Converting Propel to JSON with linked entities

Question

I have this setup in a PHP project using Propel (which I'm new to).

User: userid, firstname, lastname

SignIn: signinid, userid, time

SignIn, in this case, is a table containing the times each user signed in.

What I want is to print out a JSON string using Propel of the last ten SignIn entries. On the front end I want to display something like:

Bob Builder signed in at 3:30pm
Max Power signed in at 3:24pm
...

So when I query the last ten entries in SignIn and then call toJSON, I'd like to have the User data for that SignIn record also included in the JSON.

How can I do that?

Note, if there's a better way to do this, I'm open to ideas.

Answer 1

One thing about Propel, is that the documentation is really clean, very readable and always helpful.

For your request, you can try the following request. Take a closer look at it, it's readable (as always with Propel)

$signIn = SignInQuery::create()
  ->select(array('User.firstname', 'User.lastname', 'SignIn.time'))
  ->join('User')
  ->orderByTime('desc')
  ->limit(10)
  ->find()
  ->toJson();
