I want to join multiple tables in laravel with query builder. My problem is that my code only works if I specify the id myself that I want like this:
$datauser = DB::table('users')
->join('activitates','users.id','=','activitates.user_id')
->join('taga_cars','taga_cars.id','=','activitates.tagacar_id')
->join('clients','users.id','=','clients.user_id')
->where('users.id','=','1')
->select('users.*','activitates.*','taga_cars.model','taga_cars.id','clients.name')
->get();
return response()->json($datauser);
But I would want something like this(which I just can't seem to figure out)
public function showuser($id)
{
$userid = User::findOrFail($id);
$datauser = DB::table('users')
->join('activitates','users.id','=','activitates.user_id')
->join('taga_cars','taga_cars.id','=','activitates.tagacar_id')
->join('clients','users.id','=','clients.user_id')
->where('users.id','=',$userid)
->select('users.*','activitates.*','taga_cars.model','taga_cars.id','clients.name')
->get();
return response()->json($datauser);
}
Am I making a syntax mistake? When I check the page for my json response in second page it just returns empty brackets, but when I specify the id it fetches me the right data
The findOrFail method will return the entire user model, with all its properties, since you already have the user id. You dont need to get the entire user model for that, you could just use the $id you receveid as a parameter like this:
$datauser = DB::table('users')
->join('activitates','users.id','=','activitates.user_id')
->join('taga_cars','taga_cars.id','=','activitates.tagacar_id')
->join('clients','users.id','=','clients.user_id')
->where('users.id','=',$id)
->select('users.*','activitates.*','taga_cars.model','taga_cars.id','clients.name')
->get();
return response()->json($datauser);
public function showuser($id)
{
$getUserByID = User::findOrFail($id); //not used
$userData = DB::table('users')
->join('activitates','users.id','=','activitates.user_id')
->join('taga_cars','taga_cars.id','=','activitates.tagacar_id')
->join('clients','users.id','=','clients.user_id')
->where('users.id','=',$id)
->select('users.*','activitates.*','taga_cars.model','taga_cars.id','clients.name')
->get();
return response()->json($userData);
}
But the best way is to have relations set on models
public function showuser($id)
{
$userData = User::where('id', $id)->with(['activitates','taga_cars','clients'])->first();
return response()->json($userData);
}
In my laravel-application, I want to display all users/candidates, which have taken an education. Now it might happen, that a user/candidate has taken more than one education, so in this case, just the latest education should be displayed.
I've come to this:
$users = User::whereHas('roles', function ($q) {
$q->where('slug', 'candidate');
}
)->whereHas('educations')
->join('user_educations', 'user_educations.user_id', '=', 'users.id')
->join('educations', 'user_educations.education_id', '=', 'educations.id')
->join('education_levels', 'user_educations.education_level_id', '=', 'education_levels.id')
->select('users.id', 'users.name', 'users.surname', 'users.status', 'users.city', 'users.zipcode', 'users.birthday', 'users.avatar', 'educations.title as education', 'education_levels.title as education_level')
->where('user_educations.user_id', '=', 'users.id') // HERE IT FAILS - returns null
->first();
return response(['success' => true, "users" => $users], 200);
when I leave out the where('user_educations.user_id', '=', 'users.id')-clause, and do get() instead of first(), I get all users/candidates with educations, and also sometimes the same user multiple times, depending on how many educations he has taken.
how can I fix this?
The distinct method allows you to force the query to return distinct results, you can use it like this;
$users = DB::table('users')->groupBy('user_id')->distinct()->get();
If you want to take just the latest record, you should use "orderBy" to order your records, than pick a record with something like this :
$users = DB::table('users')->groupBy('user_id')->orderBy('created_at','desc')->distinct()->get();
You can look here for more detailed information about query builders in Laravel
I have a query built where I'm using "with" to include related models. However, I'm not sure how to filter those related models in a where clause.
return \App\Project::with("projectLeaders")->join('companies', 'company_id', '=', 'companies.id')
->join('project_status', 'project_status.id', '=', 'projects.status_id')
->select('companies.*', 'project_status.name AS statusName', 'projects.*');
Please note the with("projectLeaders") in the query. So, ProjectLeaders is a relation that brings objects of kind Employee, how can I filter in that query those "Employees" whose attribute "Lastname" is like "Smith" ?
You can implement where class both tables. Please check following code and comments.
return \App\Proyecto::with(["projectLeaders" => function($query){
$query->where() //if condition with inner table.
}])->join('empresas', 'id_empresa', '=', 'empresas.id')
->join('tipo_estado_proyecto', 'tipo_estado_proyecto.id', '=', 'proyectos.id_tipo_estado_proyecto')
->where() //if condition with main table column.
