title: How do I use carrierwave in Rails without a model?
body: <p>I simply want a form where a user chooses an image and it gets submitted to AWS S3..</p>
  
  <p>This is the page where my form is</p>
  
  <pre><code>&lt;%= form_tag('process', multipart: true) do %&gt;
    &lt;p&gt;
      &lt;label&gt;My Image&lt;/label&gt;
      &lt;%= file_field :AssetImage %&gt;
      &lt;%= submit_tag "Send!" %&gt;
    &lt;/p&gt;
  &lt;% end %&gt;
  </code></pre>
  
  <p>I'm getting the error wrong number of arguments (1 for 2) for file_field..</p>
  
  <pre><code>CarrierWave.configure do |config|
    config.fog_credentials = {
      :provider               =&gt; 'AWS',                        # required
      :aws_access_key_id      =&gt; 'asdf',                        # required
      :aws_secret_access_key  =&gt; 'asdf',                            # required
      :host                   =&gt; 'https://s3.amazonaws.com',             # optional, defaults to nil
    }
    config.fog_directory  = 'AssetImage'                     # required
    config.fog_public     = true                                   # optional, defaults to     true
    config.fog_attributes = {'Cache-Control'=&gt;'max-age=315576000'}  # optional, defaults to {}
  end
  </code></pre>
  
  <p>that's my config and in the uploader i have storage :fog set. I don't understand!! I don't want it associated with anything.. I just want it to upload</p>
