$modules = Role::with(['rights' => function ($q) {
return $q->with('module');
}])->where('id', $user->role_id)->get();
Can someone help with this condition not working with the where statement?
You can not return inside the relation inside the with() closure.
Instead, you can use Nested Eager Loading for this.
$modules = Role::where('id', $user->role_id)
->with('rights.module')
->get();

I am new to laravel,
I need to create a query for the db,
$query = Deal::query();
I want to use the wherehas operator.
this is my code that is worked.
else if ($group_by == 'precedence') {
if($get_deals_for == 'noprecedence'){
$get_deals_for = 0;
}
$precedenceStatus = $get_deals_for;
$query-> where('precedence', '=', $precedenceStatus);
// \Log::info('The request precedence: '.$precedenceStatus);
}
I want to add this code also to the query
if($person) {
$query->whereHas('personnel', function ($subQuery) use ($person) {
$subQuery->where('id', '=', $person);
});
}
So I need to change the first code?
how I can convert the first code to wherehas?
the first code is from table called deal, the second section is from realtionship called personnel.
the second section worked in other places in the code, I just need to fix the first section and not understand what to write in the use
I try this and get error on the last }
else if ($group_by == 'precedence') {
if($get_deals_for == 'noprecedence'){
$get_deals_for = 0;
}
$precedenceStatus = $get_deals_for;
$query-> where('precedence', '=', $precedenceStatus)
-> when ($person, function($query) use($person) {
$query->whereHas('personnel', function ($query) use ($person) {
$query->where('id', '=', $person);
});
})
}
There is a method you can use called when(, so that you can have cleaner code. The first parameter if true will execute your conditional statement.
https://laravel.com/docs/9.x/queries#conditional-clauses
$result = $query
->where('precedence', '=', $precedenceStatus)
->when($person, function ($query) use ($person) {
$query->whereHas('personnel', fn ($q) => $q->where('id', '=', $person));
})
->get();
You should also be able to clean up your precedence code prior to that using when( to make the entire thing a bit cleaner.
Querying to DB is so easy in laravel you just need to what you want what query you want execute after that you just have to replace it with laravel helpers.Or you can write the raw query if you cant understand which function to use.
using,DB::raw('write your sql query').
Now Most of the time whereHad is used to filter the data of the particular model.
Prefer this link,[Laravel official doc for queries][1] like if you have 1 to m relation ship so u can retrive many object from one part or one part from many object.like i want to filter many comments done by a user,then i will right like this.
$comments = Comment::whereHas('user', function (Builder $query) {
$query->where('content', 'like', 'title%');
})->get();
$comments = Here will be the model which you want to retrive::whereHas('relationship name', function (Builder $query) {
$query->where('content', 'like', 'title%');
})->get();
you can also write whereHas inside whereHas.

I am new to the laravel, i am joining three tables based on conditions every thing is working fine but i need to write conditionally if the $field is array it should run with whereIn otherwise it should run where condition,can you please help me to acheive this thing
//$field sometimes it's an array sometimes it's a string.
public function find($field){
}
For conditional constraints, you can use the when() clause:
$query = DB::table(...);
$data = $query
->when(is_array($field), function ($query) use ($field) {
$query->whereIn('my_field', $field);
}, function ($query) use ($field) {
$query->where('my_field', $field);
})
->get();
Now, as a tip, you could do this: Wrap the $fields variables to an array and then use always the whereIn clause. You can achieve this with the Arr::wrap() function:
use Illuminate\Support\Arr;
// ...
$query = DB::table(...);
$data = $query
->whereIn('my_field', Arr::wrap($field))
->get();
PS: I have linked the relevant functions to the docs so you can know how they work and their params.
Why in Eloquent a simple query as this one is not working?
