boot.settings module

class boot.settings.SettingConfig(source: Config | dict[str, Any], dict_prefix: str = '')

基类：Config

Configurables in django framework w.r.t the project.

For example, login url is not configurable and should be hard-coded.

db_host = 'mysql'

db_name = 'yppf'

db_password = 'secret'

db_port

延迟加载的配置项

在Config类中作为属性定义，如:

class AppConfig(Config):
    # 由语言服务器自动推断类型
    value = LazySetting('value', default=0)
    op1 = LazySetting('op1', int)
    op2 = LazySetting('op2', int, default=0)
    # 也可以使用type指定类型，写法建议参考`LazySetting.checkable_type`的文档
    assert_d = LazySetting('value/dict', type=dict)
    i_or_s = LazySetting('value/i_or_s', type=(int, str))
    assert_ls = LazySetting('value/ls', type=list[str])
    tuple = LazySetting('value/tuple', type=tuple[int, str])

上述代码在访问时会自动计算并缓存结果:

config = AppConfig()
# 自动推断的类型
config.value: int
config.op1: int | None
config.op2: int
# 用type指定的类型
config.assert_d: dict
config.i_or_s: int | str    # 检查是否为int或str
list[str], tuple[int, str]  # 检查是否为列表，元组等，不检查元素类型

抛出:

ImproperlyConfigured -- 配置最终值不匹配期望类型

db_user = 'root'

secret_key = 'k+8az5x&aq_!*@%v17(ptpeo@gp2$u-uc30^fze3u_+rqhb#@9'

static_dir = '/workspace'
