We disabled remote forms when using form_with because things like flash
messages don't show up when we re-render. Maybe we can come up with a way of
adding a layout/application.js.haml to insert flashes into the page
dynamically. We'll want to remove the following configuration:
Rails.application.config.action_view.form_with_generates_remote_forms = falseRight now HTML5 validation has different messages on each browser. Ideally we
would show the same validation messages that come up when validating
ActiveRecord models. We should build a tool that uses setCustomValidity to
customize the message to match what appears on the server. This would also help
us to test validations in system tests against both Rack::Test, Chrome, and
Firefox.
Rack::Test does not implement HTML5 validation, so when submitting a form it
relies on server-side validation and the followup error messages when it
re-renders the form. Browsers, on the other hand, implement HTML5 validation,
so when testing against Firefox or Chrome, it prevents submitting the form in
the first place. When asserting against error messages in system tests, we
should have a tool that takes into account which driver is being used and
search for the error either in an errors div in the case of Rack::Test or for
JS enabled browsers we should be able to use:
page.find("#field_id").native.attribute("validationMessage")This depends on the error messages being the same both in HTML5 validations and in server rendered errors.
