# 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
