Rails: Attribute required for collection in simple_form

问题

We are trying to set required in simple_form. The following setup does not work.

<%= f.input :payee_id, :label => t('Payee'), required: true, :collection => BankAccountx.payee_class.where(active: true).map {|x| [x.name, x.id]}, :selected => params[:payee_id], include_blank: true %>

Also tried :input_html => {required: true} and it did not work as well.

What's the right way to set required in simple_form?

回答1:

Found it. If you use this command:

rails generate simple_form:install

It will create a file at config/initializer/simple_form.rb. Find this line

config.browser_validations = false

And change it to true. NOTE: If you just add the gem and not run rails generate, it works by default.
