Rails - show last record

I am trying to show the last updated record of 'weight' from this DB:

DB structure

I am trying to call it using:

<%= @user.weights.last %>

I didn't get an error but I get this string printed:

<Weight:0x007f80814ab538>

Tried all sorts!

get last updated user' weights

@last_weight  = @user.weights.order("updated_at DESC").first

the result is:

<Weight:0x007f80814ab538>

And you need to show the attibutes of Weight in your template

<%= @last_weight.attribute_1 %>
<%= @last_weight.attribute_2 %>

What you see is a Weight object being returned. Try calling a field attribute on that:

@user.weights.last.weight
