Reversing the effect of slugify()

[Ebenezer Olanrewaju]

Hi everyone,

I have a slugified the title of blog posts in the yabe sample app to form a url. To reverse the effect inside my controller, I replaced all - with space and it worked for now.

But i envisage when the title has other characters like ' which is also replaced with - by slugify, how can I get the correct title back inside the controller?

Thanks.

In general, it is not possible to do this from the slug alone -- because, as you point out, multiple strings can map to the same slug.  In other words, the slug function is not invertible.

If you first find the original post in the data repository (via a lookup on the slug or a lookup on a post ID), you can retrieve its proper title from there.

Thanks Matt.

I think i've gotten another idea. I'll slugify each title and save it separately. I'll use this to lookup the post.

Be aware of conflicts when you do that, unicity of the slugs is not guaranteed.

I recommend you to include the id in the URL, like that:
https://play.lighthouseapp.com/projects/57987/tickets/1215-add-sorting-to-getchoices

The slug is only here for a better looking URL, but routing is done
purely from the id.
