var_prefix message in ee 2.8.1 dev log

Question

I'm getting this message in EE 2.8.1 dev logs with Playa 4.4.5:

A template loaded on http://dev.tear.org.au/projects/ is using the deprecated {parent:url_title} tag. Please use Playa’s var_prefix parameter instead.

This answer helped, but not enough.

I've seen the var_prefix docs concerning the module tags, but can't find info regarding the fieldtype tag, which is what I am using.

My code looks like this (simplified):

{exp:channel:entries...}
    {project_content} <-- PLAYA FIELD
    {content limit="1"}
        <h4>
            <a href="/projects/{parent:url_title}">{parent:title}</a>
        </h4>
    {/content}
    {/project_content}
{/exp:channel:entries}

How would I need to modify my template to use the new parameter?

Thank you

You shouldn't need to prefix with Playa for what you're doing. You should just be able to use...

{exp:channel:entries...}
    {project_content}
        {content limit="1"}
            <h4><a href="/projects/{url_title}">{title}</a></h4>
        {/content}
    {/project_content}
{/exp:channel:entries}

The var_prefix parameter comes in handy when you want to do things like pagination for your Playa entries. You need to prefix it then so that it doesn't interfere with the main entry's pagination. But in your example, it shouldn't be required.
