How do I express this in my entities?

[niklassaers]

Hi guys,
I'm starting a new app and of course I want to use Roo for it. So just two quick questions for my entities:

How do I express a dictionary? In my case, I want a translatable text, so I've done this:

entity --class ~.data.entities.WrittenLanguage
field string --fieldName name

entity --class ~.data.entities.TranslateableText
field other --type java.util.HashMap<WrittenLanguage, String> --fieldName text

This is wrong, but how should I express a dictionary correctly?



The second question is that I want to have a set of permissions, so I define the following:

enum type --class ~.data.enums.Permission
enum constant --name UPDATE_ELEMENT
enum constant --name DELETE_ELEMENT
enum constant --name CREATE_ELEMENT
enum constant --name ADD_USER
enum constant --name BAN_USER

entity --class ~.data.entities.Person --extends Super
field string --fieldName username
field string --fieldName password
field string --fieldName email
field string --fieldName name
field set --fieldName permissions --element ~.data.enums.Permission

Roo is shocked that I even dare think this and quickly says: "The field set command is only applicable to JPA @Entity elements" I disagree, there are ways of expressing this, such as AND'ing the enums together and expressing it as an Integer or something. What is the correct way of doing this with Roo?

Cheers

The "field" commands don't accept parameterised maps. You'll need to edit the .java file by hand to add the map.

Re the enum question, you create them with "enum type". Then to add the field to your entity you need to use the "field enum" command. See the clinic.roo sample for an example.

Thanks a lot, Ben, I'll be sure to edit my map. I was just under the impression that I should use Roo to set up that type so that I could easily regenerate the entity setup afterwards, but I don't have much of a reason to regenerate, so this is fine. :-)

With regards to the Enum, "field enum" gives me a single enum, right? What I would like is a set of enums so that a user can have multiple non-overlapping permissions.
