From 970ee6448dde0aed55aa2d61522504df78a9e835 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Antoine=20Vandecr=C3=A8me?= Date: Wed, 1 Feb 2023 16:19:02 +0100 Subject: [PATCH] Make items objects instead of arrays for tuples Workaround for https://github.com/biocad/openapi3/issues/31 If the tuples has homogeneous types, the generated schema is strict. On the other hand if there are heterogeneous types, the schema is not very strict because the order in which the types must come is not specified. Also, I had to use anyOf instead of oneOf because for example the int in (Int, Float) matches both Integer and Number. Finally, special care had to be taken to handle nullables. --- src/Data/OpenApi/Internal/Schema.hs | 149 ++++++++++++--------- test/Data/OpenApi/CommonTestTypes.hs | 83 +++++++++++- test/Data/OpenApi/Schema/GeneratorSpec.hs | 10 +- test/Data/OpenApi/Schema/ValidationSpec.hs | 4 +- test/Data/OpenApi/SchemaSpec.hs | 5 +- 5 files changed, 175 insertions(+), 76 deletions(-) diff --git a/src/Data/OpenApi/Internal/Schema.hs b/src/Data/OpenApi/Internal/Schema.hs index 1f886bd7..70a76cb7 100644 --- a/src/Data/OpenApi/Internal/Schema.hs +++ b/src/Data/OpenApi/Internal/Schema.hs @@ -5,6 +5,7 @@ {-# LANGUAGE FlexibleContexts #-} {-# LANGUAGE FlexibleInstances #-} {-# LANGUAGE KindSignatures #-} +{-# LANGUAGE LambdaCase #-} {-# LANGUAGE OverloadedLists #-} {-# LANGUAGE OverloadedStrings #-} {-# LANGUAGE PackageImports #-} @@ -24,7 +25,7 @@ module Data.OpenApi.Internal.Schema where import Prelude () import Prelude.Compat -import Control.Lens hiding (allOf) +import Control.Lens hiding (allOf, anyOf) import Data.Data.Lens (template) import Control.Monad @@ -356,14 +357,16 @@ inlineNonRecursiveSchemas defs = inlineSchemasWhen nonRecursive defs -- "Jack", -- 25 -- ], --- "items": [ --- { --- "type": "string" --- }, --- { --- "type": "number" --- } --- ], +-- "items": { +-- "anyOf": [ +-- { +-- "type": "string" +-- }, +-- { +-- "type": "number" +-- } +-- ] +-- } -- "type": "array" -- } -- @@ -404,7 +407,7 @@ sketchSchema = sketch . toJSON & type_ ?~ OpenApiArray & items ?~ case ischema of Just s -> OpenApiItemsObject (Inline s) - _ -> OpenApiItemsArray (map Inline ys) + _ -> OpenApiItemsObject (Inline $ mempty & anyOf ?~ (map Inline ys)) where ys = map go (V.toList xs) allSame = and ((zipWith (==)) ys (tail ys)) @@ -440,35 +443,37 @@ sketchSchema = sketch . toJSON -- 3 -- ] -- ], --- "items": [ --- { --- "enum": [ --- 1 --- ], --- "maximum": 1, --- "minimum": 1, --- "multipleOf": 1, --- "type": "number" --- }, --- { --- "enum": [ --- 2 --- ], --- "maximum": 2, --- "minimum": 2, --- "multipleOf": 2, --- "type": "number" --- }, --- { --- "enum": [ --- 3 --- ], --- "maximum": 3, --- "minimum": 3, --- "multipleOf": 3, --- "type": "number" --- } --- ], +-- "items": { +-- "anyOf": [ +-- { +-- "enum": [ +-- 1 +-- ], +-- "maximum": 1, +-- "minimum": 1, +-- "multipleOf": 1, +-- "type": "number" +-- }, +-- { +-- "enum": [ +-- 2 +-- ], +-- "maximum": 2, +-- "minimum": 2, +-- "multipleOf": 2, +-- "type": "number" +-- }, +-- { +-- "enum": [ +-- 3 +-- ], +-- "maximum": 3, +-- "minimum": 3, +-- "multipleOf": 3, +-- "type": "number" +-- } +-- ] +-- }, -- "maxItems": 3, -- "minItems": 3, -- "type": "array", @@ -483,26 +488,28 @@ sketchSchema = sketch . toJSON -- 25 -- ] -- ], --- "items": [ --- { --- "enum": [ --- "Jack" --- ], --- "maxLength": 4, --- "minLength": 4, --- "pattern": "Jack", --- "type": "string" --- }, --- { --- "enum": [ --- 25 --- ], --- "maximum": 25, --- "minimum": 25, --- "multipleOf": 25, --- "type": "number" --- } --- ], +-- "items": { +-- "anyOf": [ +-- { +-- "enum": [ +-- "Jack" +-- ], +-- "maxLength": 4, +-- "minLength": 4, +-- "pattern": "Jack", +-- "type": "string" +-- }, +-- { +-- "enum": [ +-- 25 +-- ], +-- "maximum": 25, +-- "minimum": 25, +-- "multipleOf": 25, +-- "type": "number" +-- } +-- ] +-- }, -- "maxItems": 2, -- "minItems": 2, -- "type": "array", @@ -982,10 +989,22 @@ gdeclareSchemaRef opts proxy = do return $ Ref (Reference name) _ -> Inline <$> gdeclareSchema opts proxy -appendItem :: Referenced Schema -> Maybe OpenApiItems -> Maybe OpenApiItems -appendItem x Nothing = Just (OpenApiItemsArray [x]) -appendItem x (Just (OpenApiItemsArray xs)) = Just (OpenApiItemsArray (xs ++ [x])) -appendItem _ _ = error "GToSchema.appendItem: cannot append to OpenApiItemsObject" +addItem :: (Referenced Schema -> [Referenced Schema] -> [Referenced Schema]) + -> Referenced Schema + -> Maybe OpenApiItems + -> Maybe OpenApiItems +addItem _ x Nothing = Just (OpenApiItemsArray [x]) +addItem add x (Just (OpenApiItemsArray xs)) = case xs of + [] -> Just $ OpenApiItemsObject x + [x'] | x == x' -> Just $ OpenApiItemsObject x + _ | x `elem` xs -> Just $ OpenApiItemsObject $ Inline $ mempty & anyOf ?~ xs + _ -> Just $ OpenApiItemsObject $ Inline $ mempty & anyOf ?~ (add x xs) +addItem add x (Just (OpenApiItemsObject (Inline s))) = + let appendMaybe = Just . maybe [x] (\xs -> if x `elem` xs then xs else add x xs) + in Just $ OpenApiItemsObject $ Inline $ s & anyOf %~ appendMaybe +addItem add x j@(Just (OpenApiItemsObject ref)) + | x == ref = j + | otherwise = Just $ OpenApiItemsObject $ Inline $ mempty & anyOf ?~ (add x [ref]) withFieldSchema :: forall proxy s f.
