Bulk delete attachements

redmine_attachment_bulk_delete

Single and bulk deletion of attachments in Redmine 6.1.x – in two places:

1. Issue view, “Attachments” section – checkbox per attachment + button “Delete selected” (a single-item trash icon was already there).
2. Attachment edit page /attachments/<type>/<id>/edit – previously only renaming; now also checkboxes, “Delete selected” and a trash icon per row.

Works generically for wiki pages, forums, documents, projects, versions and news as well (anywhere Redmine offers attachments and the “Edit” link).

How it works (short version)

• No core override. The plugin only adds its own controller (AttachmentBulkController) + one route (POST /attachments/bulk_destroy) and enhances the existing views via JavaScript (view_layouts_base_html_head hook). This keeps it upgrade-safe.
• Permissions are checked server-side as the final authority:
  • Issues via the regular Redmine path (safe_attributes = {'deleted_attachment_ids' => ...} + save), i.e. identical to the normal edit form. Requires edit_issues (or edit_own_issues as author).
  • Other containers via attachment.deletable?.
• History stays correct: one journal entry per deletion, with one “File deleted” detail per attachment.
• The JavaScript only shows the buttons where the “Edit” link is present (= permission exists) – fail-closed.

Installation

cd ./plugins
git clone https://github.com/admnwrk/redmine_attachment_bulk_delete.git

In a Docker Compose setup: place the folder in the plugins volume and restart the hitredmine container. There is no migration. Assets are automatically copied by Redmine on startup to public/plugin_assets/redmine_attachment_bulk_delete/.

Configuration / Customization

• UI texts (German) are centralized in the T object at the top of assets/javascripts/attachment_bulk_delete.js.
• Allowed container types: constant ALLOWED_CONTAINERS in the controller.
