likvidatorTM left a reply on Pagination With Dinamic Data.

Because current page parameter user send with route argument and Paginator dont see it by default. But it doesn't matter since this is not the reason of problem. Route path: xhr/products/page/{page}/{filter?}

We can't use this principle because order column ISN'T unique!

Migration:

public function up()
{
    Schema::create('products', function (Blueprint $table) {
        $table->engine = 'InnoDB';
        $table->increments('id');
        $table->unsignedInteger('amount');
        $table->string('name', 30)->nullable();
        $table->enum('type', ['full-price', 'cut-price']);
        $table->timestamps();
    });
}

Controller:

public function index(Product $product, int $page = 1, string $filter = NULL)
{
    if ($filter && !in_array($filter, ['full-price', 'cut-price']))
        $filter = NULL;
    $page = (int)$page ?: 1;

    \Illuminate\Pagination\Paginator::currentPageResolver(function () use ($page) {
        return $page;
    });

    $paginator = $product->AvailableByPage($filter);
    $products['data'] = $paginator->items();
    $products['hasMore'] = $paginator->hasMorePages();
    if($page === 1)
        $products['total'] = $product->AvailableCount($filter);

    return $this->defaultResponse([
        'products' => [
            'items' => $products,
        ]]);
}

Model:

public function AvailableByPage(?string $filter)
{
    return Product::Select('*')
        ->if($filter, 'type', '=', $filter)
        ->where('amount', '>', 0)
        ->withSomethingElse()
        ->simplePaginate($this->items_per_page);
}

P/S its just example.

likvidatorTM started a new conversation Pagination With Dinamic Data.

Hi, i recently i used eloquent simple pagination but now i found some critical bug (eloquent method works fine, bug in my solution=)). In query i am use some conditions like if order active, if user can see this order end etc. When user gets next page results can be displaced and he gots incorrect data. For example: user loads first page with 10 orders after when he loads second page 8 of recent orders will set as "disabled" and response data will contains 2 orders that user already loaded. I cant use coursor pagination because order field not unique. I see only 1 way to resolve this problem: send from client orders ids that he loaded and then use its in query where `NOT IN. P/S its a SPA application.

likvidatorTM left a reply on Laravel And Vue.

I decided to use only Vue props and do all render on client-side.

likvidatorTM left a reply on Laravel And Vue.

Using Vue Props seems good but not perfect.

            <some-component inline-template
                            :user="{{ json_encode($user)}}">
                <div>
                    <span> {{ $user->name }} </span>
                    <span> {{ $user->last_name}} </span>
                </div>
            </some-component>

How tell Vue that user's name in first span and last name in second? Or how bind this with attributes?

likvidatorTM started a new conversation Laravel And Vue.

Hi! I'm don't understand how i can use laravel templates with Vue. Example:

<!--- index.html--->
<div id="app">
    <some-component inline-template>
        <div>
            <button type="button" @click="onButtonClick">
                {{$texts->text}}
            </button>
            <button type="button" @click="onButton2Click">
                {{$texts->text2}}
            </button>
        </div>
    </some-component>
</div>
<!--- some-component.vue--->
<script>
    export default {
        name: 'some-component',
        data() {
            return {
                buttonText: "",
        button2Text: "",
            }
        },
        methods: {
            onButtonClick() {
                this.buttonText = "Example";
            },
            onButton2Click() {
                this.buttonText2 = "Example2";
            }
        },
    }
</script>

And when user get this page he must see laravel-generated texts. Vue components will gets it into data vars. I don't know how do it beautifully. One of the ways I found:

<!--- index.html--->
<div id="app">
    <some-component inline-template>
        <div>
            <button type="button" @click="onButtonClick">
                <span v-html="buttonText">{{$texts->text}}</span>
            </button>
            <button type="button" @click="onButton2Click">
                <span v-html="buttonText2">{{$texts->text2}}</span>
            </button>
        </div>
    </some-component>
</div>

But in this case i must bind component data manually(differently texts will be overwritten).

P.S. Thanks in advance for your answers
