589947 - Document renaming and redirecting

Status: VERIFIED FIXED

Description

[Erik Rose [:erik][:erikrose]]

As discussed in the "Questions regarding the Knowledge Base" email thread, we'll need page renames and redirects working such:


* Put the titles in the URLs
* Support the renaming of pages without breaking any links
* Have friendly wiki link syntax [[Alice the Article]]

URLs would look something like http://support.mozilla.com/kb/Ted-the-Title. Going to http://support.mozilla.com/kb/Ted-the-Previous-Title would redirect to the original article.

On retitling an article:
  Retitle original Document.
  Create Redirect(old_title, new_title)

On view document:
  if Document.get(title=title).exists():
      return Document view
  if Redirect.get(old_title=title).exists():
      return redirect
  return 404

On edit document (This part is P>1.):
  If there's a redirect with the same name as the title, warn that it'll be deleted if you save.



This should give us a simpler parser, fewer DB-crawling update tasks, support for renames, fewer special cases on document treatment (e.g., all pages should be treated the same in the l10n dashboard), and general UI happiness.

Have a "Previous Titles" (or something) field in some hidden away spot of the Edit view. Just a textarea with a line per title should suffice. Putting the UI on the Document will make it unsurprising that deleting the document also deletes any redirects to it.

We decided to spin this around and go with Wikipedia-style redirects.

Let's do the renaming UI as a separate bug: bug 600407.
