Possible DSL for building conditional fields

It should take care of
- conditional `required` validation 
- passing the `conditional` html to the frontend component
- preserving ordering of errors
- blanking values if the matching option is deselected

Some authorization options for python apps

Django-specific

django.contrib.auth

Comes with ModelBackend - an authorization system based on permissions stored in the database. You need to assign to user or groups.

By default there are CRUD permissions created per model, which is very granular. You can also define custom permissions at a model level.

Pros:

Rails	Django	Description
preload	prefetch_related	one query per table
eager_load	select_related	one query with joins
includes	N/A	same as preload if associated table not references, otherwise eager_load

Cost/licensing

• Gitleaks is MIT licensed. However gitleaks-action has a non-standard license which requires registering (for free)
• Github offers secret scanning on all public repos
• For private repos, there is Github secret protection, which requires a GitHub Team or GitHub Enterprise Cloud account.

What's detected

• Github secret scanning - note that "non-provider" patterns are enabled separately, and there is a separate AI tool under the Copilot brand.

Nunjucks / Jinja compatibility spike

Purpose of spike

Nunjucks templates are almost (but not quite) compatible with Jinja.

We wanted to find out if we could adapt existing templates written for Nunjucks so that they would render in Jinja.

Specifically, we wanted to understand what would be involved in making nhs-frontend Nunjucks templates cross-compatible with Jinja.

Background

For the fundamentals of using forms in HTML, see the MDN forms tutorial

In particular, Sending and retrieving form data

Key things to keep in mind

• Each form control needs to be associated with a label for accessibility
• All named form elements send a value back to the server
• In the case of GET requests, values go into the URL as a query parameter
