TruxtonRelation

This class lets you add to the Relation table in Truxton. This is how to establish some sort of relation between items in Truxton to create a graph.

Attributes and Methods

a

This is the GUID of the object. This combined with atype allows Truxton to retrieve the correct record from the database. This is also known as a vertex in a graph.

atype

The type of the thing that a represents. This corresponds to the A_ObjectTypeID column of the Relation table. It should contain a value in the ID column of the ObjectType table or you can use a defined constant.

b

This is the GUID of the object. This combined with btype allows Truxton to retrieve the correct record from the database

btype

The type of the thing that b represents. This corresponds to the B_ObjectTypeID column of the Relation table. It should contain a value in the ID column of the ObjectType table or you can use a defined constant.

relation

This provides the reason why a and b are related. This corresponds to the A_ObjectTypeID column of the Relation table. It is known as an edge in a graph.

source

This is the GUID of the object this relation came from. This combined with sourcetype allows Truxton to retrieve the correct record from the database.

sourcetype

The type of the thing that source represents. This corresponds to the B_ObjectTypeID column of the Relation table. It should contain a value in the ID column of the ObjectType table or you can use a defined constant.

save()

This will commit the information to the Relation table. It will return True if the record was saved to the database, False if there was an error.
