Good Evening.... Hope i can explain my problem correctly.
I am getting data (ID) in array and value (numbers) in controller. Now i want to save the "numbers" in each "ID".
array ID ["Buffalo-01", "Buffalo-02", "Buffalo-04"]
Numbers - 40.
Want to save 40 to each ID.
Controller
public function addbuffalototalmilk(Request $req )
{
$buffalomilking = Buffalodata::where('avgmilk','<>','0')->Where('status','=','Available')->count(); // MIlking Animal Nos
$getbuffalomilkingid = Buffalodata::where('avgmilk','<>','0')->Where('status','=','Available')->pluck('buffaloID'); // Get Buffalo Details of Milking
$totalmorningmilk = $req->get('morningtotalmilk');
$totaleveningmilk = $req->get('eveningtotalmilk');
$eachmorningmilk = ($totalmorningmilk / $buffalomilking);
$eacheveningmilk = ($totaleveningmilk / $buffalomilking);
return response ();
}
Thanks in Advance
Is this what you are looking for ?
$buffalomilking = Buffalodata::where('avgmilk', '<>', '0')
->Where('status', '=', 'Available')
->count();
$getbuffalomilkingid = Buffalodata::where('avgmilk', '<>', '0')
->Where('status', '=', 'Available')
->pluck('buffaloID');
foreach ($getbuffalomilkingid as $id) {
Buffalodata::where('id', $id)->update([
'number' => $buffalomilking,
]);
}

So I am trying to get a list of all active clients that have active jobs but I'm at a loss of how to accomplish this. So here is what I have...
$query = Client::select( 'clients.*' )->where( 'is_enabled', 1 )->activeJobs();
Which throws an error
Call to undefined method Illuminate\Database\Eloquent\Builder::activeJobs()
in my client model i have the activeJobs() function as follows:
public function activeJobs()
{
return $this->hasMany( Job::class )->where( 'is_active', 1 );
}
Just to explain what I am after with my query in words, I'm trying to get a collection of all active client items (determined by is_enabled = 1) which have 1 or more active jobs (determined by is_active = 1)
thanks
What you are looking for is has/whereHas.
So, what you should do is
$query = Client::select('clients.*')
->whereHas('jobs', fn($query) => $query->where('is_active', 1))
->where('is_enabled', 1)
->get();
This will return you a collection of Clients whose Job's is_active column is 1
Try this
$query = Client::select('clients.*')
->where('is_enabled', 1)
->whereHas('activeJobs', function ($query) {
$query->where('is_active', 1);
})
->get();
Try this
$query = Client::has('activeJobs', '>', 1)->get();
Try This:
$query = Client::with('activeJobs')->select( 'clients.*' )->where( 'is_enabled', 1 );
This will return the clients with their relationship(Active Jobs), what you are doing in the code is trying to grab relationship data from collection..
You can either grab the clients, then foreach $client->activeJobs;
or use with which wil return it in query level.
Get active jobs and then collect related users:
$cliensWithActiveJobs = Job::with('client')
->where('is_active', 1)
->get(['id', 'client_id'])
->map(fn ($job) => $job->client)
->unique('id');
Can somebody tell me what am I doing wrong?
I want to get all projects with status 0 and if any of data matches in eloquent.
My code is like this
public function search(Request $request){
if($request->has('q')){
$search_query = $request->input('q');
$projects = Project::where(['status' => '0'])->get();
$projects = $projects->where(function($query) use ($search_query) {
$query->where('title','LIKE','%'.$search_query.'%')
->orWhere('shortDescription','LIKE','%'.$search_query.'%')
->orWhere('longDescription','LIKE','%'.$search_query.'%')
->orWhere('tags','LIKE','%'.$search_query.'%')
->orWhere('projectLink','LIKE','%'.$search_query.'%');
});
$projects->get();
dd($projects);
}
}
And I am getting this error
ErrorException
explode() expects parameter 2 to be string, object given
I solved the problem but changed the code a little bit... If you like, take it! I tested and it's working.
