How to add default value to a number_field in rails?

Question

I\'ve created a form

<%= form_for [current_user,@product,@bid] do |f| %>
  
<%= f.number_field :bid_amount %>
  
<%= f.n         


        

Answer 1

Just add @product.id to your field.

In this example <%= f.number_field :product_id, @product.id %>
