Compile error on missing @ManyToOne instead of ClassCastException at runtime

[Pear0]

I'm fairly new to Requery and I forgot @ManyToOne on my model class.

@Entity
abstract class AbstractFeedNotification {

    @Key
    @Generated
    int id;

    @Column(nullable = false)
    // @ManyToOne
    FeedSubscription feed;
   
   ...
}

It appears that Requery is converting it to a varchar when storing it in the database instead of an id reference, but this is not obvious and it doesn't cause an error until I try to select from the database.

database.select(FeedNotification.class)
                .where(FeedNotification.ID.eq(id))
                .get()
                .first();

Here's the exception thrown:

java.lang.ClassCastException: Cannot cast java.lang.String to com.example.FeedSubscription
                                                                       at java.lang.Class.cast(Class.java:2308)
                                                                       at io.requery.sql.GenericMapping.read(GenericMapping.java:287)
                                                                       at io.requery.sql.EntityReader.fromResult(EntityReader.java:564)
                                                                       at io.requery.sql.EntityResultReader.read(EntityResultReader.java:45)
                                                                       at io.requery.sql.ResultSetIterator.next(ResultSetIterator.java:101)

It would be nice if this caused a compile-time error as it seems like something that can be validated when the model implementations are generated.

My Requery versions:

compile 'io.requery:requery:1.1.0'
compile 'io.requery:requery-android:1.1.0'
apt 'io.requery:requery-processor:1.1.0'
compile 'io.requery:sqlite-android:3.15.1'

Thanks yes it make sense to make that an error, should be included in the next update
