ruby on rails - set data-* attribute -

I have a situation where I have to set the price for a "data- *" on a div in a dual way What I'm really using is:

  = tag ('div', {class: 'agile-carousel', data: {carousel_list: url_for (format :: json)} }, True) = "& lt; / div & gt;" Html_safe   
 Which is awesome, besides rail one  and lt; Div / & gt;  Turns off the device in a fashion, which certainly does not like Chrome and other browsers (to create some disasters).  
 So my solution is that one. I would like to ask that there is another way to do this.  
  Update 1:   
 I have a small problem, this code:  
  Span class == I18n.locale == locale_used? "Disabled": zero = link_ to (I18n.t ('locale_name', locale: locale_used), \ url_ (locale: locale_US))   
 If I remove link_to this job Does. Note that if i  | << Code>   "<< P>   instead of  
      >  content_tag  instead of> tags > 
 , but you should not  
 you are using Therefore, the use of  slim :  
  .gile-carouesel data-carousel_list = Url_for (format :: json) < / Code>  
 Output:  
  
  
 The whole point of Slim and Ham is that you have to write the tags There is a brilliant brief sentence that you should use it when they are not necessary, then they should use the Tag Tag Assistants. By using them, you are restarting all the punctuation marks they want to remove. .
