Allow excluding fields from query instead of including them #629
Description
Please summarize your feature request
Add method to query builder to exclude fields from result. All fields not excluded are in result.
Describe the functionality you're seeking in more detail
If my model contains a blob, and I don't always want to load the blob to save load on the database, it's a lot less work to say "don't load the blob" than to say "for each field that isn't the blob, do load that field". Expecting the new method would be field(exclude:) and it would not be allowed to mix exclude with include.
Have you considered any alternatives?
Listing every field except the one I want to exclude.
