How to insert html attributes with "-" sign into text_field_tag?

Question

Ruby on Rails

I am making a range slider as a filter using bootstrap-slider, I don’t know how to insert values ​​with a "-" sign into text_field_tag, I need to insert the following

data-slider-min="10" data-slider-max="1000" data-slider-step="5" data-slider-value="[250,450]"

made the following form

<%= form_tag @sub_category, method: 'get' do |d| %>
<%= text_field_tag "ex2", type: "text", class: "span2" %>
<% end %>

here in

<%= text_field_tag "ex2", type: "text", class: "span2" %>

must be inserted

data-slider-min="10" data-slider-max="1000" data-slider-step="5" data-slider-value="[250,450]"

insert

%= text_field_tag "ex2", type: "text", class: "span2",data: {'slider-id' => 'ex2',
                        'slider-min' => '0',
                        'slider-max' => '20',
                        'slider-step' => '1',
                        'slider-value' => '[250,450]' } %>

displays

:data=>{"slider-id"=>"ex2", "slider-min"=>"0", "slider-max"=>"20", "slider-step"=>"1", "slider-value"=>"[250,450]"}}"

but something doesn't work.
And tell me how best to filter the output after submitting the form with range slider?

Answer 1

= text_field_tag "prop[one]", nil, data: { slider-min: min, slider-max: max, slider-step: step, slider-value: value }, class: 'span2'

<input readonly="" class="span2" data-slider-max="5000" data-slider-min="800" data-slider-step="10" data-slider-value="250,450" id="" name="prop[one]" type="text">

Answer 2

Apparently, text_field_tag ​​does not have special processing of the data parameter (which link_to and form_for have), and you need to write 'data-slider-min' => '0' yourself.
Advice in such cases, when something is not clear where it comes from - take it and do it without builders and other goodies: take it and stupidly write simple html. And how it works - then already figure out why it doesn’t work out beautifully.
