Ansible: fortigate list to popolate a dictionary

remote_address_phase2:
  - 192.168.88.0/24
  - 192.168.1.0/24

task:

i have to create a firewall group 

  - name: "addrgrp"
    fortios_firewall_addrgrp:
      vdom:  "{{ vdom }}"
      state: "present"
      firewall_addrgrp:
        allow_routing: "disable"
        #category: "default"
        color: "21"
        comment: "try"
        exclude: "disable"
        fabric_object: "disable"
        member:
          - name: "NET-{{ item}}"
      
        name: "try"

        type: "default"

    with_items:  "{{  remote_address_phase2 }}"

if i made this activity i have 2 different task but the last operation overwrite the first

any idea?

Going by the example in the documentation for the module, it seems that the member: parameter takes a list of dicts.

Example from module documentation:

        member:
         -
            name: "default_name_7 (source firewall.address.name firewall.addrgrp.name)"

Haven't tested it, but we can create a similar structure before "addrgrp" task with set_fact and use the newly created variable.

    - set_fact:
        fw_members: "{{ fw_members | default([]) + [{'name': 'NET-' ~ item}] }}"
      loop: "{{ remote_address_phase2 }}"

This gives:

    "fw_members": [
        {
            "name": "NET-192.168.88.0/24"
        },
        {
            "name": "NET-192.168.1.0/24"
        }
    ]

It should then be possible to pass this variable as a value to the member: parameter. Example:

  - set_fact:
      fw_members: "{{ fw_members | default([]) + [{'name': 'NET-' ~ item}] }}"
    loop: "{{ remote_address_phase2 }}"

  - name: "addrgrp"
    fortios_firewall_addrgrp:
      vdom:  "{{ vdom }}"
      state: "present"
      firewall_addrgrp:
        allow_routing: "disable"
        #category: "default"
        color: "21"
        comment: "try"
        exclude: "disable"
        fabric_object: "disable"
        member: "{{ fw_members }}"
        name: "try"
        type: "default"
