Re: [Wonder-disc] Migrations

[David H. <pro...@ma...>]

Hi Josh,

Have you had the chance to look at the package overview for  
ERXMigrations? This helped me a lot.

http://webobjects.mdimension.com/wonder/api/er/extensions/migration/ 
package-summary.html

You're doing your migration the old way (with the sql file). You can  
now use the java api to do this (at least for MySQL, FrontBase and  
PostgreSQL) and you can have EntityModeler generate your first  
migration 0 class.

Take a look at er.attachment.migrations to see an example how they  
are used.

Have you declared your database variables in your properties file? I  
think that Migrations will need to create a database update table in  
your database.
i.e.
dbConnectURLGLOBAL=jdbc:FrontBase://localhost/databaseName
dbConnectUserGLOBAL=bug
dbEOPrototypesEntityGLOBAL=EOJDBCFrontBasePrototypes

So long as your model is in the project or referenced from the  
project I don't believe you need to put in the model name or the  
class prefix in your properties.
