I have the following Eloquent query in a Laravel 5.2 project:
$regsByCtryCollection = Organisation::join('countries_currencies', 'countries_currencies.id', '=', 'organisations.country_id')
->select(DB::raw('DISTINCT LCASE(countries_currencies.country_code) AS ctry, COUNT(organisations.id) AS val'))
->groupBy('ctry')
->get();
The raw query produces this output:
ctry val
at 1
au 5
br 1
The Eloquent call produces a collection of three rows (matching raw query output) like this:
Collection {#791 ▼
#items: array:3 [▼
0 => Organisation {#777 ▼
#table: "organisations"
#hidden: []
........
#attributes: array:2 [▶]
#original: array:2 [▼
"ctry" => "at"
"val" => 1
]
#relations: array:5 [▶]
........
}
1 => Organisation {#778 ▶}
2 => Organisation {#779 ▶}
]
}
I then pluck the values and format for Highmaps like this
$regsByCtry = $regsByCtryCollection->pluck('ctry', 'val')->map(function($country, $value) {
return [
"hc-key" => $country,
"value" => $value
];
})->values()->toJson();
And one of the values is dropped and I get this:
[
{"hc-key":"br","value":1},
{"hc-key":"au","value":5}
]
Why is the first entry getting dropped?
{"hc-key":"at","value":1}
I am using this same process with two other Eloquent queries and it works as expected, but just not on this collection.
Additionally, I also sum all the values in the array of objects like this:
$regsTotal = array_sum($regsByCtryCollection->pluck('val')->toArray());
And I get the correct value, including all three records summed:
$regsTotal = 7;
The issue is with pluck('ctry', 'val'). This will return val as key & ctry as value. In your query output at & br has same value 1. So one of it getting replaced by the other one.
Try pluck('val', 'ctry')->map(function($value, $country)

so I’m running this query when a user selects multiple categories on the frontend of the site, I want it to bring back the products that are related to the selected categories… this works, however, I have 2 collections that I need to merge together. Here is the code:
$category = Category::whereIn('permalink', $request->get('categoryFilter'))->with('products')->get()->pluck('products');
I get the following back:
Illuminate\Support\Collection {#1779 ▼
#items: array:2 [▼
0 => Illuminate\Database\Eloquent\Collection {#1780 ▼
#items: []
#escapeWhenCastingToString: false
}
1 => Illuminate\Database\Eloquent\Collection {#1799 ▼
#items: array:24 [▶]
#escapeWhenCastingToString: false
}
]
#escapeWhenCastingToString: false
}
The first category has no products but the second has, is there a way of merging these 2 together?
Try this,
$category = Products::whereIn('category_id',Category::whereIn('permalink',
$request->get('categoryFilter')
)->pluck('id')
)->get();
I need to add pagination, but it seems complicated in my case, because I get data from database with paginate, but then I modify this data and when I call links() method on the blade, I get the following exception
Method Illuminate\Support\Collection::links does not exist.
My code in the Controller method:
$transactionsByLastMonth = Transaction::where('created_at', '>=', Carbon::now()->subDays(30)->toDateTimeString())
->where('user_id', Auth::user()->id)
->with(['user', 'propertyFrom', 'propertyTo', 'paddockFrom', 'paddockTo', 'cattleTypeFrom', 'cattleTypeTo'])
->paginate(10);
$transactionsByDays = collect(TransactionResource::collection($transactionsByLastMonth))
->sortByDesc('created_at')
->groupBy(function($date) {
return Carbon::parse($date['created_at'])->format('d');
});
return view('user.reports.index', compact('transactionsByDays'));
Yes, a pagination limits my data to 10 rows, but due to I'm grouping data by days, my collection modifies itself and I can't use $transactionsByDays->links() method to show pagination.
If see dd($transactionsByDays) , it looks like:
Illuminate\Support\Collection {#1381 ▼
#items: array:3 [▼
"01" => Illuminate\Support\Collection {#1019 ▼
#items: array:7 [▼
0 => array:16 [▶]
1 => array:16 [▶]
2 => array:16 [▶]
3 => array:16 [▶]
4 => array:16 [▶]
5 => array:16 [▶]
6 => array:16 [▶]
]
}
31 => Illuminate\Support\Collection {#1386 ▼
#items: array:2 [▼
0 => array:16 [▶]
1 => array:16 [▶]
]
}
30 => Illuminate\Support\Collection {#1384 ▼
#items: array:1 [▼
0 => array:16 [▶]
]
}
]
}
Therefore I need to paginate all arrays together which inside "01", 31, 30...
How can I do it?
Maybe rewrite code above in the controller somehow?
The main aim is that I need to group data to every day according to my json-resource class.
Any ideas?
I've found a solution gyus. I had to pass also a variable transactionsByLastMonth and use links() method over this.
