TODO: Not all the information is provided there.
This commit provides an unstable JSON API for communication with an
upcoming Dart frontend.
Later it might be part of the public interface for integration into
other services. For this step it has to be ensured the semantics are not
changing a lot in the future which is currently out of scope.
Introduce model.Transaction()2024-05-08T20:26:00Zxengineeringme@xengineering.eu2024-05-08T19:53:13Zurn:sha1:0ba1a7661a81200db98e40149eef1e39fd22f407
It is a very common pattern that some function needs to access the
database and wants to wrap all the actions into one transaction.
The advantage of a transaction is that it is ACID:
- atomic
- consistent
- isolated
- durable
In Go it is required to request a new transaction, execute functionality
on it and handle rollback or commit of this transaction based on the
success of the operation.
All this and the error handling can be written down in the
model.Transaction() function exactly once. The full signature of it is:
func Transaction(f func(*sql.Tx) error) error
It requires a function or closure passed as argument which takes the
transaction (*sql.Tx) and returns an error which might be nil.
This is very generic. It is applied to:
- injecting test data
- database migrations
- data read requests
- data write requests
model: Add helper function for safe CRUD2024-04-07T08:47:36Zxengineeringme@xengineering.eu2024-04-07T08:42:03Zurn:sha1:c4a4a8b5f60a568abd2af614ca4a5d06855bc3a1
This removes the redundant setup of a database/sql.Tx in each HTTP
handler.
model: Add model.Object interface2024-04-07T08:26:20Zxengineeringme@xengineering.eu2024-04-06T18:56:49Zurn:sha1:537bbcea3b2477eeae7d86422a073558185cf4eb
This interface will allow to implement generic functions based on the
Object interface which covers the four CRUD methods create, read, update
and delete.
This should be possible for every object handled by the server.
