ruby on rails - Paperclip not deleting attachments after model is destroyed -


I have a Rail 4 app and when I upgrade from Paperclip 3.5.2 to a newer version, my attachment There are no files removed from the file system after the related model is destroyed. I can not see anything in the documentation?

Here is my model code: 

  is_act_size: artwork, styles = & gt; {: Big => ["1400x1400 #" ,: jpg] ,: Cover => ["600x600 #" ,: jpg] ,: Medium = & gt; "170x170 #",: thumb = & gt; "50x50 #"},: convert_options = & gt; {: All = & gt; "-Quality 80colorspace RGB"}

Anything looks wrong?

I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