In the meantime I use foreach on the my blade file over transactionsByDays variable. It's correctly works together cause it uses the same data from database, just in the first case its not filtered and not grouped and in the second one it is.
return view('user.reports.index', compact('transactionsByLastMonth', 'transactionsByDays'));
I have a deployments Laravel Collection like this:
Illuminate\Support\Collection {#415 ▼
#items: array:5 [▼
0 => array:7 [▼
"id" => 31
"status" => "active"
"name" => "Deployment 1"
"spots" => array:4 [▼
0 => array:2 [▼
"id" => 33
"status" => "active" <-- Want to change this
]
1 => array:2 [▶]
2 => array:2 [▶]
3 => array:2 [▶]
]
"data" => array:3 [▶]
]
1 => array:7 [▶]
2 => array:7 [▶]
3 => array:7 [▶]
4 => array:7 [▶]
]
}
I want to update the nested status value to inactive. I have used the Laravel map function, but it only seems to work on collections that have one nesting level. So this...
$this->deployments->map(function ($deployment) {
$deployment['spots'][0]['status'] = 'inactive';
});
dd($this->deployments);
...leaves $this->deployments untouched.
Also tried using nested map functions obtaining a Call to a member function map() on array exception on second level as second and next nesting levels are considered arrays...
Any thoughts?
Thanks in advance.
With the map method, you are almost there. You will have to return the change made in $deployment and do an ->all() at the end to update the collection with the modified values.
For updating a single spot:
$deployments = $deployments->map(function($deployment){
$deployment['spots'][0]['status'] = 'inactive';
return $deployment;
})->all();
For updating all spots:
$deployments = $deployments->map(function($deployment){
foreach($deployment['spots'] as &$spot){
$spot['status'] = 'inactive';
}
return $deployment;
})->all();
For anyone researching this, a more elegant solution might be:
For updating a single spot:
$data = $deployments->all();
$deployments = data_set($data, 'spots.0.status', 'inactive');
For updating all spots:
$data = $deployments->all();
$deployments = data_set($data, 'spots.*.status', 'inactive');
In my Laravel implemented web application i have Users and Roles tables with models which they are ManyToMany.
i want to get all users which they have specific role, for example:
$users = User::with(['roles' => function ($query) {
$query->whereLabel('is-portal-manager');
}])->get();
unfortunately this code return all users and compare role label and return that in relation ship array
Illuminate\Database\Eloquent\Collection {#2069 ▼
#items: array:3 [▼
0 => App\User {#2076 ▼
...
#relations: array:4 [▼
"properties" => null
"child" => Illuminate\Database\Eloquent\Collection {#2073 ▶}
"parent" => null
"roles" => Illuminate\Database\Eloquent\Collection {#2087 ▼
#items: array:1 [▼
0 => App\Entities\Role {#2074 ▼
...
#attributes: array:5 [▼
"id" => 1
...
"label" => "is-portal-manager"
...
]
...
}
]
}
]
...
}
1 => App\User {#2077 ▼
...
#relations: array:4 [▼
"roles" => Illuminate\Database\Eloquent\Collection {#2093 ▼
#items: []
}
]
...
}
]
}
as you can see in above output second user doesn't have any role and #items: [] is empty. i don't need to have this output structure and i want to have only which users have specific role, not all users with empty roles. second item of this collection shouldn't this output
Make your relationship conditional by using Laravel's whereHas:
$users = User::whereHas('roles', function ($query) {
$query->whereLabel('is-portal-manager');
})->with('roles')->get();

Is there a way to filter a collection returned by database query on Laravel?
Returned collection is this
1 => Person {#310 ▼
#table: "person"
#attributes: array:15 [▼
"name" => "Jon Doe"
"timeavailable" => "1,2,3,4,5,6,7,8"
2 => Person {#310 ▼
#table: "person"
#attributes: array:15 [▼
"name" => "Jon Moe"
"timeavailable" => "1,2,5,7,8"
Here, I want to filter the timeavailable attribute. I only want to show results for 1,2,3 . Is there a way to filter this collection so that I only get something like this
1 => Person {#310 ▼
#table: "person"
#attributes: array:15 [▼
"name" => "Jon Doe"
"timeavailable" => "1,2,3"
2 => Person {#310 ▼
#table: "person"
#attributes: array:15 [▼
"name" => "Jon Moe"
"timeavailable" => "1,2"
So, the filtered collection will have only 1,2,3 inclusions.
I think this is not the best solution, but it can be a way to solve for this problem. Check if this helps...
Try to use the map of Collection. In the inner function, you can explode, intersect and explode timeavailable.
$limiter = [1,2,3];
$filtered = $array->map(function($person, $k) use ($limiter) {
$ex = explode(',', $person->timeavailable);
$intersect = array_intersect($limiter, $ex);
$person->timeavailable = implode(",",$intersect);
return $person;
});
This will work fine for small results, but if you are planning to run this with lots of results, it will be slow.
