AutoSelect2Tag

Provide tag-helper methods for create Select2 elements by the same way as any other view elements.

Firstly install AutoSelect2 with dependency. Then add this line to your application's Gemfile:

gem 'auto_select2_tag'

And execute:

$ bundle

You can find example project here.

Gem provide only two helper methods for initialize select2 elements:

• select2_tag
• select2_ajax_tag

details about realization you can find on AutoSelect2 page.

select2_tag(name, option_tags = nil, options = {})

Has same behavior as common select_tag. In addition you can specify :select2_options in options. This parameter allow to set select2 constructor options.

= select2_tag :select2_name,
               my_options_for_select2(my_init_value),
               placeholder: 'Fill me!',
               include_blank: true,
               select2_options: {width: 'auto'}

select2_ajax_tag(name, select2_searcher, value = nil, options = {})

All allowed options for this helper can be found on AutoSelect2 page. look at example below; this is an easy way to understand helper parameters.

If you define SearchAdapter named MySearchAdapterName, you can use the follow code:

= select2_ajax_tag :my_select2_name,
                   :my_search_adapter_name,
                   my_init_value_id,
                   placeholder: 'Fill me now!',
                   search_method: :unusual_case,
                   class: 'my-select2-input',
                   select2_options: {additional_ajax_data: {selector: '.additional-elements'}}

If you want lightweight selection over columns of ActiveRecord model:

= select2_ajax_tag :my_select2_name,
                   {class_name: :your_model_name, text_column: :name, id_column: :id},
                   my_init_value_id,
                   placeholder: 'Fill me now!'

In this case you get select2 selent with search by name column over model YourModelName.
