Laravel how to query with Auth ID from another table - laravel

Question

I have a forms_table where I query all my results for authenticated user with where Auth::id() in user_id column.
Each of these rows have a boolean column alternation. If this is 1, then it means there is a row in another table called form_alternation where I have the Auth::id(). This means the Auth::id() does not exist in the initial forms_table.
How can I retrieve the rows from the forms_table with where clause where('user_id', Auth::id()) and show the rows where the Auth::id() exists in the form_alternations?
Currently I have this and it shows me 0 rows because the last Auth::id() clause.
$baseQuery->with(['alternated' => function($q){
$q->where('user_id', Auth::id());
}]);
$baseQuery->where('user_id', Auth::id());

As i see it you want your query to do something similar to this (in half pseudo code).
where (forms.user.id = Auth::id() OR (users.alternation = 1 AND alternated.user_id = Auth::id()))
This could be achieved with Eloquent, as i understand your domain, try something like this.
use Illuminate\Database\Eloquent\Builder;
// wrap it in where, to avoid other queries precedence ruining the or clause
$query->where(function (Builder $query) {
// First part, where we assume user id is in forms
$query->where('user_id', Auth::id());
// Second part, check alternation or your relationship
$query->orWhere(function (Builder $query) {
$query->where('alternation', true);
// Use whereHas to check if your forms has the user as a relationship
$query->whereHas('alternated', function (Builder $query) {
$query->where('user_id', Auth::id());
});
});
});
This should provide similar logic to the pseudo example, simply utilizing orWhere() logic and you can check relationships with whereHas().
