How to convert this Component to SimpleForms 3.1.0.rc1?

[John McDowall]

Hi Folks, 

I'm trying to upgrade a SimpleForm 2 custom component that looked like this:

module Dresssed

  module SimpleForm

    # Custom SimpleForm component to add a 'Required' tag next to required inputs when

    # there are no errors.

    class RequiredComponent < ComponentBase

      def required_field?

        @input.send(:required_field?)

      end

      def render

        required_tag if required_field? && !@input.has_errors?

      end

      def required_tag

        template.content_tag :div,

                             template.icon_tag("asterisk") + " " + translate_required_text,

                             :class => "help-inline"

      end

      def translate_required_text

        I18n.t(:"simple_form.required.text", :default => 'required')

      end

    end

  end

end

And used to be able to be set like this in the initializer:

    ba.use Dresssed::SimpleForm::RequiredComponent

As far as a I can see, ComponentBase is completely gone in 3.1.0.rc1? 

Any suggestions as to how I should re-implement this component?

Thanks!

A component just need to respond to the same method you are defining in the wrapper API. For example the hint component define a method called hint. For you case you would need to define a required method that does what you want it to do. There is no need for base classes anymore.

BTW, I don’t believe we ever had a ComponentBase class.

Wow, that is a lot simpler - thanks for the heads up. 

Yes sorry, turns out that ComponentBase existed in a legacy project I’ve just taken over. 

Thanks!
