Ember how to render value of key if the key is also an object in each-in

In my ember app, I have the following "each-in"

  <tr><th></th><td class="space-left"></td></tr>

Which renders my data i.e. customer_name Test example_one New

But I also have data is that is an object (another lawyer) right now it looks like so

drops [object Object],[object Object]

or

summary [object Object]

And the API returns different data so it can change, is there a way in ember to also render the child data so it's not showing object object
