Fetch list of forms that are belong to a specific student-CodePudding

I have a class of Form and Student. A student may have 0 or many forms. I set the relation between them as OneToMany. Now, I need to fetch the forms that are owned by a specific student. I have two questions at that point. How should I fetch those forms in the URL? Let's say I want to fetch the forms of the student with id=7.

Option 1:

api/v1/forms?studentId=7

Option 2:

api/v1/students/7/forms

Which one of them is most used or more reasonable? The second problem is that. Normally, when I want to add a new method to the JpaRepo. I just need to add the method that is served by Jpa such that findAll, findByStudentId. Since I have a list of forms in the Student entity/model. How can I fetch all the forms? Which named method should I use? To sum up, I need to know whether I should write the method in FormDataAccess or StudentDataAccess. And what should be the method name?

Student

@Data
@Entity
@Table(name = "student")
public class Student {
    @Id
    @Column(name = "Student_id")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;

    @Column(name = "Student_name")
    private String name;
    @Column(name = "Course_id")
    private int courseID;
    @Column(name="Oasis_id")
    private Long oasisID;

    @OneToMany(mappedBy = "student",fetch = FetchType.LAZY)
    @JsonIgnore
    private List<Form> forms;
}

Form Model

@Data
@Entity
@Table(name="form")
public class Form {

    @Id @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;

    @ManyToOne
    @JoinColumn(name = "Student_id", nullable = false)
    private Student student;

    @ManyToOne
    @JoinColumn(name = "Attending_id", nullable = false)
    private AttendingPhysician attending;
    @Column(name = "Kayit_no", nullable = false)
    private String kayitNo;

    @Column(name = "Staj_turu", nullable = false)
    private String stajTuru;

    @Column(name = "Yas", nullable = false)
    private int yas;

    @Column(name = "Cinsiyet", nullable = false)
    private String cinsiyet;

    @Column(name = "Sikayet", nullable = false)
    private String sikayet;

    @Column(name = "Ayirici_tani", nullable = false)
    private String ayiriciTani;

    @Column(name = "Kesin_tani", nullable = false)
    private String kesinTani;

    @Column(name = "Tedavi_yontemi", nullable = false)
    private String tedaviYontemi;

    @Column(name = "Etkilesim_turu", nullable = false)
    private String etkilesimTuru;

    @Column(name = "Kapsam", nullable = false)
    private String kapsam;

    @Column(name = "Gerceklestigi_ortam", nullable = false)
    private String gerceklestigiOrtam;

    @Column(name = "Status", nullable = false)
    private String status;

    @Column(name="Date_sent", nullable = false)  // Convert to timestamp using java Date @CreationTimestamp, @UpdateTimestamp
    private String dateSent;



}

CodePudding user response：

The solution is really simple.

I just need to write a query in my FormDataAccess.

@Query(" from Form where student.id = :studentId")
List<Form> findFormByStudentId(int studentId);

now I can retrieve the forms using this path

api/v1/forms/student/7

I still wonder how to retrieve the forms from the Student side, not Form side such that

api/v1/student/7/forms
