Rational record of one going to California (7)
I believe the answer is:
logical
'rational' is the definition.
(associated in meaning)
'record of one going to california' is the wordplay.
'record' becomes 'log' (log is a kind of record).
'of one' becomes 'i' (I've seen this in other clues).
'going to' is a charade indicator (letters next to each other).
'california' becomes 'cal' (short for California).
'log'+'i'+'cal'='LOGICAL'
(Other definitions for logical that I've seen before include "Well-reasoned" , "Based on reason" , "Well reasoned" , "Following correct reasoning" , "Correctly reasoned, makes sense" .)
