View Source Ash.Resource.Validation behaviour (ash v3.4.44)
Represents a validation in Ash.
See Ash.Resource.Validation.Builtins
for a list of builtin validations.
To write your own validation, define a module that implements the init/1
callback
to validate options at compile time, and validate/3
callback to do the validation.
Then, in a resource, you can say:
validations do
validate {MyValidation, [foo: :bar]}
end
