I would like to fetch sum of quantity in each month, so that I can display on bar chart quantities against month This is what I thought but didn't workout $data1 = Borrow::groupBy(function($d) { return Carbon::parse($d->created_at)->format('m')->sum('quantity'); })->get(); My table structure Schema::create('borrows', function (Blueprint $table) { $table->increments('id'); $table->integer('member_id'); $table->integer('book_id'); $table->integer('quantity'); $table->integer('status')->default(0); $table->timestamps(); }); that a collection group by not an eloquent groupby if you want to do it

I have a laravel collection object. I want to use the nth model within it. How do I access it? Edit: I cannot find a suitable method in the laravel documentation . I could iterate the collection in a foreach loop and break when the nth item is found: foreach($collection as $key => $object) { if($key == $nth) {break;} } // $object is now the nth one But this seems messy. A cleaner way would be to perform the above loop once and create a simple array containing all the objects in the collection. But this seems like unnecessary duplication. In the laravel collection class documentation , there is

I have a questions table and a tags table. I want to fetch all questions from tags of a given question. So, for example, I may have the tags "Travel," "Trains" and "Culture" attached to a given question. I want to be able to fetch all questions for those three tags. The tricky, so it seems, is that questions and tags relationship is a many-to-many defined in Eloquent as belongsToMany. I thought about trying to merge the questions Collections as below: foreach ($question->tags as $tag) { if (!isset($related)) { $related = $tag->questions; } else { $related->merge($tag->questions); } } It doesn

If I run $collection->filter(myFilter) , Laravel does this annoying thing of adding keys to each model in the collection like so: { "4": { "myObject": "data" }, "7": { "myObject": "data" } } How can I get rid of the "4" and "7" so it's an array of my objects? My code that runs is: $obj = Cars::with('brand')->orderBy('id')->get(); return $obj->filter(function($value, $key) { return $value->display == true; }); The issue is that the filter() method does not rekey the underlying collection array. So, the Collection is still representing an array, it is just that your array looks like this: [ 4 =>

I have a Seller object which has a related User. I need to fill a select from LaravelCollective so I need to make something like this: {!! Form::selectGroup('seller_id', 'Seller', Seller::with('user')->pluck('user.first_name', 'id')->toArray(), null) !!} The problem is that I cannot take fields from relationships (user.first_name). How can I do it? UPDATE I want to avoid doing this... <?php $sellers = []; Seller::with('user')->get()->each(function ($seller) use (&$sellers) { $sellers[$seller->id] = $seller->user->first_name; }); ?> You can use Laravel's pluck method as: $sellers = Seller::with

This may be a trivial question but I am wondering if Laravel recommends a certain way to check whether an Eloquent collection returned from $result = Model::where(...)->get() is empty, as well as counting the number of elements. We are currently using !$result to detect empty result, is that sufficient? As for count($result) , does it actually cover all cases, including empty result? Gary Green When using ->get() you cannot simply use any of the below: if (empty($result)) { } if (!$result) { } if ($result) { } Because if you dd($result); you'll notice an instance of Illuminate\Support
