def cache_key
  # Ensure the cache key changes when the state changes. There are
  # cases during processing where the state is updated multiple
  # times in a single second. Since `cache_key` relies on
  # `updated_at`, which only is acurate to the second, we need to
  # prevent caching outdated information.
  "#{super}-#{state}"
end

#can_upload? ⇒ Boolean

#publish! ⇒ Object

Gets called to trigger the ‘file_uploaded` event in the upload state machine of UploadableFile. Files that are not uploaded through the editor (and therefore not using the upload state machine of UploadableFile) can overwrite this method to trigger whatever the file does (i.e. processing/transcoding), depending on the including class’ processing state machine.

# File 'app/models/concerns/pageflow/reusable_file.rb', line 134

def publish!
  raise 'Not implemented!'
end

#ready? ⇒ Boolean

Overwritten with the conditions that need to be fulfilled in order to (re)use the file.

Returns:

  • (Boolean)

end

#retry! ⇒ Object

If the conditions in retryable? are met then this method specifies what should happen when a retry is requested, depending on the including class’ processing state machine.

# File 'app/models/concerns/pageflow/reusable_file.rb', line 125

def retry!
  raise 'Not implemented!'
end

#retryable? ⇒ Boolean

Overwritten with the conditions that need to be fulfilled in order to ‘retry` whatever the file does (i.e. processing/transcoding).

Returns:

  • (Boolean)
