Check if a key present in map

[nirupbbnk]

properties:
caseID:
type: string
description: some description
detailed_goal:
type: string
description: some description for goal
context:
type: string
description: some description for context

This is my data , here i want to validate if map has key context , we want to check only if context is present , rest keys are dynamic and may change,
We want to validate only context key is present , rest keys can be anything,

properties: map(key=regex('context'))

Currently I am using this , but validation fails as it has other keys , (as other keys are dynamic we can't have static value )

Quite an old issue, but I believe this will do what you want:

Schema:

properties: include('props', required=True, strict=False)
---
props:
    context: include('cont', required=True)     
---
cont:
    type: str()
    description: str()    

This assumes your data is on the following form:

properties:
    context:
        type: string
        description: A string value
    other_key:
        type: string
        description: A string value
