🔧 Bug #1: Reserved SQLAlchemy Keyword

Error

sqlalchemy.exc.InvalidRequestError: Attribute name 'metadata' is reserved when using the Declarative API.

Root Cause

The Activity model used metadata as a column name, which is reserved by SQLAlchemy.

Fix

• Renamed metadata column to extra_data in both model and migration
• Updated all references to use extra_data
• Maintained backward compatibility in API methods

Files Modified

1. app/models/activity.py - Renamed column and updated methods
2. migrations/versions/add_quick_wins_features.py - Updated migration
3. app/routes/time_entry_templates.py - Updated Activity.log call

Code Changes

# Before
metadata = db.Column(db.JSON, nullable=True)
Activity.log(..., metadata={...})

# After
extra_data = db.Column(db.JSON, nullable=True)
Activity.log(..., extra_data={...})

🔧 Bug #2: Wrong Import Source for 'db'

Error

ImportError: cannot import name 'db' from 'app.models'

Root Cause

Route files tried to import db from app.models, but it's defined in app/__init__.py.

Fix

Changed imports from from app.models import ..., db to separate imports.

Files Modified

1. app/routes/time_entry_templates.py
2. app/routes/saved_filters.py

Code Changes

# Before (WRONG)
from app.models import TimeEntryTemplate, Project, Task, db

# After (CORRECT)
from app import db
from app.models import TimeEntryTemplate, Project, Task

---

🔧 Bug #3: Wrong Module Name for Utilities

Error

ModuleNotFoundError: No module named 'app.utils.db_helpers'

Root Cause

Route files tried to import from app.utils.db_helpers, but the actual module is app.utils.db.

Fix

Corrected module name in imports.

Files Modified

1. app/routes/time_entry_templates.py
2. app/routes/saved_filters.py

Code Changes

# Before (WRONG)
from app.utils.db_helpers import safe_commit

# After (CORRECT)
from app.utils.db import safe_commit

---

🔧 Bug #4: Missing Form Parsing for Prepaid Fields

Error

NameError: name 'prepaid_hours_input' is not defined

Root Cause

The client edit route validated prepaid_hours_input and prepaid_reset_day_input but never read those form fields, causing a NameError when users tried to update prepaid hours.

Fix

• Parse prepaid_hours_monthly and prepaid_reset_day from the form before validation
• Added regression tests to cover successful updates and negative-hour validation
• Documented the issue and fix in this summary

Files Modified

1. app/routes/clients.py - Read prepaid form fields before validation
2. tests/test_routes.py - Added route regression tests for prepaid editing
3. ALL_BUGFIXES_SUMMARY.md - Documented the fix

🔧 Bug #5: Benign ResizeObserver Warnings Flooding Error Handler

Error

ResizeObserver loop completed with undelivered notifications.

Root Cause

Certain UI components trigger harmless ResizeObserver warnings in Chromium-based browsers. These were caught by the global error handler, surfaced to users as critical toasts, and logged as console errors.

Fix

• Added noise filtering in error-handling-enhanced.js to ignore known benign ResizeObserver warnings while still logging other errors.
• Downgraded these messages to console.debug so developers can inspect them without user-facing noise.
• Updated bug summary documentation (this file).

Files Modified

1. app/static/error-handling-enhanced.js
2. ALL_BUGFIXES_SUMMARY.md

🔧 Bug #6: Invoice Actions Dropdown Hidden Behind Content

Error

Invoice row actions menu appeared underneath neighboring table content, hiding menu items from the user.

Root Cause

The dropdown relied on a modest z-index within a stacking context created by the grid/table layout. Parent cells also defaulted to clipping overflow, so the menu rendered below adjacent elements.

• Fix

• Marked the actions cell as relative overflow-visible so the dropdown can extend beyond the table cell.
• Elevated the dropdown with a dedicated class and runtime positioning logic that renders it as a floating menu (fixed to the viewport) to avoid impacting table height.
• Added scroll/resize listeners to collapse the menu when the layout changes, preventing stray overlays.
• Documented the bug in this summary.

Files Modified

1. app/templates/invoices/list.html
2. ALL_BUGFIXES_SUMMARY.md

📝 Best Practices Learned

1. Avoid SQLAlchemy Reserved Words

Never use these as column names:

• metadata
• query
• mapper
• connection

2. Correct Import Pattern for Flask-SQLAlchemy

# ✅ CORRECT
from app import db
from app.models import SomeModel

# ❌ WRONG
from app.models import SomeModel, db

3. Always Verify Module Names

Check the actual file/module structure before importing:

ls app/utils/  # Check what actually exists

🚀 Deployment Status

Status: ✅ Ready for Production

All critical startup errors have been resolved. The application should now:

1. ✅ Start without import errors
2. ✅ Initialize database models correctly
3. ✅ Load all route blueprints successfully
4. ✅ Run migrations without conflicts
