pangea.core.models.analysis_result module

class pangea.core.models.analysis_result.AnalysisResult(*args, **kwargs)

Bases: pangea.core.mixins.AutoCreatedUpdatedMixin

Represent a single field of a single result in the database.

Example:

KrakenUniq produces a table of read-classifications and a report. These are stored separately as two separate AnalysisResults. Both ARs have the same module_name (e.g. KrakenUniq) Both ARs have the same owner (e.g. sample-123) Both ARs have different a field_name (e.g. report or read_class).

owner_uuid should reference a group or sample. Whether it is a group or sample is determined by owned_by_group. This is only enforced in code. The reverse (sample->AR or group->AR) is enforced in SQL. AR Fields carry a status marker. In principle all fields of an ARs always have the same status.
