Displaying a Carrierwave filename in the view

I am trying to display the filename of a Carrierwave attachment in a Rails erb template. The following does not work:

<%= @page.form.filename %>

This seems in line with the documentation. Is some additional step needed?

My page model looks like this:

class Page < ActiveRecord::Base

  mount_uploader :form, FormUploader

end

The form uploader looks like this:

class FormUploader < CarrierWave::Uploader::Base

  storage :file

  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

  def extension_white_list
    %w(pdf)
  end

end

Undefined Method Scale In CarrierWave

I'm trying to use this code in my uploader

  version :thumb do
    process :scale => [50, 50]
  end

and I get an error saying

undefined method `scale' for #<#<Class:0x235b680>:0x0fb4c8>

I'm using Carrierwave with MiniMagick. How can I fix this error?

Reprocessing images in Carrierwave

Let's say my model has an image with :thumb and the client wants :tiny and :nano thumbnails.

How do I reprocess all the existing images using a rake task?

I've found a rask that I thought would do it https://gist.github.com/777788 but it's giving me errors.

Undefined method `image_will_change!' for CarrierWave on Heroku

I have a simple model that mounts a Carrierwave uploader. Everything works fine in development, but I get an undefined method "image_will_change!" error on heroku.

class Receipt < ActiveRecord::Base
  mount_uploader :image, ImageUploader
end

class ImageUploader < CarrierWave::Uploader::Base
  storage :fog
  def store_dir
    "receipts/saved"
  end
end

I have the cache_dir set appropriately as well according to the Carrierwave Wiki.

receipt.image = File.open "public/images/test.jpg" #works fine in development, fails in heroku

Carrierwave - Resizing images to fixed width

I'm using RMagick and want my images to be resized to a fixed width of 100px, and scale the height proportionally. For example, if a user were to upload a 300x900px, I would like it to be scaled to 100x300px.

validate size of upload using Carrierwave

In our latest application we need to process some uploads, I've worked with paperclip before and everything just works! but we're giving carrierwave a try, it looks promising but, I can't find how to validate the size of an attachment, it seems like the documentation doesn't have any information about it, should we add it manually to the model via a custom validator?

Thanks in advance!

Rails 4 multiple image or file upload using carrierwave

carrierwave - rails 3.1- undefined method: image_will_change

I get an error that look like this:

undefined method `post_image_will_change!' for #<Post:0xf4e9184>
app/controllers/posts_controller.rb:43:in `new'
app/controllers/posts_controller.rb:43:in `create'

I've included this in my "post" model:

 attr_accessible :title, :name, :content, :post_image
 mount_uploader :post_image, PostImageUploader

and in _form.html.erb I've added:

 :html =>  { :multipart => true }

I looked CarrierWave Error but that doesn't help me.

Any clues of what generates that error? I've migrated the database and so forth (followed the railscasts guide on carrierwave exactly..)

Rails 3 test fixtures with carrierwave?

I'm working on upgrading from attachment_fu to carrierwave, since attachment_fu is broken in rails 3.

None of the tests are able to run, because we have invalid fixtures that were using the syntax from attachment_fu for attachment files.

For example, we have a Post model that has one PostAttachment. Here's what the data in the PostAttachment fixture looks like:

a_image:
  post_id: 1
  attachment_file: <%= Rails.root>/test/files/test.png

And this is the error I'm getting:

ActiveRecord::StatementInvalid: PGError: ERROR:  column "attachment_file" of relation "post_attachments" does not exist
LINE 1: INSERT INTO "post_attachments" ("post_id", "attachment_file"...

attachment_file would have been picked up by attachment_fu, and it would have taken care of all the processing to create the attachment_fu attachment for the model.

Is there a way to have image attachments in the fixtures, but with using CarrierWave instead?

rmagick leads to server shutdown

everyone! I was following Railscasts episode #253, using CarrierWave to do image upload.

Everything was fine to display the original image, even though the image looked quite big in the browser.

I strictly followed Ryan Bates' instructions. But, when I tried to resize the image using rmagick and press upload button, I always got server shutdown. I am using rmagick 2.13.1 And I followed this blog's instruction to install homebrew, and imagemagick on my mac.

The error message is shown below.

CarrierWave and resize to a specific width
