Based on the exploration findings, I need to design a fix for the document viewing issue after import.

Problem Summary:

When UPLOAD_DOCUMENT_WRITE feature switch is enabled: 1. Documents are uploaded successfully via /doctor_app/v2/documents (POST) 2. User immediately tries to view the document 3. Viewing fails because React Query cache is stale 4. After 5 minutes (cache expiry) or logout, viewing works

Root Cause:

The useDocumentsCreate() mutation in /engines/documents/app/assets/javascripts/queries/documents/doctor_app/documents.ts (lines 443-551) has NO onSuccess handler to invalidate cache.

In contrast, useDocumentsUpdate() (lines 415-427 in same file) properly invalidates: - buildDocumentsShowQueryKey(props.documentId) - Patient and appointment document indices

Cache Configuration:

• DOCUMENT_STALE_TIME = 5 * 60 * 1000 (5 minutes)
• DOCUMENT_CACHE_TIME = 5 * 60 * 1000 (5 minutes)
• Query key: buildDecryptedDocumentQueryKey(documentId) → ['doctor_app', 'decrypted_documents_url', documentId]

Design Requirements:

1. Add proper cache invalidation to useDocumentsCreate() mutation
2. Invalidate the decryptedDocuments query for the newly created document
3. Invalidate related document list queries (patient, appointment, unclassified)
4. Follow the same pattern as useDocumentsUpdate() for consistency
5. Preserve the existing 5-minute cache times (don't remove caching completely)
6. Ensure it works with both V1 and V2 API endpoints

Files to Modify:

• /engines/documents/app/assets/javascripts/queries/documents/doctor_app/documents.ts (add onSuccess to useDocumentsCreate)
• Potentially /engines/documents/app/assets/javascripts/queries/documents/doctor_app/decryptedDocuments.ts (if we need helper functions)

Please design: 1. What queries should be invalidated after document creation 2. How to structure the onSuccess handler 3. Whether we need any helper functions 4. Any edge cases to consider

I'll design a comprehensive solution to fix the document viewing issue after import. Let me explore the relevant code to understand the complete cache invalidation pattern.

Perfect! Now I have a complete understanding of the issue and the solution. Let me create a comprehensive implementation plan.

Implementation Plan: Fix Document Viewing After Import

Problem Analysis

Root Cause: The useDocumentsCreate() mutation successfully uploads documents via the V2 endpoint (/doctor_app/v2/documents) but lacks an onSuccess handler to invalidate React Query caches. This causes:

1. Document show cache (decryptedDocuments) to remain stale - the newly created documentId doesn't exist in cache
2. Document list caches (patient, appointment, unclassified) to show outdated data without the new document
3. Users must wait 5 minutes (cache expiry time) or logout before viewing works

Why Update Works: useDocumentsUpdate() (lines 415-427) already has proper cache invalidation that serves as our reference implementation.

Solution Design

Architecture: Add an onSuccess handler to useDocumentsCreate() that mirrors the pattern in useDocumentsUpdate().

Queries to Invalidate:

1. Document Show Query - buildDocumentsShowQueryKey(documentId) - Key: ['documents', 'doctor_app', 'documents', 'show', documentId] - Purpose: Ensures viewing the newly created document works immediately

2. Decrypted Document Query - buildDecryptedDocumentQueryKey(documentId)
   - Key: ['doctor_app', 'decrypted_documents_url', documentId] - Purpose: Ensures encrypted documents can be decrypted and viewed

3. Patient Documents Index - buildDocumentsIndexQueryKey({ patient_id }) - Key: ['documents', 'doctor_app', 'documents', 'index', { patient_id, ... }] - Purpose: Document lists in patient context show new document - Also invalidate: useInvalidatePatientDocuments(patientId)

4. Appointment Documents Index - buildDocumentsIndexQueryKey({ appointment_id }) - Purpose: Document lists in appointment context show new document - Also invalidate: useInvalidateAppointmentDocuments()

5. Global Documents Index - buildDocumentsIndexQueryKey() (no params) - Purpose: Unclassified documents view shows new document

Data Flow Analysis:

From useDocumentEdit/helpers.ts (lines 321-351), the FormData includes: - document[patient_id] - always present (from attributes.patient.id or document.patient_id) - patient_id - present for unattached documents (line 350-351) - appointment_id - present when document.appointment_id exists (line 346)

The mutation response returns:

{ document: { id: string } }

Implementation Strategy:

