How do I get a response based on two different IDs in my API?

public class Report
{
[Key]
public int ReportId { get; set; }

[ForeignKey("Subjects")]
public int SubjectId { get; set; }
public Subjects Subjects { get; set; }

[ForeignKey("Teacher")]
public int TeacherId { get; set; }
public Teacher Teacher { get; set; }

[ForeignKey("MarkType")]
public int MarkTypeId { get; set; }
public MarkType MarkType { get; set; }
}

public class Teacher
{
[Key]
public int TeacherId { get; set; }

[MaxLength(50)]
[Required]
public string FName { get; set; }

[MaxLength(50)]
[Required]
public string LName { get; set; }

}

public class Student
{
[Key]
public int StudentId { get; set; }

[MaxLength(50)]
[Required]
public string FName { get; set; }

[MaxLength(50)]
[Required]
public string LName { get; set; }

[ForeignKey("Grade")]
public int GradeId { get; set; }
public Grade Grade { get; set; }
}

public class Grade
{
[Key]
public int GradeId { get; set; }
public int StudentGrade { get; set; }
}

public class Subjects

public int SubjectId { get; set; }

[MaxLength(50)]
[Required]
public string SubjectName { get; set; }
}

public class Terms
{
[Key]
public int TermId { get; set; }

public int Term { get; set; }
}

public class MarkType
{
[Key]
public int MarkTypeId { get; set; }
[MaxLength(20)]
[Required]
public string TypeName { get; set; }

}

public class StudentMark
{
[Key]
public int StudentMarkId { get; set; }

[ForeignKey("Report")]
public int ReportId { get; set; }
public Report Report { get; set; }

[ForeignKey("Student")]
public int StudentId { get; set; }
public Student Student { get; set; }

public int Mark { get; set; }

[ForeignKey("Terms")]
public int TermId { get; set; }
public Terms Terms { get; set; }

}


In the API I am making I want to have the ability to use two different IDs to get a more specific response.



var report = ReportDBContext.StudentMark
.Include(p => p.Student.Grade).Include(p => p.Report)
.Include(p => p.Terms).Include(a => a.Report.Subjects).Include(a => a.Terms)
.Include(a => a.Report.MarkType).Include(a => a.Report.Teacher).ToList();


This allowed me to get StudentMark as well as it's related entities but I want to have the ability to use The student's Id and the Term's Id to get a student's marks for that term and all the subjects related to the student. I am a beginner to Web API so please let me know if I need to add more context.

If you want to query by either StudentId or TermId, I suggest that you provide two different endpoints for these two different queries. Use LINQ Where to check your conditions.



public StudentMark GetMarksByStudentId(int studentId) {
return ReportDBContext.StudentMark
/* .Include(...) */
.Where(mark => mark.StudentId == studentId)
.ToArray();
}

public StudentMark GetMarksByTermId(int termId) {
return ReportDBContext.StudentMark
/* .Include(...) */
.Where(mark => mark.TermId == termId)
.ToArray();
}


If you want to query by StudentId and TermId simultaneously, introduce a query object to encapsulate your parameters. You can test for multiple conditions in the Where clause with AND &&.



public StudentMark FindMarks(StudentMarkQuery query) {
return ReportDBContext.StudentMark
/* .Include(...) */
.Where(mark => mark.StudentId == query.StudentId
&& mark.TermId == query.TermId)
.ToArray();
}


The StudentMarkQuery class is introduced so you can add additional parameters without changing the overall signature of the endpoint:



public class StudentMarkQuery {
public int StudentId { get; set; }
public int TermId { get; set; }
}
