Question

如何遍历字典和文件树？我想将带有.j2后缀（关键字）的模板文件递归到目标位置（值），还应该重命名基本名称（删除.j2后缀）。它是一个完美的用例。不幸的是，ansible不适用于复杂的数据结构。

输入：

public GameObject scoretext;
public GameObject itemlefttext;
public GameObject finalScore;
public static float score = 0;

public GameObject winPanel;

private void Start()
{
    scoretext.GetComponent<Text>().text = "0";
    setscore(0);
}

private void Update()
{
    itemlefttext.GetComponent<Text>().text = "" + GameObject.FindGameObjectsWithTag("draggableobject").Length;

    if (GameObject.FindGameObjectsWithTag("draggableobject").Length == 0)
    {
        winPanel.SetActive(true);
    }
}

public void setscore(float scoretoadd)
{
    score += scoretoadd;
    scoretext.GetComponent<Text>().text = score.ToString("F0");
    finalScore.GetComponent<Text>().text = score.ToString("F0");
}

我的尝试：

{% for brand in brands %}
    {% if brand.product %}
        <!-- Displays brand -->
    {% endif %}
{% endfor %}

我知道在游戏中使用jinja不好，如果可能的话，我想避免使用它。另外，输入数据结构也不应更改。

感谢

如果我了解您要执行的操作，那么我认为有一个相当简单的解决方案。如果您编写一个名为template_files.yml的任务文件：

---
- name: render templates to dest_dir
  loop: "{{ query('filetree', src_dir) }}"

  # we need this to avoid conflicts with the "item" variable in
  # the calling playbook.
  loop_control:
    loop_var: template
  when: template.src.endswith('.j2')
  template:
    src: "{{ template.src }}"
    dest: "{{ dest_dir }}/{{ (template.src|basename)[:-3] }}"

然后您可以编写这样的剧本：

---
- hosts: localhost
  gather_facts: false
  vars:
    applications:
      application1:
        svcpaths:
          localfolder/bardir1: /tmp/remotefolder/bardir1
          localfolder/bardir2: /tmp/remotefolder/bardir2
          localfolder/bardir3: /tmp/remotefolder/bardir3
      application2:
        svcpaths:
          localfolder/bardir5: /tmp/remotefolder/bardir5
          localfolder/bardir6: /tmp/remotefolder/bardir6

  tasks:
    # generate a list of {key: src, value: destination} 
    # dictionaries from your data structure.
    - set_fact:
        templates: "{{ templates|default([]) + item|dict2items }}"
      loop: "{{ applications|json_query('*.svcpaths')}}"

    # show what the generated variable looks like
    - debug:
        var: templates

    # template all the things
    - include_tasks: template_files.yml
      loop: "{{ templates }}"
      vars:
        src_dir: "{{ item.key }}"
        dest_dir: "{{ item.value }}"

鉴于我有一组本地文件，如下所示：

localfolder/bardir1/example.txt.j2
localfolder/bardir2/example.txt.j2
localfolder/bardir3/example.txt.j2
localfolder/bardir5/example.txt.j2
localfolder/bardir6/example.txt.j2

运行剧本会导致：

/tmp/remotefolder/bardir6/example.txt
/tmp/remotefolder/bardir5/example.txt
/tmp/remotefolder/bardir3/example.txt
/tmp/remotefolder/bardir2/example.txt
/tmp/remotefolder/bardir1/example.txt

我认为这可能比您正在使用的基于Jinja模板的解决方案更易于阅读和理解。
