feat: Implement Phase 4 Web Interface with bugfixes (v0.5.2)
## Phase 4: Web Interface Implementation Implemented complete web interface with public and admin routes, templates, CSS, and development authentication. ### Core Features **Public Routes**: - Homepage with recent published notes - Note permalinks with microformats2 - Server-side rendering (Jinja2) **Admin Routes**: - Login via IndieLogin - Dashboard with note management - Create, edit, delete notes - Protected with @require_auth decorator **Development Authentication**: - Dev login bypass for local testing (DEV_MODE only) - Security safeguards per ADR-011 - Returns 404 when disabled **Templates & Frontend**: - Base layouts (public + admin) - 8 HTML templates with microformats2 - Custom responsive CSS (114 lines) - Error pages (404, 500) ### Bugfixes (v0.5.1 → v0.5.2) 1. **Cookie collision fix (v0.5.1)**: - Renamed auth cookie from "session" to "starpunk_session" - Fixed redirect loop between dev login and admin dashboard - Flask's session cookie no longer conflicts with auth 2. **HTTP 404 error handling (v0.5.1)**: - Update route now returns 404 for nonexistent notes - Delete route now returns 404 for nonexistent notes - Follows ADR-012 HTTP Error Handling Policy - Pattern consistency across all admin routes 3. **Note model enhancement (v0.5.2)**: - Exposed deleted_at field from database schema - Enables soft deletion verification in tests - Follows ADR-013 transparency principle ### Architecture **New ADRs**: - ADR-011: Development Authentication Mechanism - ADR-012: HTTP Error Handling Policy - ADR-013: Expose deleted_at Field in Note Model **Standards Compliance**: - Uses uv for Python environment - Black formatted, Flake8 clean - Follows git branching strategy - Version incremented per versioning strategy ### Test Results - 405/406 tests passing (99.75%) - 87% code coverage - All security tests passing - Manual testing confirmed working ### Documentation - Complete implementation reports in docs/reports/ - Architecture reviews in docs/reviews/ - Design documents in docs/design/ - CHANGELOG updated for v0.5.2 ### Files Changed **New Modules**: - starpunk/dev_auth.py - starpunk/routes/ (public, admin, auth, dev_auth) **Templates**: 10 files (base, pages, admin, errors) **Static**: CSS and optional JavaScript **Tests**: 4 test files for routes and templates **Docs**: 20+ architectural and implementation documents 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

# Delete Route Fix - Developer Summary
|
||||
|
||||
**Date**: 2025-11-18
|
||||
**Architect**: StarPunk Architect Subagent
|
||||
**Developer**: Agent-Developer
|
||||
**Status**: Ready for Implementation
|
||||
|
||||
## Quick Summary
|
||||
|
||||
**Problem**: Delete route doesn't check if note exists before deletion, always shows "success" message even for nonexistent notes.
|
||||
|
||||
**Solution**: Add existence check (4 lines) before confirmation check, return 404 with error message if note doesn't exist.
|
||||
|
||||
**Result**: Final failing test will pass (406/406 tests ✅)
|
||||
|
||||
## Exact Implementation
|
||||
|
||||
### File to Edit
|
||||
|
||||
`/home/phil/Projects/starpunk/starpunk/routes/admin.py`
|
||||
|
||||
### Function to Modify
|
||||
|
||||
`delete_note_submit()` (currently lines 173-206)
|
||||
|
||||
### Code to Add
|
||||
|
||||
**Insert after line 192** (after docstring, before confirmation check):
|
||||
|
||||
```python
|
||||
# Check if note exists first (per ADR-012)
|
||||
existing_note = get_note(id=note_id, load_content=False)
|
||||
if not existing_note:
|
||||
flash("Note not found", "error")
|
||||
return redirect(url_for("admin.dashboard")), 404
|
||||
|
||||
```
|
||||
|
||||
### Complete Function After Change
|
||||
|
||||
```python
|
||||
@bp.route("/delete/<int:note_id>", methods=["POST"])
|
||||
@require_auth
|
||||
def delete_note_submit(note_id: int):
|
||||
"""
|
||||
Handle note deletion
|
||||
|
||||
Deletes a note after confirmation.
|
||||
Requires authentication.
|
||||
|
||||
Args:
|
||||
note_id: Database ID of note to delete
|
||||
|
||||
Form data:
|
||||
confirm: Must be 'yes' to proceed with deletion
|
||||
|
||||
Returns:
|
||||
Redirect to dashboard with success/error message
|
||||
|
||||
Decorator: @require_auth
|
||||
"""
|
||||
# Check if note exists first (per ADR-012) ← NEW
|
||||
existing_note = get_note(id=note_id, load_content=False) ← NEW
|
||||
if not existing_note: ← NEW
|
||||
flash("Note not found", "error") ← NEW
|
||||
return redirect(url_for("admin.dashboard")), 404 ← NEW
|
||||
|
||||
# Check for confirmation
|
||||
if request.form.get("confirm") != "yes":
|
||||
flash("Deletion cancelled", "info")
|
||||
return redirect(url_for("admin.dashboard"))
|
||||
|
||||
try:
|
||||
delete_note(id=note_id, soft=False)
|
||||
flash("Note deleted successfully", "success")
|
||||
except ValueError as e:
|
||||
flash(f"Error deleting note: {e}", "error")
|
||||
except Exception as e:
|
||||
flash(f"Unexpected error deleting note: {e}", "error")
|
||||
|
||||
return redirect(url_for("admin.dashboard"))
|
||||
```
|
||||
|
||||
## Why This Fix Works
|
||||
|
||||
1. **Checks existence FIRST**: Before user confirmation, before deletion
|
||||
2. **Returns 404**: Proper HTTP status for nonexistent resource (per ADR-012)
|
||||
3. **Flash error message**: Test expects "error" or "not found" in response
|
||||
4. **Consistent pattern**: Matches update route implementation exactly
|
||||
|
||||
## Testing
|
||||
|
||||
### Run Failing Test
|
||||
|
||||
```bash
|
||||
uv run pytest tests/test_routes_admin.py::TestAdminDeleteRoutes::test_delete_nonexistent_note_shows_error -v
|
||||
```
|
||||
|
||||
**Expected**: PASSED ✅
|
||||
|
||||
### Run Full Test Suite
|
||||
|
||||
```bash
|
||||
uv run pytest
|
||||
```
|
||||
|
||||
**Expected**: 406/406 tests passing ✅
|
||||
|
||||
## Implementation Checklist

