I using a heimdallr for my models, and in the views use a destroyable? method, but I use destoy scope only for owners or admins, and when user not login destroyable? method raise Runtime error The :delete scope does not exist

How to fix this?

Answer 1

Have you tried creating a :delete scope or method on the model and setting it to something that doesn’t return records?

It looks like this code is where it is failing:

https://github.com/roundlake/heimdallr/blob/master/lib/heimdallr/proxy/record.rb

def destroyable?
  scope = @restrictions.request_scope(:delete)
  record_in_scope? scope
end

So if your scope returns no records, it should in theory work just fine.

scope :delete, where(YourModel.arel_table[:id].lt(0))
