Class: Glib::JsonUi::ViewBuilder::Fields::Upload

Inherits:
AbstractField show all
Includes:
FileUploadErrorHandler, Upload
Defined in:
app/helpers/glib/json_ui/view_builder/fields.rb

Overview

File upload field with direct-upload support and a progress list of already-attached files.

When re-editing a record, the field pre-populates multiProgressView.files from the model's attachments. Apps that disable ActiveStorage's default routes (config.active_storage.draw_routes = false) must define a glib_attachment_url_for(attachment) view helper returning their own authorized file URL -- see AbstractField#existing_attachment_url.
