How to pass a parameter from input using button_to or similar

Hi everyone,

A short description of the issue. I have a one page app which displays a
list of items people can vote for. The tricky part is that some users
can add more than 1 vote because of their status. Each item is displayed
through @item.each loop with its picture, amount of votes and button
“Vote”.

<% @items.each do |item| %>


<%= product.name %>


<%= image_tag(item.photo_url) %>
<%= label_tag(“price: #{item.votes_left}”) %>
<%= label_tag(“left: #{item.votes}”) %>
<%= number_field_tag ‘quantity’, nil, min: 1, max: 10 %>
Vote

<% end %>

What I am interested in is in finding a way to send “number_field_tag
‘quantity’” value in request by clicking “Vote” button.

Just a note, is there any default Rails way to do that so I do not have
to use JavaScript?

    <button class="btn btn-default"> Vote </button>
  </div>

<% end %>

You can use a form. That is what forms are for.

Thanks, I though that logically forms should not be used to display a
list of tens items with different properties.

Will follow your advice, @Colin

Glad to be of help, there is no reason why you should not have a
number of small forms on a page.
In future though please remember to quote the previous message when
replying, I had to look back in my emails to find your original
message in order to find what you were referring to. Remember this is
a mailing list not a forum, though you may be using it via a

@Colin, thanks. Now I know one more trick and the reason to use it. Will
be quoting everything I can :smiley:
