棱柱形/模式需要关键依赖？

Question

我正在使用plumatic/schema 和我的compojure-api 来验证端点的输入。

我的架构中有两个键：Field1 和 Field2。我希望能够为我的架构定义一个规则，例如：

WHEN Field1 = "AA" 
THEN Field2 is required-key 
ELSE Field2 is optional-key

但是，我似乎只能将密钥设置为必需或可选。是否可以使一个键依赖于另一个键？

(schema/def Field1
  (schema/enum "AA" "BB"))

(schema/def Field2
  (schema/enum "AAAA" "BBBB" "CCCC"))


(schema/defschema MySchema
  {(schema/required-key :field1)           Field1
   
   ; Here I want some kind of logic to make the key required if 
   (if (= Field1 "AA")
       (schema/required-key :field2)      Field2
       (schema/optional-key :field)      Field2)
   })

Answer 1

(use '[plumbing.core])

(schema/defschema MySchema
    (schema/conditional
        (fn-> :field1 (= "AA"))
        (schema/schema-with-name {(schema/required-key :field1) Field1
                                  (schema/required-key :field2) Field2} "cond1")
        
        :else
        (schema/schema-with-name {(schema/required-key :field1) Field1
                                        (schema/optional-key :field2) Field2} "cond2")))
