CRUD with entity relationship

[sachsoft]

Thanks for providing seam-gen and the facility to create CRUD .
Its really fast and simple. Also this feature is great for ‘Master Tables’ for almost all projects.

I would like to know if the CRUD entities support relationhip..Let me explain it in more details

I have got 2 entities
Book (id,name,publisherId)
Publisher(publisherId,name)

Relation – One book can have one publisher. A publisher can publish many books.

When I created the tables in MySQL and also created Model Classes for these  Entities  with  a  @ManyToOne relation for publisherId in the Books Model class

I used ‘Generate  Seam Entities’ with ’Use existing entities’ as Genetation mode.
This gave me all the screens  .But the Add Books screen had a separate tab to select the Publisher.

Instead I would prefer to have a list of Publishers in a select/dropdown box .. is there any simple trick to achieve this.

No.

Seam-gen generates generic files for you. You have to manually change them for any of your own wishes.

There are some projects which try to go beyond seam-gen:

To get an idea of what seam-gen doesn't deal with, you can check jira issues.
