# Template Errors Fix - Complete Summary
|
|
|
|
## Date
|
|
February 21, 2026
|
|
|
|
## Overview
|
|
This document summarizes the comprehensive fixes for multiple template and URL reference errors encountered during testing and development.
|
|
|
|
## Issues Fixed
|
|
|
|
### 1. Original NoReverseMatch Error
|
|
**Error:** `Reverse for 'list' not found. 'list' is not a valid view function or pattern name.`
|
|
**Location:** `templates/dashboard/command_center.html` line 147
|
|
**Cause:** The URL tag was using `complaints:list` but the actual URL name was `complaints:complaint_list`
|
|
**Fix:** Changed `{% url 'complaints:list' %}` to `{% url 'complaints:complaint_list' %}`
|
|
|
|
### 2. Pagination Template Error
|
|
**Error:** `TemplateDoesNotExist at /organizations/patients/ : includes/pagination.html`
|
|
**Location:** `templates/organizations/patient_list.html` line 86
|
|
**Cause:** The template was trying to include `includes/pagination.html` which didn't exist
|
|
**Fix:** Replaced the `{% include %}` tag with inline pagination code following the pattern used in other templates
|
|
|
|
### 3. Base Template Path Errors
|
|
**Error:** `TemplateDoesNotExist: base.html`
|
|
**Cause:** Multiple templates were extending `'base.html'` instead of the correct `'layouts/base.html'`
|
|
**Files Fixed:**
|
|
1. `templates/organizations/patient_detail.html`
|
|
2. `templates/organizations/patient_form.html`
|
|
3. `templates/organizations/patient_confirm_delete.html`
|
|
4. `templates/surveys/bulk_job_status.html`
|
|
5. `templates/surveys/bulk_job_list.html`
|
|
|
|
**Fix:** Changed `{% extends 'base.html' %}` to `{% extends 'layouts/base.html' %}` in all affected templates
|
|
|
|
## Technical Details
|
|
|
|
### URL Name Conventions
|
|
The project uses namespaced URL patterns with descriptive names:
|
|
- `complaints:complaint_list` (not `complaints:list`)
|
|
- `complaints:complaint_detail`
|
|
- `complaints:complaint_create`
|
|
- `organizations:patient_list`
|
|
- `organizations:patient_detail`
|
|
- `surveys:instance_list`
|
|
- etc.
|
|
|
|
### Template Structure
|
|
- Base templates are located in `templates/layouts/`
|
|
- The main base template is `templates/layouts/base.html`
|
|
- Public templates use `templates/layouts/public_base.html`
|
|
- App-specific templates are in `templates/<app_name>/`
|
|
|
|
### Pagination Pattern
|
|
Pagination is implemented inline in templates using Django's paginator object:
|
|
```django
|
|
{% if is_paginated %}
|
|
<div class="flex items-center justify-between">
|
|
<div class="text-sm text-slate">
|
|
{% trans "Showing" %} {{ page_obj.start_index }}-{% trans "to" %} {{ page_obj.end_index }} {% trans "of" %} {{ page_obj.paginator.count }}
|
|
</div>
|
|
<div class="flex gap-2">
|
|
{% if page_obj.has_previous %}
|
|
<a href="?page={{ page_obj.previous_page_number }}" class="btn-secondary px-3 py-1">
|
|
{% trans "Previous" %}
|
|
</a>
|
|
{% endif %}
|
|
<span class="px-3 py-1 bg-light rounded font-medium">
|
|
{{ page_obj.number }} {% trans "of" %} {{ page_obj.paginator.num_pages }}
|
|
</span>
|
|
{% if page_obj.has_next %}
|
|
<a href="?page={{ page_obj.next_page_number }}" class="btn-secondary px-3 py-1">
|
|
{% trans "Next" %}
|
|
</a>
|
|
{% endif %}
|
|
</div>
|
|
</div>
|
|
{% endif %}
|
|
```
|
|
|
|
## Verification Steps
|
|
|
|
### 1. URL Reverse Resolution
|
|
```bash
|
|
python manage.py show_urls | grep complaints
|
|
```
|
|
Confirmed that `complaints:complaint_list` exists and `complaints:list` does not.
|
|
|
|
### 2. Template Path Verification
|
|
```bash
|
|
find templates -name "base.html"
|
|
```
|
|
Confirmed that base templates are in `templates/layouts/` directory.
|
|
|
|
### 3. Pagination Context
|
|
Verified that views provide `is_paginated`, `page_obj`, and `paginator` context variables.
|
|
|
|
## Best Practices Applied
|
|
|
|
1. **Always use explicit URL names** - Avoid generic names like "list" that might be ambiguous
|
|
2. **Follow template directory structure** - Use `layouts/` for base templates
|
|
3. **Implement pagination inline** - Avoid creating separate include files for common patterns
|
|
4. **Verify URL patterns** - Check `urls.py` files to confirm correct URL names before using them in templates
|
|
|
|
## Files Modified
|
|
|
|
1. `templates/dashboard/command_center.html` - Fixed URL reference
|
|
2. `templates/organizations/patient_list.html` - Fixed pagination implementation
|
|
3. `templates/organizations/patient_detail.html` - Fixed base template path
|
|
4. `templates/organizations/patient_form.html` - Fixed base template path
|
|
5. `templates/organizations/patient_confirm_delete.html` - Fixed base template path
|
|
6. `templates/surveys/bulk_job_status.html` - Fixed base template path
|
|
7. `templates/surveys/bulk_job_list.html` - Fixed base template path

## Conclusion
|
|
|
|
All template and URL reference errors have been resolved. The application should now:
|
|
- Successfully reverse all URL names
|
|
- Render all templates without TemplateDoesNotExist errors
|
|
- Display pagination controls correctly on list pages
|
|
- Extend the correct base templates for consistent layout
|
|
|
|
## Next Steps
|
|
|
|
1. Test the application thoroughly to ensure no other similar errors exist
|
|
2. Consider adding URL name validation to the CI/CD pipeline
|
|
3. Document URL naming conventions in the project's developer guide
|
|
4. Add unit tests to verify template rendering with proper context |
