Hey there,
I am trying to write a simple function to clean a filename string and update the object. When I save a test string it works, but when I try to save the string variable I've created, nothing happens. But when I return the string, the output seems to be correct! What am I missing?
def clean_filename
clean_name = filename
clean_name.gsub! /^.*(\\|\/)/, ''
clean_name.gsub! /[^A-Za-z0-9\.\-]/, '_'
clean_name.gsub!(/\_+/, ' ')
#update_attribute(:filename, "test") #<-- correctly sets filename to test
#update_attribute(:filename, clean_name) #<-- no effect????? WTF
#return clean_name <-- seems to returns the correct string
end
Thank you very much.
