Question

I have a link

<%= link_to 'Add link', new_link_path(:link => {:item1_id => @item.id}) %>

passing to

def new
 @link = Link.new(params[:link])
 @items = Item.all

form is

<%= form_for(@link) do |f| %>
<%= f.hidden_field :item1_id %>
<%= f.collection_select :item2_id , Item.all , :id , :name %>

So I want to access like the image linked to the item1_id item. How do I access it?
i tried

@item1 = Item.find_by_id(params[:link])

and

@item1 = Item.find_by_id(params[:item_id])

but I don’t know what is right.

Answer 1

try:

@item1 = Item.find(params[:link][:item1_id])
