无法将属性与数字进行比较.错误:“在'AnsibleUnsafeText'和'int'的实例之间不支持"； [英] Can't compare attribute to a number. Error: "not supported between instances of 'AnsibleUnsafeText' and 'int'"

问题描述

- getent:
    database: passwd
- debug: 
    var: getent_passwd | dict2items | selectattr('value.1', '>=', 1000) | map(attribute='key') | list

输出为

TASK [debug] ******************************************************************************************************
fatal: [localhost]: FAILED! => {"msg": "Unexpected templating type error occurred on 
({{getent_passwd | dict2items | selectattr('value.1', '>=', 1000) | map(attribute='key') | list}}): 
'>=' not supported between instances of 'AnsibleUnsafeText' and 'int'"}

如何将"value.1"更改为整数?

How can I change 'value.1' to integer?

推荐答案

Q:" 如何将 value.1 更改为整数?";

A:使用 json_query 函数 to_number .例如

    - debug:
        var: getent_passwd|
             dict2items|
             json_query('[?to_number(value[1]) >= `1000`].key')

Q:" 如何将 1000 更改为变量?"

A:替换也应转换为数字.最好单独声明 query .例如

A: The substitution should be converted to a number too. It's a good idea to declare the query separately. For example

    - set_fact:
        myusers: "{{ getent_passwd|dict2items|json_query(query) }}"
      vars:
        myuid: 1000
        query: "[?to_number(value[1]) >= to_number('{{ myuid }}')].key"

---

Q:" 如何向json_query函数添加更多条件?像 selectattr('value.5'，'ne'，'/sbin/nologin').'

A:使用管道或给予

    "myusers": [
        {
            "user": "libvirt-qemu", 
            "shell": "/usr/sbin/nologin", 
            "uid": "64055"
        }, 
        {
            "user": "nobody", 
            "shell": "/usr/sbin/nologin", 
            "uid": "65534"
        }
    ]

根据需要调整变量和比较运算符.

json_query中的管道可能被认为是反模式.因此，应该使用和表达式代替管道.例如

The pipe in json_query might be considered an anti-pattern. Therefore and-expression should be used instead of the pipe. For example

  query: "[?(to_number(value[1]) >= to_number('{{ myuid }}')) &&
            (value[5] == '{{ myshell }}')].{user: key, uid: value[1], shell: value[5]}"
