For an example, generate an odd number between 10-20:
{
"type": "integer",
"minimum": 10,
"allOf": [
{
"maximum": 20
}
],
"not": {
"allOf": [
{
"multipleOf": 2
}
]
}
}
The example provided is deliberately more complex than it needs to be to show the composing nature of the problem.

Do you have a proposed solution for this?

It seems like the original author built a new schema and "manually" inversed some of the properties and then replaced the original schema...
For an example, it does not handle multipleOf
that I mentioned originally.
I suppose that was meant to be handled in the TODO section lower in the linked method, but I do not think that it is possible for multipleOf
since that should be evaluated in the value generator itself since there is no way to "inverse" it (if I am not mistaken?).
Another approach might be to collect all the constraints imposed on a certain value and then generate a value matching all those constraints?
For an example:
type
must beinteger
- value must be in range 10 .. 20
- must not be divisible by 2
But I assume that could get very complicated very fast with lots of constraints...

I think that the problem is much bigger than I initially assumed:

The current implementation will only take type
into consideration if it encounters that keyword, so valid definitions such as the one below will not work:
{
"type": "integer",
"allOf": [
{
"minimum": 10
},
{
"maximum": 20
}
]
}
The above should be equivalent to:
{
"type": "integer",
"minimum": 10,
"maximum": 20
}
I think the __parse_definition
needs to do some more sofisticated "merging" than it currently does. Unfortunately, I do not know Python to jump in with any PRs...
from jsf.
I would have thought the above wouldn't be valid without a type in the all of objects.
from jsf.
Yup, that was my assumption also at first, but things are a bit more complicated...
I have tested the schema above with the original JSF and here. Seems to be valid.
