Question

I have a GAE Entity called MyFile

public class MyFile {  
   static enum LocationEnum {Folders, Hidden};  
   static enum FileType {File, Folder);  
   @Id private Long id;  
   private Key<MyFile> parent;  
   private String name;  
   private LocationEnum location;  
   private FileType fType;

   // getters and setters  
}  

And a function in a separate DAO class to query for files based on their parent, returning the results ordered by name.

public List<MyFile> getFiles(Key<MyFile> parent) {  
    Query<MyFile> q1 = ofy().query(MyFile.class).filter("parent", parent).filter("location", LocationEnum.Folders).order("name");  
    return q1.list();
}  

It seems my order is ignored as the results are returned ordered by id. It did occur to me that I was missing something to do with indexing, but I noticed GAE blessed me an auto generated index based on location, parent, name. So I thought it would just work.

How do I order by name?

Answer 1

I’ve found the problem. It is not possible to do a case insensitive search on App Engine. GAE will order by upper case first A-Z followed by a-z.
