I'm having trouble getting a count based on a special condition.
Basically, a "completed competency" is one that receives an evaluation of 3 at least two times. The following code works for counting how many distinct competencies have an evaluation of 3, but I want it to only count them if the distinct competency_id has an evaluation of 3 at least twice in the database for the specified student. Any suggestions?
$completed_competencies = DB::table('submitted_competencies') ->where('student_id', 202) ->where('evaluation', 3) // I want this to happen twice for the same competency_id before it is counted. ->distinct('competency_id') ->count('competency_id');
