Jig: Am I doing it right?

[Summer White]

Learning Jig and how to use these mappers..

Getting data from DB into the hive for template use. I suspected that it might implement Traversable so I can could use foreach or <repeat> but it doesn't seem too.

Am I doing it right?

$mapper = new DB\Jig\Mapper($this->jig, "listings");
$mapper->load();
       
while (!$mapper->dry())
{
    $f3->push("listings", $mapper->cast());
    $mapper->next();
}

Not sure if what you're doing works, but seems like an unnecessary loop there.Try this:

$mapper = new DB\Jig\Mapper($this->jig, "listings");

$f3->set("listings", $mapper->find());

What I was doing does work, but really did seem like a lot of unnecessary function calls.

Cheers, this makes plenty more sense now.

I just revisited this code and using the find method returns an array with elements containing DB\Jig\Mapper objects.

This means I would still need to loop through and cast each to an array. How would this work in the template language with repeat?

Something like this?

<repeat group="{{@results}}" value="{{@row->cast()}}">

You don't need to cast it to use it in the template. just work with those objects ;)
This also gives you the flexibility to add some extra model functions that you can use in the template directly.

<repeat group="{{@results}}" value="{{@mapper}}">

<h3>{{@mapper.title}}</h3>
<p>{{@mapper->getSummary()}}</p>

</repeat>

I was wondering if foreach handled objects like that. But in retrospect its iterating through an array and just passing value an object. I hadn't wrapped my head around that part.

This makes me very happy though. Thank you!
