Template Use html Property

[k-macmillan]

User Story - Business Need

Generate email template html and text once and use substitution for personalization.

• Ticket is understood, and QA has been contacted (if the ticket has a QA label).

User Story(ies)

As a VA Notify client
I want my template to be locked in when I've hit the save button
So that any changes on the VA Notify side do not affect the emails I send

Additional Info and Resources

• Python property

Acceptance Criteria

• Feature flag
• template.html generates the html if it does not exist, otherwise it returns the html
• template.text generates the text if it does not exist, otherwise it returns the text
• Personalization is substituted correctly into the saved html and text when the email is sent
  • Personalization does not change the template record
• This work is added to the sprint review slide deck (key win bullet point and demo slide)

QA Considerations

Email recipients should experience no difference between pre and post deployment of this work.

Potential Dependencies

• Database fields
• Portal needs to save data to the _html and _text fields - collab with Strike

Had a conversation with David K., and the idea is to test with Postman by:

1. Create a template.
2. Retrieve it a couple of times. Watch in datadog for renders.
3. Send and email and watch for renders.
4. Update the template and repeat.

I am working on pulling some of the notifiation-utils code into the send-to-providers module in api. Currently the prefixing and fragment count are causing test failures. PR should be forthcoming after those failures are fixed.
