Python jinja2注意和空白問題

Question

我有以下jinja2模板。當我渲染它時，「endif」語句後面的行沒有正確的縮進。我試過傳遞trim_blocks = True和keep_trailing_newline = False沒有太大的成功。

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" 

實際結果。 部門和支付塊不按照數據的結構層次

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" 

預期結果。 部門和支付對齊與支付，版本等

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

我想知道我可能會錯過什麼。

感謝，

Answer 1

這怎麼我終於解決了這個問題：

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

Answer 2

的-%}會吃掉畢竟空白那架（包括新行）。我認爲你可能會想在開幕支架（{%-）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"
