Vikunja uses xorm as an abstraction layer to handle the database connection. Please refer to their documentation on how to exactly use it.
Using the database #
When using the common web handlers, you get an xorm.Session to do database manipulations. In other packages, use the db.NewSession() method to get a new database session.
Adding new database tables #
To add a new table to the database, create the struct and add a migration for it.
To learn more about how to configure your struct to create "good" tables, refer to the xorm documentation.
In most cases you will also need to implement the TableName() string method on the new struct to make sure the table name matches the rest of the tables - plural.
Adding data to test fixtures #
Adding data for test fixtures can be done via yaml files in pkg/models/fixtures.
The name of the yaml file should match the table name in the database. Adding values to it is done via array definition inside it.
Note: Table and column names need to be in snake_case as that's what is used internally in the database and for mapping values from the database to xorm so your structs can use it.
