Python jinja2 indentention和whitespace问题

Question

我有以下jinja2模板。当我渲染它时，“endif”语句后面的行没有适当的缩进。我试过传递trim_blocks = True和keep_trailing_newline = False没有太大成功。

   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。 部门和付费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。 部门和付费与付费，版本等对齐。

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

我想知道还有什么我可以错过。

谢谢，

Answer 1

-%}将占用括号后的所有空格（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"

Answer 2

这是我如何最终解决它：

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