Developing ERP system for schools. So i have SCHOOL Schema and inside which i have referenced COURSE Schema. What i wanted to do is to have some fields inside COURSE schema unique like course name inside particular school. But if i mark the fields unique in schema itself it will cause problems.
One school can have multiple courses but the name of courses should be unique for that particular school. But two different schools can have courses with same name. eg:- school A has btech so school A can’t have other course document with same name but school B can have course with the name btech.
If i make the course_name field unique in schema itself i can’t add course_name which has been added in some other school already.
I can make this happen by fetching the db and then checking the course_name one-by-one. But i think that would not be the ideal solution.
Please let me know of some better solutions
//SCHOOL SCHEMA
const SchoolSchema =
mongoose.Schema({
course:
[{
type: mongoose.Schema.Types.ObjectId,
ref: 'course'
}]
})
//Course Schema
const CourseSchema =
mongoose.Schema({course_name: {
type: String,
}
