whereIsNotNull is not computing relation field name

[alez007]

Hello,

First of all, thank you for this library ;)

Just a quick one that fortunately has a fix but can be added to future updates:

new RushSearch().startGroup().whereIsNotNull("user").and().whereEqual("user", user).endGroup().orderDesc("created").find(AssetModel.class);

is "user" is a relation and it happens to return null, let's say we saved AssetModel with a null user at some point, then whereIsNotNull is only searching for a table primitive named "user", the where statement looks like this:

WHERE (rush_uk_co_vicast_communityapp_model_AssetModel_rush_uk_co_vicast_communityapp_model_UserModel_user.child IS NOT NULL AND user='V8g95') and normally we should replace "user" with "rush_uk_co_vicast_communityapp_model_AssetModel_rush_uk_co_vicast_communityapp_model_UserModel_user.child" for the full query to work.

A fast fix would be to calculate the "user" relation field name in advance like this:

Map annotationCache = RushCore.getInstance().getAnnotationCache(); String userFieldName = ReflectionUtils.joinTableNameForClass(((AnnotationCache)annotationCache.get(AssetModel.class)).getTableName(), ((AnnotationCache)annotationCache.get(UserModel.class)).getTableName(), "user") + ".child";

and then insert it into the query replacing "user" to userFieldName variable.

Thank you,
Alex
