+# Django DurationField Error Message Format Correction
|
||||
+
|
||||
+## Issue
|
||||
+The `DurationField` error message in Django incorrectly displayed the duration format. When users entered an invalid duration, they received an error message stating the format should be:
|
||||
+
|
||||
+```
|
||||
+[DD] [HH:[MM:]]ss[.uuuuuu]
|
||||
+```
|
||||
+
|
||||
+However, this format specification is **incorrect**. According to the actual behavior of the `parse_duration()` function, the correct format should be:
|
||||
+
|
||||
+```
|
||||
+[DD] [[HH:]MM:]ss[.uuuuuu]
|
||||
+```
|
||||
+
|
||||
+## Analysis
|
||||
+
|
||||
+### Format Breakdown
|
||||
+
|
||||
+Looking at the `standard_duration_re` regex pattern in `django/utils/dateparse.py`:
|
||||
+
|
||||
+```python
|
||||
+standard_duration_re = re.compile(
|
||||
+ r'^'
|
||||
+ r'(?:(?P<days>-?\d+) (days?, )?)?' # Optional: days
|
||||
+ r'(?P<sign>-?)' # Optional: sign
|
||||
+ r'((?:(?P<hours>\d+):)(?=\d+:\d+))?' # Optional: hours (only if MM:ss follows)
|
||||
+ r'(?:(?P<minutes>\d+):)?' # Optional: minutes
|
||||
+ r'(?P<seconds>\d+)' # REQUIRED: seconds
|
||||
+ r'(?:\.(?P<microseconds>\d{1,6})\d{0,6})?' # Optional: microseconds
|
||||
+ r'$'
|
||||
+)
|
||||
+```
|
||||
+
|
||||
+### Key Differences
|
||||
+
|
||||
+| Component | Status | Old Format | New Format |
|
||||
+|-----------|--------|-----------|-----------|
|
||||
+| Days | Optional | `[DD]` | `[DD]` |
|
||||
+| Hours | Optional (only with MM) | `[HH:[MM:]]` | `[[HH:]MM:]` |
|
||||
+| Minutes | Optional | Implied in Hours | Explicit as `MM` |
|
||||
+| Seconds | **MANDATORY** | `ss` | `ss` |
|
||||
+| Microseconds | Optional | `[.uuuuuu]` | `[.uuuuuu]` |
|
||||
+
|
||||
+### Why the Difference?
|
||||
+
|
||||
+The old format `[HH:[MM:]]ss` implies that:
|
||||
+- Hours are optional
|
||||
+- If hours are present, minutes are optional
|
||||
+- But this doesn't clearly show that **minutes are required if hours are present**
|
||||
+
|
||||
+The new format `[[HH:]MM:]ss` correctly shows that:
|
||||
+- Hours and minutes form an optional group: `[[HH:]MM:]`
|
||||
+- Minutes MUST be present if hours are present
|
||||
+- Seconds are always required
|
||||
+
|
||||
+### Valid Examples
|
||||
+
|
||||
+All these formats are valid according to the regex:
|
||||
+- `14` → 14 seconds
|
||||
+- `14:00` → 14 minutes, 0 seconds
|
||||
+- `1:14:00` → 1 hour, 14 minutes, 0 seconds
|
||||
+- `1 1:14:00` → 1 day, 1 hour, 14 minutes, 0 seconds
|
||||
+- `14:00:00.123456` → 14 hours, 0 minutes, 0 seconds, 123456 microseconds
|
||||
+- `10:30` → 10 minutes, 30 seconds
|
||||
+
|
||||
+## Solution
|
||||
+
|
||||
+The fix involves updating the error message format string in **two files**:
|
||||
+
|
||||
+### 1. `django/db/models/fields/__init__.py` (Line 1590)
|
||||
+
|
||||
+**Before:**
|
||||
+```python
|
||||
+default_error_messages = {
|
||||
+ 'invalid': _("'%(value)s' value has an invalid format. It must be in "
|
||||
+ "[DD] [HH:[MM:]]ss[.uuuuuu] format.")
|
||||
+}
|
||||
+```
|
||||
+
|
||||
+**After:**
|
||||
+```python
|
||||
+default_error_messages = {
|
||||
+ 'invalid': _("'%(value)s' value has an invalid format. It must be in "
|
||||
+ "[DD] [[HH:]MM:]ss[.uuuuuu] format.")
|
||||
+}
|
||||
+```
|
||||
+
|
||||
+### 2. `tests/model_fields/test_durationfield.py` (Line 78)
|
||||
+
|
||||
+**Before:**
|
||||
+```python
|
||||
+"It must be in [DD] [HH:[MM:]]ss[.uuuuuu] format."
|
||||
+```
|
||||
+
|
||||
+**After:**
|
||||
+```python
|
||||
+"It must be in [DD] [[HH:]MM:]ss[.uuuuuu] format."
|
||||
+```
|
||||
+
|
||||
+## Impact
|
||||
+
|
||||
+- **Minimal change**: Only 2 lines modified in 2 files
|
||||
+- **User-facing**: The error message users receive will now accurately reflect the accepted duration format
|
||||
+- **Backward compatibility**: No code behavior changes, only the error message text
|
||||
+- **Test update**: The test validates that the error message matches the implementation
|
||||
+
|
||||
+## Verification
|
||||
+
|
||||
+The fix has been verified by:
|
||||
+1. Confirming the regex pattern in `django/utils/dateparse.py`
|
||||
+2. Testing multiple valid duration formats against the regex
|
||||
+3. Ensuring all test cases pass with the updated error message
