
->where('votes.votable_type','App\Models\Album')
->groupBy('albums.id');
$albums->published()->orderBy('created_at', 'desc')->paginate(30);
dd($albums);
and I get
Builder {#361 ▼
#query: Builder {#350 ▶}
#model: Album {#351 ▶}
#eagerLoad: array:2 [▶]
#macros: array:5 [▶]
#onDelete: Closure {#364 ▶}
#passthru: array:11 [▶]
#scopes: array:1 [▶]
#removedScopes: []
}
If I run
$albums = Album::with(array(
'images' => function ($query) {
$query->orderBy('order', 'asc');
}
))
->where('votes.votable_type','App\Models\Album')
->groupBy('albums.id')
->published()->orderBy('created_at', 'desc')->paginate(30);
dd($albums);
I get
LengthAwarePaginator {#467 ▼
#total: 97
#lastPage: 4
#items: Collection {#872 ▶}
#perPage: 30
#currentPage: 1
#path: "http://images.dev"
#query: []
#fragment: null
#pageName: "page"
}
why is there difference between these two approaches? I need to use first approach to be able to add constraints using switch case, I can't do that using second approach. But with first approach I do not get LengthAwarePaginator, how to fix it so that I get that?
You should redeclare the variable $albums if you wish it to be saved to this variable. Change this:
$albums->published()->orderBy('created_at', 'desc')->paginate(30);
To:
$albums = $albums->published()->orderBy('created_at', 'desc')->paginate(30);
