如何在ansible中循环遍历字典值

Question

I am trying to loop through the dictionary of "key": & "Value". I am not getting proper results. I want to print the value of certain Key from a dictionary.

Here is my code:

- hosts: all
  gather_facts: false
  strategy: free
  tasks:
  - include_vars: roles/oracle/vars/install_vars.yaml
    vars:
     var_list:
        - script_name

  - set_fact:
      ORACLE_HOMES_DIR: "/u01/app/oracle/product"
      DB_HOME: "{{ ORACLE_HOMES_DIR }}/{{ ORACLE_VERSION }}/dbinst_1"

  - name: Copy script to host
    copy:
      src: "{{ playbook_dir }}/{{ script_name }}"
      dest: "/tmp/"
      owner: "{{ USER_ORACLE }}"
      group: "{{ GROUP_ORACLE }}"
      mode: 0755

  - name: Verify if the DB is open READ WRITE (or) not
    become_user: "{{ USER_ORACLE }}"
    environment:
      ORACLE_SID: "{{ sid }}"
      ORACLE_HOME: "{{ ORACLE_HOME }}"
    shell: "echo \"set pagesize 0\n select trim(open_mode) from v\\$database;\" | {{ORACLE_HOME}}/bin/sqlplus -S / as sysdba"
    with_items: "{{ hostvars[inventory_hostname]['sid_list'] }}"
    loop_control:
      loop_var: sid
    register: om

  - name: Get the OM output
    debug:
     msg: "om Results {{ item.0.sid }} is {{ item.1.value }}"
    with_dict: "{{ om.results }}"
    when: ("'sid' in item.key" and "'stdout' in item.key")

I am trying to print all the value for keys "sid" & "stdout" here, below is the dictionary output. So i can use loop condition to loop through running SQL queries for all SID's which are in "READ WRITE" mode.

As best I can tell, you're looking for the sid whose om.results[].stdout contains READ WRITE ? If so, with_dict: is for sure the wrong way to go about that since om.results is a list not a dict ; what you want is:

- debug:
    msg: read write SIDs are {{ rw_sid_list }}
  vars:
    rw_sid_list: '{{ om.results
      | selectattr("stdout", "eq", "READ WRITE")
      | map(attribute="sid")
      | list }}'
