I am trying to run a join query from my controller on laravel but i am getting "Call to a member function leftJoin() on null"
public function tracking_groupindividual(Request $request)
{
$user_id = $request->user_id;
$group_id = $request->group_id;
$get_group_individual_details = DB::table('group_usermapping as gu')
->select(
'um.user_id',
'um.user_name',
'um.image_path',
'um.mobile_number',
'ul.latitude',
'ul.longitude',
'um.isnearby_on',
'gu.isadmin',
'um.profile_status',
'ul.timedout'
)
->join('user_master as um','gu.user_id','=','um.user_id')
->join('groupusers_location as ul','ul.user_id','=','um.user_id','ul.group_id','=','gu.group_id')
->where(function ($query) use ($group_id) {
$query->where('gu.group_id', '=', $group_id)
->where('gu.isactive','=','1')->where('um.isactive','=','1');
})->get();
return $get_group_individual_details;
}
I found a problem in the second join and fixed it
public function tracking_groupindividual(Request $request)
{
$user_id = $request->user_id;
$group_id = $request->group_id;
$get_group_individual_details = DB::table('group_usermapping as gu')
->select(
'um.user_id',
'um.user_name',
'um.image_path',
'um.mobile_number',
'ul.latitude',
'ul.longitude',
'um.isnearby_on',
'gu.isadmin',
'um.profile_status',
'ul.timedout'
)
->join('user_master as um','gu.user_id','=','um.user_id')
->join('groupusers_location as ul', function ($join) {
$join->on('ul.user_id','=','um.user_id')
->where('ul.group_id','=','gu.group_id');
})
->where(function ($query) use ($group_id) {
$query->where('gu.group_id', '=', $group_id)
->where('gu.isactive','=','1')->where('um.isactive','=','1');
})->get();
return $get_group_individual_details;
}
try to use DB::raw() with aliases!!!
$get_group_individual_details = DB::table(DB::raw('group_usermapping as gu'))
->join(DB::raw('user_master as um'),DB::raw('gu.user_id'),'=',DB::raw('um.user_id'))
->join(DB::raw('groupusers_location as ul'),DB::raw('ul.user_id'),'=',DB::raw('um.user_id'),DB::raw('ul.group_id'),'=',DB::raw('gu.group_id'))
->select(DB::raw('um.user_id'),DB::raw('um.user_name'),DB::raw('um.image_path'),DB::raw('um.mobile_number'),DB::raw('ul.latitude'),DB::raw('ul.longitude'),DB::raw('um.isnearby_on'),DB::raw('gu.isadmin'),DB::raw('um.profile_status'),DB::raw('ul.timedout'))
->where(function ($query) use ($group_id) {
$query->where(DB::raw('gu.group_id'), '=', $group_id)->where(DB::raw('gu.isactive'),'=','1')->where(DB::raw('um.isactive'),'=','1');
})->get();
return $get_group_individual_details;
and replace use Illuminate\Support\Facades\DB; with use DB;

I have this query:
$result = PortingItem::whereHas('porting', function ($query) {
$query->whereIn('status', [
Porting::STATUS_REQUESTED,
Porting::STATUS_ACCEPTED,
Porting::STATUS_DELAYED,
]);
})->where(function ($query) use ($numbers) {
$query->whereBetween('phone_number_start', [$numbers[0], $numbers[1]])
->orWhereBetween('phone_number_end', [$numbers[0], $numbers[1]]);
})->orWhere([
['phone_number_start', '<=', $numbers[0]],
['phone_number_end', '>=', $numbers[1]],
])->get();
The PortingItem model still returns the query result while the porting relation is empty. I don't understand why this happens.
This is my Porting model relation
public function items()
{
return $this->hasMany(PortingItem::class);
}
This is my PortingItem model relation:
public function porting()
{
return $this->belongsTo(Porting::class);
}
You should always group orWhere calls in order to avoid unexpected behavior when global scopes are applied.
