Unable to use whereHas in Laravel Algolia Scout - laravel

I am working on a Laravel project. I am using Scout based on Algolia. Now, I cannot apply whereHas to the search.
I have a model called Place which has many to many relationships with Category with the following code.
class Place extends Model
{
use Searchable, Localizable;
protected $with = [
'images',
'phones',
'emails',
'categories'
];
protected $casts = [
'is_featured' => 'boolean'
];
public function categories()
{
return $this->belongsToMany(Category::class, 'place_category');
}
public function searchableAs()
{
return "places_index";
}
public function toSearchableArray()
{
$record = $this->toArray();
$record['_geoloc'] = [
'lat' => $record['latitude'],
'lng' => $record['longitude'],
];
unset($record['created_at'], $record['updated_at'], $record['latitude'], $record['longitude']);
return $record;
}
}
As you can see it will be indexed on Algolia.
I am searching based on geolocation and keyword using the following code.
Place::search($keyword, function ($algolia, $query, $options) use ($latitude, $longitude) {
$location = [
'aroundLatLng' => $latitude . ',' . $longitude,
'aroundRadius' => config('scout.algolia.search_radius'),
];
$options = array_merge($options, $location);
return $algolia->search($query, $options);
});
The code is working fine until I also tried to filter by category. I changed my code to something like this.
$query = Place::search($keyword, function ($algolia, $query, $options) use ($latitude, $longitude) {
$location = [
'aroundLatLng' => $latitude . ',' . $longitude,
'aroundRadius' => config('scout.algolia.search_radius'),
];
$options = array_merge($options, $location);
return $algolia->search($query, $options);
});
if ($category) {
$query = $query->whereHas('categories', function ($query) use ($category) {
$query->where('categories.id', $category);
});
}
As you can see now, I am now filtering by categories too using whereHas. When I run the code, I got the following error.
BadMethodCallException
Method Laravel\Scout\Builder::whereHas does not exist.
Literally, I cannot use whereHas with Algolia search. How can I fix it? Also, I am thinking of indexing the categories and filter the records on the Algolia side.But I am going to be filtering by id. How can I customise the query for it?

Laravel / OctoberCMS frontend filter

I am using OctoberCMS and I have created a custom component. I am trying to create a frontend filter to filter Packages by the Tour they are assigned to.
This is what I have so far. The issue is that the code is looking for a tour field within the packages table rather than using the tour relationship. Does anyone have any ideas?
<?php namespace Jakefeeley\Sghsportingevents\Components;
use Cms\Classes\ComponentBase;
use JakeFeeley\SghSportingEvents\Models\Package;
use Illuminate\Support\Facades\Input;
class FilterPackages extends ComponentBase
{
public function componentDetails()
{
return [
'name' => 'Filter Packages',
'description' => 'Displays filters for packages'
];
}
public function onRun() {
$this->packages = $this->filterPackages();
}
protected function filterPackages() {
$tour = Input::get('tour');
$query = Package::all();
if($tour){
$query = Package::where('tour', '=', $tour)->get();
}
return $query;
}
public $packages;
}
I really appreciate any help you can provide.
Try to query the relationship when the filter input is provided.
This is one way to do it;
public $packages;
protected $tourCode;
public function init()
{
$this->tourCode = trim(post('tour', '')); // or input()
$this->packages = $this->loadPackages();
}
private function loadPackages()
{
$query = PackagesModel::query();
// Run your query only when the input 'tour' is present.
// This assumes the 'tours' db table has a column named 'code'
$query->when(!empty($this->tourCode), function ($q){
return $q->whereHas('tour', function ($qq) {
$qq->whereCode($this->tourCode);
});
});
return $query->get();
}
If you need to support pagination, sorting and any additional filters you can just add their properties like above. e.g;
protected $sortOrder;
public function defineProperties(): array
{
return [
'sortOrder' => [
'title' => 'Sort by',
'type' => 'dropdown',
'default' => 'id asc',
'options' => [...], // allowed sorting options
],
];
}
public function init()
{
$filters = (array) post();
$this->tourCode = isset($filters['tour']) ? trim($filters['tour']) : '';
$this->sortOrder = isset($filters['sortOrder']) ? $filters['sortOrder'] : $this->property('sortOrder');
$this->packages = $this->loadPackages();
}
If you have a more complex situation like ajax filter forms or dynamic partials then you can organize it in a way to load the records on demand vs on every request.e.g;
public function onRun()
{
$this->packages = $this->loadPackages();
}
public function onFilter()
{
if (request()->ajax()) {
try {
return [
"#target-container" => $this->renderPartial("#packages",
[
'packages' => $this->loadPackages()
]
),
];
} catch (Exception $ex) {
throw $ex;
}
}
return false;
}
// call component-name::onFilter from your partials..
You are looking for the whereHas method. You can find about here in the docs. I am not sure what your input is getting. This will also return a collection and not singular record. Use ->first() instead of ->get() if you are only expecting one result.
$package = Package::whereHas('tour', function ($query) {
$query->where('id', $tour);
})->get();

