I have a problem with getting userId and another attributes to save and persist in my database, like auditing actions and save createdBy and modifiedBy in database before save or update any bean, I found helpful answers for createdBy and modifiedBy in this question : Is it possible to use @PrePersist and @PreUpdate with eBean and Play! 2.0? :
This is my class :
@MappedSuperclass
public abstract class BaseModel extends Model {
@Id
@Column
@GeneratedValue(strategy=GenerationType.AUTO)
public Integer id;
@Column
@CreatedTimestamp
public Timestamp createdDate;
@Column
@UpdatedTimestamp
public Timestamp updatedDate;
@Column
@Version
private long version=0;
@Column
public String updatedBy;
@Column
public String createdBy;
public BaseModel() {
}
@Override
public void save() {
boolean isInstanceOfAccount = this instanceof Account;
if (!isInstanceOfAccount) {
int userId = Integer.parseInt(session().get(ViewModelsConstants.User.USER_ID);
updatedBy = String.valueOf(userId);
// etc to
}
super.save();
}
}
You can note that i have override the save method (so i'll do to update) so when I call my bean like product.save() I save the id for who did that add or update. but I have a similar unanswered issue to Session inside Model in play framework,
I maybe can add method have parameters to save and call super like :
public void save(int userId) {
boolean isInstanceOfAccount = this instanceof Account;
if (!isInstanceOfAccount) {
updatedBy = String.valueOf(userId );
// etc to
}
super.save();
}
But I have already exist code and I don't want to do modification in all my classes, and if I want to add more or remove parameters I need then to refactor
What the coolest (best practice) solution for this?
My Simple stupid question now : how I can pass from session to model OR how i can save parameter (like userId when he login) somewhere to use in model when I save or update it?
