PATCH REST call and default some entity columns [DATAREST-1534]

snehi23 opened DATAREST-1534 and commented

I build my REST api around Oracle entities using spring data rest. 
With the use case of updating only one entity field, I am using PATCH url.
This entity has some columns which needed to be defaulted at every update (or patch to be specific) call. For example :

  @UpdateTimestamp

  @Column(name = "LAST_UPDATED_DATE")

  private Date lastUpdatedDate;

 
@Column(name = "LAST_UPDATED_BY")

  private String lastUpdatedBy = "XXXX";

But setting up defaults is not working for field lastUpdatedBy

If I use PUT url and provide all column values except those set to default, it is updating as expected.
But I was wondering why there is no support for PATCH like that.