Laravel - request validation

I extedned request class to create my own valdiation rules. In that class I added my custom validation function. In function I check if tags are pass regEx and I would like to filter tags to remove tags shorter then 2 characters.
And later keep in request only tags that passed validation.
public function createPost(PostRequest $request)
{
dd($request->all()); //In this place I would like to keep only tags passed through validation not all tags recived in request
}
Is it possibile to do it? How to set it in Request class?
'tags' => [
'nullable',
'string',
function ($attribute, $value, $fail){
$tagsArray = explode(',', $value);
if(count($tagsArray) > 5) {
$fail(__('place.tags_max_limit'));
}
$tagsFiltered = [];
foreach ($tagsArray as $tag){
$tag = trim($tag);
if(preg_match('/^[a-zA-Z]+$/',$tag)){
$tagsFiltered[] = $tag;
};
}
return $tagsFiltered;
}
],
EDIT:
I think we miss understanding. I would like to after validation have only tags that returned in variable $tagsFiltered; Not the same as recived in input.
You have to create this custom regex rule and use it into rules() function.
Like so:
public function rules()
{
return [
'tag' => 'regex:/[^]{2,}/'
];
}
public function createPost(PostRequest $request)
{
$request->validated();
}
And then just call it via validated() function wherever you want.
first define validation rule with this command:
php artisan make:rule TagsFilter
navigate to TagsFilter rule file and define your filter on passes method:
public function passes($attribute, $value)
{
$tagsArray = explode(',', $value);
$tagsFiltered = [];
foreach ($tagsArray as $tag){
$tag = trim($tag);
if(preg_match('/^[a-zA-Z]+$/',$tag)){
$tagsFiltered[] = $tag;
};
}
return count($tagsArray) > 5 && count($tagsFiltered) > 0;
}
then include your rule in your validation on controller:
$request->validate([
'tags' => ['required', new TagsFilter],
]);

how to filter with two or more combinations in laravel

enter code hereMy question about the combination filters in laravel by using eloquent.
I am trying to filter with a combination of the following:
username
Category
Sub_category
started_at
created_at
status
I use where conditions but it not working as required.
public function filter(Request $request, User $user)
{
$user = $user->newQuery();
// Search for a user based on their name.
if ($request->has('username')) {
$user->where('name', $request->input('username'));
}
// Search for a user based on their Category.
if ($request->has('Category')) {
$user->where('Category', $request->input('Category'));
}
// Search for a user based on their Sub_category.
if ($request->has('Sub_category')) {
$user->where('Sub_category', $request->input('Sub_category'));
}
// Search for a user based on their started_at.
if ($request->has('started_at')) {
$user->where('started_at', $request->input('started_at'));
}
// Search for a user based on their status.
if ($request->has('status')) {
$user->where('status', $request->input('status'));
}
// Continue for all of the filters.
// Get the results and return them.
return $user->get();
}
You should save your where conditions to the $user variable.
$user = $user->where($dbField, $request->input($requestParam));
For improved readability, I'd suggest using a loop with all of your filtering cases.
public function filter(Request $request)
{
$users = User::query();
$filters = [
'username' => 'name',
'Category' => 'Category',
'Sub_category' => 'Sub_category',
'started_at' => 'started_at',
'status' => 'status'
];
foreach ($filters as $requestParam => $dbField){
if ($request->has($requestParam)) {
$users = $users->where($dbField, $request->input($requestParam));
}
}
return $users->get();
}
Bear in mind $request->has does not check whether the parameter value is empty, use $request->filled if you wish so.
This is My examle refer this
public function filter(Request $request)
{
$q = User::query();
$email = $request->input('email');
$username= $request->input('username');
$q->when($email,function ($query) use ($email){
$query->where('email',$email);
});
$q->when($username,function ($query) use ($username){
$query->where('username',$username);
});
$results = $q->get();
//code
}

