Query bug on child models

[ozziest]

Let's assume that we have a model like this;

class StudentLesson extends Model {
  lesson() {
    return this.belongsTo("Lesson", "lesson_id", "id");
  }

  teacher() {
    return this.belongsTo("Teacher", "teacher_id", "id");
  }
}

When we request the following example, we don't use parentheses to group query features;

/api/students/1/lessons?q=[{ "$or.lesson.name.$like":"*a*"},{ "$or.teacher.name.$like":"*a*"}]

When we execute this request, it executes the following query;

where `student_id` = 1 and `lessons`.`name` like "%a%" or `teachers`.`name` like "%a%"

But, it should be like the following one;

where `student_id` = 1 and (`lessons`.`name` like "%a%" or `teachers`.`name` like "%a%")
