Task 5 Requirements Checklist

Task: Backend: Implement PUT endpoint for updating custom status

Requirements Coverage

✅ Requirement 2.1: Support updating name

Implementation:

# Validate name uniqueness if name is being changed
if status_update.name is not None and status_update.name != status_to_update.get('name'):
    # Check against other custom statuses
    existing_names = [
        s.get('name', '').lower() 
        for i, s in enumerate(custom_statuses_data) 
        if isinstance(s, dict) and i != status_index
    ]
    
    # Check against system statuses
    system_names = [s['name'].lower() for s in SYSTEM_TASK_STATUSES]
    
    if status_update.name.lower() in existing_names:
        raise HTTPException(status_code=409, ...)
    
    if status_update.name.lower() in system_names:
        raise HTTPException(status_code=409, ...)
    
    # Update name
    status_to_update['name'] = status_update.name

Verified:

• ✅ Name can be updated
• ✅ Name validation works
• ✅ Uniqueness check implemented
• ✅ Returns updated status

---

✅ Requirement 2.2: Support updating color

Implementation:

# Update color if provided
if status_update.color is not None:
    status_to_update['color'] = status_update.color

Verified:

• ✅ Color can be updated
• ✅ Color format validated by schema (hex codes)
• ✅ Color updates independently of other fields
• ✅ Returns updated status

---

✅ Requirement 2.3: Support updating is_default flag

Implementation:

# Handle is_default flag
if status_update.is_default is not None:
    if status_update.is_default:
        # If setting as default, unset other default statuses
        for status_data in custom_statuses_data:
            if isinstance(status_data, dict):
                status_data['is_default'] = False
        
        # Set this status as default
        status_to_update['is_default'] = True
    else:
        # Just unset this status as default
        status_to_update['is_default'] = False

Verified:

• ✅ is_default flag can be updated
• ✅ Can set status as default
• ✅ Can unset status as default
• ✅ Returns updated status

---

✅ Requirement 5.2: If setting as default, unset other default statuses

Implementation:

if status_update.is_default:
    # If setting as default, unset other default statuses
    for status_data in custom_statuses_data:
        if isinstance(status_data, dict):
            status_data['is_default'] = False
    
    # Set this status as default
    status_to_update['is_default'] = True

Verified:

• ✅ When setting a status as default, all other defaults are unset
• ✅ Only one default status exists at a time
• ✅ Default status ID is correctly returned in response
• ✅ Previous default is properly unset

---

✅ Additional Requirement: Validate name uniqueness if name is changed

Implementation:

# Validate name uniqueness if name is being changed
if status_update.name is not None and status_update.name != status_to_update.get('name'):
    # Check against other custom statuses
    existing_names = [...]
    
    # Check against system statuses
    system_names = [...]
    
    if status_update.name.lower() in existing_names:
        raise HTTPException(status_code=409, ...)
    
    if status_update.name.lower() in system_names:
        raise HTTPException(status_code=409, ...)

Verified:

• ✅ Name uniqueness validated within project
• ✅ Checks against other custom statuses
• ✅ Checks against system status names
• ✅ Returns 409 Conflict on duplicate

---

✅ Additional Requirement: Use flag_modified for JSON column updates

Implementation:

# Update the status in the list
custom_statuses_data[status_index] = status_to_update
db_project.custom_task_statuses = custom_statuses_data

# Use flag_modified for JSON column updates
flag_modified(db_project, 'custom_task_statuses')

try:
    db.commit()
    db.refresh(db_project)
except Exception as e:
    db.rollback()
    raise HTTPException(...)

Verified:

• ✅ flag_modified is used
• ✅ Changes persist to database
• ✅ JSON column updates work correctly
• ✅ Rollback on error

---
