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:

{% 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

python manage.py show_urls | grep complaints

Confirmed that complaints:complaint_list exists and complaints:list does not.

2. Template Path Verification

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
