Get a Teacher Relocation Payment - 3. Update domain: extract school

Date: 2023-06-12

Status

Accepted

Context

The information about the school: name, postcode and headteacher name is currently stored in the Applicant. As we are adding more functionality and validations to the Applicant journey, we are finding ourselves with code that does not look easy to read and reason about.

For example, the applicant domain class has two postcodes:

1. Postcode for his address (postcode)
2. Postcode for the school (school_postcode)

This also happens for the name, and will happen for more attributes as we have been requested to also add the school address.

Decision

Extract the School domain class that stores:

• name
• postcode
• headteacher name

School will have a FK to Applicant in a one-to-one association. If the applicant is removed then the school will be removed as well.

Although column names will change over time, the eventual table structure will look something like this:

Consequences

This will make the Applicant domain class easier to read and reason about, although the domain will be a bit more complex.
