Description
This PR adds a new
ConfigureContextparameter toFluentValidationValidator. This parameter allows users to pass anActionto modify theValidationContextbefore it is passed to FluentValidation validators.This solves the issue in #183, also addressed in #156, but instead of just allowing you to set RootContextData, it provides more robust access to ValidationContext configuration.
Why is this needed?
Currently, Blazored.FluentValidation does not provide a way to customize the
ValidationContextused when validating a model. FluentValidation provides powerful context features, that Blazor users could make use of.Why is this better than just allowing
RootContextData?RootContextDatais static per validation execution, whileConfigureContextallows for dynamic modifications.ValidationContext<T>contains more than justRootContextData—it also allows setting a custom selector or defining a property chain.RootContextDataalone would be insufficient.Example Usage
This ensures that validators can access
UserRoledynamically during validation.Unit tests of this feature are also included in the PR.
