ruby-on-rails - Simple_form 自定义输入

Question

我有这行代码：

= f.input :goal, as: :select, input_html: {class: "select2"}, wrapper_html: {class: "form-fields"}

我想求助

= f.input :goal, as: :select2

在 simple_form 中使用自定义输入。我如何实现这一目标？到目前为止，我有：

class Select2Input < SimpleForm::Inputs::StringInput
  def input
    input_html_options[:class]<< 'select2'
  end
end

Answer 1

This should get you half-way there:

class Select2Input < SimpleForm::Inputs::CollectionSelectInput
end

and

<%= f.input :email, as: :select2, wrapper_html:{class: "form-fields"} %>

You may have to create a custom wrapper for the select2 input in config/initializers/simple_form.rb to be able to use it in the way you really want.

Answer 2

这些可能会有所帮助，尽管我对简单的形式不是很熟悉。
