carrierwave thumb issue

Question

This question was asked, but no answer given...I'm having the same issue.

I'm using carrierwave for uploading files everything works great until i wanted to create thumbs

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

My avatar_uploader.rb file looks like this:

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 don't include (:thumb), I see the full images...but when I do include 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 can see that a tmp directory was created, but images not resized...I have imagemagick and rmagick installed...

Thank you

Answer 1

I think you might want to recreate versions since you might have create thumb size for some images after you uploaded some other files.

image.avatar.url(:thumb)

above syntax is fine

To recreate versions try running

image.avatar.recreate_versions!

on all avatars you might be missing.

Answer 2

Try one of these syntaxes:

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