To start off, the friendly_id gem allows your models to have “slugs” which ultimately help when you want your urls to appear more descriptive. For example instead of site.com/cars/43 you will get something like: site.com/cars/slug-name .
It’s better for SEO and IMO provides a better experience for situations where someone copies a link and sends it to another individual. When you see a descriptive URL you kind of know what to expect and it feels less threatening than site.com/?blah=92349&whatever=5959 ….. OR i’m just a wussy.
My current situation is this:
I have some STI models that use inheritance and want to use friendly_id with it.
The problem i ran into and erroneously thought was a bug can be found here:
https://github.com/norman/friendly_id/issues/167 . Basically when creating records for inheriting models i was getting duplicate slug errors. Something like: “Error: Duplicate entry blah blah”.
A quick answer the gem’s author, Norman, rained light and joy on where i had gone wrong.
So how do you get STI models and friendly_id to work together? This gist says it all and uses the idea of cars/brands as the STI model. Note: this is really only for example, if you have a lot of cars and brands you will probably want to model that differently.
Read the docs:
The gem’s docs are really good. While the docs for the FriendlyId::Scoped module explain everything in concise terms here they do not explicitly cover STI so hopefully this helps you out if you’re in the same situation.
