How to get button name from the controller in Rails?

I have a button:

<%= t.submit "#{ t('page.upload_image')}", :name => "image" %>

Can I get the name of button("image") from the controller?

You can't get html attributes in rails params. You need to send it in hidden_field which will be accessible in controller. 

<%= hidden_field_tag 'name', 'image'%>

Or you have multiple buttons, then you can write jquery on button click, assign button name to hidden_field and then submit form.

Jquery: 

$('.submit_button').click(function(){
  var name = $(this).attr('name')
  $('#name_hidden_field').val(name);
  $(form).submit();
})

HTML:

<%= hidden_field_tag 'name', '', :id => 'name_hidden_field' %>
<%= button_tag "#{ t('page.upload_image')}", :class=> "submit_button", :name => 'image' %>
<%= button_tag "#{ t('page.upload_image')}", :class=> "submit_button", :name => 'image2' %>

In both cases, you'll get name in params[:name] form.

Well this is how i do it:

<%= submit_tag "Estimate recordcount", :name => 'count' %>
<%= submit_tag "Download CSV", :name => 'download' %>

Then in the controller i check:

 if params[:download].present?
 end
