You should try using the --calc-missing action <http://weewx.com/docs/utilities.htm#Action_--calc-missing> with wee_database. --calc-missing will calculate any missing derived observations in your database, rainRate is a derived observation as far as WeeWX is concerned, you may have prefer_hardware against rainRate in StdWXCalculate but that should not matter in this case (prefer_hardware simply means try to get the observation from the station/driver and if you can't calculate it). wee_database does not interrogate your station/driver for data in any way.
Note that for wee_database to consider an observation to be 'missing' the corresponding database field(s) must be empty or have been set to null/None. Being set to 0 (zero) is not considered empty nor is saving a zero length string (as can happen sometimes when using a graphical frontend to edit your database) and hence will not be re-calculated. Assuming you are dealing with a small segment of your data, you may wish to use the --from and --to command line options when using --calc-missing to limit the date span to be re-calculated.