if($request->has('q')){
// Your $request->q Value
$term = $request->q;
$projects = DB::table('tbl_projects')->where('status', '=', 0)
->where(function ($query) use ($term) {
$query->where('title', 'LIKE', '%'.$term.'%')
->orWhere('shortDescription', 'LIKE', '%'.$term.'%')
->orWhere('longDescription', 'LIKE', '%'.$term.'%')
->orWhere('tags', 'LIKE', '%'.$term.'%')
->orWhere('projectLink', 'LIKE', '%'.$term.'%');
})
->get();
//dd($projects);
}
Raw query is:
select * from `tbl_projects` where `status` = 0 and (`title` LIKE %bla bla% or `shortDescription` LIKE %bla bla% or `longDescription` LIKE %bla bla% or `tags` LIKE %bla bla% or `projectLink` LIKE %bla bla%))
Regards!
Your error is
$projects = Project::where(['status' => '0'])->get();
(['status' => '0']) Where clause params required is different. You must use ('status', '0') or ('status', '=', '0')
When you use ->get(), you have a Collection or EloquentCollection object. You need a QueryBuilder
Try to implement a better programation logic.
A better implementation is
public function search(Request $request){
if($request->has('q')){
// Add array with field coincidences target. Is better if this array is a const static field in the Project model
$searchFields = ['title', 'shortDescription', 'longDescription', 'tags', 'projectLink' ];
// Now you can add 100 fields for search coincidences easily
$search_query = $request->input('q');
$projects = Project::where('status', '0');
foreach($searchFields as $searchField){
if ($searchField == 'title'){
$projects = $projects->where($searchField,'LIKE',"%$search_query%");
continue;
}
$projects = $projects->orWhere($searchField,'LIKE',"%$search_query%");
}
$projects = $projects->get();
dd($projects);
}
}
I'm making a "simple" api for laravel. This api has to handle with filters, pagination and sorting the result. To make this I use laravel query builder. The problem is that it's making a select without a table name, for example:
select * order by `id` asc
My code:
public function index()
{
$request = request();
$query = DB::table('customers')->newQuery();
// Orden
if (request()->has('sort')) {
// Multiorden
$sorts = explode(',', request()->sort);
foreach ($sorts as $sort) {
list($sortCol, $sortDir) = explode('|', $sort);
$query = $query->orderBy($sortCol, $sortDir);
}
} else {
$query = $query->orderBy('id', 'asc');
}
//Filtros
if ($request->exists('filter')) {
$query->where(function($q) use($request) {
$value = "%{$request->filter}%";
$q->where('name', 'like', $value)
->orWhere('address', 'like', $value);
});
}
$perPage = request()->has('per_page') ? (int) request()->per_page : null;
$pagination = $query->get()->paginate($perPage);
$pagination->appends([
'sort' => request()->sort,
'filter' => request()->filter,
'per_page' => request()->per_page
]);
return response()->json(
$pagination
);
}
Error:
Illuminate\Database\QueryException: SQLSTATE[HY000]: General error:
1096 No tables used (SQL: select * order by id asc) in file
C:\xampp\htdocs\iService\vendor\laravel\framework\src\Illuminate\Database\Connection.php
on line 664
UPDATE:
return DB::table('customers')->get();
If i use this, the api works fine, I have more apis working. The problem is that I need Query Builder to handle filters, sort, etc...
The problem was the way I instance a new query.
$query = DB::table('customers')->newQuery();
Correct:
$query = Model::query();
For my example:
$query = Customer::query();
Let's say I have two models: Park and Items. Each Park can have a number of Items, through a HasMany relationship.
In Items table there's a park_id field and a type flag: an Item can be a fountain, or a basketball court, or whatever.
What I need to do is to filter the parks to obtain only those who has ALL of the item types passed in an array. This is what I have:
$parks = Park::whereHas('items', function($q) use ($request) {
$q->where('type', json_decode($request->type_list));
})->get();
But it's not working properly. Any ideas?
Thanks a lot, and happy new year to all!
