#save! ⇒ Object

Swivel::Connection#create_graph returns a transient graph that must be saved in order for it to persist at Swivel. Only persistent graphs have page urls at Swivel.

call save on a transient graph in order to do this.

# create a transient graph
transient_graph = swivel.create_graph {...}
transient_graph.variant # => 'transient'
transient_graph.id.blank? # => true

# persist the transient graph
persisted_graph = transient_graph.save
persisted_graph.variant # => 'default'
persisted_graph.id.blank? # false

# now, you can grab it from swivel whenever
g = swivel.graph persisted_graph.id
g.name == persisted_graph.name # => true
