4.2. Customize

SO YOU DECIDED TO CUSTOMIZE. HURREY !!!

FOLLOW ALONG.

After Previous First Steps, We can now add custom classes & modules as filters to be accessible inside jinja templates.

Refer below on how to fork them in.

• module import should declare pure methods only. and should be imported as full module

• Classes should be imported explicitely from diverse modules.

# -------------------------------------------------------------------------------------------------------------
# Custom Project Imports (Optional/Additional), sample project imports mentioned as below. (modify as per own)
# -------------------------------------------------------------------------------------------------------------
from custom.custom_j2config.classes import Summaries, Vrf, Vlan, Bgp, Physical # filter classes import
from custom.custom_j2config import module1                                     # import full module(s), consisting filter methods

# -------------------------------------------------------------------------------------------------------------
# Input all Additional filter classes as a Dictionary, can be called using their Key.
# -------------------------------------------------------------------------------------------------------------
custom_classes = {
    'Summaries': Summaries,
    'Vrf': Vrf,
    'Vlan': Vlan,
    'Bgp': Bgp,
    'Physical': Physical,
    ## add more classes as necessary, after import ##
}

# -------------------------------------------------------------------------------------------------------------
# Input all Additional filter modules containing methods to a set.
# -------------------------------------------------------------------------------------------------------------
custom_modules = {module1, }                                                ## add more modules as necessary, after import

# -------------------------------------------------------------------------------------------------------------
# Fork in all custom classes and modules to PrepareConfig object instance using below methods.
# -------------------------------------------------------------------------------------------------------------
PrCfg.custom_class_add_to_filter(**custom_classes)
PrCfg.custom_module_methods_add_to_filter(*custom_modules)

Note

Congratulations!!!

1. Now you can access custom declared classes/methods from within jinja template as filters.

2. And you already override device var database using custom regional_file database in previous step.

It is soleley users responsiblity for providing appropriate filters as custom_classes and custom_modules, as well as deploying those appropriately in jinja templates.
