Is there a better way to join query in laravel eloquent.? - mysql

Question

I have two tables and both have separate models from them. first table is users and other table is users_details table I am writing an eloquent query to join the result but I am getting following error
Integrity constraint violation: 1052 Column 'gender' in where clause is ambiguous (SQL: select count(*) as aggregate from `users_details` right join `users` on `users_details`.`user_id` = `users`.`id` where `gender` LIKE female and `matrimonial` LIKE 1)
my code for the query is following.
public function bride(){
$query = app(UserDetail::class)->newQuery();
$query= $query->where('gender','LIKE','female');
$query= $query->where('matrimonial','LIKE','1');
$query = $query->rightJoin('users','users_details.user_id','=','users.id');
$request = request();
if(request()->exists('sort')){
$sorts = explode(',',request()->sort);
foreach ($sorts as $sort){
list($sortCol, $sortDir) = explode('|',$sort);
$query = $query->orderBy($sortCol,$sortDir);
}
}
else {
$query = $query->orderBy('id','asc');
}
if($request->exists('filter')) {
$query->where(function($q) use($request){
$value = "%{$request->filter}%";
$q->where('name','like',$value)
->orWhere('father_name','like',$value)
->orWhere('city','like',$value)
->orWhere('mother_name','like',$value);
});
}
$per_page = request()->has('per_page')?(int) request()->per_page : null;
$pagination = $query->paginate($per_page);
$pagination->appends([
'sort'=>request()->sort,
'filter'=>request()->filter,
'per_page'=>request()->per_page
]);
return response()->json(
$pagination
)
->header('Access-Control-Allow-Origin','*')
->header('Access-Control-Allow-Methods','GET');
}
What should I do to get the result. Thanks

Answer 1

Because there are same column name in your tables(gender in user_details and users), you need to specify the table name with the column, so that mysql can find the true column for you,
like this:
$query= $query->where('user_details.gender','LIKE','female');

Answer 2

SQL doesn't know which table you are talking about when you are using Joins - unless you specify table names for each column mentioned in your query.
Replace these lines:
$query= $query->where('gender','LIKE','female');
$query= $query->where('matrimonial','LIKE','1');
with these lines:
$query= $query->where('users_details.gender','LIKE','female');
$query= $query->where('users_details.matrimonial','LIKE','1');
