Counting the number of Parents related to a child entry

Question

I am using the example Relationships code which works but what I would like to do instead of showing the names of the Pizza shops is just show how many shops the Pizza is available at.

{exp:channel:entries channel="pizzas"}
    <h2>{title}</h2>
    <p>{description}</p>
    <p>{ingredients}</p>
    <h3>Where can I find this pizza?</h3>
    {parents field="specialty_pizzas"}
            <strong>{parents:title}</strong>: <br />
            {parents:phone} <br />
            <p>{parents:address}</p>
    {/parents}

{/exp:channel:entries}

I have tried this, but it does not appear to work, any hints?

{exp:channel:entries channel="pizzas"}
    <h2>{title}</h2>
    <p>{description}</p>
    <p>{ingredients}</p>
    <h3>How many restaurants serve this pizza?</h3>
    {parents field="specialty_pizzas"}
            {parents:speciality_pizzas:total_results}
    {/parents}

{/exp:channel:entries}

Answer 1

Try this...

{parents field="specialty_pizzas"}
{if parents:count == "1"}{parents:total_results}{/if}
{/parents}
