facts generation

Sample of customer.yaml

facts_finder:
   CustomDeviceFactsClass: !!python/name:custom_factsgen.CustomDeviceFacts ''
   foreign_keys: !!python/name:custom_factsgen.FOREIGN_KEYS ''

Where, We have a class named CustomDeviceFacts in a package custom_factsgen. [ referenced as CustomDeviceFactsClass] Similarly, we have a dictionary defined named FOREIGN_KEYS in a package custom_factsgen. [ referenced as foreign_keys]

CustomDeviceFactsClass: A class which takes cleaned facts dictionary as argument and work on it, to derive the additional custom attributes, required to be added to clean output file. foreign_keys: A Dictionary with list of additional fields required to be added to clean excel file. ( custom fields mentioned here, only those will be permitted to be add in clean files.)

Sample Foreign key dictionary:

FOREIGN_KEYS = {
   'bgp':[ "router_id", ],
   'vrf':["vrf_vpnid", "vrfcolor", ],
   'interfaces':[ "int_type",  "int_type", "int_description", ],
}
