ruby on rails 4 - Paper Clip is not saving thumbnails -


i have following code in model:

   has_attached_file :avatar,             path: ':class/:attachment/:id/:style/:basename.:extension',             :styles=> { :original => "500x500",                       :small => "200x200"                    }, default_url: "icons/user.png"

i have installed imagemagick. 

which convert /usr/bin/convert

in development.rb

 paperclip.options[:command_path] = %w(/usr/local/bin/ /usr/bin/)

i have tried following:

   paperclip.options[:command_path] = "/usr/bin/"

but when try upload picture saves original file. message log is:

[paperclip] saving user_profiles/avatars/53/original/2015-06-08-153213.jpg

what i'm missing?

in model can add below code. don't need worry size specified in code, can change size need.

  has_attached_file :avatar, styles: { medium: '200x200>', thumb: '80x80>' }, default_url: "/icons/user.png"   validates_attachment_content_type :avatar, content_type: /\aimage\/.*\z/

in case convert path /usr/bin/convert. default path. don't need specify in development.rb file. please remove , give try.

also make sure have permitted params in controller.

sample code

# in controller file private def user_params   params.require(:user).permit(:email, :avatar) end

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
