Sending enumerative parameter to a route from html template

Hello,
I am a new user in Phoenix world, and apologies for my naive question.
I am trying to generate links to Routes from HTML template like below and create issues while sending parameters. Could anyone suggest to me a suitable way for it?

<h2>Products</h2>

<table class="table" >
    <thead>
        <tr>
            <th>Product Name   </th>
            <th>Quantity  </th>
            <th># of Votes   </th>
            <th>Average Rate</th>
            <th> Link to Rate </th>
        </tr>
    </thead>
    <tbody>

<%= for product <- @products do %>
    <tr>
      <td><%= product.name %></td>
      <td><%= product.quantity %></td>
      <td><%= product.votes %></td>
      <td><%= product.avgrating %></td>
      <td><%= link "link", to: Routes.product_path(@conn, :create, product) %>
    </tr>
<% end %>
    </tbody>
</table>
