formex v0.5.3 Formex.Validator behaviour
Validator behaviour.
In Formex you can use any validation library. Of course, if proper adapter is already implemented.
Available adapters:
Installation
Setting default validator:
config/config.exs
config :formex,
validator: Formex.Validator.Vex
Using another validator in a specific form type
def build_form(form) do
form
|> add(:name, :text_input)
# ...
end
def validator, do: Formex.Validator.Vex
If you want to translate errors messages, set a translation function in config:
config :formex,
translate_error: &App.ErrorHelpers.translate_error/1
The &App.ErrorHelpers.translate_error/1
is a function generated by Phoenix in
/web/views/error_helpers.ex
. You can also set your own similar function.
Implementing adapter for another library
See implementation for Vex for example.
