Granting read permission on intermediate STI table prevents any records being returned about cancancan

[owst]

Similarly to this comment #663 (comment) adding this before the test "fixes" the test:

CanCan::RulesCompressor.class_eval do
  def compress(array)
    # Don't compress...
    array
  end
end

I just wasted a few hours fighting with this error today 😔

    # Don't compress...

  end

This solution didn't work for me, I figured out the problem is the StiNormalizer introduced in #649 so a possible solution could be to go back to the 3.1.0 version.

At the end I prefered to overwrite the StiDetector class to that it stops adding the type = ... filter to the query only for the models I need

class StiDetector
  class << self
    alias_method :sti_class_original?, :sti_class?

    def sti_class?(subject)
      if subject == MyModel
        false
      else
        sti_class_original?(subject)
      end
    end
  end
end

I am getting the same issue for some reason cancancan 3.5.0 is adding an extra where condition type="'.

This patch worked fine: #663 (comment)
But it breaks another part of my app. :(

System configuration

• Rails version: 6.1.7
