Python jinja2 缩进和空格问题

Question

我有以下 jinja2 模板。当我渲染它时，“endif”语句之后的行没有适当的缩进。我试过通过 trim_blocks=True 和 keep_trailing_newline=False 没有太大的成功。

   applications:
      {{ application_name }}:
        version: {{ version }}
        {% if dependencies is not none: -%}
        dependencies:
          {% for key, value in dependencies.items() -%}
            - {{ key }}: {{ value }}
          {% endfor -%}
        {% endif -%}
        {% if departments is not none: -%}
        departments:
          {% for key, value in departments.items() -%}
            - {{ key }}: {{ value }}
          {% endfor -%}
        {% endif -%}
        paid: "yes"
        obsolete: "no"

实际结果。 departments 和 paid 块不遵循数据结构层次结构

applications:
  appication1:
    version: "1.0"
    dependencies:
      - database: mysql
      - storage: nfs
      departments: <- Indent is not correct
      - accounting: payroll
      paid: "yes" <- Indent is not correct
    obsolete: "no"

预期结果。 departments 和 paid 与 paid、version 等保持一致。

applications:
  appication1:
    version: "1.0"
    dependencies:
      - database: mysql
      - storage: nfs
    departments:
      - accounting: payroll
    paid: "yes"
    obsolete: "no"

我想知道我还缺少什么。

谢谢，

Answer 1

这就是我最终解决它的方法：

{%- if environment is not none: %}
enviroment:
{%- for key, value in environment.items() %}
  - {{ key }}: {{ value }}
{%- endfor -%}
{%- endif %}

Answer 2

-%} 将吃掉该括号之后 之后的所有空格（包括换行符）。我认为您可能希望在左括号 ({%-) 上使用 -：

   applications:
      {{ application_name }}:
        version: {{ version }}
        {% if dependencies is not none: -%}
        dependencies:
          {% for key, value in dependencies.items() -%}
            - {{ key }}: {{ value }}
          {% endfor -%}
        {% endif -%}
        {%- if departments is not none: %}
        departments:
          {% for key, value in departments.items() -%}
            - {{ key }}: {{ value }}
          {% endfor -%}
        {%- endif %}
        paid: "yes"
        obsolete: "no"