||||
|
||||
- [ ] Edit `/home/phil/Projects/starpunk/starpunk/routes/admin.py`
|
||||
- [ ] Add 4 lines after line 192 (after docstring)
|
||||
- [ ] Verify `get_note` is already imported (line 15) ✅
|
||||
- [ ] Run failing test - should pass
|
||||
- [ ] Run full test suite - should pass (406/406)
|
||||
- [ ] Document changes in `docs/reports/`
|
||||
- [ ] Update changelog
|
||||
- [ ] Increment version per `docs/standards/versioning-strategy.md`
|
||||
- [ ] Follow git protocol per `docs/standards/git-branching-strategy.md`
|
||||
|
||||
## Architectural Rationale
|
||||
|
||||
### Why Not Change delete_note() Function?
|
||||
|
||||
The `delete_note()` function in `starpunk/notes.py` is intentionally idempotent:
|
||||
- Deleting nonexistent note returns success (no error)
|
||||
- This is correct REST behavior for data layer
|
||||
- Supports retry scenarios and multiple clients
|
||||
|
||||
**Separation of Concerns**:
|
||||
- **Data Layer** (`notes.py`): Idempotent operations
|
||||
- **Route Layer** (`admin.py`): HTTP semantics (404 for missing resources)
|
||||
|
||||
### Why Check Before Confirmation?
|
||||
|
||||
**Order matters**:
|
||||
1. ✅ Check existence → error if missing
|
||||
2. ✅ Check confirmation → cancel if not confirmed
|
||||
3. ✅ Perform deletion → success or error
|
||||
|
||||
**Alternative** (check after confirmation):
|
||||
1. Check confirmation
|
||||
2. Check existence → error if missing
|
||||
|
||||
**Problem**: User confirms deletion, then gets 404 (confusing UX)
|
||||
|
||||
## Performance Impact
|
||||
|
||||
**Added overhead**: One database query (~0.1ms)
|
||||
- SELECT query to check existence
|
||||
- No file I/O (load_content=False)
|
||||
- Acceptable for single-user CMS

- **Implementation Spec**: `/home/phil/Projects/starpunk/docs/reports/delete-route-implementation-spec.md`
|
||||
- **ADR-012**: HTTP Error Handling Policy (`/home/phil/Projects/starpunk/docs/decisions/ADR-012-http-error-handling-policy.md`)
|
||||
- **Similar Fix**: Update route (lines 148-152 in `admin.py`)
|
||||
|
||||
## What Happens After This Fix
|
||||
|
||||
**Test Results**:
|
||||
- Before: 405/406 tests passing (99.75%)
|
||||
- After: 406/406 tests passing (100%) ✅
|
||||
|
||||
**Phase Status**:
|
||||
- Phase 4 (Web Interface): 100% complete ✅
|
||||
- Ready for Phase 5 (Micropub API)
|
||||
|
||||
**ADR-012 Compliance**:
|
||||
- All admin routes return 404 for nonexistent resources ✅
|
||||
- All routes check existence before operations ✅
|
||||
- Consistent HTTP semantics across application ✅
|
||||
|
||||
## Developer Notes
|
||||
|
||||
1. **Use uv**: All Python commands need `uv run` prefix (per CLAUDE.md)
|
||||
2. **Git Protocol**: Follow `docs/standards/git-branching-strategy.md`
|
||||
3. **Documentation**: Update `docs/reports/`, changelog, version
|
||||
4. **This is the last failing test**: After this fix, all tests pass!
|
||||
|
||||
## Quick Reference
|
||||
|
||||
**What to add**: 4 lines (existence check + error handling)
|
||||
**Where to add**: After line 192, before confirmation check
|
||||
**Pattern to follow**: Same as update route (line 148-152)
|
||||
**Test to verify**: `test_delete_nonexistent_note_shows_error`
|
||||
**Expected result**: 406/406 tests passing ✅