// In useDocumentsCreate(), add onSuccess handler after mutationFn
export const useDocumentsCreate = () => {
  const buildEncryptedFormData = useEncryptedDocumentFormDataBuilder()
  const queryClient = useQueryClient()
  const invalidatePatientDocuments = useInvalidatePatientDocuments()
  const invalidateAppointmentDocuments = useInvalidateAppointmentDocuments()

  return useMutation<DocumentsCreateData, HttpError, DocumentsCreateVariables>({
    mutationFn: async (variables) => {
      // ... existing mutationFn code (lines 448-548) ...
    },
    onSuccess: (data, variables) => {
      const documentId = data.document.id

      // 1. Invalidate the show query for the new document
      queryClient.invalidateQueries({ queryKey: buildDocumentsShowQueryKey(documentId) })

      // 2. Invalidate the decrypted document query
      queryClient.invalidateQueries({ queryKey: buildDecryptedDocumentQueryKey(documentId) })

      // 3. Extract patientId from variables
      let patientId: string | undefined
      if (variables.encryptionEnabled) {
        patientId = variables.patient_id
      } else {
        // For non-encrypted variables (FormData), extract patient_id
        const body = variables.body as FormData | DocumentFormData
        if (body instanceof FormData) {
          patientId = body.get('document[patient_id]') as string || body.get('patient_id') as string
        } else {
          // DocumentFormData structure
          patientId = body.patient_id?.toString() || body.document?.patient_id
        }
      }

      // 4. Invalidate appointment documents (all appointments, since we don't have specific ID)
      invalidateAppointmentDocuments()

      // 5. Invalidate patient documents
      if (patientId) {
        queryClient.invalidateQueries({ queryKey: buildDocumentsIndexQueryKey({ patient_id: patientId }) })
        invalidatePatientDocuments(patientId)
      } else {
        // Invalidate all patient documents if no specific patientId
        invalidatePatientDocuments()
      }

      // 6. Invalidate global documents index (for unclassified documents)
      queryClient.invalidateQueries({ queryKey: buildDocumentsIndexQueryKey() })
    },
  })
}

Edge Cases Handled:

1. Encrypted vs Non-Encrypted Documents: - Encrypted: variables.encryptionEnabled === true, patient_id in variables.patient_id - Non-encrypted: variables.encryptionEnabled === false, patient_id in variables.body (FormData or DocumentFormData)

2. FormData Structure: - Could be actual FormData object (from legacy code) - Could be typed DocumentFormData object - Patient ID could be in document[patient_id], patient_id, or body.document.patient_id

3. Missing Patient ID: - Invalidate all patient/appointment documents if patientId cannot be extracted - Ensures new document appears even if context is unclear

4. V1 vs V2 API Compatibility: - Both endpoints return same structure: { document: { id } } - Solution works for both via buildDocumentEndpoint() logic (line 509)

5. Decrypted Document Cache: - Must invalidate BOTH show query AND decrypted query - Show query: encrypted document metadata - Decrypted query: decrypted blob URL for viewing

Performance Considerations:

1. Selective Invalidation: Only invalidate queries that actually exist in cache (React Query handles this automatically)
2. No Refetch Cascade: Using invalidateQueries instead of refetchQueries - only refetches active queries
3. Minimal Network: Documents show query only refetches when user attempts to view
4. Index Updates: Document lists refetch when user navigates to those views

Testing Strategy:

1. Manual Test Flow: - Enable UPLOAD_DOCUMENT_WRITE feature switch - Import document via secure messaging - Immediately click to view document - Verify: Document displays without 404 error - Verify: Document appears in patient document list - Verify: Document appears in appointment document list (if attached)

2. Cache Inspection: - Use React Query DevTools to verify queries are invalidated - Check that decrypted_documents_url query exists for new documentId - Check that document index queries are marked as stale

3. Regression Testing: - Verify document update still works (uses existing useDocumentsUpdate) - Verify V1 API still works (when feature switch disabled) - Verify encrypted documents display correctly - Verify non-encrypted documents display correctly

Implementation Checklist:

1. Import required helpers at top of file: - buildDecryptedDocumentQueryKey from ./decryptedDocuments - Already have: useInvalidatePatientDocuments, useInvalidateAppointmentDocuments, buildDocumentsIndexQueryKey, buildDocumentsShowQueryKey

2. Initialize hooks in useDocumentsCreate: - const queryClient = useQueryClient() - const invalidatePatientDocuments = useInvalidatePatientDocuments() - const invalidateAppointmentDocuments = useInvalidateAppointmentDocuments()

3. Add onSuccess handler after mutationFn (around line 549)

4. Extract patientId logic with proper type guards for FormData vs DocumentFormData

5. Call invalidation functions in correct order
