Adding Keywords individually

[David Novakovic]

Hey, I had a poke through the KeywordField source but I couldn't figure out how to add individual keywords to the string/set without messing around with save_form_data.

If I can get the general direction on the best way to implement this I'd be happy to do so..

Cheers!

Not sure if this is the shorted possible version, but here's a snippet that'll add a tag to a page/blog instance called "obj":

from mezzanine.generic.models import AssignedKeyword, Keyword

keyword, _ = Keyword.objects.get_or_create(title="my keyword")

obj.keywords.add(AssignedKeyword(keyword=keyword))

Great thanks mate. Seems like something that would be nice as a helper
method on the mixin.

Been spoilt by the various tagging libs out there I suppose :)

[Stephen McDonald]

Yeah that's a great idea.

I honestly can't remember actually!

I'm pretty sure all of my changes have been accepted into mezzanine proper now. If it's not there yet then I never got to it!

I did find some issues with dupes being added if you don't check them first.

Here is some code verbatim from a now redundant import on a client project (note, I think this works but you should test it first):

                for kw in keywords:

                    kw = kw.strip()

                    if kw:

                        keyword, created = Keyword.objects.get_or_create(title=kw)

                        if kw not in [k.keyword.title for k in recipe_inst.keywords.all()]:

                            recipe_inst.keywords.add(AssignedKeyword(keyword=keyword))

So I'm not sure on the best approach.. I would assume dupes are not desirable, but Stephen will no doubt be able to make an executive decision.

+1 this was a bit counter intuitive having worked with django-tagging and django-taggit before. Did you come up with a helper David?

Definitely don't want dupes - I have a weird suspicion "add" handles this somehow, but I'm probably wrong.

I don't recall either of us adding anything for this either. Would make a nice contribution :-)
