Grails bindData exclude by annotation

I want to exclude domain field from data binding Is it possible to mark class field by an annotation?

For example domain:

class Article {
  String text
  .....
  Author author
}

in code I have to write bindData(article, params, [exclude: ['author']]) for cheating prevention

But much easier simple to annotate Author author. But I didn't find how.

Solution

  • Since Grails 2.1.0 you can use the bindable constraint to indicate that a property should not be automatically assigned during data binding.

    class Article {
    String text
    ...
    Author author

    static constraints = {
        author bindable: false
    }
}

    Now calling bindData(article, params) will automatically exclude the article's author property.
