Question

How I can add checkbox with simple_form without association with model? I want to create checkbox which will handle some javascript events, but don\'t know? Maybe I miss som

Answer 1

Add this to app/inputs/arbitrary_boolean_input.rb:

class ArbitraryBooleanInput < SimpleForm::Inputs::BooleanInput
  def input(wrapper_options = nil)
    tag_name = "#{@builder.object_name}[#{attribute_name}]"
    template.check_box_tag(tag_name, options['value'] || 1, options['checked'], options)
  end
end

then use it in your views like:

= simple_form_for(@some_object, remote: true, method: :put) do |f|
  = f.simple_fields_for @some_object.some_nested_object do |nested_f|
    = nested_f.input :some_param, as: :arbitrary_boolean

i.e. The above implementation supports nested fields correctly. Other solutions I've seen do not.

Note: This example is HAML.
