Description

Allows coordinators to attach supporting documents to activity records — including invitations, Facebook event screenshots, flyers, and other evidence materials. NHF specifically requires this for Bufdir verification, where inspectors may request proof that a registered activity actually took place. Attachments are linked at the activity level and can be uploaded from the device camera roll or file system. The feature must support common formats (PDF, JPEG, PNG) and store files securely in Supabase Storage with appropriate access controls so only coordinators and admins within the same organisation can retrieve them.

Analysis

Business Value

Enables NHF to meet Bufdir's evidence requirements without maintaining a separate paper archive. Reduces audit risk and administrative burden when grant inspections occur.

Implementation Notes

Use Supabase Storage with bucket-level RLS tied to org_id. Limit file size to 10 MB per attachment, max 5 attachments per activity. Generate signed URLs for download. Display thumbnails in activity detail view. Include attachment count and download links in Bufdir export.

As a As a Coordinator

I want to attach multiple documents (e.g., an invitation flyer, a participant list, and a screenshot) to a single activity in one session

So that I can provide all evidence at once without having to revisit the activity multiple times

Acceptance Criteria
  • Given the attachment picker is open, when I select multiple files from my photo library, then all selected files appear as thumbnails in a pending upload queue
  • Given the pending upload queue has 3 files, when I tap 'Upload', then all three files upload in parallel and I see individual progress indicators for each
  • Given all uploads have succeeded, when the upload session ends, then all thumbnails appear in the activity's attachment thumbnail grid

Attach Documents Offline and Sync When Connectivity Is Restored
medium 8 pts

As a As a Coordinator

I want to queue document attachments locally when I have no internet connection and have them automatically uploaded when connectivity is restored

So that I can complete activity registration with attachments in remote or low-connectivity environments without losing my work

Acceptance Criteria
  • Given I am offline and attach a document to an activity, when I confirm the selection, then the file is stored locally and shown in the thumbnail grid with a 'Pending upload' indicator
  • Given there is a pending attachment queue, when the device regains internet connectivity, then all queued files are uploaded automatically in the background
  • Given background sync completes successfully, when all queued attachments are uploaded, then the 'Pending upload' indicators are replaced with normal thumbnails and a success notification is shown
