SubmissionType

pretalx.submission.models.type.SubmissionType source

Each Submission has one SubmissionType.

SubmissionTypes are used to group submissions by default duration (which can be overridden on a per-submission basis), and to be able to offer different deadlines for some parts of the Event.
