Examples and setup for the file_field Field Partial

Active Storage

file_field is designed to be used with Active Storage. You will need to confgure Active Storage for your application before using this field partial. You can find instructions for doing so in the Rails Guides.

In addition, Bullet Train has integrated the direct-uploads feature of Active Storage. For this to work, you need to have CORS configured for your storage endpoint. You can find instructions for doing so in the Rails Guides.

Example

The following steps illustrate how to add a document file attachment to a Post model.

Add the following to app/models/post.rb:

has_one_attached :document

Note, no database migration is required as ActiveStorage uses its own tables to store the attachments.

Run the following command to generate the scaffolding for the document field on the Post model:

./bin/super-scaffold crud-field Post document:file_field

Multiple Attachment Example

The following steps illustrate how to add multiple document file attachments to a Post model.

Add the following to app/models/post.rb:

has_many_attached :documents

Note, no database migration is required as ActiveStorage uses its own tables to store the attachments.

Run the following command to generate the scaffolding for the documents field on the Post model:

./bin/super-scaffold crud-field Post documents:file_field{multiple}

Generating a Model & Super Scaffold Example

If you’re starting fresh, and don’t have an existing model you can do something like this:

bin/super-scaffold crud Project Team name:text_field specification:file_field documents:file_field{multiple}
