Cisco DNA Template - Working with Lists?

[magwes]

I'm trying to create a simple template i DNAC that loops through the switches in a stack, appends the number of ports found in the product name of each switch into a list.

Using this link as reference : Platinum-PortAssign-Template.j2 

Code:

{% set StackPIDs = __device.platformId | split(",")  %}
{% set StackMemberCount = StackPIDs | length  %}
{% set PortTotal = [] %}
{% set Model = '' %}
{% for Switch in range(StackMemberCount) %}
  {% set Model = StackPIDs[Switch] %}
  {% if '48' in Model -%}
    {% set PortTotal = PortTotal.append(48) %}
  {% elif '24' in Model %}
    {% set PortTotal = PortTotal.append(24) %}
  {% endif %}
{% endfor %}
{{ PortTotal }}

This works fine when there is only one switch in the stack, but with 2 or more it fails with "Cannot find method append with 1 parameters in class java.lang.Boolean".

What am I doing wrong? Or is this a bug in DNAC?

Best regards
Magnus

I have no experience in this field
but maybe you need to add the member-ID somewhere ?
like Port.Total[switch].append(48)

Hi Magwes
The error is clearly stating the append operator is having issues...
Thats because in my haste to put code up there somehow this one did not get tested...

I have amended it now, but the conditional block should read as shown here...

{% if '48' in Model -%}
       {% do PortTotal.append(48) %}
{% elif '24' in Model %}
       {% do PortTotal.append(24) %}
{% endif %}

Hope that helps...
