Make sure post slugs are unique #15

Closed hmans closed 9 years ago

hmans commented 9 years ago

[x] Add a validation that checks if #slug is unique ~~within the post's day of publication~~
[x] When auto-generating a slug, append an incrementing number if the uniqueness check fails

While we're at it...:

[x] Validate that a slug is present
[x] Validate that slugs can only contain alphanumerical and some special characters (eg. _ and -)

I'm now checking for global slug uniqueness (within a user's scope). Semantically, it would have been much nicer to check for slug uniqueness within the day of the post's publication, but this would probably have given us a headache later (for example, how would we deal with a user changing their time zone, thus shifting day boundaries, possibly invalidating heaps of posts?)
