Set Default Classes For Submit Button In Simple Form

Question

I'm using Simple Form with Rails 3.2. I'm currently adding the same classes to the submit button of each form within my app. There are a lot of forms so this isn't very DRY.

<%= f.button :submit, class: "form-submit" %>

Is there a way to configure Simple Form to use a default class for all submit buttons?

Answer 1

Actually it is possible to add default class to button in simple form. In config/initializers/simple_form.rb:

SimpleForm.setup do |config|
  # Default class for buttons
  config.button_class = 'btn form-submit'
end

Tested in Simple Form 3.0.1 Remember to restart server after making changes to files in initializers directory.
