A plugin to upload and preview Carrierwave attachments in Administrate.

Add it to your Gemfile:

gem 'administrate-field-carrierwave', '~> 0.2.0'

Run:

$ bundle install

Add to your FooDashboard:

ATTRIBUTE_TYPES = {
  bar: Field::Carrierwave.with_options(
    image: :standard,
    multiple: true,
    image_on_index: true
  )
}.freeze

To handle multiple asset uploads, the attribute must point to an empty array in a hash:

# If multiple: true
def permitted_attributes
  super - [:bar] + [{ bar: [] }]
end

• image (default: nil): a version that will be displayed in an <img> element.
• image_on_index (default: false): whether or not to show the image itself on the index list view. The default behavior (when false) is to display a "View" link that opens the image in a new tab/window when clicked.
• multiple (default: false): allows uploading of multiple files. ATTENTION 🚨: requires CarrierWave’s master branch. Uploaded files will replace the current ones – if present – and not add to them.
