# Examples and setup for the `file_field` Field Partial ## Active Storage `file_field` is designed to be used with [Active Storage](https://edgeguides.rubyonrails.org/active_storage_overview.html). 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](https://edgeguides.rubyonrails.org/active_storage_overview.html#setup). 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](https://edgeguides.rubyonrails.org/active_storage_overview.html#cross-origin-resource-sharing-cors-configuration). ## Example Add a 'document' file as an attachment to a `Post` model: Add the following to `app/models/post.rb`: ```ruby 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: ```bash ./bin/super-scaffold crud-field Post document:file_field ```
