Administrate::Field::ActiveStorage

rails

Things To Know:

  • to preview pdf files you need to install mupdf or Poppler.
  • to preview video files you need to install ffmpeg.

How To Use:

Add administrate-field-active_storage to your Gemfile:

gem 'administrate-field-active_storage'

Install:

$ bundle install

has_one_attached:

assuming your modelname is Model and field name is attachment

class ModelDashboard < Administrate::BaseDashboard
  ATTRIBUTE_TYPES = {
    attachment: Field::ActiveStorage,
  }
# ...

Then add :attachment to FORM_ATTRIBUTES and SHOW_PAGE_ATTRIBUTES. currently adding :attachment COLLECTION_ATTRIBUTES will work but will probably look too big.

has_many_attached:

assuming your modelname is Model and field name is attachments the processs is identical the only issue is that the form field isn't being permitted, in order to permit it we apply the following method to the dashboard:

class ModelDashboard < Administrate::BaseDashboard
  ATTRIBUTE_TYPES = {
    attachments: Field::ActiveStorage,
  }

  # ...
  FORM_ATTRIBUTES = {
    #...
    :attachments
  }

  # permitted for has_many_attached
  def permitted_attributes
    super + [:attachments => []]
  end

i know it is not ideal, if you have a workaround please submit a PR

url_only

only the following needs to change in order for the field to be url_only

class ModelDashboard < Administrate::BaseDashboard
  ATTRIBUTE_TYPES = {
    attachments: Field::ActiveStorage.with_options({url_only: true}),
    # ...
  }
  # ...
end

Things To Do:

  • upload single file
  • adding image support through url_for to support 3rd party cloud storage
  • use html 5 video element for video files
  • use html audio element for audio files
  • download link to other files
  • preview videos
  • preview pdfs
  • upload multiple files
  • find a way to delete attachments
  • preview office files as pictures
