    <p>Populate takes the property name of the property you are trying to retrieve. This means that you should use 'hometeam' instead of 'hometeam.name'. However, you want to retrieve the name of the team so you could filter for that. The call would then become..</p> <pre><code>Match.findOne({}).populate('hometeam', {name: 1}).exec(function(err, teams) </code></pre> <p>Now you have a property called 'hometeam' with in that the name.

    1. COThanks for the reply. This gave me `"hometeam": null,` in the response and still only gave me one piece of data. Please look at the update to the end of the original post, I'm unsure why but if I try to print the name of the `hometeam` I get that error, `hometeam` is storing the `ObjectId` of the `Team` stored there. So how would I go about retrieving that `Team's` name?

    2. CO@germainelol Would you mind updating your question with the scheme for Team and Match? There might be either a wrong reference (the ref variable) or the ObjectId being pointed at does not exist. I suspect the former, but either is a likely problem.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
