SyntaxError in FilesController#new

[AnirudhaAgashe]

I am getting

syntax error, unexpected keyword_end, expecting end-of-input

for line

if current_user.can_read @folder || current_user.can_write @folder

I was able to get it to work by changing it to

if current_user.can_read(@folder) || current_user.can_write(@folder)
