Annotation to avoid a property being filled in ContentValues

[dianaghele]

Is there any annotation or something to add to a property in order for it to be left out when building toContentValues?
I would need this for the Ids that are autoincremented primary keys.

Thanks!

Currently there isn't a way, but you can add and implement a second toValues() method that calls the abstract one and then removes the id or other columns.

@AutoValue public abstract class User {
  abstract String id();
  abstract String name();
  abstract String email();

  // you can choose whichever name you want for the method
  abstract ContentValues toCompleteContentValues();

  public ContentValues toContentValues() {
    return toCompleteContentValues().remove("id");
  }
}

Thanks for the info!

Do you plan to add something to resolve this?

You can use the new @ValuesAdapter annotation for custom types in 0.4.0-SNAPSHOT to ignore fields when creating ContentValues.

public final class IgnoreFieldAdapter {
  public static ContentValues ignoreField(String s) {
    return null;
  }
}

@AutoValue public abstract class User {
  @ValuesAdapter(IgnoreFieldAdapter.class) abstract String id();
  abstract String name();
  abstract String email();

  abstract ContentValues toValues();
}

I'm wondering since ValuesAdapter is no longer a thing, how is this supposed to work with a ColumnTypeAdapter?