$matches = DB::table("matches")
->where(["team_a"=> $request->tid, "match_tipo"=>3])
->orWhere(["team_a"=> $request->tid, "match_tipo"=>3])
->first();
According to with other examples here on Stackoverflow, I should use a query in Where like:
$matches = DB::table("matches")
->where(["match_tipo"=>3])
->where(function($query, $request) {
$query->where('team_h',$request->tid)
->orWhere('team_a',$request->tid);
})
->first();
But I should pass a second parameter ($request).
How is the simplest way to do this query?
You can make this as like this.
->where(["match_tipo"=>3]) this will be ->where("match_tipo",3) and use($tid) after query.
$tid = $request->tid;
$matches = DB::table("matches")
->where("match_tipo",3)
->where(function($query) use($tid) {
$query->where('team_h',$tid)
->orWhere('team_a',$tid);
})
->get();
while using the Callback or Closure as the where function Parameter you will only the one argument which is Current Object
Methods Can used to Pass the $request
Method One
$matches = DB::table("matches")
->where(["match_tipo"=>3])
->where(function($query) use ($request) {
$query->where('team_h',$request->tid)
->orWhere('team_a',$request->tid);
})
->first();
Method Two
$matches = DB::table("matches")
->where('match_tipo','=',3)
->when($request->tid,function($query) use ($request) {
return $query->where('team_h',$request->tid)
->orWhere('team_a',$request->tid);
})
->first();
Try this query :
$matches = DB::table("matches")
->where('match_tipo',3)
->whereRaw('team_a = "'.$request->tid.'" OR team_h = "'.$request->tid.'"')
->first();
$institutes = Institute::with(['address' => function($query){
$query->whereCityId(Input::get('city_id'));
$query->whereIn('area_id',Input::get('area_id'));
}])->get();
Invalid argument supplied for foreach()
The problem could be here
$query->whereIn('area_id',Input::get('area_id'));
Try to ensure that Input::get('area_id') actually returns an array:
$area = Input::get('area_id') ?: [];
$query->whereIn('area_id',is_string($area) ? json_decode($area, true) : $area);
is whereCityId the scope of the model? Documentation has examples with scopes chained with models only.
Try replacing the scope with column name and try. ex replaced with city_id
$institutes = Institute::with(['address' => function($query){
$query->where('city_id',Input::get('city_id'));
$query->whereIn('area_id',Input::get('area_id'));
}])->get();
It does work but it returns
address: null
wherever the condition matches. But it returns all institutes. Either we can use filter on the collection or whereHas
$institutes = Institute::whereHas('address', function ($query) use ($city_id) {
$query->whereCityId($city_id);
})->get();
or
$institutes = Institute::with(['address' => function ($query) use ($city_id) {
$query->whereCityId($city_id);
}])->get()->filter(function ($institute){
return $institute->address != null;
});
I have the following relationship functions in my Job model:
public function resourceTypes(){
return $this->belongsToMany('ResourceType', 'job_requests');
}
public function resources(){
return $this->belongsToMany('Resource', 'jobs_resources')->withPivot('flow_type', 'resource_type_id');
}
I am able to get an object with data from both of the above relationships using:
$job = Job::findorfail($projectId);
$result = $job->with('resources.resourceTypes')->get();
I would like to put a where clause on the jobs_resources pivot table - specifically on the column flow_type.
How would I do this?
Try something like this:
$job = Job::with('resources' => function($q) {
$q->with('resourceTypes')->where('flow_type',2);
})->findorfail($projectId);
In above you will get only those resources with flow_type = 2
I ended up using the following statement:
Job::with(['resources' => function ($query){
$query->wherePivot('flow_type', '=', '1' );
}, 'resources.resourceTypes'])->where('id', $projectId)->firstOrFail();
$result = DB::table('job')
->join('job_resources', 'job.id', '=', 'job_resources.job_id')
->join('job_requests', 'job_resources.request_id', '=', 'job_requests.id')
->where('job_resources.flow_type', '=', CONDITION)
->get();
Your table data is not clear from your input, but this method (query builder) should work
