code type database value [message #758158] Tue, 22 November 2011 03:01 Go to next message

Hi,

I try to use the codeType in combination with a smart field. In the (legacy) database the values are already defined. So in the database I have to deal with integer values, double values, string values etc.

Can I map the code type to alternate database values, if yes how?

Regards Bertin

Hi,

Somehow I missed the wiki page about the codeType http://wiki.eclipse.org/Scout/Concepts/CodeType. It works now with the help of this documentation.

Although there is some error in the New Code Type dialog. I created a codeType with a generic type String. If I try to enter a string value in the Code ID field I always get an error "code it must be a number (long)."

As a workaround I filled in a number and Finish. In the generated code I changed the ID to string, altered the value to a string value and implemented getId() correctly and it works.

Regards Bertin

To my mind this is a bug, because there is no limitation on the type of the id of a Code and/or a CodeType.
As you point out you need to do the correction directly in Java (maybe with the property view, I am not sure what the status is there). You can open a Bug in Bugzilla.


I wanted to add that it is not necessary to add the codes in the CodeType if you load them from a Database (with execLoadCodes(..)). [see: section "Dynamic CodeType" of the CodeType page]


For your problem, you can also consider using a LookupCall (with a LookupService using a database) The main difference is that for a LookupCall (with a LookupService executing a query in a DB) the call is resolved each time and for a CodeType there is some caching (on the client and the server). Therefore CodeType is to be used for master data (that do not change much) and LookupCall for more volatile information.
