# Design Decision
## Communication between Browser and Server via REST-like Endpoints and HTMX
- https://htmx.org/essays/10-tips-for-ssr-hda-apps/
- Name of endpoints is plural
    - "/locations" GET -> read all
    - "/locations/new" GET / POST -> create
    - "/locations/1" GET -> edit, POST -> update, DELETE -> delete CRUD
    - "/locations/assign" GET / POST for custom action
- Modelling of models in code
    - see vehicle.rs
    - use of applicationError
    - return Options, where queries are bound to id or search input

## Testing
### User
- CreatingNewUser_AsAdmin_SendsRegistrationMail

## Data Layer
- use model structs for the exact represenation in databse (maybe sometimes a field is not used in code, then its maybe fine to drop it off the struct e.g. Timestamp at Token tables)
- use changesset struct based on model (wihout ids)
    - groups parametres for methods
    - allows validation on fields (ecto changeset, elm js data down actions up)
    - all fields are as they are on the model, all field must be supplied; no way for "partial updates"
- partial updates for only one or two fields get a special method on the model
- validate using garde and custom context with gives access to database pool
