I’m trying to add tagging to my rails app – I’d rather not use a plugin/gem for this though.
My needs are pretty simple:
Users can add multiple tags to a single item, they can search for items by those tags, and they can see a page which lists all the tags they’ve used before.
What I’m wondering is, whats the best way to go about this? An array/hash in the model being tagged? A join table?
Any suggestions would be highly appreciated.
I would use a join table between the tags and the taggableItems. Then with a before_create you could check if the tag’s are already in the system and create them if they aren’t in the system. Next you could use searchlogic (i think there is a rails 3 branch on github) for easy tag/taggableItems searching. And it would be nice to give the user some feedback of the available tags with some autocompletion or a short list of most used tags but that is up to you/the design.
