[GAE] FileUpload in the Siena CRUD admin generator

[Nicolas]

Hello,

I use GAE and siena-crud for my Play! application. Do you know how to
have a FileUpload field in the admin controller of my model class (see
below)? How to save the file to GAE using a Blob column type? Is there
a special method that need to be overrided in the controller?

public class Image extends SienaSupport {
@Id(Generator.AUTO_INCREMENT)
public Long id;

@Column("title")
@Max(50)
@NotNull
public String title;

@Column("imageFile")
public Blob imageFile;
}

Thanks for your replies.

The automatic mapping doesn't exist for Blob yet (In fact, we are working on it at the current time in Siena)...

In your case, do you want the blob to be managed by the CrudSiena or do you manage it by yourself in your controller?

I think I misunderstand because my solution is really too basic :)

Can't you just do in your controller:
1) retrieve the byte[] corresponding to your file from the file
2) Blob imgBlob = new Blog(myimgbytes);
3) Image img = new Image();
img.imgBlob = imgBlob
...

img.insert();

Are you speaking about the CRUD controller or one of the controllers you coded by yourself for your app?
Do you want to enhance the CRUD controller with blob management?

Yes, I would like to enhance my CRUD controller so that it can save the file into the database. But I do not know the method to override. 

Thanks

I'm going to think a bit about the easiest way to do that...
Wait a second :)

Read my last mail about crudsiena module v1.4.
I did a quick workaround so that CrudSiena manages GAE Blob with Play.
