Database and test data

DB management, migrations and more​

The tobira db subcommand (usually via cargo run -- db) contains a number of useful tools to manage the database. Run db --help to find out more.

Whenever you change existing DB migrations, Tobira won't start. You can fix that by either purging the DB and rerunning all migrations, but that obviously also deletes all your data. You can do that with cargo run -- db reset. Another option for when the migration change doesn't actually change anything in the DB (e.g. a comment change), is to use cargo run -- db unsafe-overwrite-migrations.

Test data​

A freshly started Tobira instance doesn't have any data in it. We provide some dummy data that you can use for development.

Run the following command, which downloads a roughly 3MB DB dump and imports it into your dev DB. This is roughly the same data you can see on tobira.opencast.org.

./x.sh db load-dump
tip

We recommend always working with the dataset that is closest to production use cases and thus also contains messy real world data. That way, you immediately notice problems which you might not catch on a tiny dataset with polished data. These problems range from DB query performance to UI design.

Tiny dataset​

In backend/ run this:

cargo run -- db script ../util/fixtures.sql

Your own Opencast data​

First, sync video/series data:

  • cp util/dev-config/config.toml util/dev-config/sync-config.toml
  • Change the sync section of the new file to contain the correct credentials for your Opencast instance.
  • In backend/, run cargo run -- sync run -c ../util/dev-config/sync-config.toml

To get some realms (pages), either manually create some or import a file containing dummy realms. To import, run this in backend/: cargo run -- import-realm-tree <file>. <file> is .deployment/files/realms.yaml (big) or util/dummy-realms.yaml (small). You might want to pass --dummy-blocks as well.
