Add string version of tag entity

[jadb]

I like this approach, let me know what you guys think.

This lets you do:

$muffin = $this->Muffins->get(1, ['contain' => ['Tags']]);
echo implode(', ', $muffin->tags);

So in a form, this should do:

$this->Form->input('tags', ['value' => implode(', ', $muffin->tags)]);

It isn't the prettiest yet but at this point we can either add TagAwareTrait::_getTags() which would automatically return the implode()d result or let it up to the users to use that in case they want strings or leave as is for multi-select.

To add the ID for their implementation, either do that when instantiating the table the first time:

$muffins = TableRegistry::get('Muffins');
$muffins->Tags->toStringTemplate(':id::label');

Or extend the TagsTable and define a custom $_toStringTemplate.

I think a helper would be the best way to handle the output of the tags. I don't like using the Table object everywhere. A helper would allow us to encapsulate all presentation logic properly an offer more than just a comma separated string. Here are a few examples:

echo $this->Tag->cloud($muffin->tags);
echo $this->Tag->string($muffin->tags, ['separator' => ',']);
echo $this->Tag->input($muffin->tags);
echo $this->Tag->select($muffin->tags);

The helper could use a template string just like the HTML helper for the cloud and tag string as well.

A helper on top of that is totally fine and actually the right way to go I believe.

@ADmad your feedback please? See the 2nd last comment up from this one.

This patch seems fine but it lacks tests :( I don't have the time to add them and @jadb seem to have been abducted by aliens.

@burzum Your helper prototype seems fine too. If you want to make a proper PR for it i'll merge it.

[jadb]

Am here, am here... just haven't been having the greatest of times, though things are starting to be much better.

I don't have time to add tests myself ATM, so anyone's help would be very much appreciated :smile:

[burzum]

@ADmad no time for it right now. I'm renovating three rooms and have a ton of work after my vacation.

[josegonzalez]

I can write tests tomorrow.

Maybe the aliens just gave him back a day so it appeared they didnt take him, though they now might have after all for good.

I implemented this in the new tags repo @ https://github.com/dereuromark/cakephp-tags Using a basic tag_list property to store and retreive as string. Works for forms, easy enough for most use cases. Rest indeed can be implemented on helper level.
