Dependent Questions

Dependent questions are questions that should be presented only if another question is answered with a trueful answer.

For example, consider the following cookiecutter.json:

{
    "is_storage": true,
    "access_mode?{{cookiecutter.is_storage}}": ["ReadWriteOnce", "ReadOnlyMany", "ReadWriteMany"],
    "app": "app"
}

The second question access_mode will be asked just if the value of is_storage is True, otherwise the default value ("ReadWriteOnce") will be stored in access_mode.

Question prompt

• Setting is_storage to True:

  is_storage [True]: true
  Select access_mode:
  1 - ReadWriteOnce
  2 - ReadOnlyMany
  3 - ReadWriteMany
  Choose from 1, 2, 3 [1]: 2
  app [app]: application
  

• Setting is_storage to False:

  is_storage [True]: false
  app [app]: application
  

Support any boolean expression

Any boolean expression is supported after a ? character.

For example:

{
  "queue": ["kafka", "rabbit"],
  "topic?{{cookiecutter.queue=='kafka'}}": "topic",
  "app": "app"
}

The expression will be evaluated as a Jinja2’s boolean expression.

Template use

These example values can be used in a template, such as the following:

{%- if cookiecutter.is_storage -%}
access_mode = {{cookiecutter.access_mode}}
{% endif %}
