Rails传递布尔值false至JSON Schema时的验证异常问题

问题现象 #

• 使用activerecord_json_validator进行JSON Schema验证时，布尔值true可正常通过验证，但false会被判定为缺失必填项
• 启用模型验证规则validates :column, inclusion: {in: [true, false] }后，传递false会触发报错：Validation failed: value1 is not included in the list, value2 is not included in the list
• 控制台直接赋值false测试同样失败，错误提示：["Dynamic attributes object at root is missing required properties: bladder_compatible, bladder_included"]

环境与背景 #

• 应用通过activerecord_json_validator读取CSV文件数据并做JSON Schema验证，CSV中的布尔值以字符串"true"/"false"形式传递，已实现类型转换逻辑
• 当前使用的布尔值转换方法：

def convert_to_bool(value)
  return true if value == true || value.to_s.downcase == 'true'
  return false if value == false || value.to_s.downcase == 'false'

  value
end

• 日志显示转换逻辑已成功将字符串"true"/"false"转为布尔值true/false，但JSON Schema验证仍提示缺少必填项
• 使用的JSON Schema定义：

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "type": "object",
  "properties": {
    "bladder_compatible": {
      "type": "boolean"
    },
    "bladder_included": {
      "type": "boolean"
    },
    "bladder_volume_l": {
      "type": "number",
      "minimum": 1.5,
      "maximum": 3
    }
  },
  "required": ["bladder_compatible", "bladder_included"]
}

• 该Schema在其他验证器及activerecord_json_validator依赖的json schemer中测试均正常

控制台测试代码 #

b = BagContainer.new
b.dynamic_attributes = {bladder_compatible: false, bladder_included: false, bladder_volume_l: 2}
b.valid?
# 验证失败，执行b.errors.full_messages返回：
# ["Dynamic attributes object at root is missing required properties: bladder_compatible, bladder_included"]
