I found the problem. I was defining a new method content_type in the class Tempfile.
*class Tempfile def content_type mime_type = IO.popen("file --brief --mime #{path}").gets unless path.blank? mime_type end end* How can I make this without breaking generators? I've already tried the following one (exactly how it is on the tempfile.rb), but it didn't work: *class Tempfile < DelegateClass(File) ... end* Should I enclose it by *module SomeModuleName ... end* ? Thanks in advance.