Search Method with pagination result

I made a search method (GET) with some filters, the only problem that i have is when i run the search result i get the results with pagination with the adresse like :
search?q=&type_licence_id=&activite_licence_id=&structure_id=8
when i click on page 2 for exemple i have :
search?page=2
So it's display me anymore the results from the search query.
Maybe i done something wrong on my controller ? Hope someone could help me , thanks a lot in advance
here my controller :
public function search(Request $request)
{
$structure = Structure::select('num_structure', 'nom_structure' , 'id')
->get()
->mapWithKeys(function($i) {
return [$i->id => $i->num_structure.' - '.$i->nom_structure];
});
$activite = ActiviteLicencie::pluck('lb_activite' , 'id');
$type_licence = Type_licence::pluck('lb_type' , 'id');
$query = Licencies::query();
$filters = [
'type_licence_id' => 'type_licence_id',
'activite_licence_id' => 'activite_licencie_id',
'structure_id' => 'structure_id',
];
foreach ($filters as $key => $column) {
$query->when($request->{$key}, function ($query, $value) use ($column) {
$query->where($column, $value);
});
}
$licencies = $query->paginate(10);
return view('licencie/recherche', compact('licencies' , 'structure' , 'activite' , 'type_licence'));
}
I use the following in my blade template:
{{ $licencies->appends(Request::all())->links() }}
It appends all your request parameters to the pagination.
Check 'Appending To Pagination Links' on https://laravel.com/docs/5.4/pagination#displaying-pagination-results for information
You could customize the Pagination URL by
$licencies = $query->paginate(10);
$licencies->setPath($request->fullUrlWithQuery());

Laravel Excel - Select columns to export

I'm using Laravel Excel from maatwebsite but i have a problem with export data to xls file. I have this query but i don't need to show all columns in the xls file but i need to select all this columns to do operations before download the file. In my select i have 8 columns but in my headers i just have 7 to show but this doesn't work because the 8ª column appears too.
MY FUNCTION:
public function toExcel($id) { $b = Budget::find($id);
$budget = Budget_Item::join('budgets', 'budget__items.id_budget', '=', 'budgets.id')
->join('items_sizes', 'budget__items.id_itemSize', '=', 'items_sizes.id')
->join('items', 'items_sizes.id_item', '=', 'items.id')
->join('material_types', 'items_sizes.id_materialType', '=', 'material_types.id')
->select('items.reference AS Referência', 'items.name AS Descrição', 'items_sizes.size AS Tamanho', 'material_types.material_type AS Material', 'budget__items.amount AS Quantidade', 'items_sizes.unit_price AS Val.Unitário', 'budget__items.price AS Val.Total', 'budget__items.purchasePrice')
->where('id_budget', '=', $id)
->get();
$budgetUpdate = [];
$budgetUpdate[] = ['Referência', 'Descrição', 'Tamanho', 'Material', 'Quantidade', 'Val.Unitário', 'Val.Total'];
foreach ($budget as $key)
{
if ($key->purchasePrice > 0)
{
$key->unit_price = $key->purchasePrice;
}
$budgetUpdated[] = $key->toArray();
}
Excel::create('Proposta_'.$b->reference, function($excel) use($budgetUpdated)
{
// Set the title
$excel->setTitle('Proposta');
$excel->sheet('Sheetname', function($sheet) use($budgetUpdated)
{
$sheet->fromArray($budgetUpdated, null, 'A1', false, true);
});
})->download('xls');}
How can i solve that?
Thank's
Tested on Laravel excel 3.1 docs
on controller
public function exportAsCsv()
{
return Excel::download(new MyExport, 'invoices.xlsx');
}
on MyExport, look at the map function
class MyExport implements FromCollection, WithHeadings, WithMapping{
public function collection(){
return MyTable:all();
}
// here you select the row that you want in the file
public function map($row): array{
$fields = [
$row->myfield2,
$row->myfield1,
];
return fields;
}
}
also check this
For what its worth I ran into a similar issue and didnt find much in terms of a fix so heres my solution.
1. I query the DB in the callback and get all the data I need.
2. I then go over the collection and create a new array on each iteration and assign a value & header. Works great for picking out columns from a model
Excel::create('User List Export', function($excel) {
$excel->sheet('Users', function($sheet) {
$email = yourModelGoesHere::all();
foreach ($email as $key => $value) {
$payload[] = array('email' => $value['email'], 'name' => $value['name']);
}
$sheet->fromArray($payload);
});
})->download('xls');
You can try this way.
$user_id = Auth::user()->id
Excel::create('User', function($excel) use ($user_id){
$excel->sheet('Sheet', function($sheet) use($user_id){
$user = User::where('user_id', $user_id)->select('name', 'email', 'role', 'address')->get();
});
})->export('xls');
return redirect('your route');
