Simple validator DSL / library for F#
License: MIT License
Currently if a nested validator (created using withValidator
or eachItemWith
, etc... fires - it only reports the property name as it knows it so for some object like
{
a: {
Id: ""
b: {
Id: ""
c: {
Id: ""
}
}
}
it will report Id is empty
(or equivalent), so for complex objects it is difficult to figure out that it was a.b.c.Id
that was empty and not some other one.
What would be a good way to fix this?
Chessie.ErrorHandling provides effectively the same format as your ValidationState but comes with a large number of helpers that can be used to manipulate the Error list.
This differs from the Framework version in that is also has a list of Errors (as well as handling Warn situations too).
Find it here: https://github.com/fsprojects/Chessie
N.B. this was Steffan Forkman and goes with the Railway Oriented Programming topics covered here: https://fsharpforfunandprofit.com/rop/ (Scott Wlaschin) both of which you must have come across.
I'm happy enough to submit a pull request if you like. I'd just use a type for the ValidationState and any helpers from Chessie where appropriate.
Hey @JamesRandall , I'm giving this project a try and was wondering how you would tackle an async validation.
I wish to check if my string is an existing user in my case.
Any ideas?