->select('empresas.*', 'tipo_estado_proyecto.nombre AS nombreEstadoProyecto', 'proyectos.*');
You can use Closure when accessing relation using with. Check below code for more details:
return \App\Project::with(["projectLeaders" => function($query){
$query->where('Lastname', 'Smith') //check lastname
}])->join('companies', 'company_id', '=', 'companies.id')
->join('project_status', 'project_status.id', '=', 'projects.status_id')
->select('companies.*', 'project_status.name AS statusName', 'projects.*');
You may use the where method on a query builder instance to add where clauses to the query. The most basic call to where requires three arguments. The first argument is the name of the column. The second argument is an operator, which can be any of the database's supported operators. Finally, the third argument is the value to evaluate against the column.
return \App\Project::with("projectLeaders")->join('companies', 'company_id', '=', 'companies.id')
->join('project_status', 'project_status.id', '=', 'projects.status_id')
->where('lastname','=','Smith')
->select('companies.*', 'project_status.name AS statusName', 'projects.*');
Don't forget to return results with a get();
The query you have written is correct. But after building the query you need to fetch the data from database.
METHOD ONE
So adding get() method to your query:
return App\Project::with('projectLeaders')
->leftJoin('companies', 'company_id', '=', 'companies.id')
->leftJoin('project_status', 'project_status.id', '=', 'projects.status_id')
->select('companies.*', 'project_status.name AS statusName', 'projects.*')
->get();
METHOD TWO (with pagination)
return App\Project::with('projectLeaders')
->leftJoin('companies', 'company_id', '=', 'companies.id')
->leftJoin('project_status', 'project_status.id', '=', 'projects.status_id')
->select('companies.*', 'project_status.name AS statusName', 'projects.*')
->paginate(3);
why my code get error
public function AuditorBagian_Edit($nopek)
{
$user = User::where('nopek', '=', $nopek)->get();
$bagian_user = Bagian::all()->where('kode_bagian', '=', $user->bagian)->get();
return response()->json($bagian_user);
}
I want to show data from Bagian
You can pass collection or array into response()->json() function it will convert as JSON data
public function AuditorBagian_Edit($nopek)
{
$user = User::where('nopek', '=', $nopek)->get();
$bagian_user = Bagian::where('kode_bagian', '=', $user->bagian)->get();
// or $bagian_user = Bagian::where('kode_bagian', '=', $user->bagian)->get()->toArray();
return response()->json($bagian_user);
}
Error result of code
$bagian_user = Bagian::all()->where('kode_bagian', '=', $user->bagian)->get();
Bagian::all() return instance of Illuminate\Database\Eloquent\Collection and find all records in db, then you try to filter ->where('kode_bagian', '=', $user->bagian)->get() specific records but this code wrong because method where() of Illuminate\Database\Eloquent\Collection class return instance of Illuminate\Database\Eloquent\Collection and this class does not haveget() method.
User::where('nopek', '=', $nopek)->get() also return instance of Illuminate\Database\Eloquent\Collection. To get single record use first() method instead of get()
The correct way get result is
$user = User::where('nopek', '=', $nopek)->first();
if(!empthy($user)) {
$bagian_user = Bagian::where('kode_bagian', '=', $user->bagian)->get().
}
Edited, format php code
Just remove the ::all() will do, all() and get() is the same behaviour.
Take not that all(), get(), first() is the final step to get the model data, the condition and with() and ordering() and etc must happen before all the three above mentioned
I have a contents table with a lot of contents created by different users… I’m trying to verify if a content is created by the user that is logged in and then add a new key value pair to the response, so if the content was created by user_id 1 and I’m user 1 then the response has a field like isOwn : 1 on the content object that is his own, but nothing if the content was created by someone else.
this is the criteria I have:
$query = $model->select('contents.*', 'status_types.name as status', 'content_types.name as content_type')
->join('status_types', 'status_types.id', '=', 'contents.status_type_id')
->join('content_types', 'content_types.id', '=', 'contents.content_type_id')
->with('platforms')
->with('classifications')
->withCount(['favorite' => function ($q) {
$q->where('user_id', '=', $this->request->user()->getIdentifier());
}])
->withCount('likes')
->inRandomOrder();
return $query;
I've tried to use when and whereExist but this return me only the ones created by the user, not if the condition is true.
Any ideas? thanks in advance.
You need to join on the model and make a where for the total query:
$query = $model->select('contents.*', 'status_types.name as status', 'content_types.name as content_type')
->join('status_types', 'status_types.id', '=', 'contents.status_type_id')
->join('content_types', 'content_types.id', '=', 'contents.content_type_id')
->join('favorites', 'favorites.contents_id', '=', 'contents.id') // or whatever the relation is
->with(['platforms', 'classifications'])
->withCount(['favorite'])
->withCount('likes')
->where('favorites.user_id', '=', $this->request->user()->getIdentifier())
->inRandomOrder();
return $query;
