Media problem

Question

This question was asked, but there was no answer ... I have the same problem.

I use a carrier to download files, everything works fine until I wanted to create a thumbs up.

images are saved in tmp direct, but saved in the same size ...

The file of my avatar_uploader.rb is as follows:

class AvatarUploader < CarrierWave::Uploader::Base include CarrierWave::RMagick storage :file def store_dir "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}" end version :thumb do process :resize_to_limit => [200, 200] end 

My view has the following:

 <% for image in @posts %> <%= image_tag image.avatar_url(:thumb) if image.avatar? %> <%= image.title %> <% end %> 

When I do not turn on (: the thumb), I see full images ... but when I turn on (: the thumb), I get the following error:

 Version thumb doesn't exist! 

below is my model setup

 class Post < ActiveRecord::Base attr_accessible :comments, :frame, :title, :twitter, :avatar belongs_to :user mount_uploader :avatar, AvatarUploader end 

I see that the tmp directory was created, but the images did not change ... I have imagemagick and rmagick ...

thanks

Answer 1

I think you might want to recreate the versions, as you can create a thumb size for some images after you have downloaded some other files.

 image.avatar.url(:thumb) 

the syntax above is fine

To recreate the versions, try running

 image.avatar.recreate_versions! 

on all avatars that may be missing.

Answer 2

Try one of these syntaxes:

 image.avatar.thumb.url # or image.avatar.url(:thumb) 

Answer 3

I suggest using

 include CarrierWave::MiniMagick 

instead

 include CarrierWave::RMagick 

Because it may happen that you do not have all the dependent RMagick libraries. The Thumb version is created using RMagick or MiniMagick. Problem with your RMagick.

Have you tried Dragon Pearls? I know that I do not solve your problem. But after using it a couple of times, I think it's better than a carrier wave when it comes to images. Dragonfly Gem does not create many images, just resizes one image to the size you specify, compared to the carrier, which creates a lot of thumbs.