Edit: I've found a working though really ugly solution:
$types_array = json_decode($request->type_list, true);
$results = [];
// A collection of parks for each item type
foreach($types_array as $type) {
$results[] = Park::whereHas('items', function($q) use ($type) {
$q->where('type', $type);
})->get();
}
// Intersect all collections
$parks = $results[0];
array_shift($results);
foreach ($results as $collection) {
$parks = $collection->intersect($parks);
}
return $parks;
You can use a foreach in whereHas method. It should be something like this:
$array = json_decode($request->type_list, true)
$parks = Park::whereHas('items', function($q) use ($array) {
foreach ($array as $key => $type) {
$q->where('type', $type);
}
})->get();
I think using where clause to match all item's type for the same row will result nothing, it's like doing where id = 1 and id = 2 and this is impossible because id can take only one value, what you should do is to use whereIn to get all items that match at least one type and then use groupBy to group result by park_id, then in the having clause you can check if the group count equal the type_list count:
$types = json_decode($request->type_list, true);
$parks = Park::whereHas('items', function($q) use ($types) {
$q->select('park_id', DB::raw('COUNT(park_id)'))
->whereIn('type', $types)
->groupBy('park_id')
->havingRaw('COUNT(park_id) = ?', [ count($types) ]);
})->get();
You can add multiple whereHas() constraint to one query:
$types_array = json_decode($request->type_list, true);
$query = Park::query();
foreach($types_array as $type) {
$query->whereHas('items', function($q) use($type) {
$q->where('type', $type);
});
}
$parks = $query->get();
I'd like to know the position of a user based on its creation date. How do I do that using Eloquent?
I'd like to be able to do something like this:
User::getRowNumber($user_obj);
I suppose you want MySQL solution, so you can do this:
DB::statement(DB::raw('set #row:=0'));
User::selectRaw('*, #row:=#row+1 as row')->get();
// returns all users with ordinal 'row'
So you could implement something like this:
public function scopeWithRowNumber($query, $column = 'created_at', $order = 'asc')
{
DB::statement(DB::raw('set #row=0'));
$sub = static::selectRaw('*, #row:=#row+1 as row')
->orderBy($column, $order)->toSql();
$query->remember(1)->from(DB::raw("({$sub}) as sub"));
}
public function getRowNumber($column = 'created_at', $order = 'asc')
{
$order = ($order == 'asc') ? 'asc' : 'desc';
$key = "userRow.{$this->id}.{$column}.{$order}";
if (Cache::get($key)) return Cache::get($key);
$row = $this->withRowNumber($column, $order)
->where($column, '<=',$this->$column)
->whereId($this->id)->pluck('row');
Cache::put($key, $row);
return $row;
}
This needs to select all the rows from the table till the one you are looking for is found, then selects only that particular row number.
It will let you do this:
$user = User::find(15);
$user->getRowNumber(); // as default ordered by created_at ascending
$user->getRowNumber('username'); // check order for another column
$user->getRowNumber('updated_at', 'desc'); // different combination of column and order
// and utilizing the scope:
User::withRowNumber()->take(20)->get(); // returns collection with additional property 'row' for each user
As this scope requires raw statement setting #row to 0 everytime, we use caching for 1 minute to avoid unnecessary queries.
$query = \DB::table(\DB::raw('Products, (SELECT #row := 0) r'));
$query = $query->select(
\DB::raw('#row := #row + 1 AS SrNo'),
'ProductID',
'ProductName',
'Description',
\DB::raw('IFNULL(ProductImage,"") AS ProductImage')
);
// where clauses
if(...){
$query = $query->where('ProductID', ...));
}
// orderby clauses
// ...
// $query = $query->orderBy('..','DESC');
// count clause
$TotalRecordCount = $query->count();
$results = $query
->take(...)
->skip(...)
->get();
I believe you could use Raw Expresssions to achieve this:
$users = DB::table('users')
->select(DB::raw('ROW_NUMBER() OVER(ORDER BY ID DESC) AS Row, status'))
->where('status', '<>', 1)
->groupBy('status')
->get();
However, looking trough the source code looks like you could achieve the same when using SQLServer and offset. The sources indicates that if you something like the following:
$users = DB::table('users')->skip(10)->take(5)->get();
The generated SQL query will include the row_number over statement.
[For Postgres]
In your model
public function scopeWithRowNumber($query, $column = 'id', $order = 'asc'){
$sub = static::selectRaw('*, row_number() OVER () as row_number')
->orderBy($column, $order)
->toSql();
$query->from(DB::raw("({$sub}) as sub"));
}
In your controller
$user = User::withRowNumber()->get();
