没有名称的载波上传文件

Question

It's me again. I try to upload some yaml files with carrierwave. Everything works fine till now.

So, as you know for carrierwave the forms looks like the follow:

<%= form_for @resume, html: { multipart: true } do |f| %>
      <%= f.label :name %><br>
      <%= f.text_field :name, :required => true %>
      <%= f.label :attachment %><br>
      <%= f.file_field :attachment, :required => true %>
      <br><br>
      <%= f.submit "Save", class: "btn btn-primary" %>
  <% end %>

What i want to do now is to remove the "name" field. I don't need it. So i thought its quite easy, just remove the "name" part of the form. But then I got an error while upload:

Name can't be blank

So I tried now nearly everything... I had set the required => false same result. I went to Github and tooked a look at their how-to... there are methods to overwrite the name, but nobody cares about upload a file without a name. May somebody can tell me how i can upload a file without this name field?

Thanks!

Edit:

My resume.rb model:

class Resume < ActiveRecord::Base
  mount_uploader :attachment, AttachmentUploader # Tells rails to use this uploader for this model.


end

My AttachmentUploader:

class AttachmentUploader < CarrierWave::Uploader::Base
  storage :file

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

  def extension_white_list
    %w(yml)
  end

  def filename
    "something.jpg" if original_filename # This is the part where i'm trying around right now.
  end

end

Try to remove column name on table resumes and others related, maybe on views, controller ( strong params ), migration file...

Then re-run drop, migrate database
