Taiwan Bank Code

The gem provide a Rails engine for easily integrating (Taiwanese) banks and their codes as a dropdown select.

Add this line to your application's Gemfile:

gem 'taiwan_bank_code'

And then execute:

$ bundle

Or install it yourself as:

$ gem install taiwan_bank_code

The foundamental way.

form_with(sth) do |f|
  f.bank_select(:bank, {}, {})
end
# => <select name="sth[bank]"><option value=""></option>
# <option value="004 臺灣銀行">004 臺灣銀行</option>
# <option value="005 臺灣土地銀行">005 臺灣土地銀行</option>
# ...

One is able to customize the name-value pair in the options by a following block. For example:

form_with(sth) do |f|
  f.bank_select(:bank, {}, {}) {|bank| [bank["name"], bank["code"]]}
end
# => <select name="sth[bank]"><option value=""></option>
# <option value="004">臺灣銀行</option>
# <option value="005">臺灣土地銀行</option>
# ...

where the data structure is:

[
  {"name": "xxx", "code": 999},
  # ...
]

Right now the gem is hardly completed, but the author(s) has no plan to develop this in the near future. Any contribution is welcomed. The most urgent feature is to patch the main function to select_tag(ActionView::Helpers::FormTagHelper) and re-realize the current function select by calling the preceding method.