$result = PortingItem::whereHas('porting', function ($query) {
$query->whereIn('status', [
Porting::STATUS_REQUESTED,
Porting::STATUS_ACCEPTED,
Porting::STATUS_DELAYED,
]);
})->where(function ($query) use ($numbers) {
$query->where(function ($query) use ($numbers) {
$query->whereBetween('phone_number_start', [$numbers[0], $numbers[1]])
->orWhereBetween('phone_number_end', [$numbers[0], $numbers[1]]);
})->orWhere(function ($query) use ($numbers) {
$query->where('phone_number_start', '<=', $numbers[0])
->where('phone_number_end', '>=', $numbers[1]);
});
})->get();

I'm trying to make search function with relation.
I could display all result using relation And an another code, simple one table search and get result works fine.
but I can't combine those two.
Could you teach me how to combine multiple tables into search function please?
public function order(Request $request)
{
$data = $request->all();
$products = Product::All();
$products = Product::with('categori')
->join('creators', 'creators.id', '=', 'products.creator_id')
->join('categoris', 'categoris.id', '=', 'products.categori_id')
->join('branches', 'branches.id', '=', 'products.br_id')
->join('users', 'users.id', '=', 'products.user_id')
->join('colors', 'colors.id', '=', 'products.color_id')
->get();
$products = Product::when($data['categori_id'], function ($query, $categori_id) {
return $query->where('categori_id', $categori_id);
})->
when($data['color_id'], function ($query, $color_id) {
return $query->where('color_id', $color_id);
})->get();
//return view('result_fb', compact('images'));
$data = array(
'title' => 'index',
'no' => 1,
'products' => $products,
);
return view('product.result', $data);
}
I am not sure if you need 'categori' relation to be loaded or not as there are few $products without it. For general, you can combine all your $products queries to one as follows:
$products = Product::join('creators', 'creators.id', '=', 'products.creator_id')
->join('categoris', 'categoris.id', '=', 'products.categori_id')
->join('branches', 'branches.id', '=', 'products.br_id')
->join('users', 'users.id', '=', 'products.user_id')
->join('colors', 'colors.id', '=', 'products.color_id')
->when($data['categori_id'], function ($query, $categori_id) use ($data) {
return $query->where('categori_id', $data['categori_id']);
})
->when($data['color_id'], function ($query) use ($data) {
return $query->where('color_id', $data['color_id']);
})->get();
If you want to use eager loading with eloquent rather then join, you can use like
$products = Product::with(['creator','categori','branch','user','color'])
->when($data['categori_id'], function ($query, $categori_id) use ($data) {
return $query->where('categori_id', $data['categori_id']);
})
->when($data['color_id'], function ($query) use ($data) {
return $query->where('color_id', $data['color_id']);
})->get();
But for that you Product model should have relations with same name as follows for categori relation:
class Product extends Model
{
public function categori()
{
return $this->belongsTo(Categori::class,'categori_id','id);
}
}
Same way you have to define for all relation used for product.
Try this:
$products = Product::with('categori')
->join('creators', 'creators.id', '=', 'products.creator_id')
->join('categoris', 'categoris.id', '=', 'products.categori_id')
->join('branches', 'branches.id', '=', 'products.br_id')
->join('users', 'users.id', '=', 'products.user_id')
->join('colors', 'colors.id', '=', 'products.color_id')
->when($data['categori_id'], function ($query, $categori_id) {
return $query->where('categori_id', $categori_id);
})
->when($data['color_id'], function ($query, $color_id) {
return $query->where('color_id', $color_id);
})
->get();
I have a WorkPackage model with below relationship.
public function work_items()
{
return $this->hasMany(WorkItem::class);
}
And WorkPackage has 'title','project_id' columns and work_items has 'title','work_package_id' columns. Now I want to search user typed keyword is matching with title in both table.
Here is my tried function
public function getWorkPackageProposals($projectId, $title)
{
$result['data'] = $this->workPackage->with(['work_items' => function ($query) {
$query->where('title', 'LIKE', "%{$title}%");
}])
->where('project_id', $projectId)
->where('title', 'LIKE', "%{$title}%")
->get();
return $result;
}
but its not working.
Please find the below code for I used to create object of WorkPackage.
public function __construct(WorkPackage $workPackage)
{
$this->workPackage = $workPackage;
$this->setModel(WorkPackage::class);
$this->workItemRepository = app(WorkItemRepository::class);
}
whereHas() works to specify additional filters for the related model to check :
$result['data'] = $this->workPackage->whereHas('work_items', function ($query) use ($title) {
$query->where('title', 'LIKE', "%{$title}%");
})
->where('project_id', $projectId)
->where('title', 'LIKE', "%{$title}%")
->get();
return $result;
Below code works for me. Thanks to everyone for help to get right answer.
$result['data'] = $this->workPackage->with(['work_items' => function ($q) use ($title) {
$q->where('title', 'LIKE', "%{$title}%");
}])
->where('project_id', $projectId)
->where('title', 'LIKE', "%{$title}%")
->get();
return $result;
I think your problem will be solved with join method:
$result = $this->workPackage
->join('work_items', 'work_packages.id', '=', 'work_items.package_id')
->where('work_items.title', 'LIKE', '%{$term}%')
->orWhere('work_packages.title', 'LIKE', '%{$term}%')
->get();
I'm new with laravel. I can't use $class _id in a function whereHas. What should I do?
public function show($classroom_id)
{
$classrooms = Group::whereHas('members', function ($query) {
$query->where([['user_id', '=', Auth::id()], ['classroom_id', $classroom_id]]);
})->get();
return response()->json($classrooms);
}
See use (classroom_id)
$groups = Group::whereHas('natures', function($q) use($classroom_id)
{
$q->where('classroom_id', '=', $classroom_id);
});
I have the following relations in my Laravel application
class Item extends Model
{
public function category()
{
return $this->belongsTo('App\Category');
}
}
and
class Category extends Model
{
public function item()
{
return $this->hasMany('App\Item');
}
}
I want to implement search functionality so I have created the following Eloquent query:
$items = Item::where('item_type', '=', 'type1')
->where(function($query) use ($q) {
$query->where('item_name','LIKE','%'.$q.'%')
->orWhere('item_description','LIKE','%'.$q.'%');
})
->paginate(10);
This is working as expected and returns the search results for 'q' based on the name and the description of the item.
As a next step, I would like to also search for the category_name. Because of the relation, I have the category_id stored in the Items table, but I would like to use the category_name in my Eloquent query.
Anyone could provide some help?
Based on feedback received, I tried:
Suggestion 1:
$items = Item::where('item_type', '=', 'type1')
->where(function($query) use ($q) {
$query
->where('item_name', 'LIKE' ,'%'.$q.'%')
->orWhere('item_description', 'LIKE' ,'%'.$q.'%');
})
->whereHas('category', function (Category $query) use ($q) {
$query->where('category_name', $q);
})
=> this gives following error message:
Argument 1 passed to
App\Http\Controllers\ItemController::App\Http\Controllers{closure}()
must be an instance of App\Http\Controllers\App\Category, instance of
Illuminate\Database\Eloquent\Builder given
Suggestion 2:
$items = Item::where('item_type', '=', 'type1')
->where(function($query) use ($q) {
$query
->where('item_name', 'LIKE' ,'%'.$q.'%')
->orWhere('item_description', 'LIKE' ,'%'.$q.'%');
})
->whereHas('category', function ($query) use ($q) {
$query->where('category_name', $q);
})
=> this does not result any search result anymore (also not for item_name and item_description).
Solution
$items = Item::where('item_type', '=', 'type1')
->where(function($query) use ($q) {
$query
->where('item_name', 'LIKE' ,'%'.$q.'%')
->orWhere('item_description', 'LIKE' ,'%'.$q.'%');
})
->orWhereHas('category', function ($query) use ($q) {
$query->where('category_name', $q);
})
->sortable(['id' => 'desc'])
->paginate(10);
As you already described relation to Category in your Item model, you have to use just whereHas method:
$items = Item::where('item_type', '=', 'type1')
->where(function($query) use ($q) {
$query->where('item_name','LIKE','%'.$q.'%')
->orWhere('item_description','LIKE','%'.$q.'%');
})
->orWhereHas('category', function ($query) use ($q) {
$query->where('category_name', 'LIKE', "%$q%");
})
->paginate(10);
You could add a whereHas and constrain it. For example:
$items = Item::where('item_type', '=', 'type1')
->where(function($query) use ($q) {
$query->where('item_name','LIKE','%'.$q.'%')
->orWhere('item_description','LIKE','%'.$q.'%');
})
->whereHas('category', function($query) {
$query->where('category_name', 'name');
})
->paginate(10);
